I decided I needed to "upgrade" my JBL B460 and eventually pulled the trigger on a new 2269H driver. It is quite the beast though in hindsight I probably should have ordered the 4 ohm 2269G version. The basic plan was to build something similar to the JBL Sub 18 to go with my DIY M2 clones.

    I built a CNC router kit a few months ago so everything was designed around the ~32"x32" cutting limits. As you can see from the photos, the CNC did lead to some excessively creative bracing. More photos to follow... IMG_20180127_170214703.jpg IMG_20180127_170230857.jpg

    1/2" baltic birch plywood used. I doubled up the plywood to make the cabinet solid. And heavy. Picked up some scrap 5" PVC pipe for ports. Duratex for baffles and bottom. Rosewood veener for tops and sides. The veneer was already cut for another project so I wasn't able to wrap it around the way I wanted to. This will be good enough for rock'n'roll.

    Now you can see why matching the top and side veneers was not critical. Given the size and location of the sub, it is going to get stuff set on it - drinks, tools, pictures, christmas decorations, and plants. 1/4" tempered smoked glass isn't cheap but it should eliminate any discussion of what is or is not appropriate to place upon my beloved sub.

    Power is provided by a Crown XTi 2002 which is good for about 1600 watts bridged into 8 ohms. I haven't spent much time time beating on them but should get the chance this weekend.

    Looks nice. Curious to hear you thoughts on whether it is a success.

    I've been busy replacing the carpet in the house which required the teardown and reassembly of basically everything electronic in the house....so I'm just now getting everything back in place, wired, and tested. Currently working on adjusting the gain levels and checking connections to get rid of a little ground hum. The sub amp is currently running flat (no DSP enabled) though the Yamaha YPAO was allowed to do what it does during set up. Need to eventually work in a high-pass filter around 20 Hz to protect against over-excursion on ULF content. Currently using 60 Hz as the x-over to the M2 clones. A quick test with the Telarc sampler cut of the 1812 Overture was lots of fun. I think there in no doubt that finding the finding the performance limits of the system will require a mic and hearing protection :rockon:
