Is It Safe To Buy Dual MFWs? - Page 34

No. The Japanese ruler they used. See?

Is AV123 giving any type of warranty on these new amps? In general, what is the warranty specs on the MFW on the driver and the electronics?

In reference to the previous question of the testing of these amps.....when I talked to AV123 a few weeks ago, they claimed to have sent these amps to 3 reputable third party engineers that have tested and passed these amps with "flying colors".

Well, they ought to have sent them to three grammar school kids to measure them, don't you think?

It would be nice to have the findings of the three engineers released, preferably by the engineers. This is not a dig at you, but AV123. I personally don't trust them and would prefer to see the results as opposed to be told they did something and it worked.

Actually I prefer that with pretty much any company, regardless of issues or personal history.

Crap, I really should have taken a notebook with me yesterday as I was at their facility. They did send the amps and the subs to various engineers to test them. He gave names, but now I can't remember them. They mentioned having three containers full of parts that need to be fully assembled. Also, concerning the LS6/LS9 people waiting, I saw at least a couple of pair waiting to be shipped, and a couple of them waiting to be assembled.

I heard both the LS6's (they had some B-stock ones with only a scratch) and the new dual MFW-15's and both sounded amazing.

Did they have the LS6's paired with the dual MFW's? Trying to imagine how that would be properly set up but I'd love to hear either the LS6's, LS9's or the GR research version.

We heard the dual MFW's with their X-static 5.1 setup. It really made all the difference in the world. I wasn't really convinced on the dual sub thing until I heard it in this setup. One was right by our seating position and one was up front. We listened to the LS6's by themselves without a sub. I think we turned the sub on, but that was just extra candy, I think the LS6's would be just fine by themselves as they are designed. God they are beautiful... AV123 does one thing better than most, amazing finishes.

I should know in about a week or so when my long awaited LS9s arrive and are paired with my quartet of MFW15s.

LS-9's and Quad MFW setup!? I like this guy. I'll soon have tripple MFW's with the Rockets and I look very forward to joining the quad club.

Good God man! How big is the room?

KH....that's what I was thinking! LS9s with quad MFW 15s? That's a lot of huge speakers that need a lot of real estate. No doubt. lots of SOUND!

It's 19' wide, 24' long, and 8.5' high. It was designed by Rives Audio and is fully sound treated, including all walls and the ceiling. Each corner has a floor to ceiling bass trap. The walls are 5/8" double sheet rock green glued together.

AV123 had a sale on some B stock MFW15s back in February that were only available for local pick up (no boxes). Since I live less than an hour from their office, I jumped on the deal-it was too good too pass up. They haven't missed a beat, by the way. I located them nearly equidistant from the front row center seat, along the side walls. Although it's probably not necessary to have four of these subs to produce reference level volume in this room, it does seem to help even out the level at each seating position. Plus, the amps and woofer cones are hardly taxed.

We'll have to compare notes after your 9's arrive. I've had mine for a few weeks and can safely say they are, overall, the finest (and final?) pair of loudspeakers I've owned in terms of sound quality. Other speakers I've owned include (but are not limited to) Martin Logan, Thiel, and Magnepan. I'll provide a more detailed opinion of the LS9s in a separate thread.

On a related note, I'd like to pay tribute to MLS. The LS series are capable of prodigious bass output and I was getting too much of it due to a combination of the speaker's response and my room. The LS' have a passive bass management system to address this issue but I was not familiar with it so I asked MLS for help. Though he easily could have provided the information required via email or telephone, MLS offered to visit my home personally and make the adjustments (~ 50 minute drive). He did so yesterday, and I'm grateful for his support. We also had a great chat about the AV industry in general plus other topics of mutual interest.

FWIW, I have two MFW-15s on order and look forward to their arrival soon.

If your LS9s sound anything like mine, I think you'll discover a new appreciation for your bass traps .

I happened to talk to MLS yesterday, and got my 'promised' LS9 delivery. Usually Mark is very talkative, however he quickly informed me that he had to go to a new LS9 customer's home to address bass issues!

There is an active thread for LS6/9 owners over at the Tweak City Audio forum. It's under the 'Adult Swim' section.

O.K. Sorry for the thread jack.

Thanks for the link. I'll definitely take a look.

Unless it's too much of a hassle, could you post some pics of the room after you get them? I'm really curious how the whole setup fits together.

For what it's worth... I picked up three. Had to burn up some prepaid bmf credit... I have a good feeling about these. Call me crazy if need be. Hopefully they get it right this time around. The products I've gotten from them thus far have really impressed me, even before factoring in their low cost. I look forward to getting these set up and hope for many years of happy thumping...
