nht vs cerwin vega

look the cerwin vega is designed for boom and sizzle. I don't think that's what you want if you are listening to nht.
subs can eat power. not ucommon to find audiophile woofer amps at 300-600 watts. ou should not hear subs. Bass is non-directional.so yuo should not "hear" subs.

Are you running a passive sub or are you talking about the 8" woofers in the 2.5i? What part of the volume are you unhappy with, bass or overall?

bass is not the problem with nhts. in the small room they are located, almost too much bass. too close to corners and back wall, ill live with it. i do know when you hear loud subs what u hear is distortion. its the mid-highs that seem "not as loud". do i just need to throw more watts at them to get the high spl? they are rated to 200 watts max, does that mean use 400?

100 watts is to the 8 in subs in the 2.5i. would probbly sound better with twice that. amp is carver tfm15. used sub output for the signal. im not shure if that is correct. i do have a klipsch ksw12 cut off above 70 hz. mainly for movies.

If you are using the sub output to feed the 8-inchers, then you are only givng them signal below the sub xover (maybe 80hz), when their internal crossover is probably designed at more like 250 Hz. Your lower mids and upper bass are probably non-existent. That would certainly keep it from 'getting loud' ;-)

Feed both sets of binding posts a full-range signal, or just jumper them and use one good 150-200 wpc stereo amp, and you'll be fine.
