I'm sure PSA quality is better than what is in the local stores but I think I'm addicted to the tight (fast), accurate servo design.
How tight and accurate is the V1800 (I assume the V1801 will follow suit in that area)? Should I be looking at Rythmik, Velodyn or a sealed PSA instead of the vented to get quick, tight and accurate?
Forgive me but when I hear terms like fast, tight and accurate and I can't help but fear that PSA subs (V1801) will be like some the flapping noise boxes in electronic stores that I've seen.
This makes me cringe, especially fast and tight, tell me what these terms mean and I'll tell you if you should stay away from PSA subs. There's nothing fast or quick about a sub's performance, if you mean the difference isn’t in how quickly a sub’s woofer cone gets moving, but in how quickly it stops. In low-Q subs, the cone tends to stop almost instantly at the end of a bass tone. In high-Q subs, the cone tends to “ring,” or continue moving back and forth after it was supposed to have stopped.
Now if that's what you mean about quick and fast, yes a V1801 will do that in spades. As the saying goes "as long as they play loud with minimal distortion and have enough low-frequency content to shake your couch" that's a good subwoofer, these are your flapping noise boxes, one note wonders. My 1800s will dig deep with authority when asked too and at the same time if you put on a recording in which the low bass has specific, deliberately chosen pitches, maybe a tune with a melodic bass line with subtle nuances, you should start to hear some differences between subwoofers.
The larger driver PSA subs 15-18", to use your terms are just as quick, tight and accurate as your smaller 10" servo controlled subs, have greater dynamics with controlled accuracy whether being played loud or soft and do this at extreme output levels without breaking a sweat. Two myths are busted here, sealed subs sound better for music and larger drivers aren't as fast or quick as smaller ones. Just to put the icing on the cake all PSA subs use the ICE amp modules with precise DSP'd controlled front ends. Take one out for a test drive and I'll bet you never go back to the big box stores again having to deal with flapping noise boxes again.
Nothing against servo subs but if you like them so much why wouldn't you just upgrade to another or duals since you seemed to have acquired a taste for their sound, just curious, I can't comment on Rythmik or Velodyn as I've never heard either one but I can share my experience with almost every PSA sub out there and ones that will be out there.
I hope I didn't come off too strong here but when you said you fear that a PSA sub would sound like the flapping noise boxes, that just ruffled my feathers a bit..................No, my last name is not Farina or Vodhanel...........
