I am looking to update the mains and possibly more in my Kenwood HTB-505 system. I really would like more bass from the fronts in order to get an all around deeper sound. The mains right now are dual 4 in speakers with a 1 in tweeter. I was looking to spend around $200 for a pair of new speakers however this could go up to a max of maybe $300. I have been looking around and so far the speakers that tempt me are the JBL N26(not being made anymore I don't think) the JBL E30, and the Infinity Alpha 20's. What do you guys think?
