Product Details

Tectonic Elements TEAX25C05-4 25mm Classic Exciter 4 Ohm

Tectonic Elements 25 mm TEAX25C05-4 turns virtually any surface into a high fidelity loudspeaker. This exciter's small size enables audio reproduction in places never imagined: toys, monitors, cabinet doors... even windows!

The TEAX25C05-4 exciter employs a neodymium magnet for maximum magnetic flux around the voice coil and increased sensitivity. In turn, this reduces power requirements making it possible to use very small audio amplifiers without sacrificing total output.

To ensure maximum acoustic energy transfer between the transducer and the surface to which it is attached, 3M adhesive is affixed to the mounting ring. Two terminals extend from the exciter for wire soldering purposes.

Note: An exciter's frequency response and sensitivity are completely dependent on the exciter's designated surface. Thinner, smaller materials will tend to be louder and create a mid/tweeter response. Thicker, larger materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.

Specifications: • Power handling: 5 watts RMS, 10 watts peak • VCdia: 25.4 mm • Nominal impedance: 4 ohms • Dimensions: 1.75" dia. (2" including terminals) x 0.563" H • Weight: 83 grams.

Tectonic Elements TEAX25C05-4 25mm Classic Exciter 4 Ohm
Tectonic Elements TEAX25C05-4 25mm Classic Exciter 4 Ohm is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from What a kick in the butt...I bought 2 of these with a 2 channel 10 watt amp and can't believe what fun these little buggers are. When I first connected then to the amp and turned on the power there was no sound I then picked one up and held it to an empty box and WOW it blew me away and the sound quality was very good also, you have to experament with different objects for sound Hi's/lows but what a great product for the price I spent half the day just sticking em on things the only downside is the two sided glue doe's not last long.

Hi, I see this item is on clearance. I use it for a school project (make any surface into a speaker). Can you tell me which of your items will replace this? Also, what other exciter/s might be driven by a low output op amp, such as an LM386 IC?

Asked by: miclem
The closest option for this would be the Dayton in the link below. This is also 4 ohm and will be driver easily with that amp.

What do I need to do to drive this as loud as possible from a tablet computer headphone out of 32ohms?

Asked by: updi
Any small amplifier rated for 4 watts or more will do the trick. You might consider something like the Lepai TA 2020+ which will have more than enough power but is a small form factor at a great price.

I want to use these speakers to create a portable box. What kind of battery can I use to power them?

I am looking for something small and light that would be able to power these speakers about at least a few hours. Thank you.
Asked by: alex t
In order to choose the right battery, you would first need to choose an amplifier. We have many amplifiers that would be suitable for this kind of application, I've linked a few below for your convenience. Any of these would run on 12VDC power, I've also linked a 12V SLA battery below to get you started.
