    Default Peerless Genelec Buyout FR and Notes

    Folks:

    If you bought these and used them as car or home subs, I would strongly suggest using them for a 3 way speaker. They sound real nice and have a lot of oomph. Here is the FR Plot (sealed, 2.3CF, 13.5" baffle). Note that the bit of roll-off shows due to the nearfield + farfield MLS merge and they are quite strong in room but not overpowering

    Actual sensitivity is around 88dB at 1Khz.



    Here are a couple "starter" XO's for anyone sitting on these.

    "Relaxed" BW3 at 300-350Hz (used in Metropolis Project at CKDIY) - by relaxed I mean they are app. 15-17dB/octave, this seemed to sound better.



    And the BW3 schematic:




    LR2 at 350Hz (played with a bit)



    And the LR2 schematic:



    Basically, you can do a lot with these and they are likely good to near 1Khz, allowing use of a dome mid and a higher XO freq as well.

    Here are the TS Parameters for the 4 Ed and I have:

    Stamped frame reminds me of the larger SB frames in shape. No vent in pole piece, inverted dustcap vented through teardrop-shaped cutouts in the cone to above spider. Below are averages of 4 drivers.

    AVG RE: 6.58 OHMS
    AVG FS: 29.72 HZ
    AVG QE: 0.65
    AVG QM: 3.89
    AVG QT: 0.56
    AVG ZMAX (FS): 46.03 OHMS
    AVG LE: 0.96 MH
    AVG VAS: 104.5 L
    CONE DIA: 8.25" (CONE + HALF OF SURROUND)
    SD: 345 CM2
    AVG BL: 9.35
    AVG MMS: 46.05 GR
    AVG SENS: 88.1 DB
    AVG % EFF: .408%
    XMAX: 8mm (by spec.)

    Notes:
    Fs ran from 28.55Hz - 31.8Hz
    Vas ran from 92.66 L - 110.45 L
    Qts ran from 0.53 - 0.61
    Higher Qts - lower Vas as is normal with samples, etc.

    I like the LR2 option, especially if the woofer is a clean performer. That alignment eases up the midrange duties as it takes care of the baffle step loss suffered by the mid.

    Looking forward to hearing the Metropolis in April.

    Cr*p! I wish I'd bought a case or 2 of them! Very comparable to the Peerless 10 in Paul's Tarkus, but at 36.00 each when you buy 4+, seriously nice in price. PE: GET MORE!!!

    Cheers / Robert

    That graph looks a lot like mine of the same:

    I bought four of them.

    I'm using them in my first dipole experiment, 2 per side. I measured one pair individually, then overlayed the measurements. Looks like the same driver measured each time, they were so close.
