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.

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.

Great for me but not for everyone
Used to add extra thump in a small enclosure for a 8” ct sounds 400rms sub. Definitely worth every penny if space is an issue. Keep in mind these are tuned in the 40s so don’t expect them to sound great on the lower notes, that’s what the 10 or 12 PR is for. I listen to all genres so it’s ok for me to sacrifice the lower notes under 35hz. A little pricey but we’ll worth it for the right scenario and setup.

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.
