Looks mighty sweet! Did you ever consider having the woofer in its own separate module? Makes it easier to move, I guess. Also improves isolation of TM from woofer vibrations, if you can use some kind of decoupling material between the two enclosures..

Those look super nice! Can't wait for further details. Thanks for posting the jig and cutouts. I need to do an SEOS cutout shortly hopefully they turn out as good as yours.
I did, at one point I planned on making the sub separate, but the more I got into planning the more I wanted this to be a mightily present, classic set of floor standing loudspeakers. I'm really excited at how they're turning out.
For me seeing the speakers is a huge part of the listening experience, not sure how many others can relate to that, but seeing the sound come from a particular type of speaker and configuration is very satisfying.
The enclosure is extremely well braced. If I want to do more with bass I'll build a PA460 based superset subwoofer that I can place elsewhere in the room but I don't anticipate that being needed as these Mag 12's model really well and come very well rated.
Thanks!
Thanks glad you're enjoying it!
For all the circles I use a Jasper circle jig, I have the 7" and 18" version. Like this
For the larger size roundovers Magnate makes awesome router bits available on Amazon.
HTH!
Thank you!
Do you cut circular holes with a 90 degree cut and then apply the round over? If so, how do you do that? The Jansen needs a center pun in the middle of the circle that us now air...
Got some more work done today after I snuck out to the garage =)
2 hours of orbital sanding and wood filler and these things are as smooth as a baby's butt, final pass with 220 grit. Then lots of vacuuming and cleaning.
Back in the garage waiting for some more work. Next step will be a recess in the back for binding posts, some "flying buttress" style feet and then keep for stain.
I'm mostly decided in red stain but still not 100%

Little more progress today!
Started on the flying buttress feet, made from 3/4"X1.5" solid maple.
I cut 4 12" pieces and cut each end at 60 degrees
Then I put a 1/4" roundover on each side
I then cut them to 7.5" long and sanded them smooth with 220. Then I put two 1/4" dowels in each one.
Then using some center punch reference tools, I made transfer marks onto the enclosure
Each foot was fixtured in place using this jig I made
Feet in place, I will stain them a different color then glue them on before poly goes on.
Also put a 1/2" recessed for the binding posts, there will be 3 pair each side.
Using a router template I made I positioned this on the cabinet then routered the area out
On the backside I added another layer for the binding posts to pass through and give sufficient thickness
Here is where they stand, I'll do a little touch up sanding and then she's ready for stain! Getting excited to hear these beasts!

Did some final buttoning up last night!
Faitalpro 8" midrange
Internal binding post wiring, M6x1 nylock nuts with nordlock serrated washers
More damping
Bolting in the drivers
They are done and in my audio room, more pictures to come, I've been tuning them and they sound incredible!

Nicely done. You'll have a hard time topping the overall performance you'll get with these.
Please post some measurements when possible. Thanks.

Ok had a chance to take some nice photos today and spend some time with these.
There are few things in this world that match the satisfying feeling of finishing a set of speakers that you've been envisioning and thinking about and building, then staring at them and listening to them.
I am on cloud 9 right now just looking at, listening to and tuning these things.
I will write a listening impression after this and post up tomorrow, but I have never built or listened to a pair of speakers with the effortless speed, efficiency, power, attack and detail of these things, just wow!
And after about an hour of tweaking this is where I stand, measured in room from the listening position.
Cross over points sit here currently:
Horn - 1500 24db
Mids - 2000 24db, 80 24db
Subwoofer - 100 12db, 20 48db
The asymmetrical points between the mids and sub helped address some FR issues w/o any additional EQ which was nice.
Also have a 5ms delay on the left subwoofer which helped with some room issues tremendously. Mids needed the most work to smooth things out especially in the 100-400hz range where there is a lot of room stuff going on.
More to come, hope you guys like them, please let me know your thoughts!
