I first heard of passive radiators decades ago, but to use in place of a speaker, rather than a port. Currently I'm seeing a trend toward mounting a tunable passive radiator instead of using a round, square, or tube port in a speaker enclosure. Has anyone actually tried one of these alternatives in a sound system? www.centerpointaudio.com/passiveradiators.aspx |

My Klipsch Fortes have passive radiators. I love them.

I've never heard of passive radiators used in place of a speaker. When I worked for RadioShack, 'way back in the day, we sold speakers that had them in place of tuned ports. Here is a page from the 1982 catalog: www.radioshackcatalogs.com/html/1982/h024.html |

Yep back in the day had two Canon Trans-linear speakers; 10 inch woofers, small mid range speaker smaller tweeter. They had passive woofers in the back. Great sounding speakers when placed so the Bass coming from the back had room to resonate. Weighed a ton though.

I think both passive radiators and ported enclosures, (both using the same basic principle) have their use depending upon the listener's expectations.
They don't "replace" a woofer though, they are an alternative to a port.
I still like sealed speaker enclosures the best, but I do own a few sets of ported.
Some are front port, some rear, some dual port.
Each has their strengths and weaknesses, so depending upon your system, your listening preferences, the listening room, the music listened to, and the particular speaker employing such choice...well you make your choice and live with the varied results, as it is with all audio equipment as none of it is ideal, but if you can strike a balance to your needs, well you're golden.
I have a set of rare Pioneer Elite TZ9 speakers, twin front ported towers, what is different is they have one front and one rear 10" woofer joined physically by a large bar. They also have a front firing ceramic graphite dome mid and tweeter. Those 2 drivers "float" on an isolated panel as does the crossover. They weigh 145 pounds each!
Admittedly although they have a sound not for everyone, for me they really play amazingly clean, fast, and overall even handed in overall tonal balance.
But....
They are VERY fussy with associated equipment and love tons of power. I run 2 heavily modded 300 watt each Adcom GFA 565 mono block amps to feed these hungry monsters. Folks that hear that system are shocked at the immediacy, the clean, well balanced presentation they deliver.
