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.

I seem to recall that I measured your cab, Phil, and found the tuning spot-on.

I guess that shows that it might be possible. But at a price.

This has no doubt been discussed in the past, but is there some software that would allow a band to practice remotely via the internet? I seem to remember that there were problems with time delays. What's the current state of the art?

I've had a few different parametric eq devices in my bass rig and have found never found them useful. Theoretically, they offer the best way of tailoring your sound to fix problems with your equipment or with the room, but in practice I've found that they offer too many options. As long as the frequencies are correctly specified, a broader based five-band tone control works for me. Even then, I find I only ever need to use the low bass and lower-mid bass controls in live situations.

Likewise.

Answering my own question: "With the HF control at max you hear everything upwards of ~3kHz coming from the tweeter. Turn the HF control down and the crossover point gradually shifts upwards so more of your tone comes from the 12” driver, giving a wide variety of sonic options." From the Barefaced manual. Still doesn't make it a "variable crossover". Unless someone can provide a circuit diagram or a photo of the crossover, or explain how a variable crossover can be implemented passively at a reasonable cost, I'll stick with my original assumption. Those who believe in magic are welcome to do so.

What are you basing this on, Pete?

Are you going to reveal this inside knowledge?

It is indeed a crossover, mcnach, but it's very unlikely to be a variable crossover, which is what the reviewer that Dave quoted earlier is describing. Everybody and their dog uses an L-pad on their bass cabs. When an L-pad is used, the crossover frequency does move slightly by dint of the fact that the level of the HF is being raised and lowered. But that's perfectly normal.

Or just use your tone controls.

The F112 has a fairly extended bass response, which sounds beautifully fat and powerful on its own. It goes lower than most other bass cabs, but the price it pays is a lack of sensitivity - the normal tradeoff. It's quite common for players to find an extended low end troublesome in some playing situations.

Would you back that up with some actual information?

Simply put, an L-pad is a volume control acting on (in this case) the tweeter.

I think you'll find it's just a standard L-pad volume control on the tweeter, Dave.

Wouldn't it be easier to paint the baffle rather than tolex it?

Yes, with Winisd or any similar program.

That's very generous of you @rubis. I eventually decided to order a roll - so I'm now well stocked. I didn't appreciate just how big a roll is, but hey, it'll come in handy. 😁

Lightweight amps I've had are the Ashdown Mibass 500, the Markbass LMIII and the Aguilar TH500. I've ended up with the Ashdown RM500. It's got the most sensibly specified eq and does the 'slam' thing that not all lightweight amps do well.

@Lespaul1 Where did you get your LaVoce from? Do they have a UK distributor now?

I'll jump in and say that's a very good explanation.

The Bergantino CN212 contains two drivers rated by the manufacturer at 300W AES. I know because I've seen what they use. Bergantino rate their speaker at 700W. Why?
