I was at the local music store and I was playing through a hartke stack. 350 watt head through, XL 4 x 10 cab, and a 1 x 15 XL cab. THe sound was great, I reallyu liked the punch I got from the rig. However 2 things plague me. The wattage rating on the 4 x 10 was 400 watts, and on the 1 x 15 it was 200. The rig had a lot of response and performed well, however the wattage I wasn't sure about if it would give me enough room. I was just wondering what you dudes thought of the hartke XL series cabs?
