Andre Marc has posted a review of the JL Audio Dominion d108 subwoofer ($799-$899) at Audio Video Revolution. His conclusions:
“The Dominion subs, once dialed in, essentially disappeared and ended up being indispensable additions to my system. When they were turned off, it was quite noticeable. Noticeable to the point that I feel my system is better of with them. Here is a huge bonus: if excellent sonic performance was not enough, Dominion subwoofers are made right here in the USA in JL Audio’s Florida factory.”
