LOL, at least some one else around here knows what they are talking about Maybe my first, or only, SVS being a PC13 has me overly enthused on the brand. Usually though if one model is outstanding the others can't be far behind. The PC13 is fast and accurate, playing deeper than the SPL12 dreamed of going, the SPL12 basically could rumble for home theater but never was musical in my opinion. Another ax I have with the Velodyne it died within a couple years, after warranty of course, I should have gotten a replacement amp but just decided to move on. I owned the
SPL12 and the PC13 was it's direct replacement so I know very well the margin of improvement I experienced, large.

On another application I am going to try an older model Artison free standing sub. Most of their subs are in-wall. The design is interesting in that they use two 5x8's firing at one another to some how cancel noise and vibration, the model I'm using will have 4 drivers and supposed to be equivalent to a 13" standard woofer. The sub is passive and comes with a stand alone 600 watt amp. The amp has a high pass crossover which I will feed to my stereo amp to drive a set of Artison on-wall speakers. I'll have to start a thread when all is up and running.

Big boys? The SVS PB13 Ultra vs. Velo SPL1500R? I'm still spending my money with SVS.

Pitting a PC13 Ultra against a Velodyne SPL (any series/size) is really not a challenge. I think the PC is refined in the 13 Ultra version and it puts many upper comsumer grade subs to task...sealed or ported. Just watch out for those DIY guys.
