@ross6860 i hear ya. That’s why I have not messed with mine. Just visual inspection and sticking my ears to them.
regarding your other question; I have no idea but it would be nice if it worked.
Infinity Kappa 9 S EMIT not functioning or Hearing Loss?
First post after lurking for a couple years, so please be gentle.
I recently acquired a set of Kappa 9s. I know, I know, "amp killers," "poor design," etc. I'm having fun with them for now, so I'm willfully overlooking that part. Currently bi-amped with Audio Research Dual 75 running the top end. A more "budget" 2 channel solid state amp I pillaged from my home theater setup is temporarily running the bottom end with the bass extension of the 9s switched to off.
Question. Is it possible the frequency range of the S EMIT up top is out of my hearing range? I play test tones and the top of my range is somewhere between the 14kHz and 15kHz, but I don't think it's coming from them, rather the EMIT below. This is the case with the S EMIT on BOTH speakers.
I used my 8 year old as a test subject and he said he can definitely hear sound emanating from the top S EMIT, starting around 19kHz. Being the skeptic I am, can I trust that he's hearing from the S EMIT and not the EMIT below?
I thought the S EMITs were crossed over around 10kHz, so I should hear something from them. I'm really far from a technical wizard or electrical expert. Physically digging into and testing crossovers and whatnot is a bit over my head.
There's another forum that has seems to have a more Infinity focused following, but I can't seem to create an account or search the site for whatever reason, so I'm turning to the experts here.

P.S. I've learned SO MUCH from you all, reading most of the top discussions delivered to my inbox every night for the last 2+ years.

fyi- It’s a cheap (almost) free process to measure a speaker’s frequency response to see if something is "broken". RTA apps are free (or cheap) for phone/tablet and you can burn test tones (including pink noise) onto a CD Rom (useful) only if you have a CD player). Play pink noise from your player and place the microphone about 3’ away from each speaker. In the case of tweeters, make sure the mic is placed on axis with the tweeter in that the sounds are pretty directional. This will tell you right away if a chunk of the signal is missing, or attenuated. If you don't have a CD player, and have a spare phone/tablet you can use it as a source. Just use a direct connection to the inputs. There is also a "no desoldering needed" method to see if you have a bad driver vs crossover issues. |
Download a frequency measurement app like Spectroid onto your phone and check the suspect speaker using a classical music selection that has a lot of high frequency. Maybe Rhespighi’s first movement of "The Pines." Test the speakers against each other by switching the balance between them with the signal set to mono. OR Get a copy of the Stereophile Text Disc CD and run the high frequency track switching between the channels. That should tell you whether that EMIT is functioning or not. |
