The driver selection was much easier than determining the enclosure design. I consider myself an audiophile, so the drivers had to be accurate. I selected the Hi-Vi TN28 fabric dome tweeter because it offered accurate sound reproduction combined with styling that would allow me to imitate (and therefore fl atter) the B&W 805S design. The sound pressure level (SPL) vs. frequency response graph published by Hi-Vi indicated that the TN28 was relatively fl at from 2 kHz to 20 kHz, producing approximately 88 dB.

I used the tweeter's 88 dB SPL as a guide for selecting a 6" midbass, and quickly identifi ed the Hi-Vi M6N as an excellent candidate. Since this was my fi rst speaker design project in many years and easily the most complex, I decided to purchase a Dayton TITSK-10K Titanic MKIII subwoofer kit. Assembly of the kit took about two hours and the subwoofer sounds fantastic. I would highly recommend simplifying any surround system design by adding the Dayton subwoofer kit!
