Snell type B:any upgrades?

Everyone forgot one possibility, the strongest one - upgraded crossover parts. Don't even think about changing any of the drivers. You will destroy the speaker. But upgraded coils, caps and resistors will make a substantial improvement. If you can get the crossovers out without doing any damage, ship 'em off to me, and in a week you'll have them back, and you'll hear greater liquidity, bass definition, and way less treble grain.

I would agree there - I think the D was the best speaker Snell made, and I owned the A and C/V.

Zaikesman,

Agreed. The J and K were quite good. But the D had a stunning ability to disappear, which floats by boat!

I do crossover and electronics upgrades as a business. That's a great pic of your crossover, and it's nicely laid out, with SOME good parts. But there are at least 27 components that I have counted in that picture that could be upgraded. That would probably be overkill, but at least 12 of them would make a substantial improvement.
