need to find subs with lots of slam for HT

hi all, i have a small theater room. it is 12x14 with an 8 foot ceiling. i currently have 2 velodyne cht-10 (10 inch $650 each) subs. i use a svs pb 13 ultra set in 10hz mode to handle the super low frequencies that the velo's cant. i set the svs's x-over as low as possible. it shakes the room which i love, but... only from about 30 hz and below. i want to leave the svs as it is because if i allow the svs to accept higher frequencies while tuned to 10hz, the bass becomes sloppy at the higher frequencies. i have a integra dhc 80.1 with audyssey which calibrates all my subs.

i have not tried different subs in my theater room. many years ago i tried a dahlquist 12" ($900 sub) and i remember i could feel the bass more. i'm sure it had a bit better low freq. extension but maybe it was just more powerful? moves more air? 12 inch perhaps? i dont know how all these factors come into play when choosing a subwoofer. i got rid of that sub and got the 2 velo's mentioned above. there doesnt seem to be as much slam from the velo's. are they too low end i wonder? now i want that HT chest slam, as i have upgaded pretty much all my equipment but still have those velo's.

so this is where i am confused. i want the tightest bass with possible with alot of chest caving slam. i dont know if a couple of small 8 inch(say sunfire super juniors for example) would give me the result i'm looking for due to its small woofer size. i'm not necessarily looking for low frequecy extension because my svs handles that.

do i need to get into the 12 or 15 inch subs for the slam? possibly super highend 10 inch like the jl fathom f110. i dont want big if they produce flabby/sluggish bass. i should mention that i have bass traps in my room as well.

however, my room is 12x14 with an 8 foot ceiling so i dont want to throw money away on subs that would be overkill. i definately dont want bass overhang (sloppy bass) that some big subs may produce in small rooms.

can anyone suggest what subwoofers (model and size) i would need to achieve alot of clean bass with alot of HT slam for my small room?
i dont necessarily need the most exspensive...i just want to be happy with tight clean bass and enjoy the punches on my chest!!!

thanks and much appreciated,
cheers

The trouble with cheaper subs is that they either use a small driver (for tightness), or large driver (for depth), but don't give you both. I don't think adding subs fixes the problem.

I also have a small room (13x15) and use a Velodyne Optimum 8. It gives me all I need, but admit it won't rattle the windows.

I suspect you need a high powered sub with at least a 12 inch driver. The SVS ultra should do the job, but I guess you feel it doesn't.

You can look at the Velodyne Optimum 12 , the DD series or the JL audio Fathom 110. They should all do the job.

thanks guys for your response. here is exactly what i am doing. i set the svs at 40hz (lowest) with the x-over on the back. i run the audyssey with all 3 subs. the bass is ok but i feel its alot better after i tweak it. heres how:
i use the eq on the back of the svs. i lower the 30-40 hz range as much as the eq allows me to. then turn it up about 8-10 db's. the result is awesome. the whole room shakes and i feel the hits right on my body. this may not be correct but it is very cool when each punch and effect literally shakes you. i know that my velo's are the weak link, therefore i want to find subs that produce excellent slam in the higher frequencies that my svs does not get. not sure what i need tho...8/10/12/15 inch, which models etc for my size room.

i've tried running just the svs in sealed and its good but no where near the super low frequency boost that im looking for. in sealed mode (svs) if i turn up the sub level, all the frequencies up to 80hz get boosted...which sounds terrible bass overkill.
its like you said bob, you get one or the other high bass or low bass from the woofers but not both. i am trying to get both with multiple subs. i just need some advice on how to acheive it.

your thoughts or suggestions?
thanks,
cheers
