[QUOTE="Frank Koenig, post: 97271, member: 416"] Re: 4 July Hi-Fi Amps are two Powersoft K-10 DSP. One for tops L/R and one for subs normal/delay. So all outputs are looking into nominal 2 Ohms. The plan is that the relatively small amp rack can live near the (typically) center stacked subs so that the speaker cables are short -- especially for the subs. I rewired the Danley inputs to use all 4 pins to utilize all the Cu in a 4 conductor cable. The Powersoft outputs come wired this way. 20 ft. (both ways) of 14/4 at 2 Ohms has .2 dB loss and a damping factor of 40 -- not a problem. Now, on the settings for the SH-46s. I'll tell you what I used but also tell you that this is shoot-from-the-hip preliminary and based on sloppy measurements. I have (grandiose?) plans to do much more refined measurements over a range of angles and some optimized fitting. If and when I do I'll share the results. Listen at your own risk :) SH-46 (2 each side) high pass (crossover): 4th order LR, 90 Hz high shelf: +8 db, 11.5 kHz bell boost: +7.5 dB, Q = 1.9, 6.3 kHz bell boost: +4 dB, Q = 4.3, 760 Hz gain = 0 dB delay = 0 TH-118 (4 in the middle) high pass: 4th order BW, 25 Hz low pass (crossover): 4th order LR, 90 Hz gain = +4.6 dB delay = 6.2 ms determined for this particular setup, additional 4 ms for forward end-fire pair no polarity flip --Frank [/QUOTE]
