Got My Replacement Amp from AV123.... - Page 3

post #61 of 230
Tell us a little more about this goo.

Is it rigid like solidified silicone or slime like? I would think that if you're calling it goo, its probably the later, but I was just wanting to be sure.

Strange thing about the hum, on my MFW that has gone through amps I had two where I had no hum at all and didn't need a cheater plug and two where I had a ground loop hum that the cheater plug mostly eliminated. On the MFW that has not had any issues I do not need a cheater plug.

I don't think this means any more than the fact that some electronics are more sensitive to hum than others. The only other piece I had to use a cheater plug on was my old BFD. Weird really.

well, it might certainly indicate an inconsistency with production of these amps. that would not suprise me.

on a side note...still no letter/email about the mfw15 amps, but...they DID have time to send me yet another sale email on the rs850's...so i guess they got the "important" stuff outta the way today at least. LOL

I doubt the same people working on the solution to the amp problem are sending out bulk mail of an ad which has appeared on the website for days now.

Maybe I'm wrong though.

edit: as I'm waiting for an amp, I'm looking forward to a solution as much as anyone.
post #65 of 230
ya know..i was just reading over at their site..and i wondered if we will all be seeing something like this for the mfw15 SOON...

Now, anticipating the only outcry that I can anticipate (well, not the only one – but the one “potential one”) I will say this… IF you own a UFW-12 and want to get a replacement amp as outlined in “choice number one” and you do not feel that asking you for the $79 dollars plus freight is acceptable – I will send you an amp at No Cost… I will however want your amp back and again, I will ask for a Liability Release… Personally, the modified amp is worth well over 3X this amount – but I will not argue with the fact that some of you expected more… based on our company history and mine personally. You have every right to as well.


BTW...anyone notice any BIG differences in the HotRod upgraded driver vs the stock MFW15 driver??? other than the size of the driver of course?


now this is the kind of driver i expected in the MFW15....honestly

Pure-Evil, your countless digs are what I have warned about.
You just can't seem to post anything without taking jabs.

You have been banned from this thread until you learn to post your thoughts without being inflammatory and repetitive. Enough already! We get your point.

1-Provide male end connectors for black/red wires and shorten them-making these wires plug and play.
2-Provide a 6 inch control wire preinstalled with a female end for direct connection to existing sub control wire-again making installation hassle free and plug and play.
3-Provide Instruction sheet-just a simple word document would do, or get ready for customer service calls!!


This is based on my amp and experience with it and I hope he takes my suggestions and applies them to the replacement amps. It would just be one more way IMO, to make this easier on the customer.

Strange. All my replacement amps have come with connectors that matched the amps they were replacing. The swaps were all pretty easy.

That has been on their site ever since they've been taking pre-orders for the HR...
And, btw, what is it about the driver that you don't like? You're the only one I've ever seen harping about the MFW-15 drivers?!? Oh, never mind...

I will say the HR driver is nice to look at and if they come up with an HR upgrade (amp and driver?) for the MFW I'd consider it. It would be great to be able to increase the performance of this thing to even more impressive levels.

Bought my MFW15 (with MTMs and CS center) on the Black Friday Sale. Sat in my garage for two months before I unpacked it. I've been using it for the past 2 months now without issue. Amp is warm all the time. Slight hum, but fixed with a cheater plug.

As for the goo...like I said it is some sort of insulator and I believe probably wont be on the newly revised amps.

There is only three of these amps in existence for now. I have one, and 2 part time engineers have the others. I dont know why I got one and someone else didn't. I do know that as a case in point and as history notes, I have been known to be very forceful and sure when expressing my displeasure and getting results-That benefit me.


lol

Anyway, sub sounds great and I only hope that everyone gets taken care of and satisfied with a quality replacement. Like I said, I have only had this sub for less that 5 days and I do know MLS had my amp on a bench "Burning it in" as he said for 2 days straight, whatever that means.

*Also, Thanks to keyser for taking that guy off the thread. I understand he is upset but at this point their is nothing we can do about what happened-just a solution that works.

Burn in just means it was run for a period of time and if done right it was run at higher levels for peak periods to see if it fails. If it passes this set period then it's deemed worthy to send to the consumer.

I don't know about the speaker industry but back in the day when I supervised computers built on an assembly line we had to burn computers in for 4 hours using scripts that stressed different components over that period.

You would laugh at how many worked perfectly at the final assembly point but had "issues" at the burn in rack. This is why burn in is so important, you find the weak ones there so the buyer only gets the good product.

Let's just hope this isn't a custom, one-off, hand-worked job... It certainly doesn't sound like what you got is the final solution, considering the lack of connectors.

Yeah, there's nothing visually appealing about the driver, but who cares what it looks like? I tend to leave the grill on and listen to mine.

I was thinking more along the lines of them improving the driver later, I don't buy drivers based on looks either. I think the user facing side of the MFW looks fine as is.
post #76 of 230
I was really under the impression the new amps were coming in fixed and they would be used in the new subs and sent to existing customers with bad amps.

Was I dreaming?

Yes, this is what MLS said he did on his bench. He did mention that it went over what it was supposed to do so maybe thats what he meant.

The looks of the user facing side of the existing driver is important for me, as it takes about 5 minutes until the grill cover blows off of mine and ends up on the floor anyway.

LOL! Haven't done that yet. But, there have been times when the output pressurized my room so much that I thought the grill cover should have blown off.

Frankly, I just keep the grill cover off anyway. Every once in awhile I'll take a look at the sub while playing "vigorous" material just to be able to see the excursion of the driver.

Yes a Hot Rod MFW-15 upgrade driver would be sweet, though the stock driver is obviously pretty efficient and it extends pretty low though the box is a good size .

Now that ive thought about it, I am not sure how much better a driver you could find for the MFW box and 350 watts.

After all subwoofer guru Mark Seaton designed the MFW, I am pretty sure he chose or designed the driver that is in it.

I hope AV123 found a solution to the MFW-15s amp problem because I still want another one when they get it straightened out. Meanwhile , my
working MFW-15 is still kicking away , no problem. This is not for sure but I am pretty sure since I got it last September that I have put somewhere around 600 hours on it.
post #82 of 230
James,

It sounds like you might be in the clear. One thing that bothers me is that MLS has said that even with quality parts in the original amp design, that there is a weakness in some output component that might be a problem later one. That would still have me wanting one of the new amps from the US company that's suppose to have that part redesigned as well.

?? so why not switch out whatever output component it is with a quality part as well? If your gonna fix the amp , fix the whole thing.

Agreed, driver only wouldn't make much sense, I'm more interested in a full HR, both driver and amplifier unless the driver could handle a higher output amp that is. If the design can't be improved on with a combo, I'm good with that, I love it as it (sans amp issue of course).

*sigh* That is not the Hotrod driver that anyone will be getting. That is a picture of the stock driver / originally planned Hotrod driver. That original Hotrod driver was going to simply be a reworked version of the original UFW-12 driver. That's what's in the picture you posted. However, the original driver maker closed up shop in the US and moved their operation to Asia, and apparently that meant a new driver had to be found. As I understand it the new hotrod driver will be made by Acoustic Elegance and will basically look like this:



However what you don't seem to understand is that the appearance of the driver have nothing to do with the performance. You can have a stamped basket driver that works great, and you can have a cast basket driver that doesn't. You can't judge a driver's performance by its "bling".

Even if a driver/amp upgrade was available I would not buy it. It aint gonna happen , the MFW is a VERY good performer.

Correctamundo!



BTW I asked Craigsub what is the most expensive subwoofer that he has heard that the MFW-15 beats in performance, he said THIS ONE.
BTW that is actually a good price because that subwoofer lists for $5000.
post #87 of 230
Ahh heck , just buy one of these bad boys , stick it in and your MFW will ,,ummm suck.


lol!
post #88 of 230
Countless business decisions had to be made when the MFW was conceived. Obtaining high performance without ending up with an MFW that would cost an extra $100, just to have a driver that is cast instead of stamped and has a heftier looking overall appearance helps to explain why the MFW is one of the best performers for the money.

Given the fact that the first batch of MFWs had a failure rate of 4% (not 30% like the second batch), strongly suggests that tolerances in certain parts went to hell. Information has not flowed the way it should have. I seem to remember that 2.5% failure rate was considered "normal".

I don't need to rehash many issues in this ongoing saga. There are things that should have been done differently. The most disappointing thing is that people were sent 3 or 4 replacment amps. When the second batch started failing, the two Marks (and others) should have known that they had a bad batch of amps and stopped sending out one bad amp after another. Figuring out exactly what was going wrong with the second batch should have started immediately and no more MFWs should have shipped.

Talk of cash flow is no excuse.

Every subwoofer manufacturer has to determine the cost-to-benefit ratio. IMHO ,most ID subs have a better cost-to-benefit ratio than B & M products.
I can't help thinking of the J L Audio F series. Absolutely beautiful both inside and out. But, how much did this add to the cost? J L products are slotted for a different group of buyers. These are the people who may someday consider the BMF. The original presentations of the BMF showed a no-holds-barred design. If they go ahead with the BMF we will see how the implementation holds up under close scrutiny.

Hmmm, well I would think the real wood veneer on the MFWs is just as expensive as the finish on the JLs , if not more.

Info in the BMF is HERE, for those wondering.

AV123 is charging $100 for wood veneer, (which seems to have had a disproportionate number of problems). Certain finishes had to be dropped completely as the reality of trying to bring them to market became apparent. An example is Diamond Rosa Palisander, that took something like 6 months to figure out that it was not stable enough to use.

Most ID companies add $200 for piano black, J L charges $100. I would consider that very reasonable.

A representative of J L told me that they are looking at real wood veneers as an option somtime later on. Meanwhile, piano black is their top finish, (as it is with many other companies).
