I recently acquired a set of Adire Audio HE 10.1s and decided to post up some of my observations on this particular DIY kit. I would describe these speakers has having a forward and musical sound. At first I was skeptical of the ability of a 10" 2-way speaker to play well in the mid-range, especcially since most 8" two-ways I've heard had lackluster mids so I assumed a 10" would be even worse. I was pleasantly surprised by the performance of this design though. The mids sound natural without any anamolies that I could detect. The most impressive aspect of these speakers was the soundstage they project. They project a very focused and realistic soundstage. Center imaging is rocksolid, I could have sworn there was sound coming out of my Paradigm center channel despite it not being hooked up. The HE 10.1s also have a respectable amount of bass output. Good enough to keep me happy with 2-channel use but a sub wouldn't be a bad idea. The bass is tight and musical. It did exhibit a certain "paper-like" quality that I only noticed extrememly off-axis. The highs were lively and detailed. They do seem to cut off sharply once you move off-axis but this point is pretty far out and allows a decently large sweet spot. Thanks for reading my impressions.
