Ok, had a few minutes to spare, ran another test this time using my Frankenstein-MFW with 30hz test tone from BassMekanik V5.0 and the following config. As usual nothing scientific and I wish I had as much time to get into it like Nick did but honestly, all you need to do is perform this simple test, if one has lower output no matter what you do won't help, it needs to be replaced, period.
No AVR, I used my Mac Pro at 50% (In OSX Snow Leopard, Windows 7 would need lower volume setting) volume which outputs to a Radio Shack SSM-1750 mixer. It runs into channel one, all tone controls set to flat and channel 1 gain set to 75%, mixer master volume at 50%. This never changed during this short test.
Plug in V3 amplifier, run gain at 11 o'clock, start 30hz tone on repeat and hold Rat Shack meter 2ft away. The tone changes intensity, max SPL was 90db, lowest was 86db, turn up amplifier gain knob to 100% and max SPL was 94db while lowest was 90db. At no point did the sound come off as intense.
Plug in V1 amplifier (this is the amp that overheats if installed into an MFW), run gain at 11 o'clock, start 30hz tone on repeat and hold rat shack meter 2ft away. Max SPL was 100db, lowest was flickering between 95/96db. Turn up gain to 100% for a split second, was too much for the driver so didn't take a measurement as it was evidently MUCH higher than the driver could handle.
Plug in V2 amplifier, (this is the amp installed in my 1st MFW) run gain at 11 o'clock, start 30hz tone on repeat and hold rat shack meter 2ft away. Max SPL was 101db, lowest was 97db. Turn up gain to 100% for a split second, like the V1 amplifier it was too much for the driver so didn't take a measurement as it was evidently MUCH higher than the driver could handle.
I was able to back off to 10ft away with the V2 amplifier running at 11 o'clock gain and still getting 91db on the meter, which amp would you choose if handed any of these?
The sound intensity was a tad more evident in the V2 than the V1 while any comparison to the V3 that I received to me isn't worth any further testing, it's much weaker than either of my other amplifiers.
I think it's safe to say that Nick got a properly configured V3 amplifier and I received one that definitely has lower output at any volume than my V2 or V1.
Nick mentions that his V3 is very quiet and I agree, it is very quiet and runs cold at all times, very impressive. I do need to mention that my V2 and V1 also run very quiet but in this regard I seem to be lucky considering other comments to the contrary. The V2 and V1 run hot, even when doing nothing so the changes that the US company made regarding transformer and other components have really helped.
The fact we are getting amps without proof of full testing leaves me cold about getting one that works as well as Nicks. Something is not right with some of the V3 amplifiers being sent out, the lack of testing and then publishing the results leaves one to wonder what the real output is with the new amp. I believe Nick when he says his V3 sounds as good or better than the V2. I think the amp he received will last a long time.
Things AV123 could do to improve this amplifier or any amplifier:
1. Get fully qualified external testing PRIOR to releasing ANY amplifier to the public.
2. When you do release a new supposedly improved amplifier when there are forums full of people complaining about amplifier issues TELL US when you release a new one that fixes the issues we were complaining about. Telling us via an email about a new sale that states "Now made in the USA" doesn't tell us there is a new US made amplifier in the box or if it fixes issues people are having with the previous amp.
3. When you take away some of the things in an amplifier like the control module, how about raising the price of the sub 10 bucks to cover the cost of putting in a blank plate so the consumer doesn't get confused when he reaches back there to adjust gain, freq or phase only to hear no changes taking place. Seriously, very unprofessional swap out here, I understand you need to move product but you do want people to return to your site and buy something else right? Put a note in the box that states ignore top control module as it does nothing. I understand you have this note in replacement amplifier boxes being sent out to replace bad V1 and V2 amps, but the guy who really needs it, is the one who just bought the whole MFW and doesn't know anything about it!
4. Prior to putting a new amplifier in ANYTHING or sending one out to a customer make sure it has FCC approval at minimum. Isn't this a law or something? Telling us in a forum it hasn't been fully tested yet is one of the most stupid moves among more than a few stupid moves AV123 has made the past few years. Who doesn't test a product before releasing it, and I don't mean YOU testing it, I mean the agencies who's job it is to insure what you are sending out won't catch fire. Can't afford UL ok, at least get it done by the ones required by law, unless there isn't one, if not let me know.
5. You say they couldn't print anything on the amp until it got approved by the companies after they test it but really, do you need approval to put the AV123 label on it????
Finally, I am VERY disappointed that I am on yet another amplifier, this time a fully redesigned one. This makes it number 6 or 7, honestly, I lost count. I am going to ask AV123 for yet another amp and a label to ship the V3 I received back. If I receive another one that is lower in output than my V2 I'm cutting bait and selling off what I can and cutting my losses. I'll sell the MFW's for whatever I can get for them and move on, I'm sick of going through this.
