I have heard a number of quarter wave back loaded horn systems. When properly implemented, these systems have shockingly good bass--not deep, but, clean, tuneful and coherent. I am also a fan of some horn/compression drivers, so I am intrigued by the matchup here. These are not a me-too kinds of systems, so I do hope to hear one some day. It would be nice if they would show up at the various audio shows around the country. That appears to be the only way to hear a lot of gear these days.
I am not a fan of relying on internet buzz and reviews, nor for that matter the reviews of major publications. Good sound is a personal evaluation, so the gear must be heard in person. The craziest things are youtube auditions; where nothing at all about sound quality can be ascertained (unique rooms, cheap microphones, variable quality of playback equipment at both ends, a speaker playing back a speaker (so what qualities can be attributed to the speaker under review)). I also think their affiliate program is a bit problematic. If someone is earning a commission for a referral, how "objective" will reviews and even interest posting be?
