There's quite a bit of info on this cab on Talkbass. From what I can gather, none of the smaller drivers is sealed; they share the same airspace as the 15. That's not great for the six-inch drivers in particular and might be why so many people on that forum are trying to repair them. To make matters worse, the crossover only works on the horn.

This is a more advanced project than fitting a different driver in an existing box. You're going to have to integrate three different drivers and get them working together seamlessly. Your best bet, as Steve has alluded, is to find out what the existing drivers are, get the spec sheets, and try to locate the nearest modern, neo equivalent. Keep the existing EV crossover (which also might be in need of repair, by the way) and cross your fingers. Unless you're lucky enough to pick some up secondhand, you're looking at a minimum of £400 for new drivers. If it works, you'll not only have a much lighter cab, but it will also handle more power. If it doesn't work, you'll just have to resell your drivers and swallow the loss. Interesting project though.

Check out funkle's build thread here: That's for the CNC cab kit, but the same principles apply if your cutting your own panels.

You'll find the plans and the parts list on page one of the thread, @martyy. Build the cab without the horn and compression driver if you find the electronics a bit daunting. Add them at a later date if you want.

I'd be reluctant to blame Westside without knowing what deal they had with Mesa. As far as I can tell, prices in the rest of Europe were comparable with those in the UK.

Quite probably. 😊 It wouldn't be the first time.

And the 650W drivers are?

The cone reproduces different frequencies by vibrating at different speeds. At low frequencies it moves in and out, say, 40 times a second. To reproduce high frequencies, it moves in and out at, say, 2,000 times a second. To reproduce a low frequency and a high frequency at the same time, it has to move in and out 40 times, while simultaneously moving in and out 2,000 times a second. That's just to reproduce two frequencies. When a speaker is asked to reproduce a musical signal, it has to reproduce many different frequencies simultaneously.

Yes, that's quite a useful test track for highlighting differences. I might start using it myself.

Looking forward to your comments.

... and black and white TV.

There's an interesting comparison here of the RCF 745 and its wooden cabinet equivalent, the NX45: The benefits of the wooden cabinet are clear to hear, with the 745 suffering badly from boom/tizz. Surprisingly also, vocal reproduction on the NX is fuller and more natural. At least that's what I'm hearing. As Russ mentioned on a previous occasion, the differences would probably never be noticed by your average punter, although for many (including yours truly) that's never been a criterion. Thoughts?

Bit late, but I'm fairly sure that the CN112 and 112EXT use the same 12" driver. So they should sound very similar.

It was a long time ago - the details are lost in the mists of time..... I just recall it as being a bit of a mess and not at all helpful. So, did it get you reading, @Coilte? As I'm the only one in this thread who didn't get on with it, I agree with your "to each their own".

I had the Bass Guitar for Dummies book and found it worse than useless. What can I say?😊

Very nice paint job.

Mods, none of Greyparrot's videos show in the Firefox browser.

Aha. Your link said £75, which is why I asked. 😄

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:
