Illuminati (1st Degree)

I posted this on the High Efficiency Speaker forum, but I thought some Pi speaker owners might be interested too so it's duplicated here. I reconfigured the speakers with the woofer and tweeter in the enclosure just as the plans specify, and the Beta 8 in a separate 0.5 cu ft sealed enclosure atop the main cabinet. In the process I remodeled the enclosures into an "art deco" style.

The Delta 12LF is now rolled off with a 6mH 16ga Erse Super Q inductor (0.27 ohms DCR). The woofer low pass filter now controls the midrange driver, with no chages except for the zoebel cap. The sealed enclosure rolls off the bass with a -3dB frequency of about 120hz. The tweeter high pass filter is unchanged. It plays really loud and clear with the 40 watt Audio Mirror SET monoblocks, and the 3 watt Paramours will drive it to room filling volume too.
