Thought about that myself, put the SB12+ on top, or on the other side of the TV with the SB Ultra 13. Loop from one to the other, then use antimode.

Good idea or not?

Bose Jewel speakers.

 

Jealous of my speakers?

My question is, would I be better off running all 3 subs or just the SB13 Ultra since it's so far and away superior to the other two?

Thanks

Try it and see or hear for yourself. You've got nothing to lose but a little time.

I was and still am surprised at the improvement I got when adding my Def Tech into my system.

Hi folks,

I picked up a new PB13 Ultra today. Unpacked it, set it up but aside from the quick set up guide, it had no other instructions. Is there an on-line manual that I can download?

You are likely to greatly improve your FR above 30/40 Hz. The problem will be in the deep bass where the difference in roll off between the sealed and ported subs cause them to be out of phase, resulting in bad cancellations. So for music it would probably improve things. For movies it would be a train wreck.

Man you are spot on, I have spent the last 2 days trying to balance the 3 subs and it's been virtually impossible. Doesn't help that I need to keep relatively low volume levels (2 year old) so testing bass heavy scenes or test tones is tricky.

I eventually just went to the Ultra by itself and have been focused on getting it dialed in perfectly.

LOVE it so far, it actually sounds fantastic even at relatively low volume levels with BOTH music and movies. Amazing sub.

But I keep wondering how duals would sound...can't get it out of my mind enough to even enjoy the single SB13 Ultra

Congrats!

With dual subs, stack'em in the corner and put on a jockstrap. Don't want EVERYTHING in the room jingling!

I think you are on the right track....get it set up as good as you can with the single ultra. And yes, duals will sound better especially for music. From what I have seen, one sub usually gives a pretty good response under 40 Hz, but very uneven above 40 HZ. So for movies, you mainly gain headroom in the deep bass with dual subs, but they give a much better quality bass for music due to the flatter response you can get.

I suggest your next step, if you are serious about having great bass, is to get Umik-1 mic from miniDSP, download REW, and measure your room. For $75 you can check you in room Frequency response and determine if you need to adjust placement or if a second sub is really needed. I was happy with one sub until I measured the room..........

Hi folks, I'm going to look at buying a used pc13 ultra, and the seller is willing to demo it for me before purchase. Is there anything in particular I should listen for or visually inspect in order to ensure it is okay? Any common problems I can check for?

Also, it is an older model with the Bash amp, is there a significant difference in performance or anything else I should be worried about with it?

Just a little less powerful. Nothing substantially different.
