Haven't heard the Beethovens myself. But, the reasons I think you'll love the GT's (Gen. 2 or SE) are because the entire presentation is uncommonly uncompromised, i.e. there seems to be no significant gaps or holes within it. (My quickie review here). They are neutrally transparent and will pass on whatever your components are doing exceptionally well.
The 2 drivers are well matched in that the woofer's phase response is mild and smooth and it hands over to a tweeter's phase response that is quite literally "ruler flat" over the entire operating range of the tweeter (you can find the response graphs of the tweeter at Dayton Audio's website). And some listening time will reveal that the very minimalist crossovers and the Mihorns are, in all likelihood, doing very little indeed to interfere with that unusually good, combined phase response. That results in a strikingly stable, complete, unperturbed and perfectly symmetrical soundstage. Simply not the norm, IME. The Mihorns can also easily be used to create a rather vividly 3D central image as well. Excellent spatial qualities.
I won't get into the details about "how" right now, but the Mihorns tend to "speed up" the sound of everything upstream from them. By that I mean that I'm using some amps at the moment that don't exactly have "HiFi pedigree" written all over them, yet the subjective sensation of system speed is as though I'd spent much more coin on them than I did...I'm still running some experiments along those lines, but I may be able to draw a conclusion or two about how they manage that trick a little later on. If your components are already top notch in that regard, then the Mihorns possibly may not accelerate much beyond a certain point, but, that they do so at all, I've found to be rather unique, so far, IME. Maybe other horns are known to do this??
But, tonally, harmonically and texturally revealing?? Oh yeah!! In spades. And very dynamic.
Look at it this way. They are very small and not only easy to place in the room, but easy and inexpensive to return if you don't like...but, I'll bet you won't return, at all.
Oh, I'll continue to listen to other speakers whenever I get the chance, just out of curiosity, but, even though I'm using a good pair of subs with them that only helps to seal it for me, I already know these are the last speakers I'll ever need to buy, period.
Can't really speak directly to the Beethovens (After_hrs may well be right about them), but I'll throw in my recommendation for the GT's, along with him, without reservation!
