Further to a question from Wellhouse some time ago, does anyone have experience of Poket custom door builds for A4 B5 front doors - these cost £175 per pair, but would enable 6.5inch speakers to be fitted - would they be "solid" enough to be worth the money, if used with dynamat or similar?Or do you think 5.25inch (decent make like diamond or rainbow)in existing door cards would suffice?One more (daft?) question - does anybody fancy making some builds for the B5?
