Here's why I think it also has something to do with the cab. The SLM-to-now towel bar cabs are a little bigger than the straightbacks. So the higher amount of internal volume, while not substantial, is just enough to make the bottom end more woofy. Also, I have to add more 800 to get more even response, but that may just be the head itself, since I hear subdued mids to a lesser degree in my rig's 1st channel. Believe it or not, the place in DUluth actually gave me a CL/810E. It's made by LOUD, but it works and the head sounds just like other CL's I've played. But now that I'm more familiar with the 69 in a band setting, I so hear the woofiness of the cab compared to mine. Some people may like it, but I like accenting the lows at 125-200 and no lower. But you are 100% correct that the new speakers don't have as much high end as the CTS's. The new one sounds like it has the proverbial blanket over it. It's a good cab, but it could be way better if they quit trying to make it work with a 1000w power amp.
