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???

martin logan dynamo is a really fast, tight sub which should pair well with the maggies--very good value used.
Hey Shcmitty1 I have my 1.7i's for 4 years and have worked on various ways to improve bass with most of the suggestions posted here. The problem is the Maggie's produce such a clean it's hard to integrated a sub without smearing the existing sounds. My last addition is a 1000 want parasound 21+ and a slight increase in volume. They are so power hungry and sing when feed. I would like to hear from more Maggie owner being this was the question you posed. Thanks
Tight bass can be created by a bass player damping every note, and utilizing over-damped drums. Listen to this sort of thing outside with no acoustic boundaries and there ya go!
I've been playing bass since 6th grade. True- it gets a lot more percussive played that way. But impact is one thing- tight bass is another. If the bass is right, its got impact **and** definition. If its tight bass, its got punch but the impact is insufficient and no definition- you keep trying to turn it up to get it to satisfy. Now I might be harder to satisfy because I've played bass so long; in my band right now I play keyboards and keys are more capable of making unnatural bass notes, but even there, the sound is usually a combination of what the player hears in tandem with whatever speaker he uses to play the keys with. But if I'm playing in a club, even when playing such bass, its anything but 'tight'. The speakers are interacting with the room...
I have extensively demo'ed the JL Audio D108 sealed sub and it is extremely tight and musical.  The 8" driver is fast and agile with no bloat or boom.  Covers the upper sub-bass quite well, better than larger diameter subwoofers.  Depending on room size (1) would be fine, (2) better.  
You sacrifice some of the deepest frequency theatrics but gain some upper bass punch and integration- sounds exactly like your goals.
