Pioneer CS99 - midrange?

Have an old pair of Pioneer CS99s and I SO want to love them, as they easily fill my medium/large room with sound, but the mid range is so muffled & "flabby" for lack of a better word. I can feel the bass even if it's not very controlled or detailed. Highs are powerful. It's just not balanced sounding and, again, muffled.

Drivers all look "fine" visually. Sound seems to be coming out of all of them (5 each). Have no idea if crossover or caps are sick, or not. How much impact would either have?

Having fun with them at higher volume and listening far field. Any chance of taming the muffled mids(?) for near field use?

You might get some midrange and high frequency improvement with a recap, but don't expect miracles!
 
Recaps don’t really help .
I have a pair of those. And the 99a s.
Use a equalizer. Cut the midrange . Issue solved.

I’ve got news for the 99a haters. I just had one of the drivers repaired due to a rubbing voice coil. By MillerSound. Close to me. Read up . Bill told me the driver in the 99a is an excellent one, probably would cost 8/900 to make one today.
 
Always found the midrange irritating even after recapping and disconnecting 1 mid-range driver.
Even put an L-pad potentiometer on the remaing mid-range to try and tame it.
Still irritating, to my ears anyway.
One of those speakers that I really wanted to like but just couldn't.

You can like it . Put an eq in, cut the 500 and you’re done. I’ve had plenty of experience with the cs series.
 
The quality of the drivers is immaterial if the system concept is sonic crap.
The first properly working loudspeaker I heard, flaws and all, was the Dahlquist DQ-10. They got it mostly right, and refined it to three drivers as a 3-way with the DQ-20.
Before that, it seemed to be very hit-and-miss with no baseline beyond simple frequency response plots that ignored driver phasing, ringing, diffraction, ect.

The latter 1970s saw a general overall improvement of what domestic loudspeaker systems were to do and how to accomplish it.
