Or, better yet, use a crossover designed 25 years later with better tools.That's true, however, I afraid not many kappa 9 owner want to abandon the original crossover altogether especially the adjustability.
Infinity Kappa 9, manual request.
I'm looking for the original manual for my newly purchased Kappa 9. I have the technical bulletin but was hoping a manual exists somewhere. Just the PDF would be great.
I purchase these and they're like new looking, everything was great but apparently they don't sound good. Turns out that when the refurbed them they miss wired the woofers and they were wired backwards in series so they just cancelled each other out.
They're connected to a set of large tube amps, sound great.

They were notorious amp destroyers due to 1 ohm impedance that was not needed.http://www.infinity-classics.de/technik/manuals/Kappa_9_technical_sheet.pdf The low frequency crossover is the offender (L12 15mH), use a good subwoofer amp drive the woofers directly (bypass the speaker internal low frequency crossover) can solve that problem. https://www.parts-express.com/dayton-audio-sa1000-subwoofer-amplifier-rack-mountable--300-811?gclid=... |
