I have passed from little forty years and?a 20 that are gotten passionate of. Between ups and downs, some autocostruzione without pretensions shooting ahead. Unfortunately from young person I watched pi?e girls of the books, and this has prevented to me to have one technical formation. They are enrolled to a Mailing relative List to HI FI, and of recent?ata an argument on the "absolute phase" of the sonorous wave they allegate that if marks them reproduced from a loudspeaker invert of phase of 180. regarding it marks them electrical worker originates them?dibile in some cases like one. I have not very understood what I agree for "absolute phase", having a not exceptional system, but however good, I do not feel difference between the two conditions. I would be curious to read its opinion in merit, inasmuch as I have read to some of Its articles (years ago) with much interest, perch?a always demonstrated with measures and diagrams ci?he it has written, and in pi?ono be one of the many that have listened to ESB 7/06 without being able them to per?ermettere, unfortunately. If not if of?ncora shrewed, I estimate it very, and me dispiace poterLa not to pi?eggere on the reviews audio (than I do not buy pi?a time). he marks them acoustic are of ondulatorio type. from one sequence of increases and lessenings of the pressure of the air regarding. Like the waves in the sea, the acoustic waves propagano. We imagine an acoustic impulse costituito.da an express increase of the pressure, followed from a "bounce" negative and a successive return to the valor medium of the pressure. In order to reproduce a similar wave a loudspeaker would have before to move a lot fastly in its direction in order then to return fastly behind and then still little in ahead species of short would feel one "toc". the succession of the motion of the loudspeaker. "invert of phase" of 180., its acoustic feeling instead would be the same one, also se.alcuni investigators support of to have demonstrated differences employee from modalit?i the operation of our auditory system viceversa obvious to attend differences to cause from are also minimal, asymmetries. Object: Reading to its interview with Francisco Pigeon still I with my eternal indecisione on the cases to buy a series of acquired reasons it is listening, it is from technical detailed lists are much legacy to the production planned from Renato Giussani (on purpose the 80 LD with woofer with suspension in rubber was that one planned from She friend of it has a brace that played just OK hour is trying to rifare the suspension the Canine Woofer but the kit they are unavailable and as usual we will have unfortunately to send them to the usual of which we have optimal knowing news from several and the reviews but it is to Genoa and we to Bariums). Me dispiace farLe to lose time but I repeat that the feeling of spazialit? nature own of the 2 cases of series 7 from me listened to (the 7/08 does not know which series and of how many ways, and the 7/06-II) has not still found a valid one avails again, also having up to now listened to many other good realizations (SEES THIEL series 7, Quad ESL, B&W - Nautilus, Martin 802 Logan - Quest, Klipschorn, and many others also of advanced cost and name comprised Acappella.

In order to make it short: currently, also with the thousand doubts legacies to my atmosphere of I listen (and that for hour they have been the true problem for which one or the other is not still in house mine) does not know if I succeed to find pi?almeno the 7/06 series ready available (that is if the owner from me contacted the last time 2 months ago has sold it).

That is the resonances were such not to make to obviously come outside not minimal differences if with my Dynaudio Craft (2 ways with 28mm tweeter a Esotar and woofer a Dynaudio from 17 cm come to an agreement in reflex front, little pi?randi of 1, Contour mount reader Copland 288 and pre+finale brace AES 3 + 1). of having of the foolish cases but I waited for to me that NPS III are better the other other models propostimi are FOR ac 3, (those nearly from pavement) that they have a particularly warm sound. I do not succeed to understand if NPS III that also are to house Its (in a various room from the 7/06 but creed also from the NPS-1000) are for nature and spazialit?aragonabili to the 7/06 or quite more better seen the fact that they use the NSP, or are alone the derived diffusing usual from 1000 that then completely effect NPS (too many resonances) and gave to a cold stamp apparently seppur much pleasant one to it (to difference of series 7 that?alda) and above all gave the impression TO LISTEN TO an optimal SYSTEM HI FI even though but not of being in front of the musical event that my CD of reference are masterizzati and were illeggibili for. It has to me gi?isposto in part to these questions (the 7/06 is pi?ndicate for its tastes, buys a pair of 7/06 and lives happy). bed many years ago said that NPS III had one great sound and for sure backs the NPS regarding the optimal DSR. also emerged all superiorit?ell' would still want a also dispassionate rispostina (or perhaps gotten passionate personal to these questions and in particular also regarding the positioning in an atmosphere of I listen to much asymmetric one that second It would not have to give. the Dynaudio that they have a SPL Max pi?asso regarding NPS III) obviously succeeds to strongly play without to distort. Finally: I have read on the article of which over (interview of Francisco Pigeon) that between the references of the times in which the 7/06 they have been planned there were the Yamaha ns1000, Than between the other (Deo Gratias) I think is a highly atypical diffuser regarding the other Yamaha even if somiglia aesthetically. I this diffuser have listened to it in house mine with my electronic ones for some days (I am of a my friend who not if it would separate never) and it went some indeed well, much natural and dynamic epi?aldo and suit on the upper-middle one of mine, with a articulation on the bottoms totally disowned to the Craft (were not of pi?lmeno to the volumes to which it could itself be arrrivare with the Craft, but a lot, many pi?rticolati). memory, as it sees 7/06 or NPS III regarding Yamaha NS 1000 that could perhaps be the only alternative to the ESB or Audio Aedon (sells them one. Precise that that the Yamaha to house mine in order to play in symmetrical way had to be advanced at least 1, bottom from the part where the wall there?ed also the angle) perch?ltrimenti, also not introducing some contraindication in the emission in vlf, introduced a totally asymmetric sound on the perch?ei means sure knows Them more better than me) that the Yamaha they are wide little pi?ei Woofer (from 30 cm of diameter) for which ca 35 cm while the ESB and Audio Aedon are respective 46 and 48cm (cio?iniscono still pi?n angle of the Yamaha) We hope well (the Dyanudio are wide the usuals 20cm).

After an immense experience anniversary in the field of the elettronica(Radio, TV-Color, Videoregistrazione, Computer, Hi-Fi, Car stereo), me meeting to recover two woofer "mythical" RCF L15P/200 dismessi from a discotheque of mine citt?ritrovo projected behind in the time to leaf through the reviews still very conserved in order to plan a case for gli.Ritrovo with appeals to its name, and in the deprived of hope attempt to find those "dated" BASS-PC ", me meeting to being able to unload it from its situated Internet. Without dilungarmi too much: one of my dreams then was of autocostruirmi two diffusers to high efficiency and one. Hour with the RCF I wanted to try to construct furnitures to me in wood with BASS-PC, that it works very well under Windows. 1 - The woofer in my possession L15P/200 are siglati, exactly like those brought back in a catalogue RCF to the inside of AudioReview di.quegli. Hour the RCF produces the same woofer with one various acronym: L15P200A, K and from the brought back parameters of Thiele/Small also in the database of the software, famous that are of. Not task that these depend solo from the fact that they could be measured from the alive one from. In the planning of the case I must keep in mind of the brought back parameters. 2 - Between several the plans of case reflex to disposition to which it advises me. 3 - Having to disposition two cases of 150 liters gi?atte from a my friend, inserting the parameter in the software, I can realize the modification that me. From the several tests carried out me seems feasible. Not wanting to tire it beyond with my dreams of infancy, ringrazio it for its disponibilit? for the possibilit?i to have been able to unload. I would be much happy one if it could give to some council anch' I to me to the beginning have been "gotten passionate" of autocostruzione for. Inasmuch as you have of the doubts on the effective value of the parameters of Thiele and Small of yours woofer, perch?on them measures, cos?otresti to carry out a plan from turn out to you. All the versions of the Bass program (comprised that one for C64) preview a breaking in ruotine that assists in the survey and the calculation of the entire necessary set of parameters for the successive use of. In order to pass without indugi to the measure, memory that must be equipped of a vlf generator to us that covers also the band from 10 to 100 Hz, an amplifier of power from at least a pair of watt, a voltmetro electronic, a ohmetro with the scale of Ohm x 1 or at least able to carry out measures of the 10 inferior resistances to Ohm with at least a figure decimates them, a weight gives approximately 30/40 grams (if ring-like) more better not ferromagnetic, a righello pi?ungo of the diameter of the loudspeaker with subdivisions in milimeter, one resistance from 1/2 8,0 watt Ohm and one resistance from 1/2 watt or pi?a 3. Per.primo.cosa you must measure the resistance of the coil in cc. The escape of the amplifier, the resistance and the loudspeaker, supported in horizontal must be connected in series on its magnet on a heavy plan and very. The voltmetro it goes connected in parallel to the loudspeaker and then you must first of all proceed to the calibration of the scale of the voltmetro connecting the resistance from 8,0 Ohm in place of the loudspeaker. You choose a frequency around to the 100 Hz and increases the tension until when, on the scale from 1 Volt of voltmetro law 0,8. Then Ohm reconnects the loudspeaker in place of the resistance from 8 and executes all the sequence of. You memory that the equivalent diameter?uello that suspension from both sides of the diameter clearly comprises the diameter of the cone pi?et?ella. The frequency of resonance?uella to which the stiffness catches up a relative maximum the F1 and F2 is hardly to of under and above that one of resonance and is those to which the stiffness assumes the indicated value. Naturally, in order to carry out the reading of the 10 advanced stiffnesses to Ohm, like also in the case of the reading of the stiffness to 1 kHz, you will have to go up with the scale of. It makes me to know if you meet difficolt?da part mine prover? to put on-linens one of the articles in which I explained step step all the procedure of.

I in the first place wish ringraziar it in order to have been able to dedicate a po' of its time in order to answer to me, oltretutto in cos?empestiva way. I must confess them that I have still some doubt on that solution to adopt for. Premetto in the first place that the week before finding BASS-PC I have tried to calculate the piece of furniture with other software to freeware and to shareware finds to you in Internet in situated Americans, but the various ones turn out obtained to you and the impossibilit?i to understand on which systems the good calculations were based me hanno.Avevo considered the data supplied from the RCF, like from she. It would appeal to to me to be able to measure from alive the parameters of the woofer, but I would not succeed to find of the time because of my job software, my choice had fallen on the system reflex B4 poich?non knowing the difference between several the systems, had obtained the best extension towards the inferior limit of the gamma.Avevo obtained an inferior frequency -3dB of 43.Gli other systems had discards them you for the insufficient extension towards the bottom observed from the diagrams risultanti.A to say true the best extension in frequency was obtained with filtered the B6 system, but the realization would begin to being pi?omplessa.1, like evince from the manulae of the program, would demand an equal Qts to 0. and, although mine woofer it has In short these my final considerations:. - varying reflex: volume case reflex 150 liters (in place of the 96 calculates to you), for being able to take advantage of of furnitures gi?atti. made, poich?ono it realizes to you with truciolare of average densit?pesso 2 cm very glue nearly without trafilaggi and therefore Them I would be much pleasing one if it could give still some council to me. All good would go, if it were not that between the 96 liters it calculates you from the the 150 program and available the difference?Che excursion and answer curves calculates the program then calculating all for the chosen QB3 and changing only the volume and even also the Ql (the factor of merit of the piece of furniture) reducing it a volume to the inside of the furnitures that possesses gi?on of the bulkheads in wood or volumes. I enclose the three diagrams turning out from the calculation with system reflex QB3 n. For? this point me dubbio:ovviamente rises an other beyond to the extension of the answer in frequency changing several the parameters very changes also the way to play. As "sound" said she - not. It could explain to me in little words, if possible, the substantial difference between several the systems of agreement. I hope just that it can help me, otherwise if the thing began too much to being complex and of disturbance for she prover. I had gi?isposto, increasing to the volume the answer it changes enough, above all in the shape, less rounded off and graduates them in the cut. A lot per?a not to render it not. What I said approximately the sound hi-fi than less sure reflex reported to the fact that when the answer in frequency in the pressed ones of the cut introduces a course pi?ipido, even characterized also from a localized emphasis, to I listen to easy pu?omportare the classic feeling of the "bottom.

In the case it wants to replace it would have to know many other parameters. Diameter and stiffness are not absolutely sufficient in the first place ringrazio It for its precious suggestion. For the ribobinatura It has some address to suggest to me in Milan. In the case a supplier for the substitution, in attached wanted to advise to me trover?e characteristic techniques cos?ome supplied from the house.

In the plan of the case, then, I reinforce of lowlands?vviamente held in. The expectable result?olto, with pi?acilmente low many pi?egolari.Giussani, is a happy utilizzatore of "its". Putroppo creed is time to change the loudspeakers (woofer and mid-low). to I listen do not notice defects but the rubber of the suspension introduces many leaks on all and the four devices you. The council to try "to delicately reinforce" the suspensions of the loudspeakers with vinilica glue applied a lot with a pennellino, before that. If the suspension of the woofer had to yield potr?empre to make to replace it, while for the mid-low?n po' pi?ifficile perch? much light, even if not impossible one. The loudspeakers are not sostituibili. In the previous one mail I had forgotten to ask, since some day f?o had way to listen to a system to two ways online of transmission, which (s)vantaggi. such type obviously to bass reflex and the perch?ale solution?ommercialmente little. If such system knows a situated one where?en. Me excuses a lot for the eventual disturbance.

The result?na acoustic answer to the vlves much objective and subjective extensive one, but with one sure attenuazione..pi? less obvious localized to one double frequency regarding that limit. the game is based on "compromesso".fra the two effects (reinforces and attenuation), that it depends on the length of the culvert and the type, from the quantit? on the disposition of the sanitary napkin in the culvert damping the culvert depends nearly exclusively on the Q and the gi?itato "compromise" (, wants or you do not want. ago I have been able to listen of the Tandberg cases that to I listen turned out very.
