Well I appreciate you asking me that. My thoughts are that, even though I agree with you, and did consider the benefits of 4-10’s vs 2-12’s. I believe he’s dealing with one seat, and I feel like the PC2K pro’s will be able to deliver more output and TR. For me that’s important.
The speedwoofers are probably the best 10” sub, and maybe the only one I’d personally consider. The SVS also have a form factor that I like. I think they look unique, and really like mine. Another thing is, setting up four subs is. No joke. As you know with your pair, it’s a long way down the rabbit hole. Lol
Hope that helps! Can definitely add more...
