Anyone using the visaton FRS7 speaker?

[Meter Rat]

I used 2mm plastic card, to make the speaker enclosure, in my Tamiya Leopard 1, which has torsion bars. The enclosure has cotton wool in it to aid sound.

Sweeet. I ordered one now the only thing I’m concerned about is fitting it into my leopard and Abrams. The tub now has torsion bars so I may need to get creative. Thanks keilau

In the original HL Leopard2A6 chassis with coil spring suspension, the battery compartment took up much of the space. It is difficult, if not impossible, to fit a 2.5" loudspeaker.

I added the 2.5" loadspeaker after I upgraded to the Torro all metal chassis. I use velcor to fix the components to the floor plate over the torsion bars.

As far as I know I can use styrene or wood. Maybe acrylic I don’t know. Did you have any trouble fitting yours in your tank? Assuming you have torsion bar suspension?

What do you use for speaker enclosure? A vented enclosure will help keep the efficiency high.

The worst mounting is an open back mounting. You lost the backside acoustic energy completely and effectively half the speaker efficiency. Without acoustic loading of the driver, the bass frequency rolls off too early that the diesel engine's low frequency rumbling is lost. The HL 1" speaker box will sound better than an 2.5" open mounted speaker.

Awesome. Question, did you use an amplifier? Or just plugged directly to MFU?

These 2.5" speaker comsume very little power. The MFU built-in amplifier is more than adequate for them. In fact, these 2.5", in either the DKLM or my home built vented enclosure, are more efficient than the HL 1". I actually turn down the volume using the radio. A vented loudspeaker box is the key.

DKLMRC.com market 2 speakers for RC tank using the visaton FRS7S driver. The S version indicated the full range version.

I built my own speaker using "Dayton Audio PC68-4 2-1/2" Full-Range Poly Cone Driver". It is cheaper and has a larger magnet.


p.s. DKLMRC is not shipping to US during the trade war.

p.s. Keep the speaker magnet away from the radio MFU to avoid interference.

I’m wondering anyone here is using the visaton FRS7 full range speaker. I want to up my game on the sound of my tanks particularly my leopard/abrams and merkava. They seem to have room. Will I need to use an amplifier? Or does it sound good without one? I won’t mind using an amp but I don’t know how to to wire it up. Any help is appreciated.
