~5 1/4" Passive Radiator Pair

[speaker]

~5 1/4" passive radiator pair. They have coploymer cones and butyl-rubber (not foam) surrounds. They are dusty from storage not dried out. The frames are pressed steel. They are very high quality.

They have not been mass-loaded so they can be tuned exactly to the resonant frequency needed for your project. I used Mor-Tite (plumber's putty weighed on a gram scale). You can also use RTV or lead shot glued into place.

These are extras from a mini-monitor project w/ a 5 1/4" woofer. You could also use them with a smaller driver.

I have several unused pairs of them.

$25 / pair + $5 for USPS priority in US48.

Money order only for payment.
