Hi All Many years ago I set up the system I still have today, B&W 601 - B&W CC6 - MA rears and a REL QBass sub. I've noticed that the rubber diaphragm on the REL sub has a good size hole and the slightest touch causes more deterioration. I've spoken to REL who can't help as the unit is from the original REL company and directed me to another company who said they can repair it at a cost of circa £100 plus another £30 for transport costs. However I have been looking at replacing the unit myself with some options being a cheap Soundlab unit: Soundlab 12 or an Eminence LAB12 unit at around the £120 mark. Alternatively the auction site has REL Storms, Strata 5 and Quakes that could come in at the same outlay or for spending £100 more. My experience with subs is limited to just living with this one for 18 years so would appreciate some opinions to guide me.
