  • For what it's worth, I used "standard" eyeglass micro-screws and the thread seemed to work well. Added a tiny drop of threadlocker just in case, but I'm sure i didn't need to.

  • Ahh sweet, PoE. This is legendary.

  • I second this question. I just received my pair today, they sound pretty good pressed against cardboard with my finger, but the thread size would be really helpful for a more permanent installation.

  • This is awesome. Would also be really cool vertically aligned.

  • Any possibility of getting a photo of the connector?

  • That'll likely take some serious experimentation, as each one should have its own isolated 'cone' for optimal output, but that's a great idea!

  • The same datasheet seems to cover both of these relays, and everything matches. I don't see what problem you are running into, rsp.

  • Doing a comparison between these and what I've used would be somewhat difficult. Mine are (basically) attached to the joists in my crawlspace and I feed them sine waves at certain frequencies as a "whole-house capable" alert system - 25 watts is good for that; without knowing the specs for these, I'd be hesitant for fear of over-driving them.
    But if you want a stand-alone review, I'd be ok with that; though I've never done such a thing before, and am sure there's others out there that are more capable and certainly more worthy.

  • Awesome, thanks for the clarification on these details, Robert (I was hoping you'd chime in anyways).
    The 25 watt exciters I have are also very solidly built, mine also have metal enclosures and steel suspension, and actually look very comparable in quality to these that you offer. And you're right, there's a huge price range overall for exciters/transducers - just as there are for "normal" speakers.
    However, at $20 a pop, these are priced out of the "experimenters" range, given that they have such low power capability. After 6 months, my $6 units still perform solidly.
    Maybe if I can scrounge up $20 I'll buy one of these to compare.

  • Good points, but they don't explain the price, you're simply describing the technology. (In fact, your point #2 is flawed, they do push against something - the resonating surface - as proven by the L-shaped attaching arms as seen in the photo).
    6 months ago, I bought 4 25-watt surface exciters (with roughly similar physical dimensions to these) for about $6 each. The $6 price tag was not a sale price. Looking elsewhere on the net at this moment, one can find many similar units in the same price range. This isn't new technology, there's no justification for the price listed here, unless there's some super-duper features not listed.
