Speakers with tubes

Haven't seen anything like this before has anyone else? Jimbo.

Considering tubes's microphonic tendencies it might not be a very good idea putting them on a speaker.
Then again, what do i know?

 

Is that a really neat idea ... or a really dumb one?

 

Onno, you beat me to it.

 

It is very cool though

There are some small computer speakers with valve amps.

Those LS3 things don't seem to have active crossovers though, just amps screwed on the back.

 

Aopen even have motherboards with onboard sound using tubes:

er....you mean warm Simon?

The idea is just plain daft. This sort of thing is a sign that the audio industry is running out of fresh, innovative ideas.

 

Hey Rob!

If you can remind me of your address I will pop a copy of the new (ish) album in the post for you. I have been waiting to get it all printed nicely with a cover and stuff but I don’t think it is going to happen any time soon. It is a lot better than the one you have.

 

If the tubes were made designed for that app in mind then it could be fine. Tubes have been used in all sorts of hostile environments - big gun shells for example, these saw 5000G and worked fine - ok not for sound reproduction though.
A bit of vibration from a speaker cone could be taken care of I'm sure

 

I have a pair of the smaller VAL tube speakers.

They sound good, they're fun, they're adequately built, it's an amp bolted to a passive speaker, something in the amp rattles, they pick up interference from my LCD monitor, I broke one of the tubes, they're in the loft.

Before I broke them they made music.
