I recently bought a TEAC LP-R550USB, which is a unit comprising CD/cassette/record player with tuner and inbuilt speakers. Unsurprisingly the speakers are not the best and I'd like to improve things by connecting two auxiliary speakers of better quality. I'm thinking in terms of up to £100, possibly £200, the pair. The amplifier is low power - the manufacturer's spec says 3.5 + 3.5 W, the frequency response is 50Hz-20kHz, and the inbuilt speaker system impedance is stated to be 4 ohms. What specification of speakers would it make sense to buy, and any particular models? Btw they'll be in a room about 4m x 4m, and shelf mounted.
