    As long as the braces are opened up to transmit air flow, that should work fine if you don't stuff the bottom of the box. IMO/IME, stuffing the bottom 5-6" of a tower box is a good idea to prevent the column resonance, even if you lightly stuff the rest of the enclosure. If you do fill that area, you'll need to rotate the inner end upwards. If you have kids/cats/kittens and they play around these, you might want the inside end upwards anyway to prevent a toy or critter getting placed inside the cabinet.

    Later, and thank you for the condolences,

          Got these finished up a couple nights back. Won’t bother posting the MDF pictures as I won’t do the veneer until it’s warmed up and dried out here. I followed Wolfs floorstand dimensions exactly - MAN are these things better than I was expecting. They passed the volume test, they are clearer than I was expecting in the midrange and most of all they can punch you with bass if you want it. I have a reference ATC system that I chucked them into, and they will stay here a while as they are that fun to listen to. Very happy with what my Mrs has called the ‘snowmen’ as the driver arrangement resembles such. They will remain the lounge TV/music speakers after.

          If if someone could find the inductor at a cheaper price, I would seriously consider building the bookshelf version of these for the garage. Scratch that, I would definitely. Thanks Wolf, hats off to you on this fun, cheap build. I will post a veneered shot when I get round to it in summer. Happy to post MDF shots for anyone interested.

            I'm glad I finally built this one from my wish list. It seems others agree quite highly, and they are immensely fun! Glad you are enjoying them.
            Honest impressions compared to the ATC? I'm just curious...
            Pictures are welcome whenever,
            Wolf

              Erse sells the 16ga 2.2mH inductor for less than $15. I'm not sure why PE doesn't stock that one.

                Not much I have heard beats the clarity and magic of that ATC dome midrange. So the clarity doesn’t compare but I was still surprised by the zingers. The zinger bass isn’t as clean, but certainly has more punch and weight. The highs are probably a little more congested than the ATC as well. But not so much that it bothers me. The zinger is just so fun on the bottom end and has enough clarity that I am happy to use it as a TV speaker.

                I’ll be first in line for a 2.5 version zinger for higher sensitivity and SPL

                  While I'd be game for a 2.5-way, I'm afraid that the sensitivity won't be able to get any higher. The 2.5-way would have to have the woofers wired with series voice coils to be able to parallel the second unit and come out at 8 ohms nominal. So- I'd lose 6dB for a single in series wiring, and then gain back the 6dB for BSC via the second woofer- negating any benefit except maybe max output.

                  I even thought about a 2.5-way with the voice-coils wired with the 0.5 coil between them. It would essentially negate sensitivity benefit in the same way.

                  Not to mention that a dual SD215A-88 cab would be minimum of 2ft^3, and more happy in 3ft^3.

                  Later,

                    So the Zingers have been champs, even holding up being loaned out to a friends party, where they received about 100W continuous for about 8 hours. Got them back with one dust cap caved in and drink spill all over the cabinets (they were bare MDF at the time). Ive had life get in the way and never got around to finishing them. Replaced the damaged woofer, and with the time were currently spending at home I've finally got around to start finishing them. Here is one half completed speaker for your viewing pleasure. Still enjoy listening to these speakers blast hip hop, pop and rock. Such fun speakers. Thanks Wolf.

                      Cabinet #1 came out nice. That's Oak veneer? Beautiful! Not sure how you're planning on finishing them if any, but in my opinion, I'd try to keep the look as light as possible because they really look spiffy that way!

The 18AWG dcr is too high. All of this can affect tonal balance, and there were only 4 choices, IIRC, the last being a more expensive 14AWG ERSE perfect lay. I listed the best candidate for the job, and copper costs money.

                          Money aside would the 14AWG ERSE perfect lay be a suitable replacement?

                            You might get a touch more output from the woofer with the slightly lower DCR, but that would work.

                              I know you said money aside, but if you are seriously thinking about building these, have you considered ordering directly through Erse? The 16 ga 2.2's can be had for like $20 for the pair. You would save more getting other XO parts added to the cart as well. I typically just buy from PE but sometimes the components aren't available or the savings are just too great.

                                Also you can contact PE to see if they'll will special order for you. I was putting together crossover parts and wanted all Jantzen, except Audyn Cap Plus be tweeters. PE couldn't get me the Audyn's I needed but did get me all of the others. (I think I may have paid for shipping that I otherwise wouldn't have, but that was my choice and PE was great to work with a usual.)
