I got a small 1x15 bass cab that I've had for years that has a blown speaker. My brother wants to start playing bass a little at home so I am looking to find a cheap 15 to get him started until he decides if he wants to stick with it and get a decent cab. Can anyone tell me a source that I can get a 15 inch speaker that will work for this that's on the cheaper end. I'm not really looking for sound quality, just something that will hold up so he can hear himself. Thanks in advance!
