Pros: Bass is lifted about 3.6 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Lower mids sit within about 0.7 dB of target, keeping voices and guitars natural. It uses 1 x 10mm dynamic with an easy 24 ohm load.
Cons: Its 2.40 dB spread is less even than the best measured sets.
