New heng long t90 sound stopped

[Woohoo\o/]

Hi commanders, I understand not all tanks are perfect but after about 4 runs the audio started making a strange grinding type noise then all audio cut out.

I tried restoring the settings, I unplugged the speaker and checked for any voltage coming from its corresponding plug. Nothing.

I also swapped batteries from another tank. No success. do you guys think motion will warrant the issue? Its 5 days old

[Abyssus]

Speaker blew most likely, the 7.0 boards are terrible for that.

[Evan D]

Motion is pretty good so you should ask. But, what are you going to ask for, a speaker?

[Woohoo\o/]

I guess. If it's the speaker hopefully they will send a replacement. Or maybe I can get a speaker from a bluetooth speaker box I have here?

[Evan D]

Get a proper replacement. Do your homework and ask for the proper item. They show them under the parts tab for your tank. It’s probably this but double check.

My speaker is half that size but I see what you mean. Either way for testing purposes I'm going to salvage one of those speakers from the bluetooth box. Shouldnt I be recieving voltage from the speaker socket on the board?

[Evan D]

Yes AC voltage. But be careful as you can ruin the control box testing. You never said what tank you have.

Well I swapped to another speaker and it worked. Not as loud as the original but doable. So arent Their any aftermarket speakers that could replace the stock with better performance?

[Evan D]

Sorry, I don't know.

[Woohoo\o/]

Even this replacement speaker is sounding like its giving up lol time to find a quality speaker. No worries evan thank you kindly. I'll be sure to link a good speaker when I find one.

I bought a decent speaker from these folks:

https://dakrctank.com

they are under their electronics drop down menu.

That said, I have very poor hearing and use hearing aids. So, what sounds acceptable to me may not cut it for those with better hearing!

I second that! I got some of these Visaton speakers from Kenny at Dakrctank. I am very happy with them.

So the stock speaker that came with my heng long t90 is a 4 ohm 3w 2 inch speaker.

The speaker that I removed from a bluetooth speaker box was a 2 ohm 3w. the result was a lower weaker sound not to mention the speaker blew. LOL

so i ordered these on amazon. The t90 is very limited on space inside the tub due to its low profile design.

How well did those speakers work that you got from Amazon? Did you use both of them wired in series or parallel or just one?

[cmdrcody]

Well I ordered and installed the two MakerHawk 4 ohm 3watt speakers I got through Amazon in my T90 with the TK-7.0 board. I trimmed off the two mounting tabs on each one, hot glued them together, wired them in series and hot glued them in place at the rear. They are louder on full volume than the OEM speaker that came with the tank. The low profile of the speakers was excellent for clearing the wiring harness & turret rotation. I'll keep you all informed how they hold up under constant full volume applied.
