Aperion Audio Aluminum Ribbon Super Tweeter Speaker MKII

Now you're beginning to discover what being an audiophile is all about. Those Wharfedales have major directivity errors at their crossover point, between 2kHz-3kHz, due to the beam size difference between the tweeter & the woofer. Those speakers will not work well on hard floors nor low-ceiling rooms, both combined make the error much worse without major room absorption. Their sound quality due to that directivity error is totally dependent on the room, and to make the speaker sound good requires EQ between 2kHz-3kHz. This Super Tweeter will not help this particular 2kHz-3kHz Wharfedale error since the Super Tweeter output starts at 8kHz, although it might fix other Wharfedale issues above 8kHz. So while you can find maybe 6 pair (looking at Crutch.) of bi-ampable bookshelf speakers at under $700 MSRP, they aren't audiophile enough to not require EQ for the woofer/tweeter crossover or have other similar issues, and thus wouldn't be a consideration for the average target market of the Super Tweeter, audiophiles. Now, that doesn't mean someone using Wharfedale Diamond 12.0, 12.1, or 12.2 couldn't buy the Super Tweeters, of course they could if they just wanted those speakers to sound better from 8kHz-40kHz--it just isn't very likely. Like I said, you'll find Super Tweeters more likely used on speakers from $1,200/pair & up, but you retain that right to put them on sub-$100 speakers if you desire.

Wharfedale alone has 3 different models on their books right now at way less than 700 per pair, at MSRP. You would be far better off just finding a speaker that you like the treble on than trying to integrate a pair of super tweeters. The potential issues around directivity, imaging, and other interactions that you might have to deal with just seems like a wonderful way to waste a lot of time and money that could be spent more productively. That's before you even get into the silliness of a tweeter that extends to 40Khz.

Bi-ampable "New model" as in recently released at the MSRP, yes, some people like to wait for sales. But at least you got my point that these tweeters aren't likely to be used on cheap speakers that aren't audiophile-quality in the first place. Also, "Hate" was just the extreme example, someone can "like" their current tweeters, but just desire to improve the top end slightly by changing the tweeters, to go perhaps from their 90% ideal sound to 99% ideal.
