Editor Review : JL Audio CP108LG-W3v3 Compact Ported Bass Enclosure
In all fields of the loudspeaker makers’ Dark Art, there exists The Magic Box.
This, like some mystical acoustic alchemy is the perfect marriage of a particular transducer and its wooden soul mate. A combination that somehow transcends mere computer programming and theoretical piffle and presents a real-world moment of wonderment.
This PowerWedge box is one such Magic Box. With the eight inch W3 woofer in there, it is somehow bloody incredible! Bass with edges and stops and starts. Bass that’s melodic and tight with the ability to track wobbles within bass lines and real sudden increases in dynamics and power of the lows. Bass that’s just bloody wonderful.
This is a medium power product and was married to the output of the JL Audio XD200/2 two channel amplifier. This sent a real 200W RMS to the subwoofer, well within its abilities and yet still able to make it wake up and ripple, throb, drop and purr.
It was on a mediumly powerful amp but so well balanced, I would say they were meant for each other. Like car shows and wannabe model contests, they are a perfect combination. But the sheer bonkers loveliness of the bass of this box is just hard to get your head around. Yes, you can get louder but you’ll usually get a bit of the bass passband that a woofer doesn’t like and tends to ‘˜boomp’ a bit at in nearly every bass system. This box has no ‘˜boomp’ zone it just plays it all, including the low and phat tones, with perfect control and weight, quite utterly belying its diminutive size. I also suggest it drops way below the stated 28Hz, even if at a reduced level.
For a ported enclosure it has a bizarrely wide passband.
If you get one and get it installed then don’t show your mates. When you ask them to guess between it being a ten or a twelve by ear, many will guess twelve. All will just marvel when you show them it’s an eight.
Bloody brilliant, bonkers, bodacious bass with badass bravura.
I quite liked it.
