So, my hartke 4.5xl lasted about two months before blowing a driver. The 115xl is doing fine. So I could carry on gigging I found a battered old 4x10 Hartke transporter and sadly.......I prefer the sound. Its battered to be fair but I have straightened, painted and added spacers to the grill, re-wired it and put a new decal on it. It looks mega. Its also about a third lighter and smaller than the 4.5!!!! Why did they discontinue it?
