    On another note, I thought .23ft^3=6.5 liters. Are you going to be too small if you take a liter to use for your mid and tweet? Maybe I missed something above.
    It measures out to 0.243 ft^3 net if you calculate the dims, but it's advertised as 0.23ft^3. Truth be told, the midrange chamber is NOT QUITE a liter the way it sits, and comes out even. Since I'm HPing above the point where rolloff becomes an inhibiting factor for the mid, it's not that much of a big deal.

    Good eye ya have there, but I did figure it out mathematically.
    Thanks,
    Wolf

    Okay- I'll post the rest then!

    And here she be! 16 parts for this one, because I had to kill the breakup from the aluminum cone, tweak for the different impedance woofer, and padd the Xenum portion along with a tweeter pad change to get it to look right. The 3.3ohm changed to a 4 ohm, and the 25 ohm changed to a 20 ohm. I was surprised I only lost a couple dB in sensitivity. Call this an honest 82dB.

    Meteorites:





    Resistor change in Xenum sector:

    Thanks for looking!

    Okie- Dokie! It turns out the Anarchy and DC160S-4 are not that different in terms of box construction. They both like the box with a 7.5" single flared port. This means the inner port exit has to be placed above the triangular midrange chamber. No biggie.

    I get Xmax range to 35Hz for the DC160S-4, and nothing beyond for the Anarchy8ohm, at an output of 100dB. The DC160S-4 loses about 2 cycles to a 64Hz F3, but F10 is now 40Hz (opposed to 44 before) with the stuffed arrangement. If the walls are lined, it may get more boomy, but the F3 is 59Hz, and the F10 is still about 40Hz- all with the longer port.
    I think I like the original alignment for the DC160S-4 better than these 2 that follow, but if you want to experiment with both:



    The Anarchy gains an additional 12Hz F3 for 50Hz result over the original's 62Hz. F10 is about 37Hz.




    Next up, a simulation of FR! I won't post the schematic unless EricH says its okay.
    Later,
    Wolf

    Very cool. Hope to hear them sometime.

    I'm open to the adaptation. I used the DC160S-4, as I already have them, for this one- but sure- that would be a dynamite little 3-way at a slightly less sensitive spot. 4/8 ohm? Spec sheet? (Edit- found it! The 4 ohm might be better in terms of sensitivity. I can only find the specs for the 8 ohm version.)

    I'm game for that...

    I'd like to call those the 'Meteorites', as they will have other-worldly impact and slam like no other in that size class, xenoliths are common in meteorites, and they also will be HEAVY for their size.

    Heehee,
    Wolf

    I ordered the 2 remaining coils that I required for this today.
    I hope to be assembling networks soon, and making the chambers for the mids and milling baffles.

    Later,
    Wolf

    Hah. I read the post like 5 times and still completely missed the mention it was a breakdown box from PE :D Gotta stop posting in the mornings.

    That's some big words in the subject.

    I have a design that looks almost exactly like this that I never showed to the public; same tweeter, and almost the same mid. It sounded pretty damn good, though. Maybe I should dredge it back up. I'm not sure if I could cobble it together in time for Iowa, but I'm thinking about it now.

    When I buy knock-down cabs, they get constructed faster.

    Josh- the cabinet from PE's part number is listed in the picture, so all you have to do is look that number up. I think it's 8.5" normally, but I added another 3/4" baffle layer.

    Later, and thanks, guys!

    Seriously Wolf, the designs never cease!! Though you are quite a bit further along than I, This design is quite similar to another I have just ordered parts for. Just as you, I am building a set of mirror-image 3-ways, the right and left utilizing the Rs180-4 in a sealed enclosure, along with the Xt25sc90, and the Rs100-p's. Eventually I plan to construct 2 pairs of these, for fronts and rears, building a center channel that adds a second Rs180-4. The center channel shall likely find the Rs180's wired in series, and flanking the Xt25sc90, and the Rs100p. I've already received a few sheets of the same Kaiser Aluminum 6061-t6 from SpeedyMetals.com, found in the Q' series. This will serve as the baffles for this 'quintet', and hopefully when I am able, a good deal of the cabinet of my high-end build. For certain, the crossover design and nom de guerre will be far more of the conventional variety, than those of our seasoned thread-starter!!

    Re: Extrapolated Theorization: "Xenoliths"....

    Looking nice! Was just curious though, whats the depth of the box? I've been staring at the first pic of the speaker diagram and can't figure it out :(

    I wish I had more funds to do another build. My wife would be so ticked though lol.
