My Synergy Horn prototype is shown on post no 105. (Bill Waslo posted it for me. It is a 2-way multiple entry horn built from Bill's spreadsheet and my use of Horn Response. I also built a Tapped Horn subwoofer with a folded 3m length horn and 8" driver. These 3 units are used in a 2.1 system with a Yamaha A1 surround amp and separate electronic crossover and amp for the subwoofer. This is the system I use all the time for listening to all sources. The speakers are the finest for sound quality I have ever built (out of nearly 300). I did not start on this project until I had heard Danley speakers here in my listening room and realised that there is nothing better. At some point, I will purchase a pair of Danley SH95 speakers to use for my own listening and be a reference standard to compare other speakers. In the meantime, I thought I would build my own, similar in design to the SH95. I used a DE250 for the high frequencies and a pair of 6" Morel MW166 drivers for the bass/mid in a closed box (about 25L). Making the cabinets, from 12mm Baltic Ply, was not difficult but took a couple of weeks. There was one aspect of my build that I could have done better. I was too cautious with the mounting of the bass/mid drivers leaving a larger volume enclosed under the driver diaphram than was best from a frequency plot requirement. As a result, the rising response needed a very large inductor to make it near flat. You are struck immediately by the sound quality that a Synergy Horn speaker can deliver in a typical living room (my listening room is 20ft by 20ft by 8ft high, furnished and with bass traps and diffusers). Its the clarity, better imaging and overall coherence of the sound that hits you straight away, making what you hear more real and without the intrusive room acoustic problems. They are so good I am going to build some more, this time a 3-way in the same cabinet. I guess I have been fortunate to hear Danley speakers in my own home and know how remarkable they are. Let me encourage more of you who read these posts to build your own, or purchase some SH95 speakers from Tom Danley. You will not be disappointed, in fact, you are likely to be delighted.
