Re: subwoofer use for old cabinets
Don't high-pass the mains, let them run wide open. Low-pass the subs depending on their distance from the mains. If you only have a couple subs, make them flanking subs and low-pass them around 90Hz. Put the mains on stands, and put the subs on the floor...

Re: 1pi or 2pi for surrounds?
You might consider getting one of these:
Active Sub CrossoverSeems cheesy, but it really works great. If you are running a separate sub amp anyway, then this isn't much extra cost at all. And doing the mods is kinda fun too.
Just set the mains as &...

Re: 4pi Commercial Dinner Theater Build
Answers by numbers:
1. If I understood your picture properly, the west wall is on the left, where the mains are. So that would be where you would put flanking subs. Distant subs would be put somewhere else, more distant from the mains. The low-pas...

Re: Subwoofer hook-up
With a passive preamp, you pretty much have to use mains that have input adjustments in order to set the relative volume levels between mains and subs. This is true with active preamps too, if there is just one output. That's how I run mine - I have an...

Re: 4 Pi Speakers and 3 Pi Subwoofer Request Plus Question
Sorry, I must have missed your question about the sub crossover earlier. Here's a post from a couple days ago on that very same subject, with a couple links to products that work well:

Re: Subwoofer AMP
Certainly, that will work just fine. Tap into the preamp signal going to the amp for your mains, and run it to a sub crossover. I've tried several crossovers, and had good results, some better than others. Ironically, the one I like best for multisubs...

Re: Sub Crossover
Yes, I still use this crossover. I tried several different units but settled on this one.
