CoherentSource Service will probably also have carpet spikes, pointed and long enough to penetrate carpet.

gas - when the dust settles and we have accounted for the differences in effective series resistance of the new caps, coils and so forth, the frequency balance and phase response should be nearly identical to the original design. The improvements ...

J.A. - such considerations were an integral part of our development projects and accumulated knowledge. Wire effects are subtle and complex, but far from trivial. Yes, I agree that part of Jim's genius was to pay close attention to everything and ...

My approach is to identify and model exactly what each coil is doing and optimize toward the ideal behavior. That is different than choosing which sound I might prefer. Coils are quite technical in how their electromagnetic fields and therefore tr...

harry - big southern mansions have their charms. After my time at Thiel Audio I did some installation consulting work which included Bluegrass Horse Farm Manor Houses. The sonic potential of those rooms in those dwellings is a wonder to behold. 19...

holco - beetlemania and I have combined our resistor inquiry and included some things I know about brands from history. We are convinced that the MRA-12s are our first choice. Part of that choice is their patented technologies and the Aryton-Perry...

Yes, I would say the coax feed cap upgrade removes a slight coarse veil over the mid- upper frequencies. The MRA-12 Mills resistors add some ease. The drivers / cabinet have enough inherent quality to support considerably better XO parts. Keep up ...

harry - regarding 2 vs 3. The target frequency response is identical, including the upper bass x midrange. I suspect the difference you hear is based on power response in the room. The 3s go deeper and move more air. The 3s have a larger diameter ...

holco - you are welcome to share which capacitors you changed and why and your specific listening experience.

silva - I believe that you made improvements. I am merely addressing the physics of the cause. I suggest googling "speaker enclosure resonances" or somesuch and see what you can learn.It's quite complex - resonances couple when harmonically linked...

unsound - What you envision could be done with the SCS, but not the PowerPoint. The SCS has the same driver and XO, but its cabinet is made for 3D space.The PowerPoint's genius (patented -?-) is its 45° wave launch from a known, unobstructed plane...

Good work. I should comment that lowering the RF in itself hurts things. However, it is likely that you also decreased the resonances for net gain in quieting the cabinet.

I recommend you all find a way to audition a pair of PowerPoints on the ceiling at "normal" listening geometry with subwoofers configured on the floor beneath them driven by your hi-fi amp. That's my studio setup. I expect you to fall in love.

Regarding theater: I know a universe where the audio dimension of theater adds a profoundly deeper and more complete involvement to the video. As coherence enters that total immersion world, serious magic happens. (Little known factoid: Thiel work...

Great ideas, guys. jon - I highly recommend checking out USG Hydrostone instead of concrete, for reasons I've previously enumerated. rule - someone has to pick up the ball, I'll do my part.andy - good ideas. I suggest that Thiel's present driver t...
