Did anyone ever tell you what MFW stands for? Well, I won't post it here, but you can guess.

I bought mine in 2008/9 ish, had trouble with it ever since. Got the run around right before they went out of business. Had problems with the driver in the cabinet mounted in a hole too large, causing screws that were stripped out of the particle board, causing air leaks, amp went bad, bought another amp, now this amp appears to be going bad.

When It worked, I was happy with it, but barely. My room is not very big, but the adjoining rooms can't be closed off, so I have lots of connected air space.

I am quite sure 2 x MFW-15 would have been plenty. When my MFW was working properly, I thought about getting another woofer, but never did, because I can't buy another mfw ( out of business), and I just have a little OCD problem with things that are "unmatched". :-)

So now I don't have that problem. I have a woofer that I want to set on fire, dance around while chanting, then piss on it to put it out before the cops come from my neighbors complaining about me burning stuff in city limits. I think I'd rather pay someone to beat on a drum at appropriate times in the movie than put up with one more ounce of trouble from this **w-15. But I digress.

I am broke, but that never stopped me before. LOL. So, if you were to buy two new powered woofers on a "budget", realizing there is no such thing as a good cheap subwoofer, what would it be. Two 12s? Two 15's? what brand? Would you mix / match sizes of same brand?

This time around, my emphasis would be on !@#$% reliability!

Good news, there are a couple of "budget minded" subwoofers to be had. Either a Klipsch, RW-12d or a BIC, PL-200. Both are 12" and both are tested and spec'd to be pretty good stuff for "budget minded" subwoofers.

Sounds like a good use of a defective subwoofer but it's the air resource board that will getcha. tongue.gif

FYI, it's not a good idea to mix and match due to inherent incompatibility issues. As to reliability, that issue is always "luck" dependent.

wow... checked the prices, two of either of those is less than I've paid for my !@$%MFW-15 if you add the additional purchased amp for the failed first amp in my mfw ( I had to buy it after they went out of business )

I like your party theme. cool.gif

A pair of Klipsch, RW-12d's, delivered, when on sale at Newegg can be had for $600.00. A very well received 12" subwoofer.

I would do the MFW-15 Turbo upgrade. Would probably equal about four of those Klipsch subs.

Im not sure my cabinet can handle it, due to the hole that was cut oversized. Not sure if the new driver screw placement would fall in the same holes or further back which would be ideal. I guess I could "manufacture" some sort of adapter ring, but at this point, I am tired of throwing good money after bad, and ready to wash my hands of the entire mfw-15 debacle. I feel like I've walked around for 4 years with dog crap on my shoe.

Can the OP give a little more guidance on what they mean by "budget" and what size room they have?

If they are looking at two subs at around the list price of an MFW circa '08, then PSA's XV15, or for less money SVS's PB1000's would be a thought. The PSA will win the output game (by a lot), and Tom V. is the "V" from SVS, (but the company itself is still rather new) a pair, shipped, comes in around $1,600. The SVS PB1000's come from a company with a rock solid reputation, and costs ~$1,000 shipped for a pair. Both subs have a rather comprehensive 5 year warranty program, and are backed up with solid customer service. Neither are as pretty as a wood veneer MFW (as long as that veneer isn't cracking/splitting, etc).

Larger, more capable, and more costly, subs exist from both companies.


***Side note, as a former MFW owner, who at least lived within driving distance of AV123 when they still existed, I remember the frustration that the subs caused, including several 150 mile round trip drives to drop off/swap/pick up replacements. That memory is one that spurred me on to brands I felt did a better job with backing up their products. In my case it was going back to SVS for subs. While other companies products may have more bang for the buck, and may very well be great companies, I have developed a bit of a risk adverse nature. Hence, solid warranties and customer service, mixed with good reports of reliability have kind of swamped raw spl/$ for me. These concerns do affect my recommendations, so take them with a grain of salt as other peoples desires and motivations may not match my own. Many other companies exist that may/do have solid products, such as Hsu, Rythmik, Seaton in the sub world, and the OP would be well served looking into those brands as well.

Yes. I would be willing to go up to about $1000 total(tax/delivery,etc), which is more than I paid for the mfw obviously, but this time around I'm willing to spend a few more bucks. Customer service does rank on my "things I value" list, but gotta draw the line somewhere. I just have a hard time fathoming spending $800 for an "upgrade" to an existing pain in my butt, if it still had problems, I would surely not have a pleasant reaction.

oh and about the room size,

11x12 = 132 dining room
15x12 =180 office
6x9 54 =foyer
17x16 =living room ( where woofer is located )
3x24 =hallway
19x10 =kitchen. All these measurements are rounded up a bit. standard 8 ft ceilings. no doors to close off any of these rooms.

With that kind of room size (cumulative 7,200 ft^3), order one large ported sub now and save up to order another down the road. For example, In your price range, PSA XV-15, or the Hsu VTF-15H (black).

Sorry about the incomplete calculations, I had someone at the door

132 = dining room
180 =office
54 =foyer
272 =living room
72 =hallway
190 =kitchen

=900*8 = 7200 cu ft as per previous poster. The mfw-15 is a large ported sub, I didn't think it was quite adequate, at least for the volume levels I like. It was enough most of the time, but I felt like I was running on the ragged edge and would rather operate somewhere in the middle. I am considering putting a french door on the office, which would cut off 1440 cubic feet of that. Not sure how much difference it makes. I would be putting the door in regardless, just for privacy.

I just noticed that PSA XV-15 is a bottom firing sub, how would having ceramic tile floors on top of concrete slab affect it, positively, negatively, or not at all? Never owned a bottom firing sub before

FYI, if you knock down any protrusions/bumps from the original screw holes and then use some foam tape as a gasket you can often rotate the driver so the screws are in between the original (screws at 12 & 6 o'clock). The cabinet will usually do just fine holding the driver with the new screws Kevin/Sandbagger supplies.

If you prefer to wash your hands of it, the other subs mentioned should do very nicely, and be much more capable than a dead sub. Eventually adding a pair of most any of the subs mentioned should get you what you are after.
