Right - speakers ordered, and should arrive Monday
Dropped in at my local ice showroom after work today, and picked up 12 sq ft of R-blox extreme for £45 - seemed pretty resononable as I won't now have to fork out for postage - was tempted to go the cheap route - e-dead is available on ebay at £49 + postage (£6) for 30sq ft, only from what I've read it's just re-branded foil backed flashing, but I may be wrong.
My next step will be to deaden the standard door pods and surrounding area, but relating to my original question, if the speaker won't be utilising the door cavity, is it as important to deaden the door skins? I intend to deaden the rear of the door trim behind the speaker and sandwich some dense foam between the door and the trim.
Sorry for all the questions, but when I tackle a new task - I like to do it properly!!
