It might be somebody from the DIY Audio Forum,

I'm aware they have build M2 clones and have the PEQ/XO files available for download. You can save a fortune by not using the Crown amps for the M2 not to mention the boxes. Pretty cool, they even have the part numbers for the M2 badges if you are OCD like that.

Thanks for posting the video, now to get a 3D printer and CNC milling machine.

Wow that's an extremely good process and equipment list that guys has. But the realist in me wonders what the spreadsheet on equipment costs versus just buying the speakers looks like, hahaha. I'm guessing if you add up his table saw, CNC mill, 3D printer costs that a person could buy about 3 pairs of real M2's for the same cost.... all the while exerting much less effort.

What's funny is after going to Axpona and hearing the JBL's vs some 300,000$ priced speakers the jbl's sounded the same if Not better. Once your at a certain price range let's say 50k and up the difference between speakers is really hard to tell apart at least it is for me.

I can help you out,

I'm passing through your neck of the woods the first week of July to visit my brother. That will give you time to build your M2's and I'll pick up your old Titan 615's and Infinity 1260 subwoofer drivers.

I'll hug 'em, kiss 'em and call the George if that helps!

Yes, I will go out of my way to get rid of your old stuff because I'm cool like that.

Very nice build, it's an interesting question of, are these m2's? I think over time more M2 parts will come up, but today I'm not sure the sum of the parts is equal to the whole factory JBL product. I would say the cabinets are nicer than factory.

Couple of observations, first I think that builder is probably from europe or possible the northeast US based on the rocks you can see in that back wall of what is probably a basement. Second that hard part would probably be figuring out the crossover layout, it appears he is using a genuine JBL woofer, but you could probably source a similar performing woofer somewhere else. The box is nothing special, VERY well built and WAY beyond anything I could ever hope to do but fairly simple. Very cool build none the less.

That honestly surprises me. I would not expect $300k "hifi" speakers to be up to the level of the M2. Typically speakers in that price range are voiced by ear and sound pretty bad.

Some sounded good and others ehh were just ok and made me feel good with my choice if the diysg Titan speaker kit. The team of people behind JBL speakers as hole is pretty amazing. Hopefully one day I'll be able to clone a M2.

Not me. I'll just wait 'til Beast sells a pair.

Helluva nice build on that DIY version. They look fantastic, and hopefully sound as nice as they look.

Wonder what the D2 compression driver in the JBL M2 goes for, price wise? What is the model number and price of the waveguide used in the M2?

I got some at $290 a while ago, but I think they raised the price. I like the 2453H-SL better than the D2430K, however. Those can be had for like $270ish.

I thought Beast was rocking the 4367. So you might have to wait for him to replace those with the M2s and then wait for him to swap out the M2s for something else. Shouldn't be that long of a wait.

It is $1600 in drivers and horn. Not sure if you need the flange as well. You still have to have a crossover whether active or passive. Most people don't have the knowledge/equipment to design a passive xo. Add that to the cost. I would guess one would have around $2000 in parts before starting the build.

What is the cost of the passive M2? $8k?

The woofer is ~$200 cheaper at ProSoundService. The crossover for the passive version including binding posts is also available.

You're somewhat of a legend for the amount of speakers that have been in your possession. The board is always watching.

There is no passive version. That's the protection caps/highpass/pad for the CD.

I bought BSS BLU-50 from an official dealer, needed for JBL-M2 processing, but it can't be detected from home network router (ASUS RT-N12+).

Should it work on my router or it requires a switch with PoE+ support or some other kind of connection device ?

Please help me if there is anything else that is important for connecting BLU-50 on a network to load processing files ?

I highly doubt he bought all that equipment and built a shop just to make 1 pair of M2s.

The M2 really is the sum of all of its parts. The woofer, waveguide and CD are all top notch components. Mix in the DSP processing done by those who really know what they're doing and it's no wonder it's a winner. Can it be matched using different components? Maybe, but you'd spend way more buying/testing vast amounts of parts in order to find out. There is no passive crossover in the M2, aside from the CD protection circuit.

Eh, I disagree. I think the 2216nd is great, but I think there are better CDs than the D2430K. The DSP is fairly basic and the amps are meh. The xo circuit also has an L-pad, and the positioning setup is prone to floor bounce cancellation. You can see on audioheritage the people cloning these using better CDs and more advanced electronics. The waveguide tech I think is the most special part of the M2. It's a great speaker, don't get me wrong, but it's not the end-all. Just my $0.02.
