New speaker box for the shack

[Bill-4]

I have decided to get away from the Behringer amplified speakers and
build a box with a Lanzar subwoofer (6.5 inch - 105 to 12k - 94 db
sensitivity - 8 Ohm) for HF and several 3" speakers for the assorted
VHF/scanners etc.. The box will be sealed and I may partition the
smaller speakers into their own compartment. For the smaller speakers, I
am looking at the 3" DROK (15W - 108 to 20k - 8 Ohm - 90db sensitivity)
- although I an not above using something cheaper (due to their planned
usage).

Nothing fancy for the entire project. The primary speaker will be
switched between the K3 and another rig, as needed. Both rigs are recent
and are loaded with EQs etc. If I run into a hiss problem, I should be
able to eliminate it by using a condenser or two across the inputs to
knock out offending highs.

The initial reason for the Behringers was to remove offending hiss,
which they do well. Now, I am looking for a simplier solution - with
less controls and less wires. Hence, a single speaker box for
everything. Needless to say, I do have a good shop. My K3 does not have
a second RX and never will. I rag chew - no DX or contesting.

I have avoided the metal box speakers from the various big names (IKY) -
too expensive for that they are and I do need matching anything.

Suggestions and comments would be most welcome.

Thanks,

Bill W2BLC

Here's an excellent small 2-way that I often specified for the sound
systems I designed.

In case the link gets mangled, it's an RCF MR55, and the link is to Full
Compass (Madison, WI) where I buy small audio products. It's a
family-run biz that I competed with 30+ years ago. RCF is an Italian
company.

This photo shows a row of them installed in the VIP Suite at
Northwestern University's Dyche Stadium (very high, white with white
mounting brackets). These are very accurate, very efficient
loudspeakers, which means that the K3 can drive them directly.

This stadium is in Evanston, IL, which can get chilly during football
season, so the VIP suite is fully enclosed. These are NOT paging or "PA"
speakers -- they are fed A/B stereo from a spaced pair of mics that
picks up the crowd, so that the VIPs feel that they're part of the
action. To accomplish the very natural sound of the crowd, these
speakers had to be very accurate.
