I FIXED MY LISTENING FATIGUE !!!

I also run 2 way Klipschorn's using TAD TD-2002 from 450-24,000hz

If you need tone controls you have speakers that are not accurate

Tone controls are the MOST abused item in the hifi world !

Nope, made it a 2 way speaker.

I am not the first, maybe the first you have heard of, it is not the room, i have many other speakers none others do this. It is the speaker, the tweeter was about 5db louder and I have fixed it.

You think I would fake measurements ???

they did good with the forte 3, not perfect

when the tweeter is outputing over 5db more than the mid, that is bright !

The mid in the forte 3 was originally designed to play to 20khz (it was the tweeter in some of klipsch's cinema speakers) , none of the other heritage will ....

who makes a good 2 way in this format ?

disabling tweeter in crossover, modifying mid crossover bypassing the low pass portion and repurposing a 1uf cap to reshape the high freq response some. about 5 inches of wire and a little soldering is all that is needed, took me about 20 minutes to do the 1st one

also I had to get nosey and find that class D thread you are in and I purchased a ti eval board to play with , lol I have way more amps than I need around here, tube, a/b, D at least a couple dozen

If its fully functional as new, then no warranty needed, since I will not blow drivers like a 15 year old :-)

it is a different driver than the RF7 II, likely same supplier though..... I can measure distortion using REW

no bravery required, it is a zero cost and fully reversible modification ..... :-)

I did some research and Klipsch use the same horn and driver that they use in the Forte III as the midrange as the mid/tweeter out to 20khz on their cinema surround model KPT-1260H http://assets.klipsch.com/product-specsheets/KPT-1260H-Data-Sheet-v02.pdf The conversion consists of 3 changes to the crossover, no parts required and results in VERY flat response of the mid from 650 out to about 19khz Much better imaging, ZERO fatigue , 100% win win ! If there is interest I will post my changes and measurements.

Here is the mid driver

I ripped apart my NEW khorns last year and changed horns and driver's and crossovers !!

I own multiple eq's and am not using one on this system

had them up, had them down, its not room or other gear since all other speakers are fine.

I have removed the crossover and drawn out the schematic, as suspected there is a lot of attenuation on the mid , but no attenuation on the tweeter in the crossover. Woofer is crossed at 18db/octave, mid is 12db/octave and tweeter is also 18db/octave . Inductor values might not be correct, meter is junk..

Im not giving up on them, I see it as a challenge ! I will fix the crossover to make them flatter and have less of that Klipsch in your face curve :-)

sitting 18 feet away in room about 20x30 feet

No eq on this setup, 1970's pioneer turntable, pioneer reel to reel and then a 845 single ended triode amp. I have MANY speakers from heresy's to cornwalls and Khorns and new onkyo's https://www.onkyousa.com/Products/model.php?m=D-77NE&class=Speaker and ascend sierra 2 http://www.ascendacoustics.com/pages/products/speakers/SRM2/srm2.html and KEF Q100 and KEF Q350 and KEF R900 and VINTAGE pioneer HPM100's and pioneer DSS-7 ( berylium tweeter, boron mid's ) and more.... Only speakers to ever fatigue my ears this way are these Forte III and my Klipsch Horns when new ( I have since completely change the horns and crossover and no more problem ) From experience with much different hardware any hump in the response in the 7k-10k area can make speakers fatiguing ... I just hooked up the sierra 2's next to the forte's and they sound great ! But they dont get very loud with the 15 watts that are available ( only 86db eff. )
