AS you may have seen before in an older thread I was having problems with my 1001rb-II and my SBX115-II. I discovered the problem and it turns out the main woofer has blown. Because it has blown I doubt I will be able to get warranty on it, but I had the idea of replacing the main woofer with a new one. http://www.maplin.co.uk/module.aspx?ModuleNo=20901&doy=4m9 If you take a look at this link, you should see a: 380mm (15in) 400W Bass Speaker Manufacturer: Eminence I know that GK use this manufacturers speakers for the SBX cab, but I'm not 100% sure which speaker is the exact one I'm looking for. Although this speaker fits the specifications of the cab I want confirmation first that this is definately the one I am looking for. _______________________________________ This is my first cab I have ever owned, as I have upgraded from a 30w practice amp. Until now I have had to use other peoples rigs for shows and I decided I wanted one so I could get my own settings just how I like them. But as I am pretty inexperienced with cabs, I had a few questions in mind which I'm sure you guys can answer If you were to suddenely play the amp at a very large volume it possible it can blow the speaker right? If so, shouldn't these amps be made to cope with these kind of volumes? Especially when you are going to being Slap, because slap is so loud and punchy its going to cause a lot more stress on the speaker and couldn't it break it? Again, if this is the case how are you supposed to get to a high volume? If I was going to do a show and needed a lot of power, wouldn't it cause damage? Thanks for your help.
