One of my EP800s went dead today. I pulled the fuse box and saw a blown fuse. After I replaced it, it immediately blew again. I also tried swapping out the fuse box from my other EP800, and it blew immediately in the damaged speaker.

I called Axiom and JC answered. When I told him what happened he said that the EP800 amps are going through another redesign because there has been a significant amount of this happening. He's going to send me an RMA number, but it will be about 3 weeks until the amp is redesigned and a replacement is sent. For now, only one will come. Another later on (I guess the damaged ones will take priority).

Although I applaud Axiom's unbeatable customer service, I am kind of dissapointed. This will be the 3rd time I have to replace the amps. I know I bought the subs before they were actually released (via the owner's club), but I was hoping the last amp change out would have fixed the problem. It is time consuming to replace amps.

Anyway... Enough of my whining. I'll just have to make due on one EP800 for a couple of weeks. Things could be worse! \:\)

Just wnated all EP800 owners to know.

Thanks for the heads-up. It certainly is disappointing. It's hard to get things that just work anymore. I'm going to go make sure both of my EP800s are actually working. \:\)

Bummer Steve, but good to hear from you. \:\)

Mine has managed to stay strong thus far... I'll now have to keep my fingers crossed.

That sucks. It would not happen with a bigger company, but then you would pay 3x the price and never get anybody to answer the phone. Hopefully this is the last mod needed to perfect the 800.

Hey guys, time for an update.

I just got my new amp for the blown EP800 yesterday! The new amp appears to be significantly different than the old. Although the plate indicates a 150W draw, I think they are just using plates that they had in stock. The black protection boot was not attached to the plate, so I was able to take a quick peek inside, and there are 2 toroids there so I am assuming this may be a dual amp (I'm not sure about the old amp since the boot was attached). Another reason I believe the new amp to be a dual amp is that it contains 8 binding posts (4 pairs) instead of 4 (2 pairs). With the old setup, the top driver was jumpered off of the bottom, you had to double lug the wires. Each driver has 2 pairs of binding posts.

Because of the significant difference, the changeout required the removal of both drivers and all internal wiring. The new amp came with pre-attached wires on the lugs (4 pairs). The entire replacement took me about 90 minutes.

Initial impressions are:

1) There is definitely more driver throw. I only have to have the gain at about 50% to get the same throw I get on my other EP800 when it is at 90%.
2) Bass appears to be "tighter" or "punchier". I tried playing several songs last night that have quick bass, and there really appears to be a difference bewteen both of my EP800s. I even called my wife in and did a blind A-B test, and she was able to tell all three times which was the new versus the old amp.

The new amp did not come with any techinical data, so I E-mailed Brent to ask for specs on the new amp. Alan, if you have any details I'd be really interested to know (it's the EE in me).

Anyway, so far so good! My initial impressions are that I much prefer the sound of the new amp to the old, and hopefully this one keeps chugging! I'm also hoping I can get the replacement amp for my second EP800 soon!

Happy Holidays all!
