But first reset the sub’s crossover to 120 Hz if it’s not there already and experiment with the phase switch on the sub – bass is affected if the mains and the subs products are out-of-phase: one setting will give you better bass than the other. Also, toeing in speakers, even subs, can make a difference.


I did that, it was set at 80. On re-reading the booklet I can still find, the one from BA listing the whole mid 1990's line, it said this sub actually has a variable range between 50 and 150 Hz, they only marked the 80 and 120.

I've also slightly angled it towards the center. DH's recliner has the prime spot smack in the middle of everything, my chair is a 5 feet to the right. I guess I'll also try angling the left front speaker towards the center, the right front points between our chairs.

Another question on that line in for the sub's amp (listed with a 75 watt high-current amp). My Sony doesn't not have anything on the back called pre-out and looking at the Yamaha 373 which is the a/v I think I will get, it does not have a pre-out either but it does have a single jack labeled sub woofer. It's not looking as though I'll be able to use the sub's amp either? would I even want to?

Sorry I've hijacked your thread.
