I wanted some ceiling speakers and thought I knew what type I needed, I spoke to the team at BuyCleverStuff and they went through the options I had and between us confirmed my original choice would be the best. The team however did suggest a number of ways I could improve the setup which I implemented and it's worked well for me. I did have a problem with one of the active speakers (built in amplifier) I setup as a slave which produced a high pitched whine which was noticeable on quiet tracks, I spoke to the team at BuyCleverStuff and they suggested it might be electrical interference from mains cable or more likely the LED down-lighters, they sent me out a filter which they said should cure the problem, I installed it and it did resolved the issue. I'm really happy with the system I chose and the service I have had from BuyCleverStuff, I have already recommended them to friends and family, and would be very happy to recommend to anyone. Great Knowledgeable team and great service.
