    Weighs 1.75-lbs”

    Yeah. Lemme tell ya something: with bracket attached, it’s half the weight of a six-pack.

    I’ve read reviews from all over and not seen anything but praise. Few pieces of gear get “universal” approval.

    It may matter what radio is driving this speaker, but one can’t help but be impressed by rough-use government service accolades where intelligibility is crucial, and exterior conditions are difficult.

    I’ve an armload of typical external speakers from CB retailers (Cobra and Uniden) with which I’ve been satisfied, but they’re all going to new homes.

    Prior to the use of DSP-equipped mobile speakers, I’ve wanted a solid back-up radio rig — every component — for five (5) family locations; vehicle & house. This speaker atop that list. Found a nice deal on a lot of five (5) out of Houston.

    Did a search here which didn’t show a specific thread about this speaker. Some comments scattered around. Thought I’d get one going to ask:

    Where’d you mount this heavy so-and-so?

    I did find this to make an easy adapter to a CB/Export.

    Cerrxian 3.5mm Mono Male to Two-Pin Screw ($7.00)

    1). Solid black wire = Ground
    2). White stripe wire = “Audio”

    Audio leads (light-gauge, non-shielded) look to be three-feet (3’).

    A 70V 8-ohm to 4-ohm transformer (I don’t expect to have to use; but that would drive my total to a whopping $27/speaker).

    The radios I’m looking to use this with are 2.5-3.0W 10% THD with an 8-ohm load. I’m guessing (hoping) it won’t take 1W to drive this in a mobile. The Kenwoods appear to be 4W/10% at 4-ohms.

    I use two KES-5 speakers in series on my 7300 at the base. My radio buddy turned me on to them. They are great sounding speakers and built like a tank.

    Found a copy of the instruction sheet to add info I missed in first post:

    40W, maximum input power
    20W, rated input power

    (Dimensions are 5x5x3)


    Doesn’t look hard to add an 18W KEMO MO33N amp (if desired).

    Amp above, schematic below

    25D13D5D-7B0C-4099-94C9-AFAF1ABCDF4A.jpeg


    And, a less expensive RS transformer

    Maybe I’d be creating a helluva noise problem, but what’s a loudspeaker without being LOUD?

    Save the battery on a wireless mic until needed? Looks like one could do this (power off remotely) on a UNIDEN Bearcat 906 wireless microphone (while still in range).

    Etc

    (The pair above at $30).

    I’d imagine the speaker as used in public service vehicles is asked to be heard at some distance away. I haven’t looked at those radios to see what wattage being used for amplification.

    Maybe someone here knows this speaker in that use.

    (Yeah, I thought it’d been about a month since I was home now I see the dates above).

    The five orphans are lined up and staring at me. Decided on keeping four (4) of them. Sons and my vehicle plus our homes. Set to hang at a window being run by an amp that one can hear them however far they can project. Or run them “quiet” enclosed by house or car.

    I see these as adjunct to the WM DSP Speaker.

    I’m looking forward to those tests, but it’ll be “maybe” by Election Day on that.
