The flat bit is meant to go to the side where the rebate is - at the front. In my case it didn’t matter; either way I fitted it there was enough clearance to install the front baffle. So I just did it how I felt. On my kit, which has been tweaked since, the pre-drilled holes for the handles were large; bigger than would accept a wood screw. So I used T-nuts because that’s all I could do, in that case. But it also makes an insanely secure handle, lol.

I like the GK amps. Also Tecamp. Both put out a ton of power, when measured by lab tests at Bass Gear Magazine. The GK amps have more voicing to them, but once set flat are powerful and adaptable units. The GK MB800 is great. The Tecamp Puma 900 or 500 (or now, Eich, since the company changed up) are powerful and neutral amps. A bit too neutral for me, but easily coloured with fx etc.

It's a great cab, I like BF. I'm just warning @Al Krow to be careful about how much stock he puts into manufacturers claims. Yes, even BF. A cab with significant output at 30Hz would either be huge, or suffer severely reduced efficiency in the rest of the frequency spectrum, in general, depending on number and type of drivers. Acme B1/B2/B4 cabs, for example, do have reasonable output at 30Hz, and suffer hugely from reduced efficency as a result. I think they sound great. But you have to carry twice the amount of drivers compared to other manufacturers to get a similar volume because of that huuuge extended low end. And then often you have to HPF that low end out in real world spaces....

The frequency range sounds optimistic, chaps. I have a One10 and think it’s great, but if you seriously think you’re getting significant output at 25 Hz or 30 Hz from even a Four10, I think you’re being unrealistic. That spec range is possibly the F10 for the cabinet, maybe, Alex does not say on the website. Nor would you actually want a lot of that output at that range. It’s very messy indeed in the real world. You end up needing to HPF a lot of that out. I would say output from 50-60Hz on up is important. The critical B string 1st harmonic is 60Hz, the critical E string 1st harmonic is 80Hz. Amplify those well (which these cabs do) and you will sound like a proper bass.

Yes, moderate volume jazz. Piano and sax. Well within capabilities of cab. Set the amp flat and used controls on bass/hand position to manage tone. Killed it. Edit: of course the real test is with a drummer. Not yet for me though...

Just sold my Peavey GV to Clement. Very straightforward, good communications and quick payment. Deal with in great confidence! Thanks once again.

@basstone I might be interested in a cover depending on cost. Do you think it should be a padded one, or just the tough cordura type cover?

Nice review. I totally agree the extended top end. The treble really comes out on this cab. I like how it is presented though, not harsh. But I definitely shelve back the treble on the amp a bit or use the tone knob on the bass. I obviously approve the use of a GK amp with the BC cab. Lol. Yours is probably a better power match than mine.

It doesn't look right there. I'd pick the back of the cab somewhere - sand off a bit of tuffcab if you have to.

Just used mine again last night at another jazz rehearsal. Punchy and clear tone; I love this cab.

@basstone your progress is rapid and I’m enjoying seeing it. I await your review with interest.

Nice. Some of the reviews of that online are quite negative....how have you found it?

http://graciestands.com/performance-stands/ I am contemplating one of these for the future. Not quite yet though.

@basstone gotcha. Nice.

@basstone I hate to say this...but... That support you have glued across the front is meant to be across the inside...in the rebate that runs roughly in the same line where you have glued it. 🤐 However it may still work the way you have done it. @stevie will need to comment. Or is that an extra bit of batten you have made yourself and glued across the front? Pete

Having played a lot of cabs, including those with the 3012LF woofer (like the Audiokinesis Thunderchild, the Fearless F112 and the TKS 1126), I suspect much of what can make them sound ‘hollower’ in the mids is how well the cab balances throughout the frequency spectrum. Basically the 3012LF is so bass heavy (which is wonderfully fun, but mostly excessive in my real world use) that the mids sound very muted/polite in comparison. However they are still there. If you don’t go in knowing this and being ready to subtract the lows a bit, or EQ in some mids, then the 3012LF equipped cabs can seem a little tame. They also suffer from a few dB less broadband efficiency than other woofers with less lows, which doesn’t help. The BB2 woofer is 3012LF based but IMO clearly has significant engineering tweaks to reduce the huge low end. I suspect it ends up acting a bit more like the 3012HO. It also is put into a box that suits the driver, so it ends up hugely efficient/loud. I like how it balances ‘top to bottom’ so ended up with a similar FRFR cab designed by @stevie. As you both know.
