no my friend.the speaker ahave awesome bass but it is almost impossible to drive it.
first look at the back to use normal mode and not extended.
what kind of amp are you using?

 

[tinitus]

bass is indeed huge, and at times even scary

have you checked if all woofers are moving ?

i think he means the bass is not tight enough and this is usually lack of driving.
this speaker is a known amp killer.

With these speakers there`s only one way to go; bi-amp the speakers, bypass the original bass-filters and run the basses through some active filters. Everything else is like beating a dead horse, it won`t run anyway. Use the forum to get some cheap & good stuff.

I remember I saw some Infinity crossover schemes having the woofer preceded by a big (1000uF)electrolytic . Is this the case ?

Oh woe ! those things are huge (but slim! ) !!! Yes I did remember well as I found the crossover schematic now :http://www.infinity-classics.de/infinity/technik/manuals/Kappa_9_technical_sheet.pdf
The woofer section has a built in HP consisting of a 2mF electrolytic . I guess if someone is going to bi-amp the thing , to exclude it from the circuit and replicate it at line level.

yes, it is
yet, I have experienced a cheap NAD driving it, with ok result
but one of the few, as he has burned several other amps
he is now driving them with older Nakamichi, and no problems at all
but my 40watt Mirand still sounded better
a bit of a surprise as I didnt even know if it would survive the test
but yeah, it got hot when activating the EQ function
a bit frightening with only one pair output devices
but it worked, and sounded very very nice
he had never heard them play that good before, or after

but I understand there are two Kappa 9 models ?
btw, I think the woofers were replaced, as the surround had rotted away

Have they maybe been repaired ?

It's too bad there is not more interest in this amp.
Is the original designer still around?

propably was the 9.1 or 9.2 or maybe the 9 at normal mode or else your amp

would have fried.
