Well gents, I got a replacement amp and I'm not really sure what to think. They weigh about half of what the others did and now don't support the seperate phase/gain/xover panel. Check it out...if some one can post them, I have no idea how...

Looks great to me, the knobs bear an eerie resemblance to the knobs on the amps Emotiva is using for their subs.

If these new batch of amps turn out to be solid, I will definitely consider trying a MFDub.

Put it in and tell us your impressions! What are you waiting for

Edit: It would not surprise me if they used the same manufacturer, considering how they worked together in the past.

well I hooked it up. Not good. I had to have it at 9/10 to match my others in output at around 4/10. But it's still not the same so say a prayer for your v2 amps guys.

I don't know what to think here except less is more? I hope? Can someone like Mark Seaton or Craigsub look at this and chime in?

Wait, you had an amp failure or what?

This is what they are replacing the old amps with?

Looks like the transformer is shielded with some foil, and the boards are definitly different. I am very curious now....

I hope someone with component level knowlege can chime in on the amp design....

Ouch!

And whats with the cheap inputs? They really used a yellow for LFE? My first thought was "What the hell is a video jack doing on a sub amp?". At least use purple of white.....

No auto setting?

I respectfully disagree (not on the cheap part). The MFW was originally a $900 sub, If I had paid that much, I would not expect a cheap replacement amp such as the OP received.

They might as well just get BASH to custom them some amps, and be done with this cheap bull **** they keep trying to push on their customers.

Whats the deal with removing options on the amp? I would be beyond pissed if I had an amp go, and I got an inferior amp to replace it. What about the people that were using the Line level inputs?

Doesnt matter what it "retailed" for, its a cheaply built sub using a rather cheap driver and plate amp. It will give you output, but what 15" ported sub won't?

Thanks for stating the obvious. I expect the same level of design that went into the original which was not the cheap subwoofer it seems to be now. Nobody is expecting the same as is installed in a 5k sub but this is a HUGE step down from the previous design.

This renders the controller moot, no more auto on/off, cheap inputs and boards that look like you better be gentle pushing in the rca cables.

We don't even know if it meets the previous amplifiers spec power wise or eq wise for this driver and enclosure. AV123 has been silent, not even MLS under TADG or whatever his new name is today has posted anything.

So, is this a bad joke or is this really the new amplifier? If this is the new amp then those of us who receive them will never be able to get a decent price for it the MFW if we sell it.

I can see it now, ignore that nice looking controller and oh, that cheesy looking thing where the amp is, no worries it's the new design, trust me it's as good as it was before, you just don't have the same options for hook ups as I did when I bought it.

Just....Damn....

Tell you what, go piss on another thread ok, we get it, everything you haven't built is cheap with cheap amps. You can kill anything Seaton makes and now you're here to school us on how dreary the MFW is.

What this thread is for, is to get an opinion from someone who knows this sub AND might know about the amplifier. If you don't, then thanks for your commentary about the junk we bought, move on please.

Someone who gets it! +10000 agreed! Some of us who bought this and are still waiting for a good amp might get this one and no matter what we should get at minimum what we paid for, not less and this one is clearly less.

If this is NOT what they are sending then I'll openly apologize to AV123, if this is what shows up at my door there will be hell to pay.

Have you installed it yet, do you have a pic of the box? Was there the usual letter explaining anything like hey the controller is no longer needed?

Updates please.

THe OP asked about the quality of the plate amp. SO he got an honest answer. Its cheaply built using cheap parts. So sorry AV123 used cheap parts in this product.

Whats cheap? Can you be more specific for those of us learning?
  • Transformer
  • Capacitors
  • Colors of inputs(Who cares).
Its obviously less "mass" but electronic equipment is more than a sum of its parts....

My 4 year old nephew can tell it's a cheap amplifier, this is a replacement product so you obviously don't know how it stacks up to the original however I'm nearly 100% certain you would say the same thing about that. So, no help what so ever.

EDIT: ntrain6943, I'm not going to delete what I said because I said it. But I'll apologize for getting upset, I have nearly 2 years invested in this investment and seeing this amplifier as the replacement tripped my trigger. I apologize for taking it out on you.

I'm not making this up, this is the amp. Read step 9 carefully...

http://img171.imageshack.us/gal.php?g=img1459q.jpg

I already took apart one of the last batch amps (popped) and am using the replaced module board in an OLD amp for the one this was supposed to replace. I played with the one I posted for about an hour and gave up. I asked Kyle about it and he said it was the same spec and output would be the same but then again, he's not gonna tell me it cost $3 wholesale and might get me through the summer.

The amplifier module board looks similar to the previous one, as to the circuits it's hard to say. I know I'll know better when I get mine this week or next. The circuits of the amplifier was pretty nice in the last series of bad amps that I received so it must be something in the design that's flawed or the quality of the parts that someone is nicely installing.

You're right, the amount of parts doesn't mean it's bad but the lack of options sure is a tell for me. If this is the new amp, they might as well send us a block off plate for the controller as well.

crOwcaine,

Thanks! looks like this is the amp I can look forward to receiving late this week or early next week. I'll be able to compare side by side and I'll take close up pics of each amp side by side as well.

Thanks again.

same hum as always. Cheater helps but it's still there if your ear is a foot or so away from it. How is the transformer an upgrade?

You got me beat, here is my break down.

MFW # 1, replaced original amplifier due to running hot, original amplifier is running my frankenstein MFW in the basement and runs mostly cool down there since it's no longer in a box. Received the replacment last July. The amplifier was an obvious upgrade as it had more midbass slam and just sounded better and it has been running perfectly since.

MFW # 2, 2 drivers and now 6 amplifiers, it's jinxed or something as I can't get past a few weeks before it blows up.

Here is whats funny, I have run these things to the tune of 125db at the listening position for hours and they don't break a sweat. They always blow up when powered on, how frigged is that?

So, what i'm getting from your initial assesment is that this amplifier is a down grade not just in options but power as well?
