What sub under a grand?

Speakers and subs can function and sound differently of course, but "timing" and "speed" are useless terms often used by technically challenged gasbags like Bo, who seems to lack the ability or actual knowledge to explain himself. I'm not sure what Bo means by his use of the term "speed" in the context of subs having a "higher frequency response", and I seriously doubt anybody else understands him either...subs shouldn't generally be required to produce a midrange frequency response as that can lead to phase and other issues (and generally sounds like crap), and is absolutely not necessary in the real world to reproduce musical low frequencies to blend with most "main" speakers...My little REL works perfectly reproducing the frequencies I require of it (when it doesn't I'll replace it), happens to be as technically modern as pretty much anything new (according to what I've heard from newer designs in various systems as well as in shops like nearby Goodwin's, as well as comments from some of their sales dudes who do have some expertise from years of selling sophisticated gear), and all sorts of "paper" cone drivers are utilized in newer speaker designs that sound fabulous, although perhaps not in Bo's seriously narrow little world.

I should have the psa sub today,and i'm sure it'll give me what I need "speed, timing" and everything in between.I think for ht it'll give me that thunder i'm looking for, and that punch i'm looking for in music to make it sound live and alive.tell you what I think this pm wolf, though it may take a few days to get it set up. and of course so called breakin?

Jughead, subs do a lot more than just go boom. Really good subs can be crossed over very high as long as they are integrated well. They can add unbelievable stage depth and realism. Gun shots in movies can have a startling effect and really fill the room. The timing of the high passed sub relative to the front mains is critical. So moving subs around the room,setting delays, eq,s, room correction all have a huge impact on frequency in the room which will in effect have a big impact on imaging. Bone crushing bass can start as high as 200hz and it's obvious Bo has played with these higher frequencies and room correction.
The other thing a good sub can do which is very important is take the load off your amp. 80hz is still a good load for most amps and speakers. IMO, sealed subs are the way to go.

The psa is a sealed down fire sub, and I understand a sub does more than go boom. imaging and thunderous bass is what I said I was looking for all along,and so far the psa has delivered. I'm plugged into my p5's low pass at 80hz and the explosions and gunfire from the ps4 while playing cod advanced warfare is unreal! I have 29 more day's in home trial to really get to know it and hear what music is like.so far I listened to 1 cd avenged sevenfolds heil to the king and the sub blended in well with my main speakers.

all still sounds good with the psa music has depth and nice punch and ht duty is where it really shines, it's driving my wife nuts she say's it sounds like a war zone upstairs! I don't think I have it placed in the right spot yet still trying to find that sweet spot. But for 750 delivered and being brand new I don't think you can beat it svs sb 2000 maybe? The only think I don't like about the psa is it's size it's a beast! but that's the only problem I find can find with it.
