What sub under a grand?


Looking to replace my rel t1 which is having problems. My current setup is Parasound a21 amp and the Parasound p5 pre amp,Marantz sr 5007 avr and the Marantz sa8001 sacd. Main speakers Vienna Acoustics Mozart grand. 70% is for music and 30% movies, gaming and tv.

"Fast response" from woofers is another example of audio nonsense...all woofers get the signal at the same time as the main speakers, there is no significant measurable delay related to cone material, magnets, or woofer amps, and there is pretty much no reason to put subs into the lower midrange unless your main speakers are very limited in range...tiny...really tiny.
Wolfie is telling his bullshit again. When you compare
subwoofers in timing and speed there are clear differences.
The subwoofers with a faster response, better amps and better
magnets can be used to a much higher freq. response against
those who are slower and are less controlled.

Wolfie is using a more than 10 years old Rel Q150 subwoofer.
When it came out, It was a very nice subwoofer. I sold a lot
of them. ( I prefer closed subwoofers with frontfiring) But we
are now living in 2014. The quality has changed a lot. There
are now different rules and possibilities compared to the
past.
A subs job is to go BOOM! right? iv'e only owned 2 subs the rel and a b&w, and with the b&w sub I never noticed any lag. In fact I had it in a spot that was outta sight and others would compliment my main speakers on having such good bass response, they didn't know I had a sub in the mix. as long as i'm running low pass and start at 80hz threw my pre amp I think it'll blend in just fine.
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?
