I have a brand new LX550. class D. weighs 8 pounds. opened it to play it in the living room for 10 mins. getting out of bass for now. will come with original box and packaging. 500 watts into 4 ohms. hartke is very particular in always stating this amp will run constantly at 500 watts. so that's not its peak wattage, thats its always wattage. built in compressor and drive that both work really well. has a mini tube pre amp. headphone 3.5mm and 3.5mm aux input
