    I don't know that you'd really need a sub with those RTi12s, depends on room size and the gear you're using more than anything...

    What receiver/amp are you using?

    I have the RTi150s which are basically last year's model of the 12 (with some differences of course) and I've been comtemplating adding a sub for a while now. I think I've decided against it until I get my theater room built, then the only thing I would go with would be an SVS. I tried the PSW505 with my 150s and didn't like the combo at all, too boomy for me.

    If you get a sub, I'd get an SVS for sure. I don't think even the 505 digs low enough to compliment those 12s very well.

    However, depending on your current setup and gear, a sub MAY not be your best purchase to accomplish what you're wanting to do, hence my question about what you're running. More power on the 150s may be the answer, then again maybe not, will depend on your answer I guess...

    Or, if you want to stay Polk, the PSW505 can be had for just under 500, including delivery.

    I suggest before you buy anything you do a freq sweep using the 12's. Will a very good sub reach some what lower and be somewhat cleaner ? No doubt, but you should at least see what you've got and as a result what kind of bang for the buck, or not, you can expect on top of what you already have by adding a high quality sub.

    Lot of people including myself bought RT800i (RTi8 now) and then added a quality sub 'cause everybody knows that what a dedicated sub sounds like. Once you get a quality sub then those internal subs are wasted.

    You could've saved money on getting RTi8 and then spent on a sub. Combos are great but not always. Personally I would never get a speaker/sub combo.

    There are many great subs out there but you got to listen them first and let your ears decide. Visit your local stores and audition them. Don't make a blind purchase.

    I love my Velodyne CHT-15!;)

    The RTi12's do not of course contain a separately powered sub, but they do have 3 - 7" woofers ...

    Interestingly enough however the specs on the low end of the CHT-15's are -3 dB @ 23 hz and the the RTi12's state that they're -3db @ 30 hz ... I can tell you from my own sweeps of the 12's though that it's more like -3db @ 25 hz.

    Given that the original post stated that he already has a set of 12's, I would think if the quest is to really supplement the low end that he'd want to have a significantly better sub capable of fairly flat response at least down into the teens otherwise it would be semi pointless, wouldn't it ?

    We're in the same boat. I've got an SVS 25-31 PC+ coming to mate with my Athena Towers in a 2-channel only system. I did some sweeps on the Athena's alone (SVS comes tommorrow) and found that they roll-off fairly close to thier rated -3dB @ 35Hz specification. Though you can see the bass output begin its "fall" at about 45Hz.

    On Dr. Spec's advice, I'm going to start at 45Hz and see how they blend. Feel free to use me as your guinea pig with this, as your speakers are probably very similar in response to mine.

    I'll post my impression's tommorrow evening, after I've had all day to dick with the various settings....

    I love that..."man you got screwed, could have done it better this other way, I'd never have what you've got"...

    Nothing personal, I just don't get those comments sometimes...
