Marshall Middleton II: $330 Amazon eBay
Older model: the Marshall Middleton (ranked lower, rated 4/5).
Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
Cons: Bass boosted which drowns out the midrange. Dip around 200Hz, peak at 1kHz, dipped at 1.6kHz. Strange frequency response through the mids.
