There is a review of Adire's HE10.1.

Seems like I saw a reference to that review somewhere, but I don't recall where. Probably over at the High Efficiency forum, since that's really the only place I go besides here. Lately, I don't even have time for that.

So where is the Adire review on AudioXpress? I went there and looked around a bit just now and didn't find it. Do they publish online or only in print?

with the tweeter in the wrong phase, causing a large dip in response for the one speaker. I was very disappointed.

"the crossover was wired correctly as indicated by the red dot on the tweeter terminals. unfortunately, the terminals are mismarked. this is an adire error. a diy builder would have no way of knowing the tweeter was polarity-reversed." joe d'appolito
.
HOW DID THEY HOOK THE LEFT AND RIGHT TWEETERS IN DIFFERENT POLARITIES? Even if the red dots are backwards, one would assume that they both had the red dot on the same relative terminal, right? I think Joe is insulting the readers intelligence with his claim. And Dennis Colin rated the "image focus" a 9, the highest they rated any single category in the review:)

"Imaging good, very precise" d.colin

With the HF in reversed polarity?!? Sam

Interesting that they didn't seem to notice the difference in response from one speaker to the other. I use a lot of vintage speakers and the first thing I do when I hook them up is put a mono recording through them to see them and roll the balance to see if there is any difference in the FR. I also to a center image check as suggested by Dave and Dan at Adire. I would do the same if I had just built a speaker. It's easy to wire something out of phase even when it's properly marked. I was taught by my father who built his equipment in the early 50’s. He didn’t have any test equipment but he knew how use his ears to detect problems.

It's not surprising that the image focus is top notch. A coax tweeter that is phase aligned with the woofer should have excellent imaging.

I was not trying to suggest that the review showed that the Adire product is bad. I was recommending it just as an interesting read. Quite a comedy of errors! I quite enjoy the construction and theory articles in AudioXperss but they need a little work on their reviews.

Perhaps the misconnection made them sound more interesting?

One thing I noticed about the Adire is that the response seemed quite ragged even on the speaker that was wired properly. I wonder what the deal is with their tweeter?
