| Re: 20-39PCi vs. PB12-NSD.....???
I'm pleased to see a growing emphasis on FR correction. For the tweakers, REW and the FBQ 2496 are hard to beat for performance value and corrective power, and a flat in-room FR can make a huge difference in the bass sound quality.
Mac, the PB12-NSD is actually a very good match-up for the 16-46 PCi or the 16-46 PC-Plus, being tuned almost as deep (actual system tuning is about 17 Hz).
mrsollars: Think of the 20-39 PC-Plus as being worth about 1.3-1.6 (frequency dependent) 20-39 PCi. Otherwise they will sound/perform very similarly as low to moderate volumes. The largest advantage for the PC-Plus lies in the 20-50 Hz bandwidth, where the extra power, different woofer, and triple 3" ports give the PC-Plus about a 4 dB (60%) edge in clean output. Above 50 Hz, they are closer in max output, with the stronger amp in the PC-Plus being mostly responsible for a ~ 2dB advantage.
