I recently picked up some Anarchy-704 woofers as I had always wanted to try them out. Wanting an easy build given the current MN weather, I figured they might work well in some BR-1 cabinets I had on hand. I went searching for a 2-way design that utilized the 704 and came across the Anarchy-XT. Mike from AmpsLab was kind enough to provide the crossover and cabinet layout. I ordered the required crossover components, which there are many, as well as a pair the XT25TG30-04. I haven't heard the XT25, so I'm also excited to give it a shot.

First things first, the Anarchy has a larger frame diameter and depth than the DC160-8. To be able to route this recess larger, I built a crude jig from scrap wood and lucked out and no cutting was needed. I removed the terminal cup and used the upper 2 screw holes to attach my jig base. To that base, I attached a piece of scrap plywood perpendicular to the baffle. To get the jig face flush with the baffle I found a few more plywood scraps that just barely fit into the current driver cutout. When I attached these to the jig, I spread them apart so they would contact the current driver cutout and stabilize the jig. I kept the current baffle gap between the tweeter and woofer recesses and drilled a hole for the router circle jig at the center of the new recess for the Anarchy. I measured the recess depth difference and found I needed to cut down an additional 2.5mm or so. Removing the terminal cup also allowed me to fish in a clamp to secure the cabinet to the table when routing. Here are some pics of the process: -
Nice Job SilverDude . . .

Nice work putting them to use! Nothing like the whirl of cold air coming from a spinning router in the winter.Comment

The XT25TG30-04 can be a wonderful sounding tweeter. One of my favorites actually. It just takes careful crossover design work to make it sound right. Is the AmpsLab crossover public?Craig

The XT25 is 1.3mm deeper than the current recess which is also ~6mm wider than the XT25. I didn't feel like making another router jig, so I printed a chamfered trim ring.

Super impressed with how successfully you were able to recycle the cabinets. Will you be taking measurements? I too am curious to see how the Anarchy performs.Comment

One complete! I utilized some recycled cotton insulation that comes packed with items in the mail. I lined the sides and part of the bottom around the crossover. I also added a softball sized ball of Acousta-Stuf behind the woofer. Note that in the images below, the crossover board seen is just for the woofer. The tweeter circuit is mounted to the cabinet side near the top. I have not modified the BR-1 port at this point. Here is the impedance sweep of the speaker. Thanks for any feedback you may have on the graph. I'll try to get a frequency response measurement in the future.

Nice looking phase graph and easy amp load - the speaker looks good too - I need to get on mine soon . . .Comment

That trim ring looks amazing! I've never wanted a 3D printer until I saw that.Isn't it about time we started answering rhetorical questions?

Second speaker complete...well almost. Just read my assembly notes above and realized I forgot the Acousta-Stuf. I'll fix that soon and run an impedance sweep. So far they sound great. I'll have to play more familiar tracks, but there have been a couple moments so far where I heard subtleties I didn't before. Thanks to Mike from AmpsLab for the design!

Acousta-Stuf added and impedance matches that of the other speaker. Had them playing most of the day and I really enjoy them.Comment

Great job, SilverDude!
How does the midrange sound?
