    Hehe, I thank my parents for it lol. Sitting my final exams in three days, then work begins (popping over to the UK to collect the stuff). Getting a LinITX screen (originally made by C4, UK Lilliput, only more reliable) and a few more bits.
    I was thinking, if I don't bother getting any alloys (16" at the mo), then I have another $1000 to spend on system...reckon I should ;~) ?

    Still undecided on the size
    I wonder honestly if there'll be much difference in the SPL

    depends on the subwoofer. naturally extra cone area will give you an advantage, but efficieny comes into play too. for example, the old xbl2 technology (XXX) was FAR more efficient with the larger cone drivers. Thus, the 10 wasnt loud without a ridiculous amount of power to it. VERY ridiculous. the 15 was 5 dB more efficient than the 12! more than cone area made up for that huge difference!

    but more importantly, we have to consider what frequencies you want to listen to. that 15 may be wya more efficient, but if you want 100 Hz real loud for bass guitar, that 15XXX probbaly isnt the way to go, as it will not really be designed to play that loud. not really....

    finally, the last wrench to throw in the works will be that the human ear hears different frequencies at a different volume, compared to a sound meter. so you might be able to set off car alarms at 30 Hz, but take it to competition and play those same tones and you wont break 130 dB . meanwhile you wonder where that same incredible bass response is at 70 Hz, and post numbers 10 dB up!

    In the end, I would base your decision on the music you listen to versus how loud you want to be versus your audio goals. the three will come together to zero in on the right subwoofer for the right job!

    Lol true. I listen to alot of easy listening - Tool, Pearl Jam, etc. Some dance and rap too - so 30Hz gotta be achievable! I think the 15" in a snailshell. Or a sealed 12

    for your "alot" music, I'd focus on your 6.5's up front, getting 70 Hz and up all perfect and how you like.

    for your rap and dance, id stay sealed. I'd use powerhandling and excursion to get the volume you want rather than box alignments. 12's or 15's, if you are sticking with RE. any RE subwoofer 12 or 15 I think will get you where you want. your subwoofer will do the least duty of all yoru speakers, though, for pearl jam, tool, etc.

    with 1200 rms I think you should be good for the gamut of subwoofers, as well. SE leaves a question in my mind, as far as too much power. I'm not sure if they can take the power for daily driving. Knowing RE though, they can, easily. I'd still confirm. I know the others definitely can.

    if it were my personal choice, matching the stuff I have now, I would probably be going for an SE 15 sealed. however, if you dont expect your stage speakers to get very very low, the 12 might be in order. You'll have ot judge for yourself, though.

    I may wire it series/parallel, sealed 15", so the JBL throws about 750W at it.
    What fronts? Was thinking the Rainbow SLC 230 Kickbasses in door pods.
    you got Messenger?

    I have AIM whiterabbitttttt, but not messenger. I've never heard any rainbow speakers below rainbow pro's, so Im not sure of the midbass capabilities of your proposed speakers, though.

    another thing to keep in mind is what kind of audio goals you have. some people choose to eliminate all distortion, otherwise they dont care. the subwoofers sound ten times louder than the tweeters, instrumentation is all over the place, there are four component sets dispersed through the car, but its loud as hell and no distortion. Other's want all their sound in front of them, and spend large amounts of time and money getting equipment stuffed in front of the drivers seat that extends as low as possible, saving only the lowest frequencies for behind the seats. so that will affect your choice as well.

    if you want your bass guitar in front of you, then a 15 might be better afterall, save the subbass for the lowest frequencies, not have upperbass to draw the stage back.

    if you dont care, and just want loud bass guitar, you might even go up to a 10" subwoofer, feed it lots of power, turn the crossover high, and have a rockin' bass guitar, but itll be behind you.

    isnt it funny how such a simple question can get SO complicated?

Nakamichi amp for comps is a major yes?
    And what sound card?


    L

    running a set of 12w6v2s in my GTi right now....IMO they sound fine, though some people on here will say different

    I've also run the same rainbows before (switched to focal though), they are good speakers, no doubt, I just liked the warmth from the focals better.

    Naki is good stuff as well, no doubt.

    As for a sound card, it all depends on how you want the signal to be transmitted? I'm using hte PCMCIA SB card for it's optic out to the Alpine PXA-H701 processor....then into my Arc amps....

    if you are looking for SQ, don't even worry about SPL honnestly....I hit a 141 db with those 2 - 12s in a sealed box, by dvd-rom/cd-rom kept skipping, so I need to get a USB external that I can just hold in my hand while running through the SPL lane. I out score everyone is SQ by like 5-10db every time....it's WAY over kill....so I wouldn't worry too much about not having enough bass.

    Ask whiterabbit mentioned, you need to focus more on the front stage. I'm running the K2Ps from Focal, which have AMAZING mid bass response....so much so that I have to run the subs WAY low and turned WAY down so I don't have too much bass....the big kettle drums sound amazing when listening to the SQ cd for USACi, I have; had quite a few judges with wide eyes look over to me when hearing those drums....they were amazed at how well the K2Ps reproduced the sounds...

    apparently it's still good enough to take home another first place as well as a best of show this weekend at a tripple point event in houston....I even beat out someone in a class above me (pro) for best of show....=]

    you mentioned competition...are you going to be competing? or do you already? if so, what sanctioning body? SLAP/IASCA/USAci? and what class?

    a 2.1 sound card would uncomplicate things no end
