I have 3 Stealth 8s as my mains.
I had one of them repaired under warranty a few years ago.
Now another is making crackling and buzzing noises, basically the same that the other did.
I emailed Emotiva and received this reply:
Hello Bryan,
Unfortunately, Your Stealth 8s is out of warranty so we would not be able to service that product as we do not carry it any longer.
Im sorry for the disappointing news.
I replied back that I'd be happy to pay for repairs, but no reply yet.
If Emotiva won't repair it, does anyone have a recommendation in the Atlanta area?
TIA!

What a shame,I guess they expect us to buy more of there stuff,that will be junk in 5yrs.
Had same issue with my umc-1,,sorry we can't fix it!

Received a reply.
Unfortunately, we no longer have parts for the speakers so we are unable to service them outside of warranty. You could do a trade-in for the monitors. The trade-in value is $170 per monitor.
This is almost heartbreaking. 😭

From your description it would probably be an amp circuit that's getting cranky. The first culprit is usually capacitors, which are easy for any shop to replace. You would always hope to get more than 10 years from electronics parts, but other factors come into play - most notably, heat.
For non-driver related repair a local shop can easily diagnose and repair.

Can you remove the amp and use them as passive??

Can you remove the amp and use them as passive?? I am wondering the same thing. It would depend on how the crossover system works. Each driver has its own amp, so, is there a crossover before both amps? or a filter after each amp? (Probably it's filters after the amps.) These speakers are very well powered! and very well built! Really thick cabinet walls. |

That's a typical response from a lot of companies. Out of warranty service is a hit or miss proposition and especially for products no longer manufactured. I agree with the above suggestions about looking for an electronics repair shop in your area.

A bit of a punt and you have nothing to lose. Check the Electrolytic Capacitors. They could be suspect. If not after you replaced them, relatively cheap to do if you do so on your own. You lose nothing if it doesn't fix it. After that it could be a noisy transistor maybe. Like I said, I am punting, but still trying to help. |

That is correct. I believe they relocated a few years ago. They work on anything it seems including appliances to McIntosh and other higher end stuff. They currently have my JL Audio E-112 sub for repair. Didn’t they used to be on Claremont rd? Try Norman's Electronics in Suwanee. Very reputable and have been around a long time. |

Another brutal response... I hate to say it, but based on this news, I have reservations about ever spending serious money on Emotiva gear. "reservations"...that's merely my frustration and anxiety speaking should my Stealth 8 have a problem in the future. Of course I'll continue to buy Emo stuff. It's just difficult to imagine that a $1700 pair of monitors can go from "perfection" to "permanent paperweight". |

Unfortunately as you can see from my signature, I have been a big fan of Emotiva...but I don’t really picture buying anything further from them either. Now that ToneWinner sells direct via Summit Audio for North America, I can get most of the gear I would have bought from Emotiva if I determined I needed more gear. At this point I will probably keep an eye on Bryston gear, totally reliable and backed by a twenty year warranty that will probably outlive me. Tim |

teaman yep I buy for the long term. Therefore warranty services are important for me. Luckily their amps have been super reliable for me so it’s looking good

As someone that owns Stealth 8's that are out of warranty, I thought I'd offer some possible solutions to either fix or repair dead Stealth 8's. If you have scratchy sounds from your Stealth 8's then, as you know, the amp is on the way out. Unfortunately if one of the amp's fails then there is a risk of getting pure DC rail voltage to one of your speakers. If it's the amp that powers the woofer it might survive but if it's the amp that powers the tweeter, it will most likely melt the tweeter. If you ask Emotiva, they will send you the schematics for the Stealth 8. There is a good chance that one of the output transistors is failing. There is a PNP and NPN output transistor for each of the amps. These are readily available from many sources. If you are proficient with soldering, you can replace these yourself. If you're lucky this will solve your problems. In my case it did not help. If replacing the output transistors does not fix the issue, then things become much more complicated. You could start moving upstream replacing components as you go but without the right test equipment this procedure is hit or miss and certainly not for the faint of heart. After doing a post mortem on my amp, it became clear that the row of power transistors on the underside of the amp were no longer making good mechanical contact with the heat sink on the backside of the Stealth 8. The thermal paste that conducts the heat between the transistors and the heatsink had turned to a white dust and the amp slowly cooked itself over time. Until my amp failed, I was happy with my Stealth 8's. Since I was unwilling to scrap a monitor with one dead amp, my solution was to order a 2 channel 125 watt per channel class D plate amplifier with an integrated DSP. Specifically I used a miniDSP PWR-ICE125 from Parts Express. I had considered going with a 250 watt per channel amp but I discovered that the existing Stealth 8 tweeters are only rated for 80 watts. Replacing the amps and power supply with a plate amplifier is a straightforward procedure. In a nutshell, you remove the back of your Stealth 8. You disconnect the power LED, and the 4 wires that go to the speakers. Then you remove and discard all the amp components including the power supply and the rear heat sink. When you're done you have an empty back plate. Next you cut a really large hole in the back plate of the amp and bolt the plate amplifier in its place. After hooking up the speakers, you're mostly good to go. The only task that remains is to program the DSP. My DSP required a router and windows PC. All the programming is done via a P.C. From a functional point of view, the signal first goes to the DSP. The DSP processes the signal then sends the output to a dedicated amp for the woofer and a dedicated amp for the tweeter. The only downside is that programming the DSP takes some effort if you want your newly fixed monitor to exactly match the characteristics of your un-doctored Stealth 8. I used a reference microphone to ascertain the frequency response of my remaining good Steath 8. Then I was able to program the DSP to set the crossover frequency and set gain to match. And finally, the last option would be to purchase a passive crossover and simply use the dead Stealth 8 with an external amp. If both my Stealth 8's had died, I might have considered this option. I hope this helps someone. Bruce
