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.

The idea's to use it higher than 80hz came from Audyssey. To be honest I never went higher than 80hz. So it was complete new for me. I thought it would not make a big difference. But I was wrong. The overall sound became more involving, stage depth became even bigger. Sharper individual focus of instruments and voices. I started at 120 hz, at the end I stopped at 140hz. The thing what is important that you need subwoofers with a fast response. This depends about the material use of a manufacturer. And also the magnet is important for the control as the amp which is used.

These days I set most subwoofers till 120hz of my clients. Audio always will be about quality and comparing. When I would have followed all rules in audio I would never be were I am now.Looking for a higher endresult in sound time and testing is needed.

Low freq. are very easy to be explained why they have such a big influence. When the freq. goes deeper, there will be more emotion. It is that simple. Ofcourse a concert without a deep low freq. is useless!
And I think the psa can do this and not break a sweat, the rel t1 can't. the rel blends well with the main speakers because I have everything set so low you can't feel or hear it anyway.You have to keep in mind one of the founders of psa was the v in svs, I think they know how to build a sub that's not only fast and responsive and that you can feel,the rel t1 falls short. now if I spent 3k on a rel I think i'd get fast deep bass. I'm good spending 750 shipped I think there's no way i'll be disappointed in this sub. and their customer support is outstanding! rels customer support sucks! I ran into the same thing when buying an amp, mccormack, krell, mcintosh, so on and so on. I ended up with Parasound a21 and i'm sure it's not as fast and controlled as the other amps and whatever audiophile jargon you want to throw at it and measurements you can't hear or see but know it's there.in other words i'm fine with my amp and i'll be fine with the psa.
"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.
