Current Inexpensive sub that can get it done cheap

I have two listening areas at my house. I have a full[on home theatre out in my barn, That set-up staets with a krell HTS (currently in the shop blowing fuses), Rotel for power 2 x 200wpc for the fronts. And a 6 channel rotel running bridged for the middle and rears at 150wpc for them. I also have an older Def Tech PF15tl sub. By the way the fronts are b and w's 604s3's, rears are def tech bipolars, and a nice paradigm center.

I have a 2 channel I want to enjoy in the house. I have some nice BW cdm7 speakers. Right now its a small yammie receiver... buts its gonna go soon. What kind of sub would pound my living room with as much snappy bass as it can handle. I like rock music and it gets played as loud as it still sounds good! If any knows a fairly affordable sub that is worth investing in please let me know!

Depending on your definition of cheap, check out partsexpress dot com and look at the Dayton sub kits. From my understanding the sound decent and can really pound it out for the low cost they are asking.

The new REL sub is less than $800 retail. Small little thing. I think it's a small T Series?

Be cautious when buying inexpensive subs as they tend to produce more distortion and the distorted 1st and 2nd order harmonics can compromise midrange sound quality

If your main speakers are ported look for a ported sub, if your mains are sealed look for a sealed box sub ... if your main speakers have steep 4th order crossover slopes look for a sub with steep 24db crossover slopes, if your main speakers have 1st order crossovers you need to look for a sub that will work with that gentler first order slope ... all this will make blending sub with mains easier

More important than the name on the box is correct room placement ... setting of crossover point ... set it to high and the sub will sound slow and muddy ... try setting crossover 1 octave above main speakers -3db point and then equalize volume of sub to match main speakers

If your looking for slam stick with a 12 incher and don't worry about the room being to small as the wave must go back and forth to complete one cycle ... so a 15 foot room could handle a 30 foot wave or 28hz note

Find a sub with low distortion specs that has similar build characteristics to your main speakers and let the shopping in your price range begin

Now can someone please explain to me why I need 3000 watts to drive a sub to 121 db @25hzs when my mains speakers play at 90 db ... TIA

Madisound has either a 10" or 12" powered subwoofer at a reasonable price. Check their website. Highly recommended.

Thanks to all who replied so far! I did fail to define my use of "inexpensive" as was pointed out. I would say suggestions in the $1000 and less would be in my range.
This sub will be used for 2 channel music only, with the cdm7's. My room is 24 x 12 with 8 foot ceiling.
