Don't pass this one up
I wasn't sure what to expect, but this passive radiator completely transformed my speaker build. The bass is noticeably deeper, tighter, and hits way harder without sounding muddy. It adds a surprising amount of low-end for its size, and you can actually feel the difference. Build quality is excellent, installation was simple, and it's been performing flawlessly. If you're building or upgrading a speaker and want bigger, cleaner bass, this passive radiator is absolutely worth it.

I built a small .35 cu ft box + displacement for an 8" Polk MM840 DVC sub. I stuck with the manufacturer's sealed box recommendations and added this passive radiator. The lows are awesome, the tone is phenomenal, I am shocked by how good it sounds for one small 8" sub on about 300 watts of power.

perfect for diy bluetooth speaker box builds that utilize a dedicated subwoofer
A bit pricey but it definitely gets the job done with a sealed enclosure. I use these for diy bluetooth speaker box builds that have a dedicated subwoofer.
