New CSS Passive Radiators Now Available

Creative Sound Solutions has just announced a new line of large displacement passive radiators. CSS is well known for their wide and full range drivers (the WR125 and FR125, respectively) and has recently been expanding their offerings into the subwoofer world, including the SDX15 and SD12. Now CSS is offering passive radiators to support their subwoofer lines.

There are many advantages in using a passive radiator. Most notably, you get the effect of a bass-reflex enclosure without pipe resonance, air turbulence, and the ability to tune to much lower frequencies without using ports that are a mile long.


Large displacement passive radiators have been tough to find since Adire Audio and Stryke Audio quit offering them commercially. TC Sounds had a small quantity available as well, but now CSS seems poised to offer a high quality passive radiator at an affordable price. The PR1816 is priced at US$129 (C$136) and the PR1821 is priced at US$139 (C$146). Shipping is an additional cost.

Built by John Janowitz of Acoustic-Elegance (formerly Stryke Audio), CSS is offering two models, the mass of which can be changed by adding mass to the rear, supporting up to 2500 grams.
