After living with my DIY Back Loaded Horn loudspeakers for more than 2 years, I think its time to share my listening impressions with you.

First of all I recommend you ( if you are planing to build this design), to take the time to experiment with setup and placement to get the best of this kind of speakers. The sound produced by these specific BLH's is affected both by the behavior of the speaker in the room and the size of the room.
