I thought first about an MTM design with 5" or 6" midbasses,
and a decent tweeter. Since I wasn't looking for
any typical teenage low-end, my woofer selection was
basically anything Parts Express carried. I have used
Peerless, Dayton, and many other woofers before and
was familiar with their sound, but I wanted something
new. Hi-Vi was next on my list; I had heard a lot of good
feedback about their products from my time on the
phones as a tech at PE. Based on my experience actually
hearing the F5 drivers in a setup a few months back, I
decided they would do the job for bass/midrange. Right
about the time I started the crossover design, I wandered
through the Project Showcase and came across Vince's
VHT system. The standard D'Appolito design I originally
thought of just got a little more complicated.
I had two reasons for selecting the Hi-Vi D8G as the
woofer: first, the surround on the D8G looks a little more
treated and potentially more immune to dry-rot than its
brother, the D8.8, and second, the overall appearance
would be a lot better with all yellow cones complementing
the cherry vinyl I was planning to use.
The last driver to choose was the tweeter. I needed
something that had a relatively low Fs but would maintain
a high efficiency (around 92-93 dB). The Vifa DX25TG-
05-04 was pretty intimidating at first glance, and after
consulting with Darren Kuzma, I decided to try the
XT25TG30-04 instead. With an Fs around 500Hz and a
91.5 dB sensitivity, it looked very suitable-and best of
all, I hadn't used it before.
