Comments/Description

A replacement for the no longer manufactured DAEX32. Good sound, can kick out a good amount of sound. Fairly heavy, so needs to be on a larger resonant object if you do not want to have too much dampening.

Originally designed for car stereos.

The transducer consists of two parts - the transducer itself and a plastic mounting or "coupler" ring which the transducer screws into. For set ups that require transporting, breakdown, etc. this works well, as you don't risk damaging the exciter when taking it off. The screw threads are relatively fine (compared to the DAEX32) and sometimes require some fiddling and pressure to get the threads to lock. The coupler ring has VHB coating attached - however, with mounting & unmounting the exciter, the torque can displace the coating. An easy solution is to remove the coating and use 3M VHB Tape.

This exciter has a "dual steel spring" design: two thin steel flanges which allow the transducer to vibrate strongly while still being firmly mounted. (Replaces the single spring design of the DAEX32). Exciters with spring design are less likely to break when being driven at higher volumes.

The terminal connections are designed to accept female-type crimp terminal connects.

Things to be aware of:

• The springs are quite thin, so can cut your fingers when mounting or unmounting - it is better to hold the exciter on the plastic screw sheathing when attaching or removing.

• The terminals are mounted into a plastic extenstions at the bottom of the exciter, and can become loose with attaching and reattaching terminal connects. If the exciter is going to be used for mobile or portable setups where wires are regularly connected & disconnect, it is recommended create an alternative connection possibility to alleviate stress on this part of the exciter. (See below.)

• If a buzzing sound occurs, the exciter may need to be tightened on the coupling ring.

Matching Equipment

Can pair with any appropriately powered amp.

4 Ohm version: While lower powered amps such as the Pyle Pro PCA3 can work for shorter periods, lower powered amps can heat up the exciter, especially at higher volumes. The Indeed TDA7498E has paired well with it.

Uses

Excellent for large metal sheets as well as larger (20"+) gongs and cymbals.

Alterations/Hacking

Soldering wires directly to the terminal connects, with the addition of heat-shrink tubing alleviates pressure on the terminals when attaching and reattaching speaker wires. More details on this to be uploaded soon.

Comparisons

The Tectonic Elements TEAX32C30-4/B is equivalent in size and weight, though slightly less powered, at 30W 4Ohms. The Tectonics doesn't have the terminal weakness or smaller coupler ring thread issues. Sound is roughly equivalent, though the Dayton a bit cleaner in the upper mid- and high-ranges.

Cost

$18.85, $16.60 for 4 or more (both types) as of May 4, 2016.
