It's probably not a fair comparison, but I was able to hear the SVS PB 13 Ultra last night in a business colleague's HT. Was attending an out of town meeting. After the meeting, small talk ensued and we found out we're both HT enthusiasts. He kindly asked me over to give a look-see at his HT.
His room is about the same size as mine. And, it's furnished, more or less, about the same (carpet, few hard surfaces). He's got a 50" KURO (vs my 60"...got him on that count). Different speakers (he's got a total SVS set up). And, he's positioned his Ultra in a different location. I do believe I was more careful with placement on my subs. He just put his Ultra where he had room....no corner placement, but had it between his C and R speakers. Although, he did use the EQ of the Ultra.....one port plugged. So, this isn't very scientific, at all.
But, we used the same material I was familiar with.....SACD of DSOTM, WOTW, Cloverfield, Hulk. I'd give a slight nod to the Ultra for extension. I'd give a slight nod to the Phoenix for SPL. Neither one will show any untoward behavior when played at 100+dbs.
If I had to choose one over the other, I am a sucker for nice veneers. The Ultra does that well. I'd give the nod to the Ultra for the "eye candy" portion. But, you pay for that, given the $500 delta between the two. SQ, extension, SPL, tough call. Can't say I'd prefer one over the other. The Ultra is a really, really good sub. So is the Phoenix. That said, I don't feel the Phoenix gives up anything as far as quality of materials or build. They both do all things well, regardless of the parameter you choose.
Again, tough call. Can't make it based just on performance. Pocket the price differential with the Phoenix and forgo wood veneer, or spend the extra and get a nicer looking sub? That's the decision that has to be made.
