The Arizona Audio Video Club will meet at 7 pm on Wednesday, 9/24, at the Trinity Lutheran Church, 9424 N. Seventh Ave., in Phoenix. Nonmembers are encouraged to attend. The club's website can be found at azavclub dot org
This will be a music meeting, featuring a club-members two-channel gear. Speakers are Serenity Acoustics Super-7s serenityacoustics.com/products/thesuper7.html. These are a product of GR Research's Danny Richey. The Super-7s are hybrid mag-planar/dual-12"-bass systems, all open-baffle. Midrange and treble are handled by four custom-built Bohlender-Graebener midrange (Neo-10 PDR) drivers and one 3" Neo-3 PDR tweeter in an MTM arrangement. Bass is reproduced by two servo-controlled 12" cones driven by high-power bass amps that are designed with the servo controls. The Seven's sensitivity is high at 97dB.
Two different pairs of mono amps will be demonstrated: first, a pair of 8-Watt, Single-Ended-Triode amps, Coincident Frankenstein IIs. These use a dual-triode 13EM7 gain-and-driver tube, a 300B output tube, and a 5U4GB high-Voltage rectifier. We'll also hear a pair of WAVAC MD-805m amps. These are 55-Watt SETs using an 805 output and 5751 and 6Y6GT gain and driver tubes.
The system will also include a Conrad-Johnson MET1 vacuum-tubed preamp and an Oppo 95 disc player.
Refreshments will be served.
