Just a quick update - i've uploaded the video's so you can get a first impression. Because of the equipment i used...i.e. a phone cam it _won't_ give you a true impression of the volume change (see ear nuts comment earlier ) but it should give you an approximate idea of the tonal shift.

I've got a mate on the blag for some professional recording equipment which will hopefully capture a more accurate sound.

to put it in perspective, the second clip could be heard well down the block and no doubt further.

I'll put a third 'rough' clip up once the extra baffles arrive and once i've got proper recordings i'll try and put a bit more of a complete review up.

All the best,

Ant
