Tight bass sub recommendations


What are the recommendations for a high quality subwoofer set- up. I have Maggie’s 1.7I speakers which I love but I think could use a little sub energy. Most of what I have tested seems a little boomy. I know there are 2 schools of thought 1 sub or 2 subs. I’m just looking for a deep Tight bass. Thoughts???

I've accompanied both electric and acoustic basses (with and without a pickup going to an amp), and reproducing an acoustic is a more demanding task that reproducing an electric. Most speakers and subs---and most importantly, rooms!, to one degree or another, add a little "plumpness" to the sound of an acoustic. An upright bass, played purely acoustically, sounds more like a cello than an electric bass, just playing lower notes. I got to intimately know the sound of a cello from my sister practicing hers at home.

Some of my favorite electric bassists play sometimes using the heel of their right hand (if right-handed) to mute the string, in effect making the electric bass sound more like an acoustic. Listen to Joey Spampinato of NRBQ to hear what I'm talking about. Keith Richards loves his playing, enlisting him for the band he put together for his Chuck Berry documentary, and offering him the bassist slot in The Stones when Bill Wyman left. Joey turned down the offer, electing to remain with NRBQ, a much better band.

If the sub can't correct for the room then you will have plumpyier bass and it will not sound as if its coming from the main speakers.  Which should be the altimate goal.   
As for Rel good subs but not necessarily a sonic match to every speaker and room.  
+1 for Rythmik

Owned various REL, Velodyne, ML, Revel, SVS, Infinity, B&W, Wharfdale, Sunfire, plus others I don't care to remember...  an MBL too....   Only Wilson impress more but doesn't like that price tag.  I like JL too but matching it seamlessly is very hard.
