I've read alot about setting the cross-over frequency for your receiver's sub out, but advice can be conflicting. Obviously, one can experiment and see what they feel sounds best, but I was hoping to get some opinions for this modest setup:
Onkyo TX-SR501
4 JBL N24 - 4" woofer, 1" tweeters, 75Hz - 20kHz (-3db)
1 JBL NCenter - similar to sats, but I think 60Hz - 20Khz
1 JBL Sub - 27Hz - crossover
Connected in the usual way, from receiver sub-out to lfe in.
[LFE in bypasses subs internal crossover]
Small room - ~ 15X10
Rule of thumb I've always seen is xover should be at least one octave above f3 point of speakers, which would make it 150Hz. Onkyo manual suggests 120Hz (based on 4" woofer - just a general guideline). 120-150Hz seems to be reasonable, but may be too high as it may allow the bass to become localizable. 80Hz might match, if the sats really do have usable output at 75Hz.
If YOU had this setup, what would you think is a good xover frequency to use?
