Based on the principals put forth byMr. Tetsuo Nagaoka the Sachiko is a high quality double horn speaker. Very nice speaker, with a minimum of 96db sensitvity....lilkely closer to 98db. Works great with tube amplifiers, chip amps, and lower powered solid state. I have run them with as little as 1.5 wpc from a Type 45 based amp, but thats as low as you would want to go with these speakers. These double horns are quite sturdy, they measure 72 inches tall, 19 inches deep, and 13 1/4 inches wide. Built from birch plywood with a clear finish. Weigh approx 125 lbs each, so this is going to be a pick up sale, unless you want to make arrangements to have them shipped. Located in Eastern Washington..just outside of the Tri Cities Pasco/Kennewick/Richland.....zip is 99320
Drivers are first generation Fostex 208 Sigma, this is an 8 inch full range with cast basket. This Sigma series were the preferred speaker for Terry Cain in his Single and Double horn speakers. When Fostex discontinued this speaker, Terry was forced to use a super tweeter to help out the 2nd generation speaker, and it never worked quite as well. These are an outstanding driver. The cabinet is drilled to accept the 208, or the Fostex 206E, which is a less expensive driver with some compromises. I had the 206 in the cabinet, but was far happier with the Sigma series.
Speakers are wired with a double run of Cardas SE15 wire, Cardas copper binding posts, and the compression chamber is lined with Parts Express Sonic Barrier.
Single driver speakers excel at imaging, which these do. The tonal balance more balanced than the Audio Nirvana Super 12 I used before these. The cabinets are tuned to 50 hertz, and the smaller Fostex driver does not have quite the impact that the 12 inch AN driver did. However, blending a sub to the Sachiko is far easier, and a smoother blend. I use an Infinity Cascade 15 with it.
I sourced the cabinets from a builder in California, who built a few of these as a trial. So in some respects this is a semi DIY project. The builder used a very small brad to clamp the joints on the internal horn panels, and then filled over them. Very difficult to see unless you are right next to the speaker, and know what you are looking for. Still one step off true cabinet grade workmanship. There is a mahogany baffle to raise each driver, one has a small crack on the edge. Was that way when I got it, and it does not affect performance. It could easily be filled and sanded, I just never got that excited about it.
Cabinets are wired with double runs of Cardas SE 15, Cardas copper binding posts, and the compression chamber is lined with Sonic Barrier. heck the drivers and parts for this speaker account for $700 alone. This is a very cheap way to enter the world of single driver speakers, for not a lot of money. This is a proven design, and is actually very close in principal to the Cain and Cain Big Ben speaker, which sold for $10K.
Reduced to $900
Sorry about the quality of pictures, they should be good enough to give you an idea of build quality. I can provide others on request.
