Speaker Systems and Modular Speakers
All my speakers are manufactured to Rolls Royce standard. The cabinets are made by a very experienced craftsman in Taiwan. Horns are milled individually by CNC routers. The piano finishing is performed by the Kawai Piano Company in Taiwan. I hand-build the cable, the crossover, assemble and test the speaker. It takes me 10-12 weeks to make a pair of speakers.
12" 3-Way Speakers
The three models of this series are the backbone of the 3-way systems. They offer state of the art performance in a cabinet of reasonable size which are suitable for rooms as small as 20 square meters (200 square feet).
12" 3-Way V1
Work began on this original version in 2008. Its development took many years. Much of the work was done in perfecting the twin horn technology in which the midrange and high frequency horns must work in union. Production finally took place in 2016.

2-way Systems
The 2-way systems are the basis of all my speaker design. They provide accurate sound reproduction, a compact size, and excellent value for money.
8"2-Way
This is the smallest system which is a design dated back to 2007. It is based on an excellent 200 mm (8") neodymium magnet woofer of European origin possessing a very nice warm, musical sound. The cone material is treated paper. This high efficiency woofer (94 db/ watt) is capable of handling 200 watts music.
The first generation 8"2-Way was a medium size design sold with a stand. I made a larger, floor standing version in 2009 wiith a bigger 200 mm (8") horn.
The 8"2-Way C was created in 2016: a three piece design consisting of a bass module, a midrange module, and a base. The horn size was increased to 260 mm (9.85").
I made another version, the 8"2-Way N in 2018 by incorporating the cabinet design of the 3-way system. It has the same specifications as the 8"2-Way C.
The 8"2-Way A is my first active speaker. It has an internal 60 watts transistor amplifier to offer compact size and beauty while retaining all the sonic quality of the design.
8"2-Way C specifications: (Al & Be)
