Going to get a PB13 Ultra, to go with my satellite system. Hopefully it blends well...

I'm with you on this as at first I found even the SB12 big. But now I feel I could have put something much bigger in its place and it wouldn't have made much difference. The problem with the PB12-Plus for me is not much the height or width, but the depth. If you keep the back (connexion, heat sink, etc.) a few inches from the wall, and you keep the grille on (2" more), you end up with about 30" of ingress toward the center of the living room to manage.






250 W is the max (RMS) that the speakers can take. It's wise to have speakers that can take more than what your amp can deliver. The A5 are modern, easy to drive towers, with 8-ohm nominal impedance and 90 dB sensitivity. That means that 1W will get you 90 dB right there (at 1m), and each doubling of input power will add 3dB. In a realistic scenario, most of the times you'll only use a few watts per channel. But the most power-hungry part of what you play will be handled by your sub anyway. So if budget is not a problem, go ahead, you'll be totally fine. I have Energy RC-70s, which are in many ways similar to the A5, and drive them with a similar (but slightly crappier) AVR

Running dual subs helps in evening out the room response and offers a better uniformity if you want good bass throughout your listening room.
And I'm not disparaging the Ultras here: my mouth waters looking at those. What I like best in the Plus and Ultras is that they can be tuned at either 20 Hz or 16 Hz or be sealed. This is why I'm considering dual Pluses now.

Soo shipping is quite a biggie. The Submersive costs me $985 for shipping.... crazy ae? But even still it only ends up being $200 more than the Ultra. The Ultra costs me 3.2k and the Submersive (Original, Standard finish) 3.4k. I will definitely not consider a finish which will cost me more for the Seaton. Far too costly, esp. the polish.

Anyway there are multiple options and it's not like the sub wouldn't work without EQ. If you're going with the Ultra and plan on using its PEQs, you can "manually" plot the frequency response if you have an SPL meter by playing tones and noting the SPL at each frequency. Then you'd know where to apply the Ultra's filters. So a first step would be to get an SPL meter -- it's always very useful for calibrating subs anyway.
