So, last year I finally got some money together to put together my very first home theater. I Polk monitor 60's and 20's front and back, and a Polk center (forget what model.) My subwoofer is an old Acoustic Research 100W down firing 10" ported sub. It has been with me for many years, and is pretty trashed. It makes a bad popping sound during peaks in subwoofer volume, such as explosions. I think it's time to think about replacing it. Crossover is being handled only by my Yamaha receiver.
I do however, have an olllld Adcom GFA2, which is 100WPC sitting around collecting dust. Can I:
1. Try the Adcom to power the sub instead of the sub's internal amp, to rule out a blown sub amp?
2. Use the Adcom to power a new passive sub? (is it powerful enough?)
3. Simply buy a brand new, powered sub.
If option 3, should I be looking at another placement, or sub type to optimize the sound? This will be used 80% for home theater and games. Also, I only have a budget of less than $300 for a sub, so I'd like to get something that is good value.
My layout is attached. The room has a carpet floor.
