Why the Q150 over the Q350?
Short answer: KEF's 5.25" coaxials are state of the art.
The larger ones are more suitable for multimedia and today's lousy recordings, with synthesized instrumentation and autotune manipulated vocals. To very good music recordings better loudspeakers with the 5.25".
Magic is only achieved with the little ones.
Bring reference recordings and listen to them. For example, Hotel California.
