I mocked up another baffle and fitted a Kef B160 (SP1366) which smoothed out many more wrinkles than I had hoped, to be honest. I also stuffed the ends of the pipe with some cushion filler, as suggested by Martin. There is a much nicer balance now between mid range and bass. The SP1366 is a curious thing - there appears to be space for a tweeter in the centre of the cone. All I could find out on the net was that deeply confused people are searching for tweeters which might fit in the several versions of the B160! Has anyone used these little drivers and fitted tweeters? What does the fact that there is a hole full of fresh air through the centre of this driver do to its performance? Does it have to be fitted with a tweeter?

Alternatively, I rather like Edward's suggestion of a decent car speaker with all the bells and whistles included - any recommendations?
