    Re: Another buyout that really makes me wish PE still...

    I think their specs are very consistent, thanks Mark

    Thanks . I 'm in the process of setting up my own measuring rig. I will be using a M-Audio Fast Track MKII USB sound card with the Dayton mic. With a usb sound card I can use my laptop or any other computer I chose. What type of setup are you using? I forgot when measuring speakers in a box baffle step compensation isn't necessary. Is it better to measure speakers in their boxes rather then on an infinite baffle?

    7ft to side wall, 4ft from back wall.

    Forgot to note on chart that I did not apply any smoothing to the curves.

    Measured the other 3 drivers tonight. It's about 10 degrees colder in the house than it was when I measured #1 Sunday. Also, drove #1 for about an hour with music. The other three I just stretched the suspension and measured. None are really broken-in.


    --------#1------#2-----#3-----#4
    re ---- 3.391 - 3.425 - 3.358 - 3.229
    fs ---- 67.29 - 70.66 - 72.67 - 73.35
    Qt --- 0.4477 - 0.4498 - 0.4551 - 0.4505
    Qe --- 0.5901 - 0.6096 - 0.6245 - 0.6101
    Qm -- 1.8560 - 1.7150 - 1.6780 - 1.7210
    Le --- 0.5555 - 0.5502 - 0.5502 - 0.5389
    Mms - 7.317 - 6.869 - 6.570 - 6.686
    Vas -- 7.058 - 6.817 - 6.739 - 6.500

    I have Audax to sell

    I have a pair of the HP130ZO and a pair of the AP130ZO if anyone prefers the Aerogel cones over the paper. $5.00 each

    Please excuse the thread hi-jack.

    Wow, look nice for only 6.50 per driver!

    How about pairing them up with the Vifa DQ25SC16 crossed somewhere in the 2750-3000 range?

    That 4 Ohm impedance does make the mtm idea more difficult.

    So how much fidelity IS the MAX amount of fidelity, anyway?

    Mark, do you mind to do WT3 sweep on a different driver for consistency? Also a distortion plot would be great

    Well, I got five on the way, so to top out my $100 tog et free shipping I remembered some cables, a mixer, a microphone...

    Guess I'll be measuring soon.

    They look very nice for the money, and shouldn't have any problems crossing over in the 2.5-3k range.

    Doesn't look like much to complain about there, especially for under $7.00.

    OX is 2x the price of the BCS and almost 4x the price of the woofer:eek: Not gonna happen for this possible project.

    I'm gonna snag a few of those since I have a couple friends wanting cheap builds. I'll probably just do small MT's with some Tang Band tweeters I've had for awhile.

    That new Peerless India waveguide/tweeter buyout combo looks fun to play with too.
