Question 1

Is it version 110V or 220V power supply?

Accepted Answer

It has the standard U.S.A. plug.  According to the specification sheet, the internal power supply is compatible with
VOLTAGE:110/120 VAC/60Hz  
So it is NOT compatible with 220v power.

Question 2

The description says it has speaker level inputs but the picture does not show this.  Which is wrong?

Accepted Answer

The picture of the back of the sub is accurate. There are ONLY the two RCA inputs (left and right).

Question 3

How well will this subwoofer work with the yamaha rx-v677 receiver?

Accepted Answer

I have had two KSW-12 subs connected to Sony ES receivers for years.

Haven't had any issues with them.  Just bought a third from New Egg, but haven't cracked the box yet.  I'm finishing a basement and couldn't pass up a recent deal on these... so bought another.

Question 4

This is listed as discontinued by Klipsch. Does the normal warranty still apply?

Accepted Answer

Hello,

Thank you for contacting us in regards to your question.  This item includes a two year limited warranty for parts and labor.

Thank you, 
Newegg Support

Question 5

I noticed the input voltage range is 120 - 230VAC, but the higher voltage is listed as "Export voltage". Does this mean it just works on either, or is it switchable?
I might need to take it from the USA to a country with higher voltage in the future.

Accepted Answer

Unsure, that is a question to be directed to Klipsch directly.  You can contact customer service via their website or their tech support number listed under their contact list.  We unsure always go directly to the technical support source.  
Hope that helps.

Question 6

The product with p/n 1062212 cannot be found on klipsch's website.
I was wondering whether Klipsch would provide any warranty.

Also, this is not the original KSW12 that was discontinued. It seems the product was manufactured for Newegg exclusively. Can anyone confirm?

Accepted Answer

Well I can tell you this much. I had a problem with one (I bought 2) and put a claim in with Klipsch and they sent me a shipping label and RA good for 60 days, but I ended up doing it through Newegg instead as it was quicker. But it seemed like Klipsch was ready to honor the warrantee anyhow.. I can't confirm if this is an exclusive product but I wouldn't doubt it. Seems Klipsch does this for a few other distributors as well.
