Quilter has something new on the way?

[agedhorse]

You

And that's a huge reason why I'm very interested in a Mesa! When I go down the list of features I want in a bigger head, the D800 and + nail it. But I have an Interbass and absolutely love its sound, utility and convenience. If the new Quilter BB has 2.67 ohm stability and pre master DI, I'd be one of the first to buy it.

can also use the Interbass’s line out into the effects return or aux input of the D-800/800+

I played my BB800 at 2 Ohms for a whole show. No problems at all!

Offering 2 ohm stable operations with a class D module requires a higher level of expertise. That's why all Mesa Subway 800W are stable down to 2 ohm, when other amps from other manufacturers, using the same ICE Module, can only go down to 4 ohm.

There are other company's amps with that module that safely go below 4 Ohm.
Some of them list 2 Ohm as the limit and some 2.67 Ohm (and yes, there are some who list 4 Ohm).
It seems to be mostly based on various heat management approaches.

It's not just heat management, in fact heat management is down the list a bit.

Ok, so... non-engineers (people like me) should stick with with known facts, huh?

Heat is just an easy parameter to discuss, and marketing folks tend to like easy..,

Engineers stick with the known facts. Non-engineers tend to ignore the facts.

Interesting. I'm not sure I would take the risk, but if you play 90 minutes and you don't push the volume too hard, it's probably safe. I wonder what's the risk by the way: blowing the amp, or just see the amp go in safety mode (= silent in the middle of a song until it cools down?)

Pat Quilter said that it would just go into protect mode - interrupt power until the circuitry returns to normal conditions (or close to that, I'm not quoting verbatim).

Yes that's what I thought. OK, not very pleasant to become silent in the middle of a song, but still worth trying.
To be honest, I don't need to run the amp at 2 ohm (I only use it with a 8 ohm cab, and that's already almost too loud for me, LOL), but I would try if I had the opportunity, just by curiosity. On the worst case, the amp goes into protect mode, you just disconnect one of the cabs and finish the show with a 4 ohm cab…

Another good reason to use a separate DI from your amp (assuming you are also running through a PA)!

Exactly

 

[agedhorse]

Note that protection circuits are not perfect, there is always additional risk of damage operating the amp outside of its intended load limits.

Just because you got away with it doesn’t make it a good idea (IME).

Btw, if a sound guy tells me that he kept me on mute because I was too loud on stage, it would mean that I made his work more difficult, not easier. That's not a compliment...

That happens more often than you might think. More often it’s the guitarists that get zeroed, but many bassists generate all (or more than) the volume needed from their stage rig alone. Most sound techs (myself included) are too busy at the end of the show to give you that feedback, but there you go .

I know that it happens. My point was that it is not received favourably by most techs I know...

I think that depends on the stage volume/tone and the audience volume/tone.

As someone wise once said, "If it sounds good, it is good"!

If the soundperson is a control freak that's upset, not about how it sounds, but the fact that he/she/they were not in control of the final sound, then that would not faze me one bit!

There are a few bass cabinets that project in such a way that both areas (stage & audience) are covered without a supporting sound system.

 

[Zbysek]

My point was that significant stagewash makes sound engineer’s job more difficult, not easier.

I don’t see how that depends on anything…
