hey mbuck, going back to what Bill Fitzmaurice said, there isn't any advantages to getting tower speakers when you are using a good sub. What I would advise is get some bookshelf speakers for the front stage instead of towers. Check out the Klipsch RB-51 or RB-61, they will make a lot more sense when used with a sub. You get the same crisp treble with good mids. I think they are cheaper than the RF-42s as well. For a center, go for a RC-52 or RC-62.
For surround speakers, skip the RS bipole-type speakers, and just get bookshelf speakers, they will sound better and save you money as well. If you can wait, you can get the Infinity Primus p163 bookshelf speakers at Fry's for as little as $60 each, that makes expanding out to 7.1 really cheap. They are relatively powerful bookshelf speakers and sound great, so do not hold their sale price against them or think they are crap speakers- believe me, they are not. If you want good affordable speakers for surrounds now and don't feel like waiting for a sale at Fry's, check out the Behringer 2030p
speakers for $100 each, they are excellent, very high performers and very high bang for the buck.
For bookshelf speaker mounts, use the Videosecu side-clamping mounts
, I recommend these so much I must sound like a broken record, but they really are terrific mounts and extremely cheap too. They can hold 30 lbs speakers and you do not even have to drill screw holes into the speakers like most other mounts require. No other mount does that except for the Pinpoint Am40s, but those are twice as expensive and not really any better.
As for subwoofers, I would go with either the Hsu VTF2 mk4
, Rythmik FV12r
, or Outlaw LFM-1 Plus
. They are all around $600 to $650 shipped, and will blow away both the SVS and Klipsch subs, they are another level of performance. If you can afford more, check out the VTF3
, it is a low frequency beast, it can dig down nearly as low as humans can perceive low frequency bass.
