I am currently using a pair of Harmon/Kardon speakers that came with a Dell PC 15 years ago for recording my tracks at home in Audacity in my cobbled together home studio which currently consists of a half decent PC, four guitars (inc Bass), Couple of Mics for vocals, a Zoom G3 and an M Audio interface.
The speakers are ok but the issue I seem to find is that they dont handle the bass very well so when I eventually play the track on a decent sound system its often way too bass heavy.
I dont really want to spend a fortune if possible, just need something better that will plug straight into the back of the PC. I notice there are a pair of Mackie CR3's for sale in the classifieds for sixty quid. I think they are about £80 new.
