I received a KLH 10in 120watt sub recently, and am not impressed. I understand that it's a discount brand, but could I take it apart and replace the individual speaker with another. I understand that there is a crossover to contend with. Do they have to match in some way? I have a decent 10in speaker I could try, but it is from a regular home speaker. I would get another sub all together, but don't have the money. I would just go ahead and try my little plan, but I don't want to mess up the sub so I end up with nothing.
