Anyone using the visaton FRS7 speaker?

The Leopard is an easy case. I have a Torro metal chassis for the Leo. Both the original HL and the Torro (picture2) have lots of open space in the chassis because the canon mechanism and BB shooting are all confided in the turret above the chassis.

The HL Abrams turret is a totally different story. The canon mechanism and BB shooting are pretruding 3/4" below the turret. Any speaker box thicker than the original HL speaker will interfere with the turret rotation.

I spent 2 days rearranged the Abrams chassis, including removing the battery box upfront. I finally gave up and reinstalled the HL speaker.

Yea the abrams is out of the question for me too. The tanks I have where I’m planning to upgrade the audio are

t72 (impossible to do)
merkava
panzer 4 (?)
panther g (?)

I may get back to the Abrams for the 2.5" speaker upgrade. The HL 1" speaker has a peak at the lower midrange, making the gas turbine sound exaggerated and somewhat unrealistic. I will have to replace the HL elevation/recoil unit with a servo one like this:

The servo barrel recoil unit is much more compact than the HL trigger motor unit.

That’s actually brilliant. You’re using the 7.1 on the Abrams? Will that same unit work with the 7.0?

The TK-7.1 MFU has 4 servo inputs and the Abrams needs 2 for the barrel recoil and canon elevation. The TK-7.1 MFU is more expensive than the TK-7.0 MFU, but otherwise functions the same. The servo metal elevation/recoil unit is not cheap either. It may be a while before I get to this 7.1 upgrade for Abrams.

Ahh I understand. Well, not that it’s going to make a huge difference after I place the upper hull over the speaker but I have a TPA3110 15w amp I’m going to try on the dayton speaker with a 1000 uF capacitor on the power input lines of the amp. I will share my results with a before and after video. Just experimenting.

Do you use the DKLM loudspeaker? A picture of your RC tank chassis will be much appreciated.

No the speaker is not from DKLM. Cheaper to buy direct from Visaton, and build a speaker box. The simple solution to gaining space, is to remove the battery box.


I have also see where the battery box has been made smaller, and used to contain the speaker.

Did you do anything about the canon mechanism and BB shooting unit pretruding from the turret?

Sorry for the late response. As I do not use the BB shooting, it is simply cut off below the elevation tracks.
