Basement Home Theater - Broken SVS Sub & How I Diagnosed and Fixed It

- One of my SVS PB-1000 PRO subwoofers quit working the other day. This is how I diagnosed and worked with SVS Tech support to get it fixed after removing the plate amp and performing a driver bump test. Links to the products used for this build are below.

Awesome video! I'm having an issue with a PB13 Ultra. I'm going to use your methods for trouble shooting. Thanks for posting this!!
Thanks - hopefully it helps! Good luck
Svs supplemental: To test if your 9-volt battery is good, place both battery terminals on your tongue. If you feel pain in your tongue, then your battery is good.
😂😂 Exactly! I should've thought of that!
Such a cool video. Excellent work by you. Thanks for sharing. Very helpful video.
Thank you very much! I hope it does help someone along the way if they run into the same issue.
Thanks, very helpful video.
Thank you! Glad it helps
I replaced my PB-4000's amp and SVS customer service was excellent.
Glad to hear it!
plate amps have the lifespan of a firefly usually. I replaced the plate amp on a Bowers sub by using a spare receiver channel. later I bought an old Velodyne and used the plate amp from it. The reason I bought my current subs is they use Ice modules for plate amps, a pretty reliable class D amp. And they have 12 volt triggers.
That's some creative thinking to keep a subwoofer in service! Nice work 👍
@@TyEichele A lot of experience, the one good thing about growing old, not to mention three years of electronics training. Until companies start putting amps with real current in subs (and some do) nothing will change
most of these svs plate amps have the same issue no sound even those aprts express plate amps as well. Im wondering what could be the issue
@@Nelan555 I never pay much attention to a brand. Doesn't matter much. As long as the industry insists on saving a few bucks on disposable amps it's going to be a problem.
A cheap amp meant for left/right could power a couple of subs fine.
To be honest, what I liked most was looking into the enclosure. Also, good to see that SVS's customer service is as good as everyone says. How long was your sub out of commission?
I noticed it on a Wednesday and received the amp the following Monday, so not even a week! Thanks 👍
My sb1000 was out of warranty by quite a bit. The lfe terminal got broken on the plate amp, wasn’t SVS fault at all. I called and asked about buying a new amp and they sent me a new amp for free. Some of the best customer service I’ve ever had!
Wow that is awesome customer service!
Hi, just a couple of days ago I did a similar operation)) they also sent me a new amplifier, installed it and it all worked. I have a request for you, share your avr settings, in terms of bass, the main speakers are set to small? what volume level is set in svs?
Interesting indeed. My Denon has all the speakers set to small yes. My LFE is at 120 Hz. The Subwoofer output in the Denon is between -6 to -8 depending on the movie or how much bass I want. The SVS app has both the subs set at -10 for Volume level. The MiniDSP also has a setting which is currently at +6 for all channels. Does that answer your questions?
Wow, two subs blown in one thread. Not the first time I’ve heard about plate amp failures in researching Rel and SVS to replace/augment MartinLogan Depthi subs which are too light on power for HT. Good to see a quick response from SVS, but it is bothersome to see so repeated occasions of failures.
@@bigdogaxis Agreed - hopefully just a fluke deal, guess time will tell. I'll have to update with another video if it happens again!
@@TyEichele Thanks for the reply Ty. I realize it’s a trade-off quality/cost for these manufacturers, that is why the customer service is paramount. Furthermore, if they can identify the failing component(s) then the issue goes away. Thanks again for the video.
hmm.
I was hoping to figure out why my CT-150 Velodyne (yeah it's pretty old but hasn't been used in years in my warm living room as a table for my receiver. lol)
I turned it off permanently because occasionally I'll get a loud boom even when not in use. When I get close to the woofer there's an occasional static. I've replaced the cable. Still an issue.
Is my expensive seldom used subwoofer just a table now?
I'm not sure to be honest....My guess would be something in the plate amp itself causing the issue? But that's just a guess....Unless there is power issues like a grounding issue or something, I'm out of ideas as well. Good luck though - just have to keep trying different things or might be time to say goodbye to it. 😟
@@TyEichele yeah. I mean it's only been over 25 years. time to go shopping. lol.
Blown plate amps are becoming the norm with SVS Subwoofers. I'm starting to regret buying their subs. It's an inconvenience when your subs are down and out.
Oh for sure - as with any equipment! I haven't really seen a whole lot on common plate amp issues with SVS. I'm glad their warranty is top-notch though. That always helps when you are faced with a situation like this.
@@TyEichele you don't know what you are saying. Svs and parts express get their plate amps from the same company these amps don't last 95% of them go bad in 6 months. I have had amps that don't last one week. Its always the same issue, coming on but no sound. Its something on the circuit board of the amp that is going bad very fast. If it doesn''t come on its because the high voltage caps are bad causing the transistors to get fried but most of the issues like i said no sound after a little while of use. They themselves make it very difficult for you to repair because they are changing the part numbers on the parts on the circuit board they give you no schematics for it
How long did you have the SVS for this to happen?
That's a good question - I've had them for pretty close to a year but I bought them several months before my theater was finished so they just sat for the first few months. I've had them in use for maybe 3-4, maybe 5 months I'm guessing. And not very often at that either.
@@TyEichele that’s wired that your amps have stopped working. I have two 12 inch Polk audio subs which are going on 3 years now and never had to replace a amplifier ones which for a brand like SVS is kinda shocking to hear that the amps stopped working
@@Lowkey_nxthxn Agreed. Here's to hoping it doesn't happen again! 🤞
@@TyEichele I hope so to but keep us updated for future videos
I just bought one of these and a friend immediately bashed my purchase decision saying SVS are 'poor quality mass market products that dont last'. Having used two of these, what's your opinion on quality of svs subs?
I don't think that way about them at all. In fact, they are pretty popular from what I can see when I was researching them. I am completely happy with mine, and they are the entry level models being the PB-1000 Pro....you can clearly go up in size and quality when you get to their advanced models, I just didn't have the money for them.
@TyEichele Thanks for the feedback, so the second one is still fine and the one with new plate works well to date?
@@lenanaH Correct!
@@TyEichele Fantastic, cheers 🍻
I have the same sub, might just run it passive if the amp blows, tthe class d amp sux
Do you think it would do much as a passive sub? I was thinking if it happens to me when they are out of warranty that I might power them with an external amp like a Crown or other rack-mounted solution. Would take some minor modification to the enclosure but maybe just a SpeakOn connection or something. It sucks to have to invest even more money that way but I bet it might even be cheaper than a replacement OEM plate amp? Fingers crossed it doesn't happen in the first place 🤞
@@TyEichele worth a try
@@TyEichele
Why is the mini DSP needed in your setup?
@@daveslk It allows you to set up a custom EQ specific to your room and dial in your entire subwoofer system, so they work together and not against each other. If you have multiple subwoofers it really is a must-have to get them to work effectively. Skim through my video here for more details on how it works and look at the end result!

@@TyEichele I will check it out. Thank you.
It looks like the old plate amp has blown capacitors. That's all that white gunk you see that's all over the board.
I'm not sure if that is true because if you look closely, the new plate amp has the same white stuff in multiple areas as well. I could be wrong, but I'm guessing it's some sort of sealant?
The white stuff is just glue. All subwoofer amps have glue of some description over any component that could vibrate at the low frequencies. Vibration can not only create rattling noise but cause PCB fractures in the solder or copper tracks.
Sorry, but SVS just doesn't make subs with the same reliability as they used to be in the early 2000s. WAY too many failures of this "high tech" BS. It is a subwoofer. I'd much rather it just work.
