Introduction of T & M Loudspeakers
T & M loudspeakers is new. We want to concentrate on making high quality cabinets from hardwoods. We use Oakwood and we also make some cabinets from MDF and marine ply, but our first priority is to use solid woods. T & M is based in Hong Kong so we work closely with Mark Audio. We use all Mark Audio drivers because the quality and performance is excellent. Twin Audio is our amp business. We match our amplifiers with Mark Audio drivers and also use some of the designs from Mark Audio plans.
We will offer both finished speakers and cabinets as kits. We can build to order. Send us your plan or email your details. We can help you with the build. We supply speakers to all major locations.

This is a good example, one of my customer in Hong Kong tried to add Alpha Core Air-Core Inductor to CHR-70. From his experience, this AWG12, 0.27mH copper foil inductor can give great improvement to the performance of CHR-70 full range driver. Wider sound stage, better high range, sweeter mid range and deeper bass.
This is a baffle step correction circuit. He also has resistors in parallel with the inductor. Could you ask him what total value of resistance he is using?
Can you provide more information about baffle step correction circuit?
Are the resistors are wired in parallel or series with inductor?
Resistors are in parallel. There are a couple of calculators below which you can play with.
