already the treble response on the r7 was quite rolled off than most speakers in its price class, additionally the tweeter sits quite low below ear level to make it worse.
Now let’s add more bass to make it worse. Yeah if the type of sound someone likes is the kind of of a boombox, yes Two KF 92s will do it right !
Yeah but is not like all kind of music sounds good with neutral top-end FR treble..., can you imagine HipHop / Rap music sound more plesant with neutral treble? it might will sound kind of boring and very harsh.
I have EQ the treble and it's sound fine, but thats because i want a neutral treble not everyone want the same FR. Also because the UNIQ it's point source it's vertical dispersion performance is very good, so the '' height '' is not that important as it looks like.
That's being said, as far as i know/remember you didn't have any problem with the bass from ur 7k, and the r7 gives the same kind of bass until die. ( 105dB both towers ) the R11 by other hand can handle more sub bass than both of these at higher spl due to it's 4 woofers. But in my small room i got a bass like a ref5 can do in normal rooms (of course, much bigger room than mine), only because i got some nice bass reinforcement in my room..
But remember, not all rooms can give you bass-gain, most of the room do the opposite...
My plan is getting 2 KF92, because if i move into a bigger room i will not get anywhere near the bass performance of this room.., and the bass performance is very important to me. I find fun playing some games in my R7s too and listening music with lots of bass.
And i'm pretty sure if i let the r7 play 80hz-20khz it will sound better, the IMD in the woofer area should be better (like any speaker).
