Subwoofer info


After what seems like a hundred hours or more of reading.  I think I am at the end of my search for subs.  If anyone has listened to any of these subs, I would greatly appreciate your review on them.  After all this research I have narrowed it down to 3 subs, I dont really care about any other subs, probably due to this 2 months of research. Exhaustion has set in and a choice needs to be made.  I have only had the chance to listen to a few, best buy being my source for listening. I did listen to Martin,  rel,  svs sb 2000 and sb 4000. Rel and Martin's under 1k, did not give me toe tapping. Both svs's did. (I will be selling both my vanderstien 2wq, i havent listened to them in yrs and just want new toys)  Other than BB, I have to travel quite far for hi end.  I listen to 60/40 music/HT.  My room is 8'x14'x24'.  Front spkrs are totem winds. I will be purchasing one in February and a second with 6 months.  In order these are my choices.
1.  Svs sb 3000. 
2.  Rymthik f12se.  
3.  Paradigm defiance x12

I've read alot on svs and rymthik, can't find much on x12.  Worried about rymthik only having 370 amp, yes I know it's servo. But svs is 800/2500. Quite a difference.  I thought about 15 inch sub, but the weight is crazy.  Ported is also heavy and possibly not up to my standards for tight music.  So I guess my question is,  who has listened to these 3 subs and what is your experience and evaluation of these subs. Details are appreciated.  Thanks, Pete

Rythmik is more bang for buck than JL Audio, their $1800 sub measures similarly to their $2500 one. 
 
Rythmik gives a slight multi-sub discount. Rythmik’s warrenty is also much better than JL Audio, 3 years vs 1 year for the amp and 5 years vs 2 years for the drivers.
I do appreciate all the info. I am sure JL  is great, I just don't want to spend JL money.  After lots serious consideration,  I realize I dont want 100 lb subs. This is why I am looking at 12" subs. Trust me I struggled with it, until I was at best buy and went over to lift a svs sb 4k and said nope. Went over to the sb 2k and thought wow so much nicer. This is one reason why I am getting rid of my vanderstien 2wsq , down sizing for the future.  Back in the day it was fine. I will be using the sub out on my dc1 and within 6 months get an avm 720 or the 60, not sure which one yet. Then purchase second sub. 
Thanks mzk,  
I will probably call rymthik when I get back from vaka.  See what they offer for trial basis. If all goes well I hope to listen to all 3 at the same time.  Paradigm, svs and rymthik.  No sure about JL. All have to meet my budget of 2 subs. Between 2k and 2500. I will rate on price, weight, warranty,  customer service  and sound. Apparently,  no svs owners are replying to this thread.  Thanks everyone,  I will continue look back and see if anymore recommendations.
