There's an MFW-15 listed on my local Craigslist for $250.  He claims the amp is still good.  If I go check it out, what should I be looking out for?  I figured I'd ask the owner to power it up without a source and listen for a hum, anything else?  Is there a way to determine from the outside if the amp is a v1, v2 or v3?  And if I can determine the amp version, what can really be said for each?  Are the v2s or v3s really considered reliable?

And how about that price?  It seems like the low $300s is kinda standard for a used MFW-15, but I dunno, $250 still seems like a lot of money for a piece of electronics with such a likelihood of failure in it's future.  Now correct me if that assumption is wrong though!

If I bought it, it would be added to a pair of RS-550s (non-sigs) powered by an Emo UPA-2/USP-1 setup.  I kinda feel like, if I could get a couple years out of it, and then turbo it down the road (in the event of failure in the sub or sudden affluence on my part) then maybe it would make sense.   Thoughts?  Advice?  Concerns?  Criticisms?

Horrible idea. Best bet, give me his email address and I'll email him telling him to kick rocks. And by kick rocks, I mean ship the sub to me. Haha.

Hehe, you're welcome to give him a call!  He seems like a nice enough guy.

I think I'm actually going to pass on it.  If it was a Rosewood cabinet (to match my speakers), then I think I would have bought it with the intention of turbo'ing at some point in the next couple years.  But since it's black, I just can't get myself excited enough about it.

Hi nturchin,

You might want to check with Kevin/Sandbagger.  I believe he has 1 or 2 Rosewood cabinets in his possession.

Thanks for the reply Mark!   I did happen to see him list a pair of turbo'd (turbo-nated?) Rosewoods on the CHT Forums just today.  Man THOSE would be so sweet!

Thanks for passing! I just sent him an email.

Guys, remember this is Craigslist. Prices are negotiable!

If your MFW is going to be hidden and you want a turbo, I have a couple of C stock (aka rough shape) empty cabinets I'd let go cheap. I have packing material. I'm in the W Denver area. Just FYI, you can ship bulk items on Greyhound bus for reasonable prices.

I offered him his asking price and I'll cover shipping which shouldn't be more than $150 so I said I'll give him $400. He said its too much of a hassle. Dammit.

Looking at the ad and the location I bet that's MLS.

What's MLS?

Nay! MLS is farther north and the only thing he has to sell is in his orange jump suit.

MLS is Mark Schiftler. The founder of AVS123. Doing prison time for fraud.

UPDATE:  I'm now the proud owner of a Black MFW-15.  My system went from no sub to lots of sub for the reasonable price of $200.  Honestly, it was seeing Toxis being willing to drop $400 on it that convinced me that my worries and preconceptions about the sub were probably a little over exaggerated.  So I picked it up... No it wasn't from Mark (who is on probation in Boulder County, probably forever).    The seller was a really nice young guy as a matter of fact.

On semi-related note, the fact that AV123 used to be a local operation, DOES mean there's a fair amount of used stuff like MFW-15s, Rockets and X-series out here.   I picked up my Rocket 550s about 2 yrs ago for a cheap price, and I expect I'll upgrade them for 850s at some point, hopefully in the next year.  I know there's better stuff out there, but for the sort of prices you can score old AV123 gear for, I'll probably stick with the stuff for a while.

So I've been trying to research the early days of the MFW-15s and some old posts indicate if the sub has threaded inserts in the base, then it's of an earlier (more reliable?) generation is that true?

Mine have the threaded inserts,
does that mean they're more valuable?^)

Who knows, maybe someday they'll be Legendary or is the term I'm looking for, Epik..
Oops..
no..

those were out of stock at the time,
which is why I bought these MFWs in the first place.

But to answer your question, threaded inserts were used in early models. I don't know if they disappeared in later models, but if they did, it was because these units were heavy enough that moving them around with the brass feet in the threaded inserts could do all kinds of damage to things including the corners of the base of the unit itself where the inserts were located. From what I recall.
