This is SO true. The reality is - even from the artist’s vision - there is no fixed reality. Music is the art of the ephemeral. Nothing is fixed or permanent. From live performance, to recording and mixing and mastering, to speaker design, DAC implementation, headphone tunings, to EQ, to DSP, to different people with different hearing capabilities: we are living with live sound in live spaces and different situations…music is approximations, and close estimations. In this sense, we ought to embrace the differences rather than hold to music as fixed. Hence, there is no such thing as purity and we should enjoy the innovations and ambiguities of the auditory world and the meanings we can construe from them.

The concept of multi-microphone recording, like with the double-bass, is to have the possibility in the mixing process to be able to have all the advantageous parts of each microphone position and it’s corresponding frequency response/control of the recorded instrument and then to pick‘n‘mix those signals to (re)create a version, or even a very different creative version of the said instrument, in the example of the double bass, if present, the pick-up signal for very dry,controlled and transient rich signal, the close, or even in the f-hole for a harmonically rich but pure, so therefore very controllable in the fundamental „acoustic“ version of the sound, a microphone at say one meter to pick-up the „playing“ of the instrument with a „softer“ transient response, and, if required for the piece of music a distant microphone, or even a binaural one, to recreate the „ambience“ of the room or the perceived position of the listener, what is criticality is the time and phase alignment of all pickups/microphones after assembling the part(s) of each signal that you have chosen to assemble a realistic single instrument out of an artificial source, ie two or more loudspeakers. I must say as a professional sound engineer I do sometimes have a little chuckle to myself about some comments from audiophiles about the „purity“ of some recordings….and I think to myself, oh my, if only they knew…..“. There is a massive amount of signal manipulation goes on in between the instrument and whatever, the simplest and most direct way of taking moving air, turning it into moving electrons and back to moving air from an artificial source just purely because of its nature Alters the signal massively, even the (in)famous „direct to disc“ still have to go through mic/pre-amp/RIAA curve eq/cutting head driver amp……and let’s not even start with RIAA curves, extreme sad then smiley face eq‘s and an extremely hard single pole piece tracking a a v shaped cut in relatively soft plastic apparently doesn’t change the signal. Back in the days of am radio when mixing a song we made a 7“ mono mix, 7“ stereo mix, 12“ album cut mix, and if the time and money was there a 12“ 45 rpm mix, why might you ask? Well every Format had different limitations of dynamics and frequency response so….and people wonder why master tape to cd‘s sounded so awful…..yup, pure hi-fi……😂

'True-to-source' means getting the input signal out the speakers with as few non-linearities as possible. And since we weren't there at the recording studio the best we can do is use measurements where we know the input signal exactly. All that is left is pinpointing how the speaker's anechoic / Klippel measurements differ from the input signal and address it. AJ knows this of course and that's why he was confident enough showing the proto without even listening (as mentioned in the interview).

Couple of things I hope he would have touched upon more: a) as the midrange driver moves, doesn't that also affect the time alignment? b) what are his "personal preferences" when he finally voices the speakers. Does he like a more tonally rich or textured sound, or is it more about pin-point imaging and soundstaging for him...or something else? would be interesting to know...

It's a good thing Jones' expertise is in speakers and not cabinetry. The veneer on the top of the box should flow in the same direction as the sides. I suspect you did not have enough veneer left over to do the top properly but someone said 'Hey, if we rotate it 90 deg we can use up all our scrap veneer" 🤣
@johnpischedda6951 Жыл бұрын

@andrewjones6161 Жыл бұрын
You have it completely wrong about the veneering of the cabinet, but it's perhaps understandable if you haven't looked closely at the cabinet and understood how it's constructed. The sides of the cabinet initially go straight back, but then taper inwards at 3 degrees. Unlike fully rectangular cabinets, where the cabinet can be constructed from pre-veneered board and v-grooved and folded, the semi- tapered cabinet has to be veneered after construction. If we choose veneer directions similar to pre-veneered, with the grain pattern going up one side, across the top, and down the other side, the grain will not match at the corners and will appear mismatch progressively towards the back. In addition, with the pre-veneered method the sides will not be book matched to each other besides being upside down on one side compared to the other. If we choose to book match the sides, and then choose grain direction to run side to side across the top, then we will have absolutely no grain matching at one of the corners. By running the grain on the top from front to back, we break the concept of trying to match the grain at the corners. We built cabinets with all the different variants of grain directions, and the one we have chosen was the very clear winner. Of course, it's subjective, some people will have different opinions. But at least you now no longer need to "suspect" or speculate about our veneer choices nor my cabinet skills.

The diameter of the driver is 80%. Therefore the area is 64% and the volume is 51%. Having the same motor, the stroke will be the same. It is surprising that the parameters of the new driver perfectly match the volume of the proportionally smaller box. Is the veneer really 80% as thick?
