Spanish for harmonious, the Armonicos represent my first full on attempt of design and build, start to finish. I wanted something unique in appearance and design, using mid-level priced components, and the ability to be replicated by others. I want to thank Ben for convincing me to try a series crossover design and for his very informative write-ups.
The drivers are the Eclipse W6520R-4 6.5" woofer and SB Acoustics SB26STAC 1"soft dome tweeter. I was introduced to the Eclipse woofer at Jeff Bagby's crossover seminar and felt it to be well worth its moderate cost. Both drivers exhibit a wide flat response with a generous overlap in freq response and low distortion.
The enclosure is formed from a section of 10" diameter PVC pipe. MDF was used to form the top and bottom caps. A 1" thick oak baffle was inlayed for the front. Rustoleum Crimison metallic paint and ebony stain for the front and feet. They are ported using a 2"d aero port down firing and tuned to 42Hz. This gives and f3/6/10 of 39/34/30.
The crossover is a series design (per the ludicrosity rules) and is 2nd order on the woofer, 3rd on the tweeter resulting in BW3, BW5 alignments, respectively. The tweeter is wired in normal polarity. Crossover point is about 1900Hz. I used Solen and Crosscap capacitors. The resistors are Twisted Zistors from Meniscus.
