Hmm, Volts. Nuff said.
Actually, maybe not.
Just to clear a few things up.
These look like early Volt 10” drivers with the original ABR grills.
To the best of my knowledge Volt didn’t make a 12” unit until they produced the radial chassis.
The early Volts B250 came with a natural finish Aluminum chassis and a grey, coated paper cone. The later Volts under the same model number but with a .1 suffix had a couple of revisions.
The later chassis came in black and the cone coating was changed giving a slightly stiffer cone and a black finish. The roll surrounds also changed with an increase in thickness making for a slightly less compliant suspension. (I used the new roll surrounds when I last rebuilt my Volts)
If anyone is interested in the original specification sheet for these, drop me a PM and I’ll copy one up for you.
I’ve been very gentlemanly and edited out my response to Dave’s Boom Boom comments.
All I can say is you either know, or you don’t.
Volt drivers will with a suitable crossover work just fine with a valve amp but as Andy points out, probably not with some 5 watt SET amp. With a resonant frequency of 20 Hz a little care is needed with enclosure design but in general Volts are less likely to boom than most other bass drivers currently in production, commonly with resonant frequencies of between 60 and 100 Hz, given a sympathetically designed enclosure.
I’ve built 4 sets of speakers using Volt drivers now (B220, B250 x2 and RV 3853) usually accompanied by Scanspeak mid and hi range with excellent results.
While as Andy mentions they are expensive, for those interested in quality and “out of the box” thinking in loudspeaker choice Volt drivers are about as good as it gets.
As Mark mentions, at the current price its worth taking a punt just for the Volt drivers which new would now cost in excess of £500.

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.
