    I hope this project went well for Eric, I didn't even see the post until today.

    That is a great idea.

    Reminds me of a speaker my dad had for a transistor radio -- at least 50 years old. Made voices stand out.

    Actually, this speaker totally sucks for voice! But it's sweet on CW. We've just overcome a snag with the label printing supplier, and full production should begin this weekend. I have some excellent child labor rounded up.

    Glad you're making them, Eric. How do I order the tunable version?

    Hi William.
    I'll get back to you once we have a version that's easily reproducible. Still in the R&D phase.

    I can't vouch for the particular product but I can say that the principle of a resonant speaker is great.

    If you haven't heard one in operation here's a video of a (crude and unoptimised) one I made

    Really brings out the signal. It's fiddly to operate as the speaker has to be a held a critical distance from the glass, but no doubt this item sorts this out.

    +1 for what WR2E asked. I like hearing CW tones around 700 hz, but I like this concept!
