Several years ago I bought a Hartke 1155 Combo. This combo came with the 3500 amp head and a cabinet consisting of a 15" woofer and a 5" tweeter (w/the classic Hartke aluminum cones). I absolutely loved it but my car got broken into and it was stolen. Unfortunately Hartke stopped making this combo several years ago so it's been a bit difficult to replace it. However, a couple years ago Hartke came out with its VX line (VX=very extreme) and offered a combo with the same 3500 amp head @ 350 watts and a 4x10 cabine and has paper cones). This was as close as I could find to the old one and bought one sight unseen from Zzounds.com. It sounds very good but I have to play it at volume 8 or 9 to get it as loud as 3 or 4 was on my old combo. just a huuuge disparity in capability. What could this disparity possibly be attributed to and how could I mend it? Thanx a million.
