Madisound and Zaph Audio are pleased to offer the Zaph Revelator Tower. The ZRT has set the bar for easy to build high-end speaker kits. Once again, we would like to thank John Krutke for his design work and overall contribution to DIY speaker building. Full documentation of this design can be found on Zaph Audio.
The ZRT is an extremely versatile premium speaker kit utilizing Scan-Speak Revelator drivers. The 2.5-Way configuration is best as a larger ported tower design.For those planning to integrate with a sub, a smaller sealed box is also possible. The tweeter used is the extremely popular Scan-Speak Illuminator “AirCirc” D3004/6600 1" soft dome. The mid/bass drivers are the Scan-Speak 18W/8531G. This 7” slit paper cone driver is widely considered one of the best mid/bass units in existence. The combination of these drivers and Zaph’s design expertise has yielded a world-class speaker system.
The ZRT 2.5-Way tweeter crossover network uses ClarityCap CSA capacitors in series circuit, Solen Fast Caps in parallel circuit, Mundorf metal oxide resistors, and air core inductors (please note, the older-style SA caps are shown in the picture).
The woofer crossover consists of Sidewinder air core and Sledgehammer Steel Laminate inductors in series circuit, and MDL poly caps in the parallel circuit. The crossover holds to the exact DCR inductor values called for in the design. The remaining parts choice makes the most sense for the required values and high-end level of this kit.
These crossovers come assembled, with each mounted on their own Matrix circuit board. This allows for bi-amp/bi-wiring if desired, and flexibility in cabinet placement.
We do offer several crossover upgrade options from the drop down menu. Please note: the upgrade crossovers will come assembled on larger circuit boards than the standard version. Goertz Copper Foil upgrade uses 16 awg for L8 and 12 awg for L14 to hit the target DCR values.
A ZRT 2-Way version is also available with a single 18W/8531G mid/bass driver. This configuration can be done in a ported 38 liter tower cabinet, or sealed in the 20 liter cabinet. See Zaph Audio for more details on both the ZRT 2-way and ZRT 2.5-way.
