    Recently acquired a small closed back 12" speaker cab.

    Tried it (using correct ohm) to a couple amps and it sounds a
    tad flubby. I think there is some kind of hemp speaker in it.

    Do ceramics or alnicos sound better in closed back? I know
    there is a lot of sound and pressure bouncing around in
    those things. I had 4x10 closed back hundred years ago
    that sounded decent. But, a 12., not sure.

    Ideas?

    can you show us what cab you acquired? Or tell us the brand and model if it's from a known manufacturer. Also the speaker make/model would be quite helpful to know.

    Closed backs sound dreamy to me in a music room, but flubby and terrible in a gig situation. Especially if the cab is too deep. That's about all I have for you. But a Hemp cone probably not helping. A brighter speaker may help.

    It looks like a re-branded C-Rex - which seem to fall into the 'love it, or hate it' kind.

    I would offer two suggestions in order:

    Stuff the box with polyfill and see if that does the trick for you (that's the lower-cost first alternative)
    If not, do like schmee said: swap the speaker to a tighter/brighter sounding one.

    remember - if you ever build a closed-back cabinet, make the back removable, in case you ever want to change it to an open-back cabinet. Supro apparently didn't think far enough ahead.

    What amp are you driving the head with?
    Ceramics and alnico's can both sound good, but "sounding good" is super subjective. I had ceramic Warehouse G12C/S for a Bandmaster, and have Weber Alnico 10's in a tremolux cab. Both sound good but different.

    with your Supro cab, it was designed to sound good with the titan amp - with other amps, YMMV... and as to why they didn't build it as a convertible back to be open/closed/partially closed, it's an extension speaker cab for an open back combo.

    Yup, so true. I use two panel backs -- the jack is attached to one (usually the upper), the other is removable with two (or maybe four) screws.. easy and flexible.

    I agree that another option worth trying is to convert it to an open back. I tend to prefer open backs at gigs because the sound spreads around more. The sound coming out of the back and sides of the amp is like a monitor for the other guys on stage and I think it also reduces the overall beamy-ness of the amp going out to FOH.

    Funny - I prefer the opposite if we're playing on a state close to the wall, as otherwise it's difficult to control how much amp is in the mix. I used to gig with my Princeton reverb for shows where we knew we'd have excellent monitors, time for a soundcheck, and the wall was 15 feet back and covered with pipe & drape. For shows on a tighter stage with amps against the wall, I'll bring my Tremolux or the MAZ18, both with closed cabs.

    Definitely a personal preference, but also depends on the wattage and what that extra bloom does to the mix. Not sure on the beamy-ness, but that could be phase cancellation as the rear signal mixes with the front...

    Maybe borrow & try a 12" celestion gold in ported close back & beam blocker. See what you think for lead. Rhythm I'd suggest g12-65 creamback less blocker. JMO & experience.
