After sifting through this forum I'm still in need of some personal advice. Im very ignorant in terms of amps - Im still using a 100W Trace Commando from ten years ago! But I want something a little more powerful. With my budget Ive found these which I intend to put together: Amp: http://www.thomann.de/gb/warwick_profet32_basstopteil.htm Cab: http://www.thomann.de/gb/hartke_45xl.htm I like the response range and aluminum speakers on the Hartke cab. Can anyone see a problem with putting these two together? The amp is 300W @ 4Ohms and the the can is 400W @ 8Ohms. Im still a little confused about impedance..... And how do you pronounce "Hartke"?! Any help would be great! Cheers.
