Seeing how a lot of people seem to think the 8in speaker is not cool in a valve combo I decided to experiment with a 10in one. Had a look at a few celestions and picked a 16 ohm 10in creamback. Bit of a rough and ready 'proof of concept' so far. back of speaker just clears the main chassis. But I will move the front panel forwards a few mill to be on safe side. Lot more punch and bass from the new speaker, but rather brash, which was not what i expected from the description of the speaker. Will see if it changes after a few hours break in. Oh well I was gunna post a pic, but no option to attach to post.
