Fair point, for some reason I'd defaulted to assuming we all tend to leave cabs set up ready to use but obviously, not. Several of the Ashdown Rootmaster series of cabs are shallow enough - the 414, 210 & 112 are all 336mm deep, the 115 343mm, so would all fit. I haven't used them however, so can't comment on their tone.

Note that for most cabs, you'll need an extra few cm behind it to clear the speakon & cable, which usually sticks out straight backwards. That will reduce your useable cab depth to perhaps 30cm or so, which will really narrow down your options unfortunately. @Downunderwonder's suggestion of a curtain rather than a door is looking like a really good idea at this point, if you can persuade Mrs Grapefruit.

Cool, well for the time being I'd say leave it as is at least till you've had the chance to turn it up a bit. The Equal Loudness effect means that as you get louder your perception of bass improves, so even if the low end were to sound a bit light at livingroom volume it might still be viable for your rehearsal use-case, even without adding ports.

As Bill says, there is a gain to be had from porting, but it's modest - less than 3dB. By the way, how does it sound at the moment? Are you noticing it being particularly light in the bottom end at all? Also - how's the back panel & its latch and seal holding up? If you port the cab for more bass, you're also increasing the chance of extraneous noise if the hinges/latch don't hold it closed tightly enough. Anyway, as I am an inveterate WinISD tinkerer, Blue is sealed, Green vented with 2 of these: [url=50mm port]: That's theoretical however and there are a couple of caveats: 1; WinISD's port calculation assumes the backside of the port is at least one diameter away from any boundary such as the sides of the cabinet - you will be struggling to achieve that, so the ports may tune lower than predicted. If they were to tune as low as 40Hz rather then the theoretical 46.5Hz, the curve would look like the bold Green trace here - not much different in this case: 2; Vent Air Speed may be a problem. For best performance, the general rule of thumb is to aim for 17m/s or lower, though some sources do say that for non-hi-fi applications, up to twice that may be acceptable. At the ~33V your BAM200 can put out, the predicted airspeed is this (again, bold = 40Hz tune - in this case that actually plays in your favour): In practice, this is probably less of an issue than the modelling suggests, due to a couple of factors - first, we very rarely play with the amp flat out the whole time and allowing for dynamics in our playing, average power levels should be a lot less than max and second, those graphs assume full power at each frequency, which for an instrument like bass which is rich on harmonics, doesn't happen - our power is divided up over several frequencies for each and every note we play. So, overall, more work for marginal gain - if you're an inveterate tinkerer you may still want to do it but don't expect night & day differences from the current sealed condition. HTH, Good luck, D.

If elderly, or managing any health condition, please ignore the following. 1: Place amp beside your bed. 2: Every morning when you get up, stub your toe on said amp and curse yourself for being daft enough to take advice from strangers on the internet. 3: Wait, that's not supposed to happen - place the amp a bit further from your bed than that. 4: Every morning, when you get up, lift the amp to chest height. Once. 5: Carry on with the rest of your day. 6: Once step 4 becomes habitual, add another rep. 7: Once step 6 becomes habitual, add another rep. 8: Once step 7 becomes habitual, add another rep. 9: Once step - hang on, you see where this is going, right? ... .... ..... X: Once your significant other notices the effect on your physique enough that you're getting more nookie, come back here and laugh at the idea of getting rid of the piece of fitness equipment that occasionally doubles as an amp 😜 If you still want to reduce weight, the Yamaha DBR series are often mentioned as the minimum many pro sound people would recommend for sound quality - they're a little more expensive than the Alto TS but I'd be confident they'd sound better - that being said I've never used an Alto (and a DBR only extremely briefly) so take that with a grain of salt.

Hi, Not quite as smooth as the Pulse 10, the Beyma 10CMV2 looks quite good for a small cab, and is ~20 quid cheaper, FWIW.

Thanks all, nice to see some people from the right end of the country 😜

Hello All, fit like? I'm David, from Aberdeen in Scotland. Been playing electric bass on & off for ~3 decades, done some church stuff but current musical interests are mostly folk, rock & classical. Not currently playing out, just dabbling at home. Mostly interested in the amps side of things, as I do AV/live sound work as the "day job". Looking forward to some interesting discussions. Cheers, D.
