I just sold my 320 to a coworker, and decided to go for the next in line, the 325. One of the advantages that I bought it for is the ability to change the crossover for individual channels. My sub is a Hsu VTF-2, which has good extension (25-100Hz) and a "Defeatable, true 24 dB per octave crossover, continuously variable from 30-90 Hz." (from their website) By defeatable, I'm assuming that it can be overridden by any bass management from the receiver, but if that's not the case, I'd like to know. Assuming I will be setting all 7 speakers to small (6 JBL S26 & 1 JBL S-Center), what should I set the crossover(s) to? Here's the pertinent info on the speakers, from the JBL website: S26 • Frequency Response (–3dB): 48Hz - 20kHz • Crossover Frequency(ies): 2000Hz S-Center • Frequency Response (–3dB): 75Hz – 20kHz • Crossover Frequency(ies): 800Hz, 3200Hz Anybody that's already played with this on their 325 or 525, let me know how you've been doing it as well.
