Okay, taking a hard look at the Hsu research vtf2 mk5. The 15 inch woofer on the vtf3 might be a little too much for my room size but I'm not sure. Thinking the vtf2 and the klipsch sub I already have will do what I need. Thanks for the help.
Oh no, my friend. The 15" will blend in very nicely. If you can swing the dinero that's definitely what I'd go with... er, did go with.
Those are a pair of VTF-3 MK5's.
I had all the same reservations you did, but I had already upgraded subs twice before (from Klipsch to entry level SVS) and this time I went with something I won't be upgrading for a nice long time. It's a hit at first, but a good vaccination against upgrade-itis in the future. I'm not a booming banging bass kind of guy. I let room calibration do its thing and give the subs a 3db bump like most of us do.
The bass is tight, musical and deep in all the right ways and thunderous when you want it to be. I thought I'd be using it mostly as a sealed sub, but experimentation with the different settings I discovered I like both ports open and a high q. There's a lot you can do with them tuning wise.
I can almost guarantee you you'll be shocked at how much some good, clean bass will make your whole system sound better across the entire range. I was floored. Even if you went with the PB2000 or the MK-2. Good clean bass is underrated. Upgrading my subs made more difference than almost anything I've done, including amplification.
I don't know much about your particular model, but the Klipsch sub (RPW10) I had was blown away by a
SB1000. That's entry level for SVS. It sounded so good by itself that I didn't even use the RPW with it because it made things sound worse. I got a second SB1000 and sold the RPW.
