  1. basing your decision on just xmax and sensitivity doesn't really work...

    from what i've seen the sensitivity rating is more or less useless.

    also different ways to rate xmax. seems like a lot of companies list it at 70% bl, but not all of them.

    i'd go with power handling if you're just looking at those 3 specs. i could be wrong but as long as you can control excursion so bl doesn't drop off you don't have to worry about xmax too much...

  2. i've had one part of my 21st birthday planned out since i was like 17. I'm gonna do a body shot off of some hot chica on the hood of my car, while Ray J's "Sexy Can I" is playing and my subs are beating away.

    Needless to say i can't wait :)

    or you can use my subs :P

    my 21st = 21 shots, more of my friends idea than mine though. needless to say it wasn't too great of a night. been going to bars since i was 17, no age crap in china :) so it actually being legal to buy here wasn't a big deal. plus i have an older brother = fake id. i mean all azns look alike anyways so its easy to get away with ;)

  3. why are you inverting them? looks? being able to smell the coils? i remember someone said they had done testing and found that normal mounting was always louder. i think it ends up looking cleaner as well, no wiring visible.

    recently reread this (info at the bottom)

    important quote:

    I get how Oki's designs work, and agree with him you shouldn't base the end resultant upon 1 driver x then number you have. Its simple when you think about it, the rear chambers are heavily damped from being fairly compact but you build up a great amount of control and reduce the overall Xmax. Your in a sense restraining the excursion. However, the front waves are therefore much more powerful, couple that with a chamber with a decent set of rads for a desired bandwidth and you get a killer setup.

    The 4th orders i've heard tend to loose out on output when using larger sealed cabs, your reducing the compression with a larger chamber and defeating the object of the effects of 'bandpass' on the suspenion of the driver. Large rear cabs and semi large front makes for just a muddy undefined sound, also at a cost of output.

    Its fair to say Oki's systems show exactly why a bandpass need not depend on the F3 of the driver.

    theres more in there though. go read it lol.

    makes me wonder about the 2 cubes rear.

    need an expert in here lol

  4. who recommends??

    you'll have zero midbass for what you picked for you 6w4ps. also keep in mind with that you're going to have your mids playing all the way up to tweeter range. it'll work, just don't think it'll sound the best.

    so basically you'll want your mids playing something from 80 to somewhere like 4-5khz then your tweets will pick up everything above that.

    i haven't used either of those so i don't know what they like. need people who know those to chime in. also i'm not big into sq, just know the basics of setting this up so hopefuly someone who knows shit will say something.

  5. that amp will work. just go out and buy some passive crossovers/bass blockers. just find out where you want it crossed and at what slope. so like 3khz 24db/octave (not actually sure what those tweets like but that's just a generalized example) crescendo sells em for their tweets. parts express has em. i think stinger has em too. plenty of places. all fairly cheap.

  6. you're making your supertweeters play from 100hz and up...

    yea that's a problem. lol. turn it down and get your stuff crossed over properly.

    generally you want to leave your bass setting at flat on your eq.

    *edit - hatersgonnahate. his amp is crossed at 100 hz... those seleniums don't have built in passive crossovers. guessing that's what's saving your tweeters.
