How much??????

No, in fact that's all you need to do. Halve the internal volume of the cab and halve the porting (which will maintain the current port tuning as stated by previous posters) and you've got yourself a 2 x 10. If you're doing this for fun and to learn, it sounds like a good project. The good thing is that you could take all the parts like handles, corners, input panel, etc. from the 4x10, saving you a lot of hassle. You could certainly keep the tweeter if you wanted, but the crossover values will need to be changed. If you provide the crossover details, I'm sure someone on here will tell you what to do. If it works out, you could then build yourself a 1 x10. A build thread would be good.😁

I look for the very last note in the piece. It's almost always the root note of the key. There are exceptions, but they are pretty rare.

Gerry answered my plea on here for a small, cheap mixer and came up with the goods. The unit I received was in brilliant condition and a bargain at the price he asked. Very happy.

If the event goes to plan, there'll be at least three Basschat 12" cabs at the Bash - probably more. I'd be interested in a comparison with the BB2, too. Last year, nobody brought one - so we couldn't compare, although we were able to compare it with a Fearless 3-way. That was very interesting. The previous year, we ran a head-to-head which included a tweeterless Barefaced 12 but, if memory serves, the consensus was that the horn on the Basschat cab gave it an unfair advantage.

Thanks for the tip. I really enjoyed her music and will be listening to more. Yes, very good guitarist but even better singer, IMO. I'll raise you:

I think most people would consider SRV a blues guitarist. Whether he's better than BB King, for example, depends on what you consider important - like any discussion about 'who's best'. Steve Vai's pretty amazing, IMO. And Gary Moore.

Only if they're oxygen free.

I'd have thought that bass players would appreciate Brian May's talent, as it's based on musicality and inventiveness rather than how many notes you can play in a second. There will always be somebody who can play faster than you, but crafting the kind of solos that Brian May produced is much more worthy of respect, IMO.

I was involved professionally in the cable business for a few years and can confirm that Neutrik plugs are the business. I wouldn't contemplate anything else. If I needed a new cable, that would be the first thing I'd look for.

Nice review.

Indeed. The 112SL might actually be 99.9dB at one particular frequency, but definitely not over the entire frequency range. Also, defining the sensitivity to a tenth of a dB reeks of 'specmanship'.

You really do need to take manufacturers' specs with a large pinch of salt. They exaggerate a lot. A figure for sensitivity is meaningless unless you know how it has been calculated. Ideally, that means a frequency response curve measured under standard conditions – the kind of thing pro speaker system manufacturers provide. Anybody can make a bass cab that has high sensitivity in the midrange, but unless the LF can keep up, it will sound unbalanced. Anything between 94dB and 97dB is a reasonable figure for a medium sized 12" cab. 99dB is almost certainly not an honest figure. Doesn't the MB have a larger cabinet? If so, it might be marginally more sensitive at low frequencies (where it counts) than the Aguilar, but not much.

With these cabs made from aluminium and carbon fibre, special attention has to be given to preventing resonance. The original carbon-fibre hi-fi speakers I remember had heavily damped and curved GF panels because of this.

It's likely to be an open circuit somewhere along the line. Check the wiring from the output through to the midrange drivers. A multimeter would help.

That's the only explanation I can think of, and it might make sense for open-backed cabs.

As has capacitor burn-in and cable burn-in. The hi-fi market is full of marketing myths.

The kiss of death.

I have some Sennheiser 650s (retail £300) headphones and some 580s. You really have to concentrate hard to hear any difference. You can pick up a second-hand pair of 580s for about £70 on eBay, although they sometimes go for a lot more. If you like, you can replace the foam parts for just a few pounds by buying the copies from China.

Is that the best you could do, @Jus Lukin?😀

In fact, if you use enough braces, you could build a cab from paper. 🥴

I don't have the SM212 but I have another 12" Beyma driver. It looks like they all take the same spade terminals, which are 6.3mm. You could always get your ruler out to check.

Agreed. The constant directivity horns that most cabs use nowadays all need to be equalised - so there has to be some form of equalisation going on for the HF at least. What the people at RCF might be getting at is that they're not using DSP to iron out problems with the drivers. In other words, the drivers they're using are capable of producing a flat response without too much eq. That's certainly possible.

We measured the impedance. If you haven't got that facility, the rice-on-the-cone method works too. The tuning was meant to be 50Hz.
