    When did I restart this thread!? Well I got the cabinets finished so I could load them up and actually listened to the 2216's. One thing I did not expect was the in room bass extension. They are low tuned in 26Hz boxes so they should be rolled off but to my surprise I had real room pressurization all the way down to 20hz??!!!

    I was doing sweeps to look for issues with the cabinets. Fortunately they were rattle and buzz free. With a predicted F3 at 47Hz I was expecting them to crash quickly after 30Hz or so but they just kept on going! Have any of you had similar experiences with these drivers??

    Well that is actually a good thing I can always up them to 32Hz to see what happens easy enough to do just change out for a shorter middle section with nothing permanently glued up.

    In a word WOW! I dropped my Heil's on top and turned them on. Balanced them out level wise and started to play some tunes. These drivers really are something! I can see why they get such good reviews the speed and clarity is really something and they hit so damn hard!? Listening to someone just strumming guitar strings was a real eye opener.

    So a good day have to start the tops and find some more music to listen too!

    I have never experimented with the 2216, but in giving the M2 an extended audition, I was really impressed by that woofer. It is articulate, punchy, and dives deep into the lower registers. If I ever do another DIY project, Iíll likely play with a pair of them.

    Thanks for sharing the pics!

    I've always been fond of the beauty to be found in the aesthetic simplicity of the Crown PS-series' industrial design.

    Makes me think of the late departed Scotty Fitlin and Tom Loizeaux.

    Remember this one?

    Getting my tops built! Glued up the corners to the side panels and doing some dry fitting to make sure I have a close fit to the horn and determining the best way to put in a horn mounting panel into the enclosure. I really need to get some measurements of the 2216's in there enclosures to start working on a low pass filter in LEAP.

    I bet the Mg on that waveguide is going to sound amazing... and with that 2216, these should be a formidable pair of speakers!

    Thanks for keeping us posted.

    15" with Heil

    Rob,

    Beautiful build! Can you comment on the combo with Heil? Did you feel like something was missing jumping from a 15" driver straight to the Heils?

    Since I'm home these days, I was just looking through unused speaker parts pile and found a pair of JBL 2226H. I wonder if they would work well with Heils crossed around 1.1Khz/1.2Khz.

    Hello dkalsi

    Thanks! About the Heils I had them set-up with a pair of 12's and just stuck the new box under them. I am using an 850Hz 24db L/R active crossover with a notch to smooth the response. This woofer has a rising response so they are not really dialed in as well as they could be. They still sound very good so I don't see any reason why they would not work well with 2226's and some TLC.
