You would need to discinnect the existing tweeters in the speakers youre adding this to, not sure if the unit has a crossover inbuilt. If it does then just connect in parallel to existing input on speakers youre augmenting, if not then you will need some sort of crossover arrangement which could be as simple as a single capacitor in series with the unit
Still regret to this day selling my pair of Optimus Pro LX8 speakers 🙁
Personally, I would search for some DIY speakers that could utilize these. This might turn out to be an enjoyable project.
I used to sell these. I worked at Radio Shack in the 90s. As far quality goes, it’s not top stuff. That’s of course in the context of the time. We also sold books on speaker design. It included all the equations you needed to build a box tuned for that speaker. Those came with a spec sheet. That line came with a full set of different mids and woofers. I used to build those boxes in my bedroom after cutting the mdf to length outside. PVC ports and Radio Shack grill cloth + terminals.
A box tuned for that speaker? Isn’t that a self-contained unit that sits on top of a cabinet?
I love that it says “nationwide supermarket of sound”. I miss how weird Radio Shack was.
Now you just need the David Weems book on speaker building.
These were briefly super popular with audiophiles back in the 90s. Definitely worth a quick plug-and-listen session.
I think they sound really nice but do not have the output you’d get from a more conventional tweeter at a given power.
RS sold a line of speakers with these as the tweeters and, IIRC, 5" - 8’ woofers (depending on the model). I’ve heard the ones with the ~6" woofers and they sound very clean and clear, very nice for a bedroom system or nearfield listening.
