100mm max diameter suitable for 2.5 litres

I agree the neo 4Fe32 is a smoother beast above 8k, if the specs are accurate, regardless of impedance, and to varying degrees.

But the 4FE35 is not bad at all, and for £10, and not £30, even better. With some luck I should be able to tweak the notch down to 8k

Any good sources for 12" diameter sonotube?

I have a whacky idea brewing


I have to admit to not paying much attention to MA recently, and also, to be fair, I havent seen them half as prolifically as a few years ago.

Don’t know what the 4F will do, but the 3F i have is quite decent. In a 2.5 litre uFai-Ken (and the MA & Fostex versions), you are getting something like 75 Hz F10, anechoic. In use near-field, especially if near wall/desktop “room” gain should be significant, won’t play loud real low but likely won’t need to.

If you can find some 3.5” A6.2m or p, they fit 2.5 litre box.

I know their were some in France, i have a few pairs. KJF has none, D’Archer in Oz has the A6 metal (he has some of the more sought after A10p too)
