Problems with Infinity speaker models with Emit tweeters

I did check the Qe and the RSe with the SX-750 and they don't sound good either. Same sort of sound problem they displayed with the AVR 2801. Checked the fuses with the meter. Seem ok. Have not opened the speakers yet, but will do that too eventually. As fas as info goes the Qe seem to have one capacitor only and it is for the tweeter (?). On other hand, many said don't bother changing it, it can't go bad and it's the original... to which for the most part I agree - if the original part is good I never desire to change it.

So what is wrong with them... I desperately need to know. If some pro lives around north Atlanta area/suburbia and is curious to diagnose them, please let me know.

About the Kappa 8... I read that even 200wpc receivers go down the drain with them, which makes you wonder if the Onkyo Integra TX-890 with mere 125wpc would be able to power them without breaking down. I am over my shorts in all this... can't seem to tuck things in so that they work properly and I don't want to sell those out of desperation.
 
Also.. would the TX-890 blow the Qe and/or the RSe if I try/use them with it? What would you recon? I haven't tried it, because the numbers don't seem to give me enough confidence.

Not if you avoid extremely bass heavy music, keep it reasonable with the volume, bass, and loudness and your TX-890 is in good shape.

You read right about the Kappa 8’s, you’ll need a very stout AVR to power them and you’re going to have to be very careful on that volume knob if you use one. When you step up to the 8’s separate’s are the way to go. Amp, preamp..etc. Adcom comes to mind.

I remember my first pair of Kappa 8’s, I bought them on a Saturday and the next day Sunday I cranked them up and I think it was an Denon 3805 AVR I was using…I was just starting my Audio Journey. Anyway I turned the volume up high enough I could hear the music in the backyard…..not even 5 minutes later while I was outback the music started coming in and out…..I walked in the house and the Denon had smoke coming out of it, not a little smoke…..like it was smoking ready to catch fire…..holy cow. I ran to hit the off button LOL !

I was also new to Audiokarma so I immediately got online and started asking questions here. I didn’t know about ohms and all that stuff at the time.

Just food for thought for you, be careful with them and an AVR type receiver. I sure hope you find someone in the area to help you out with the other speakers.

Thanks for sharing! Much appreciated. I will consider going for separates ... I don't want to smoke any gear.. :)

what happens if you play music through a polydome with cracked diaphragm?

The dome is keeping the voice coil stable in the magnet gap. If the dome is no longer stable the voice coil bobbin can canter in the gap, scraping and damaging the wire insulation.

If you can avoid loud and / or bass heavy music you should be okay. But if you like music and sometimes like to crank it up...

AVRs with sufficient cooling for sustained power are rare. Likewise with high current ones. They typically have so many channels that there is severe lack of real estate on the cooling plate. And for the same reason a couple of transistors only for each channel, which can be okay if it's high current mosfets but they are likely BJT's and a single pair is not much headroom for current / power.

Dan13105,

don‘t let this dissuade you from getting Kappa 9’s if the possibility presents itself. They are IMHO Glorious speakers and worthy of at least trying. Everything can be repaired if needed. Had I not lucked out on a pair of Gammas those would be my mains now. The only struggle you’ll have with them is powering them. If you can accept the fact that Pro Amps can do the job (Crown) etc and sound damn good doing it then it’s not such a big deal. Also IMHO the key is a good quality preamp here.

I hope you figure this one out, it's making me possibly reconsider the Infinity Kappa 9s that are at the top of my wish list. I've never personally heard them or any Emit tweeter Infinity, but i have found that some speakers sounded good to me, but would cause pain after a listening session. Hopefully Kappa 9s won't be one of them. Have you tried toeing them out, instead of pointed directly at you? Are you using the same source every time you tried different receivers or speakers, like a cd player for instance?

I agree with 7.62 had my 9s for 8 years, they sound great and I have listened to them for 6-7 hours at a time. I found a good combo in parasound pre amp and carver amps in bi amp mode. IMG_0007.jpeg
 
You should see where my Gammas are parked..LOL ! Bahamayellow and I might be in competition for the smallest listening space ;). I don’t even care because they still sound GLORIOUS as near field monitors. Now if I could only find Beta‘s for $150 ! Yeah Baby !

Yo!
Play this on your delta/gammas, lemme know what you think.

sounds effin' sublime on the maggies! I keep forgetting what an absolute savant Prince was on any instrument he cared to play. Waay underrated guitarist.

Way.

It wasn't critique. It just looks funny.
I know they sound great up close as well. But at one point you might need a higher chair to reach the correct height.. ;)

and this, hermano

Probably best in the morning when the wife is at work.
 
I was just making fun of us Retro Pete and Hi Bahamayellow…waving. Oh….Jazzman will Do and definitely while the better 1/2 is at work. Lately I’ve been jamming the Yamaha‘s from 76-77 with a 40 watt KR-4400 Vintage Receiver. Unbelievable how great it sounds, just takes ya back to live performing !

And Agreed on the late Prince, Stud Muffin ! And Les, dudes a genius in my book.
 
Soo, to conclude - the cuprit was ... the amplification. No problems with the hearing, just too many all-of-a-sudden-Infinities (it's the official medical diagnose).
Apparently all of them demand juice. Some more (the ones with the EMITs) and some a bit (probably 3-4%) less - the ones with the Polydome tweeters.
All of them, however bring their best at about or above 150wpc high current amplification with separates.

Maybe too with those integrated amps from recent years, but I can't tell about them yet. Anything less and they become fatiguing after a while, especially if you have two day mini festivals at home, as you do.

Which begs to tell.. - as I currently have at home, five pairs with EMITs and three pairs with polydome tweeters - the polydomes are absolutely fantastic tweeters too. A bit less.. presence, sure, but sound more natural when powered with the same source as the EMIT ones especially towards the end of the 2-3 day home festival's after party.
Cheers and many thanks to you all who tried to help!

But.. You showed defective polydome mids. They need repair or replacing to sound as they should. ;)

Yes, you are right - I mistakenly wrote "polydome tweeters" while clearly meaning polycell tweeters!
And by the way, I haven't touched the Kappas yet since I have not done the repair so everyone can sleep well. :)
 
I was hoping there's something that can solve this issue, as my newly acquired Kappa 8.1 has one Emmit-R sounds a bit harsh when crank up. My amp is Bystron 4B so I don't think it was an issue with under power as a matter of fact I bi-amp and still has the same problem. Anyone can chime in and help. I been following this thread hoping to find the remedy.
