side walls, custom time alighment and EQ, the "Wavelauncher" as Bill calls it is very much a plus,
not a minus.
He goes on to explain, “Modal adjustments at low frequencies can greatly improve the weight of a
system while eliminating ‘room boom’. Parametric amplitude correction assures that the left and
right loudspeakers appear nearly identical to the listener. Since imaging information is derived
from what can
be very subtle
left and right
differences,
small
corrections
can yield great
benefits in
restoring
realism and
depth.”
I’ll say. Here’s
how it works.
After he
uncrated the
speakers and
used my
handcart to
ferry them to
the listening
room where he
pretty much
just plunked
them down,
slightly towed
in. I always
physically measure the speaker’s distance from the back wall to make sure they are precisely the
same distance and toed in exactly the same on both sides. Then I sit and listen, make appropriate
changes, listen again and so on. Bill did none of that. He inserted the Wave Launcher between my
Purity Audio Reference Preamp (tube) and my rather ancient Halcro MC-20 power amp. It’s a 400
wpc Class D amp. The time of year was heading into summer in South Florida so I try to avoid large
masses of heat producing tubes when possible. My Qsonix music server was serving into my
Lampizator Level 4 DAC. It took some time to accomplish the setup because there are eight cables
(all XLR) that plug into the wave box. Then we had to run power cables, one for each speaker since
the built-in amps needed their own juice.
We set up a laboratory grade mic and plugged it into his laptop. For the next thirty minutes or so
the room was filled with white noise as he dialed in the correct values for my room. Then we
