Studying the 4t4

While at Axpona, I had enough time to discuss the speaker design and goals with Neil. I have started to understand the Mass Loaded Transmission Line speakers better. I do not understand the math, so I will not delve too deep into that. The goal and the result are a smaller speaker with better low-bass response and a very smooth and detailed midrange.

Cutting the cabinets on a CNC machine allows for much greater precision in construction, ensuring that the transmission line is “perfect”. The design uses 4in drivers that have very low moving mass to improve mid-range performance.

The series crossover is adaptable to many levels of performance. With the help of Neil and a local expert on crossovers, I have selected and optimized a set of components that should be a “BEST++” with just a bit more expense. I use Duelund bypass capacitors and a Duelund resistor in the tweeter circuit. Goertz flat copper wound inductors are a bit more expensive, but I am sure they will be worth it. My internal wiring will come from Reality Cables.

All of the internal components will be cryo-treated and demagnetized. I was “ordered” to purchase a specific Sn/Cu solder as it sounds the best. Yes solder! As of writing this, I have not found the right binding posts for the speakers. I am also working on selecting the outriggers for the speakers.

Construction will not start for a while due to work and family projects.
