    proper midbass from a DIY 2 way?

    here's what i have right now.

    alpine 9887

    crossfire vr602 (150x2 @ 4 ohm, 12v) running a pair of alumapro alc components

    kicker kx2500.1 running a ported dd 9518g

    us acoustics usa4050 (4x50 @ 4 ohms, underrated)



    my alumapros are mounted in the door, 6.5 inch driver, wouldnt be difficult to fit a 7 inch in the same spot, 8 might be pushing it. the tweets are mounted high in the door.

    my options are
    a. keep the same location, buy a really nice DIY 2 way set, use my crossfire for the mids and usa for the tweets.
    b. do a set of a custom kicks for a 4-5 inch mid and tweet, use the door for dedicated midbass. obviously more time, effort and money.

    are there any high end mid drivers that might fit the bill given that ~175x2 @ 4 ohms from my crossfire? enough midbass to keep up with my 18 and still blend nicely with the tweet is what i'm after.

    Re: proper midbass from a DIY 2 way?

    looking at pairing these dayton tweets
    http://www.partsexpress.com/pe/pshow...75-130&scqty=2

    with these mids
    http://www.creativesound.ca/details.php?model=SDX7

    how does that look, with about a 1.8k crossover point?

    Do B...as you increase driver size you decrease the frequency at which a driver starts to beam (AKA where the response begins rolling off when mounted off axis). I wouldn't run an 8 inch midrange unless I had a stout tweeter that I could crossover at 2khz or below...

    Plus a ton more I never added, lol. If you are not on the list and you had a pleasant transaction with me, PM me!!!

    Re: proper midbass from a DIY 2 way?

    the driver i'm looking at is an xbl^2 driver, updated version of the extremis basically, supposed to be better in everyway and work well for dedicated midbass or 2 ways with low crossed tweets. the tweets are said to be ok down to 1.5, i'm planning to cross at 1.8-2k, 100w rms so bridging the zed amp to the tweets, using the crossfire for the sdx7s.

    i think it will be a nice compromise, saving the expense of doing custom kicks now, but still should sound nice, and the driver will integrate well into a 3 way if i go that route later.

    That sounds like a good plan then...I say go for it, looks like you are starting with good drivers. Just be careful with the tweeter You can always rip it out and do 3 way later...

    Re: proper midbass from a DIY 2 way?

    the tweeter is gonna take some working to get in there, its so much bigger than what i have now. probably going to glass it, but i've never done it before.

    Just take your time with fiberglassing, rushing will only lead to imperfections and frustration...

    Re: proper midbass from a DIY 2 way?

    yeah but i'm not a very patient person, and i could see myself rushing and f#cking it all up. what would a small fiberglass job like that run at a shop, 200ish?

    ran into a bit of a snag with ordering everything. the sd7's are 100w rms, i'd like to have 2-300 for headroom, but they're only available in 8 ohm drivers. i can get an underrated 150x2 @ 4 ohms from my usa4050 if i bridge it, and maybe have 175-200 for it. so i'm going to wait until i get paid end of next week, think about my options. i got a little excited this weekend, picked up that amp, the dayton tweets, and about 200 dollars worth of supplies for cleaning up my install a bit and splitting power since i'm running 2 amps for my highs.

    need to pull my doors apart this weekend and check my depth and clearance too, these drivers are almost an inch and 1/4 deeper than my alumapros.
