Klipsch K Horns (the new AK6)

Reminds me of some other speakers I owned for years and loved. Tannoy’s.  They also don’t measure well which is why they spec the frequency response at -6 DB. 
 Measurements definitely don’t tell the whole story. And as far as Bass goes quality means a lot and horn loaded bass is definitely better quality then ported.  If I was buying a pair of these I would go into it knowing that I had to add subs crossed over at around 60 or 80 Hz, preferably horn loaded. 
 In fact at this point in the game I really wouldn’t run any speakers without subs. 

Mijostyn why would I want to throw all that expense and musicality saping electronics into a speaker trying to correct it,s flaws, that at 15k it should have. Now that,s being totally i*****c !

No George, The K horn has certain advantages the big one being efficiency which is the major reason it became so popular in the first place. It does have problems that have been insurmountable for decades but now they are not. So, why not try and correct them and see what you get? Many digital electronics leave absolutely no fingerprint on the signal and once you are in the digital domain you can do all sorts of stuff without any distortion, none. I can go in and out of 24/192 all day long and you will never hear the difference. You can not have the best subwoofer system without a digital cross over. You can not make your speaker image pristinely or accurately control your systems frequency response without full range digital room control. Without the ability to manipulate your system digitally you are in the stone age. Most of the recordings you are listening are either digital or were modified digitally. Any vinyl re release of an old analog recording that magically has no tape hiss, how do you think that happened? So if I use that tech to make an old speaker that magically plays loud as hell with a 300B amp image correctly what is the big deal.
This hobby is supposed to be fun and it is always fun to consider possibilities. That is how we advance the art.
 I’m starting to sound like Socrates.

No idea, no mater how much extra $$$$$$ anyone throws at them with correction electronics, you not going to be able to correct all those flaws, you can't make a silk purse out of a sows ear.
