110 Watt VHF Radio Speaker Considerations

I currently have a 110 Watt Kenwood in the chase truck with a Kenwood speaker and I’m going to add a second 110 Watt Kenwood to the truck (the second radio isn’t coming with a speaker).

Is there anything I need to know about speakers and VHF? Is there anything special inside the Kenwood speaker that works better with VHF that wouldn’t be found in a normal stereo speaker?

Thanks,
Mike

I'm no radio expert, but I don't think so, as I have been using a pair of no-name freebie computer/stereo speakers for several years on both a UHF and VHF radio.

I don't think the frequency at which a radio transmits/receive has any impact on speaker output.

Probably be best to match speaker impedance, but I didn't.

Good luck!

Thanks for the reply. I was actually hoping to be able to use much smaller computer speakers for both radios.

+1. RX/TX in any frequency does not matter in terms of what speaker to use. Use whatever speaker to you want.

You can fry a Kenwood hooking up speakers incorrectly. Download the service manual.

The link above is really just two small pages. Based on the 790 documentation it reads like there's a max 3 or 13 Watt speaker output depending on setup.

Should be good for most speakers, no?

I'm not concerned about how to hook up the speaker (I have the documentation for wiring a speaker), I was just wondering if there's any magic in the Kenwood speaker hardware vs an ordinary speaker in terms of VHF communication fidelity. (This isn't mentioned in the documentation I have)

I'd really like to switch to a smaller physical size speaker if I can. The Kenwood speaker takes up a lot of room, and I'd rather not add a second one that size.

Gotcha. Any speaker within spec should be just fine. I'd be curious to know what you ended up going with and how it works out as I set a lot of these up but always just stick with the KES speakers.

The thing with the speaker is to make sure it is 4 ohms and at least 15 - 20 watts Capable. If you run anything other then that you run the risk of burning out the amplfier for the audio output. The Kenwood KES-5 and KES-4 are really durable speakers. The issue with computer speakers is, they were never ment to take the vibration of an off road vehicle or the dust/dirt from off roading.

Also, if you get anything less capable of handling 20 watts, the sound will tend to distort. Year's ago I tried running the small little external speaks to save space and they sounded pretty bad. They were only 5 watt capable. Live and learn.
