You can dismiss it if you want, but I'm not sure how that benefits you.
Again, Accugroove is a company that sold a series capacitor as an impedance switcher. If you understand anything about electronics, that's either utter BS or extreme incompetence. They don't have a good track record at all for good design.
I'm not suggesting you dislike what you heard, you like what you like. Hey, I might like how it sounds if I heard it. But is it an accurate FRFR over a meaningfully usable range, no it's not.
Very interesting insights and all have merit! It would be interesting to hear AccuGroove's explanation for the design.
Me too... although I don't know how what I've pointed out can be discounted. It's not arguable, it's just facts.
The distance between two sound sources should be less than 1/4 wavelength of the sound it's producing in order for them to combine as a single sound source.
Let's say the Latte dual tweeters produce 4k ~ 20k Hz. Wavelength of 4 kHz is 3.4 inches, 1/4 of 3.4 is 0.85 inches. Are the center points of Latte dual tweeters 0.85 inches apart? No, looks more like 3 inches apart.
Since the two tweeters don't join up as a single sound source, their phase will not be in alignment in off axis, throughout the entirety of its frequency range, causing comb filtering.
Let's consider why they might've chosen dual tweeters.
1. Lack of tweeter volume? Probably not, cus tweeters are more efficient than woofers, but if so, just use more efficient tweeters.
2. Directivity? Put a waveguide on it instead of introducing comb filtering. Or at least put the tweeters closer together.
So what is up with this befuddling design? Well, let's look at the accuswitch... That's their track record.
3. Cus it looks cool, and more tweeters more better? Probably.
I can't tell you anything about the science... But a group of us including @iarsee did side by side comparisons listening from various locations within a very high end studio live room and they sounded great from any position except far to the sides or from behind (the same "issue" all would have).
Since they belong to my bassist, I also did additional comparisons at my house with my Xitones and they did not display any adverse issues.
I believe you! I would probably like their sound too. I'm not a speaker designer, I don't have the ear training to know how to listen for these inaccuracies. But I can inform myself as a consumer what's a good design and what's not. With all due respect, "sounds great to me" isn't the point of an FRFR, accuracy is.
Speaking of bassists, there's some legit informed speaker designers on bass forums like basstalk. Some of them have spoken out against the bad designs of Accugrooves. Just ask yourself, where else have you seen dual tweeters? On any other pro equipment where accuracy matters? Any studio monitor? PA? Anywhere other than consumer space where "it looks cool" and marketability reigns? There's a reason it's not done.
