    4 American Bass xd 6.5 subs 4th order or T Line

    I was looking at the DD 6.5 subs first, but saw these and think they might work as well but are cheaper. Pulled the specs from their site and will power them with an old Rockford 800a2, so a clean 800 rms 4ohm. Each sub will see 200 watts at 4 ohms which also works better for my amp.

    impedence (ohm) 4
    power (rms) 150
    power (peak) 300
    vc (inch) 1.5A/4
    magnet (oz) 60
    dcr (ohM) 3.2
    L (mh) 2.288
    fs (hz) 48.8
    sd (msqM) 12.27
    bl 10.74
    qms 4.334
    qes 0.438
    qts 0.397
    n (%) 0.113
    SPLo (dB) 82.6
    vas (L) 4.423
    Cms (mmm/N) 206.84
    Mms (G) 51.5
    Mmd (G) 50.7
    Xmax (mm) 8
    MD (mm) 105
    OD (mm) 166.5
    OH (mm) 122
    MD (mm) 105

    I was orginally thinking a 4th order at 1 cube common sealed and 1.5 ported at 50hz. I hadnt figured out port area, but want it to more musical so would be smaller. I also kicked around the idea of a T line. I dont car about metering or SPL. Looking for decent thump from 70 down in a Pathfinder Hatch. I also want to get as much low end out of the set up as possible thats why the thought of a T line.

    What do you guys think?

    Guessing at bp and TL type designs is not the best way to get a good enclosure. Any reason you want to use tiny subs in a big box?



    HU - Pioneer
    Front Stage - Old school MB Quartz run off a JL e2150
    Rear Stage - Stock - well one works, LOL
    Sub - Tang Band 740C in between the front seats
    Sub Amp - A tiny Kenwood. - because it fits under the seat.
    Total Spent on everything $50.

    To be honest, just because. I have a bandpass T line for a 1508 and it sounds incredible. Im really trying to figure out how the guy did the design so I can do on 4 small subs. I have seen several guys using 4 8's and multiple 6's and they love them so I figured why not try.

    I have to play with the series/parrallel wiring, but if I end up at 2 ohms Im ok. Ive run the amp there before, but cant go lower than that. I thought with series/parrallel wiring, you could get 4 4ohms driver to a 4 ohm mono load?
