Clark Synthesis TST239 Silver Tactile Transducer Bass Shaker
TST239 strange noise
I had some smoke coming out of this unit and now it is making strange noises along with shaking and cuts out every 2 minutes. Any suggestions?
Sounds like it's fried. If smoke came out then that probably means part of the voice coil overheated and burned. Did you use it at an extremely high volume when the smoke came out?Considering that it's still working, perhaps what happened is that part of the voice coil shorted out, resulting in a shorter voice coil, and this reduced the impedance. This might explain why it cuts out every once in a while and why it makes strange noises: if the impedance has been reduced by means of a voice coil short then the amp will be have a greater load than before, which could cause the amp to distort and/or cut out.It's hard to say much more without additional info. What is the DC resistance of the transducer right now? The nominal impedance is 4 ohms, which means the DC resistance when new would have been about 3 ohms, so if the DC resistance right now is less than that then you've got a partial short.In any case, you probably shouldn't use this transducer anymore considering the problems you're having. It could damage the amp.

I'd like to buy this TST 239. Do I need wireless remote for my TV to work with this device?
Also, do I need an amplifier? What is a basic one you would recommend?
this is like a simple speaker it needs an amp with volume control

2xTST239 + SPA250 wiring
Could someone please suggest wiring options for two of these with a 250 watt bass amp? Would impedance be a major factor? Thank you.
Upon having a look at both products' manuals, I can see that two tst239's in series need an 120-150 watt@ 8 ohm amp, and the spa250 is rated at 156 watts @ 8 ohms. So nominally it should be fine...

Best wiring and amp for the job?
I want to buy two of these Bass Shakers for two separate recliners that sit 2 feet apart. I was thinking that wiring them in series to present an 8 ohm load is the best way to go. Does it make any difference wiring in series at 8 ohms vs. parallel at 4 ohms, performance-wise? Also, which Dayton Audio plate amp is best suited, the SPA 250, or the SPA 500? I want solid performance with minimal/no risk of burning up the shakers.
I have never had a Clark to play with, contact PE Tech for this.
