O.K. I finally got the L300's and have been listening to them. Do they have more bass than the speakers I made with the 515B and 902-8B HF drivers as one member inferred? Not on your life! I had a lot better bass with the Altecs, but more mids and presence w/L300's but don't have the warm kick back feeling. More harsh it seems. Am I happy? I guess. I didn't have original cabs so no matter how nice of a job I did on them nobody wanted them as opposed to the L300's that I can probably sell if things get that way. The bottom line is I don't think they are as bitchin as everybody seems to think. Not to say they are bad, not so just not as good as I expected. I need one JBL insignia for a grill face and a peg and a method for removal of the old one for the same grill. I also need to know how to get to the speaker terminals, the plastic is broken off on one of them and I need to replace the connection in the rear. Do I remove the Woofer or go in thru the back? I am seriously thinking about sending the check back and keeping my Altec stuff.
