Wow thanks for that, that's a great help and that 5" soundlab speaker looks perfect - and what a bargain price! I can't fit anything bigger into the enclosure unfortunately, I'm building the amp into a vintage radio box, otherwise I'd be all over that 8" celestion, but I might try one of their smaller speakers for comparison.

Thanks again,
Chris

Hi,

I've scoured the internet and failed to turn up the information I need so please forgive me if this has already been put to bed.

I've built a 386 amp (Runoffgroove Ruby), that's all working fine. I just can't seem to find a suitable small speaker. I'm looking for something in the 4-5" range, I've tried a few hi-fi speakers, but as you might imagine they produce nasty buzzing when you get into overdrive territory.

Just to kick off, here's what I've discovered already:

The Pignose 7-100 has a 5" driver that sounds great, so someone must make these things!

Frequency response is relatively easy to account for with low and high pass filters in the circuit.

Jensen do a 5" guitar speaker that looks like just what I want, but it's very hard to come by here in the UK. If anyone can tell me of a UK supplier that would be great. I have found shops in the states that will ship it to me, but the postage is more than the cost of the speaker!

In a previous post, member "phatt" stated that guitar speakers need to be "low compliance" (stiff), as opposed to hi fi speakers that are high compliance (wobbly). I have been unable to turn this information into a meaningful search term - googling "low compliance speaker/driver" doesn't bring up anything that looks suitable. How can I find a low compliance 4" speaker?

Any advice would be most appreciated.
Thanks!
Chris
