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.

 

Specifications:

Driver complement: 

Woofer: 305 mm (12"), 101.6 mm (4") voice coil, ferrite magnet, treated paper cone

12" 3-Way V2

 

This is an improved version of V1. The main difference is the use of a beryllium diaphragm in the midrange compression driver and larger size horns. 

 

All specifications are the same as 12-3 Way V1 except the following:

Beryllium diaphragm in the midrange compression driver

Midrange horn size: 360 mm (14.17") diameter, proprietary contour

High frequency horn size: 273 mm (10.75 ") diameter, proprietary contour

 

12" 3-Way V3

 

This is a completely new speaker.

Driver complements:

Woofer: 305 mm (12"), alnico magnet, 76 mm voice coil (3"), treated paper cone

Midrange compression driver: 101.6 mm (4") beryllium diaphragm, alnico magnet, 50.8 mm (2") exit

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)

12" 2-Way Concentric (Al & Be)

​

A concentric driver has the acoustic center of the woofer and tweeter located at the same point to eliminate all the interference and distortions generated by separate drivers. The result is a life-like reproduction of the music. The very high efficiency of 96 db/watt means that a single ended triode 3.5 watts 2A3 amplifier can be used to driver it with ease.

Modular 3-way Speakers

We are offering several versions of bass, midrange and tweeter modules. A 3-way speaker can be built by stacking them up.This makes speaker building very flexible. Hobbyists with a tight budget can begin with the bass and midrange modules.The tweeter module can be added on later to complete the system. DIY audiophiles can use them to work together with the existing system.

Three grades of cable are also available to cater for all kind of budget.

Bass Modules

There are four models using different size woofers ranging from 10" (25.4 cm) to 18" (46 cm).

The crossover for the midrange and tweeter are built into one unit which is mounted inside the midrange module.

Crossover networks are designed to integrate a specific pair of drivers, ie., a woofer with a midrange or a midrange with a tweeter. As drivers have different specifications, the crossover is not interchangeable. Be sure to select the correct crossover for the drivers when building the speaker.
