Re: Flanking subs
Your flanking subs should work well there. I visualize the mains on stands, toed-in 45°. The flanking subs are just outside, on the floor. Each of the mains and its flanking sub are pushed out nearly to the side wall. This is a good setup. Then put ...

Re: Is the difference in sound quality all in our head?
That's all very true, Rusty. Glad you posted it. The audibility of distortions and anomalies could be and should be viewed as a weighted set, with the most audible things factoring in more than the least audible things. It's relatively easy to mea...

Re: Analog or digital audio?
Both technologies have advantages and disadvantages, and the best systems exploit the strengths of their core mechanism and limit their weaknesses. The strength of an analog recording is it has the potential of being a perfect copy, but its weakness i...

Re: Pete's Home Theater Build
You're right that the benefits from the JBL driver are much more pronounced in the four π speaker than they are in the seven π cornerhorn. The woofer is low-passed at 250Hz in the cornerhorn, so much of the gain from the flux stabilization ring is unu...

Kits include the speaker drivers, the connector panel, hook up wires, "π" logo decal and a printed copy of the plans. For larger speakers that incorporate a compression tweeter and crossover network, kits also include the crossover, Zobel woofe...

Re: Audibility of Phase
We are definitely on the same path and these are good words for refining the point. I guess another way to state this would be that speaker POLARITY effects both phase AND non-linear distortion. Since our ears are phase agnostic, this leaves the distortio...

Re: Audibility of Phase
You're right about the condition that exists at high drive levels. You and I have discussed this before. At extreme levels, where a driver becomes non-linear, some (most) act differently in one direction than the other. I've seen that in woofers in pa...

Re: Is 16/44 high enough?
I can see other possibilities as well, such as overall rise time changes? Whatever it is, or combination you and I have pointed out, I would rather be on the safe side. Here is some more information from Dr. Kunchur's papers. "The temporal ...
