Audiomobile EVO 2408 D4 High-Performance 8" Subwoofer designed for Compact + IB Enclosures

"A passive radiator is a speaker without the magnet, and electronic structure attached to it; it is just the cone, suspension, and frame. It looks like a normal driver (speaker) from the front, but on the backside, it appears to have had all of its "guts" removed. So basically, subwoofer soft parts that's weighted + frame."
So whats the big deal with them & how can they help me deliver better performing audio systems?

Space in newer vehicles is becoming more and more scarce. From the under seat of trucks and compact trunks, customers are less open to giving up their valuable space. As we know from experience, traditional "shallow" subwoofers typically do not give customers the output and sound quality they are looking for. When you're dealing with air volumes smaller than 0.7 cuft, ported enclosures are not really practical due to port length, so most applications receive a sealed enclosure. But what if you could gain the output of a ported enclosure, not deal with complicated & long ports and not increase the airspace due to port displacement? Sounds like wishful thinking..... But this is exactly what passive radiators will provide you.

Take the chart on the right (below on mobile), a single 10" Audiomobile EVO series subwoofer which is 4" deep, real-world 500wrms power handling, and actually designed for small compact enclosures.

The Orange line is that subwoofer in a 0.5 cuft sealed enclosure (check out that low-end!!), then by just adding 0.1 cuft (Blue Line) and a passive radiator, you gain a massive boost in performance without taking up your precious space.

Make the impossible possible. The Audiomobile M-Car Passive Radiators are available in 8-Inch, 10-Inch and 12-inch versions.
