    I have a Dr.Bass 212 cabinet

    It is 8 ohms, with 2 Delta 12B speakers.

    One speaker is sounding "fuzzy" and needs replacement.

    It is about an $80 fix, but I thought I would ask forum folks what could be recommended for upgrade.

    Any ideas?

    Problem is, 16 ohm driver selection is very limited.
    The Delta 12B drivers lack xmax and lower frequency response.

    I got the 212 cab as a one cabinet compromise to handle all my EDEN WT800 "A" series 800 watts.

    Thanks for any help or suggestions

    Are you CERTAIN its a 16 ohm driver?

    Usually 8 ohm cabs are made from two 4 ohm drivers wired in series.... lots of 4 ohm drivers out there to choose from.

    It would be best to leave it as it was designed, and either recone, or replace with the same spkr. You don't want 2 different drivers in the same box. And also, no matter what it may be "rated" for, very few 2x12's will actually handle a full 800 watts at any useable frequency.

    +1, especially one loaded with Delta 12Bs, which are displacement limited to about 75 watts each.

    Since the Delta 12B's seem inept in this application, both need be replaced with "real speakers" ; at 16ohms, faital pro 12PR300 might work well, other possibilities include 8ohm speakers, I then will have a 4 ohm cabinet and have more driver choice. I can use half of the WT800 fora 4 ohm load @ 400 watts.

    What "real speakers" would be suitable for this cabinet? This is the smallest size 212 cabinet possible; 20.5" X 25.5" X 15" there are 2 4" round ports , about 4" deep

    Deltalites? I found this"pro woofer" for $47.57 at MCM electronics: •Rigid die cast frame
    •Treated paper cone
    •Treated cloth accordion surround
    •2.5" high temperature voice coil
    •67oz. vented magnet Specifications:
    •Sensitivity: 96dB (W/M)
    •Impedance: 8ohm
    •Re: 6.3ohm
    •Le: 1.20mH
    •Frequency response:
    •30Hz~3.2KHz
    •Fs: 36.2Hz
    •Qts: 0.41
    •Qes: 0.48
    •Qms: 2.82
    •Vas: 121.67 liters
    •Xmax: 7.0mm
    •Overall frame diameter: 12.28"
    •Required cutout: 11.1"
    •Mounting depth: 5.51"



    maybe I need to forget about my 212 cab and start over and build 2 Jacks or a 15/6/1 ?

    A cab that small..... You should look into Eminence 3012HO's. They are really nice drivers and they excel in small cabs. They have a bit of a bump around 2.5k but it can easily be EQ'd out if it bothers you.

    after replacing the Delta 12B with the 3012HO's in the 212 DRB DR Bass cabinet, I can consider one more negative post about DR. Bass. To have advertised the 212DRB cabinet as capable of 1000 watts handling was completely misleading. There just are not any 16 ohm speakers to make a workable 8 ohm 212 cabinet. I question the 212 Avatar claims as well. No one should be putting anything less that the 3012's in a 212 bass cabinet! I would bet the epifani ul 212 contain variants of the 3012HO.
