a systems engineering approach should always compare the output with the input, including impulse response. Sure a hyper well executed high efficiency driver using best available materials, engineering, machining, etc are expensive. I think any reputable end speaker company designing own drivers, even semi custom w Scanspeak, are similar $$$$$. Some of those take into consideration that output is not a measure of quality.
I also believe, no designer should ignore ear brain. Many just sell distortion we like. Flavorizers.....
sure, the holy grail is low mass, breakup far from the passband, pistonic, with super high strength motors and high duty cycle....nothing has changed....
also, as an ESL owner, I think about the sonic impact of transformers and edge clamping distortion as well as energy storage in the panel....ain’t no free lunch
glad the conversation has returned to civility.... |
voicing in a chamber would ignore room gain and reality, it’s a great tool for matching to a standard ( impulse, freq response, pair matching thru nulling ( hint ), etc.
For those dealing in the reality of listening in a room, RT 60 is the path to better sound. |

i spent a decent amount of my career in anechoic chambers testing advanced technology, simple stuff , some suborbital. my prefered vendor of loudspeakers ( since 1977 ) actually have and use a chamber for development and importantly production, doing the precise work of tuning to a standard and nulling. Do you have a chamber ? |
the natural world is full of diffraction, most sterile audiophile rooms lack it bigtime...except for the forest of amplifiers blocking the path to the turntable ( which should be off to the side ) |
reread my post, i said zip about anything but absorption. take another run at finding a 6” absorber in nature. Its a hole in the acoustic space the brain is trying to reconstruct. I am a principal in a recording studio with a mobile location rack. You can catch up later. |
an unnatural treatment of room will also cause your brain to work harder....just evolution...find examples in natural environments that display broad band absorption like a 6-8” deep panel.... they don’t exist.....
ES, you will eventually tumble to time and phase.....

Duke - IF you can say, are you 3D printing the waveguide ?
best to you in 2021

do give some thought to the amp and speaker designer engineering an easy load and then further optimizing the amp for that load....just 5 parts in the signal path...
and for the measurement camp, both measured by JA
and for the flat earth science denial sect, he loved the sound. |
nwres I could have said one designer at least gives you lower distortion with lower sensitivty as a byproduct AND an easy load. Since 1977. |
there is plenty of money in a $50k plus speaker for fine drivers with best available energy in the gap Ralph, actually make that $15 k for Vandersteen Quattro, throw in built in subs w 11 bands of EQ and an easy to drive load
One reason why Thiels don’t sound like Vandersteens, before the Mafia attack, I own both. BOTH. and Panels that store energy, electrostatics that sound like transformers....etc...
its a brutal truth, move the accuracy ball forward or flavorize. Just know what your religion is...ha.
enjoy the music....
|
Also don’t confuse low sensitivity with a poorly engineered load ( bizarre phase angles, super low impedence, etc...
or a bunch of series / parallel connections.... |
So building a dead box.... cuts output..,,
shall we go on ?
the big baffle can be thought of as a 2D horn ....
|
Also the box flopping around also adds to output, just not in time with the note played .... |
Chasing flavors of distortion aka cone breakup or the focused constructive and destructive interference of a horn does not move accurate reproduction forward. Nothing wrong with picking baskin Robbins flavor #426 if that is your thing...
pistonic motion cuts 3db off sensitivity, ain’t no free lunch |
