Energy 22 Reference with Sound Dynamics tweeters. Canadian hybrids.
I told you I had an idea, but I wasn't the first. When I told the guy I bought the Energys from what I planned to do, he told be it would work well, because he'd tried it. The tweeters come from Sound Dynamics (made by API, like Energy), and were used in 2 way systems with woofers as large as 15 inches. This told me that the tweeters must be capable of being crossed over low, an important thing to consider when replacing a hyperdome.
The system sounds fantastic, exceeding my expectations. I've been enjoying them with all kinds of music, from delicate to very heavy.
