First of all, hello peeps. Been lurking here a long while.
1) 1.45 ft³ sealed enclosure, .75" MDF.
2) 350-400 watts of clean sub power available at 2ohm, ~175-200w at 4ohm
3) current sub MTX TR5512-44 (weak link?), low pass at ~65hz-70hz 24db, 15hz-25hz subsonic.
4) HAT I61-2v2 mids on mdf baffles, 135w x 2, highpassed at 85hz 12db, doors matted and sealed (I am really loving these babies).
I basically want to try a new sub to go along with my new HAT Imagine 6.5". I want more SQ and deeper response, so should I go for a lower Fs and higher sensitivity subwoofer as compared top my current MTX? I am not into slamming the poor sub to death anymore, I want clear, clean bass, but with the ability to crank it up occasionally. I am also after better transient response, assuming I need a stronger motor as per the T/S parameters? I listen to alot of high quality electronica such as Electric Universe, Astrix, Bluetech, Delerium, shpongle, vocal psytrance, etc., with forays into southern rap and an occasional whatever else, Pink Floyd, SRV, Tool, ad infinitum.
I cannot change enclosure size due to it being recessed and made into the spare tire well of my 2009 Pontiac G8 GT, except for stuffing it a bit with wood to cut airspace. Sealed is an absolute as well since I am after SQ and ease of install. I am just really getting into tuning for SQ and loving it, getting the phase correct on all speakers, crossover points, etc., now I want a better subwoofer. IS there a noticeable difference by changing to a "better" sub, considering I have it very well matched to my mids right now? IS there a large enough gain in SQ to justify spending 200-300 bucks on a new sub?
