This is a gross simplification however good level matching can be tricky. If you have XT32 you can temporarily use the sub-woofer output to set the output level. I think the lesser versions will also do level checks but it's harder.

Fortunately this isn't the bipolar thread. While Audyssey isn't perfect the idea that a typical listener can level match and time align a multi-channel system by ear better than Audyssey is silly. Yes the buil-in amps make things a bit trickier but as long as the powered portion is close Audyssey will fix it up. Particularly if you don't make the mistake of running a center channel as LARGE/Full-Range.

The reason I ask is for the bass shakers they need a signal from the receiver's LFE.

Then you'll have to live with the potential problems of having both an internal (DT) and external (AVR) cross-over.

I will re-run Audyssey and just stick with what it sets my speakers to.

Thanks

I will...how can I do better with a radio shack spl meter? don't think so...)I tried the sub gain at only 10 o'clock and it was rattling my Verizon stb in my cabinet something fierce at some frequencies..will have to address that this weekend...kf

Hi Fanta, Snow, Bodosom., KMF etc,
There is quite a bit of discussion about Audyssey here. I want to chime in that yes, it's OK to use Audyssey with our powered center channels. The main reasons the warning about not using correction software exists is that, in our bipolar speakers, correction software can see the reflected output, which is slightly delayed, and interpret it as phase error, which can be confusing. The same thing can happen with our powered centers with a sub firing up and reflecting off the shelf above. I do want to reassure you that you aren't likely to damage either the speaker or your receiver by using Audyssey. It may in fact do a great job of getting everything dialed in correctly. Obviously our powered center channels have a lot of bass and mid-bass capability as compared to lesser center channels. So a crossover point below 80 (perhaps 60 or 40) makes lots of sense. In the current versions of correction software, you have more flexibility in where the crossover point goes, which is a good thing. I hope this helps - best, Joe

Bajawaverunner has a great deal now on the SuperCube I. About 300 less than the Rythmik F12SE (which I have talked about and not purchased for some time now...).

Is there a big drop off in difference between these two? From what I had gathered from other posts is the price on the SuperCube I vs. ID brands wasn't justifiable. And some say the SuperCube I is great but the Rythmik is just better...

Just wondering what people thought of that deal.

Thanks

Newegg was having a big sales on SC1 & SC2 back in January, they were selling the SC1 (brand new in box, not refurbished) for $600 shipped, SC2 for $400 shipped! I bought a SC2 for the bedroom at that time. And I just recently sold my old SC1 for $575 local pick up.

At those price point, the DefTech sub is a very good performance vs dollar sub even when compare to the ID companies.

But that being say, I think the SC1 +/-3db point is around mid-low 30hz only (about the same of the Mythos ST according to Chet). The Rymthik certainly could dig deeper than that.

But with the discount, now you are comparing a $1000 sub vs a $700 sub..... @<$700, the SC1 is an excellent value vs performance sub IMHO. But it's performance still can't compare to a $1000 (F12SE, or other equal value ID sub like SVS) one.

I guess it depends how much you want to spend?

I guess I should look at a $700 SC1 as about the performance of other $700 Internet direct subs.

But if you have around $1000 budget, there's quite a few other better choice imho. e.g. F12SE, F15SE, SB13+ if there's some size restriction. or VTF15H if size not a concern. All could have for around $1000 +/-$200 shipped. Depends on your requirement (sub size, room size music/accurate vs movie/output)

The "2010" BP series has reduced the gain on the rear-firing drivers which suggests to me that the market for the "bipolar" sound is not what it used to be.

There's real science behind our preference for the "spaciousness" imparted by certain reflections but true management of virtual reflections requires dedicated channels and (standard) speakers.
