Re: ZMAX figure for very low damping factor amplifiers
Wayne, I like to thank you for all your help. Would building the Seven Pi - 18 Cornerhorns be worse than the 15" 7 Pi for the amp I'm using?

Re: ZMAX figure for very low damping factor amplifiers
Of course, the cabinet will modify the woofer impedance curve substantially, but if used in a reflex cabinet, I'd still try to find a woofer with free air Zmax under 50 - 75 ohms and woofers for sealed cabinets probably should be even lower. This is impor...

I vote for Delta15 and Theater Seven Pi
Hey Super BQ,I found the Delta15 is a good compromise of price and performance and with 52 ohms Zmax, it is good for tube amps too. Wayne's designs can handle a lot of power but because of their high efficiency, that's another reason they work well with l...

ZMAX figure for very low damping factor amplifiers
I've been told to look for a woofer that has very low ZMax figure. What range of ZMax figures should I be looking in 15" or 18" woofers? What trade-offs are there to using an extremely low ZMax figure? I see the cheaper models of woofers have a lower ZMax ...

Re: Son of Zen has highish output impedance so low Zmax
Yes my SoZ amp has a very low damping factor. Maybe i'm using the wrong kind of amp as it seems like these Pi speaker are more suited for concert / outdoor use with BIG power amps. The only audition my SoZ has ever had was with a pair of B&W 6P speakers. T...

Son of Zen has highish output impedance so low Zmax
Hey Super BQ,Homer: "Mmmmmm Super BBQ ..."I recall that all of Nelson Pass's DIY amps (Zen, Son of Zen) have a highish output impedance (just like us tube heads); that is, a low damping factor. Thus you'll need a speaker with a low Zmax.So check out Wayne...

PSD3003, wrong graph
Hey Wayne and Chris,Very nice page!Did notice one small thing: the PSD3003 graph looks like the PSD2002 graph. The eminence site has a different graph for the PSD3003.Hey Paul C., the Thermionic series is for us tube heads (low Zmax for higher output imp...

Re: piAlign software and figuring Zmax
Hi Wayne!Since you brought up the subject on the high efficiency forum, is the port length calculated by piAlign the corrected length Lc for the port volume? ;P If not, how can a humble soul determine the correction factor?Also, I was looking for some idea...

Re: piAlign software and figuring Zmax
PiAlign suggests a 4 cubic foot cabinet tuned to 37Hz for the TAD 1602. So the Pi cornerhorn bass bin for it is a little over three feet tall. Bracing, wood thickness, the port and drivers inside displace some volume, so the cabinet is made large enough ...

piAlign software and figuring Zmax
Hi Wayne -- I have been experimenting with your piAlign program and a few different drivers. I looked at the TAD 1602, but that was a huge cabinet solution. The TAD 1601c at 102 dbW/m turned out to be a very attractively sized enclosure. I have a few detai...
