    Anybody know how big these are? The multiple resonate (sic) chambers sound like the Hegeman designs, which go way back in time, coupled with the bending wave tweeter. But I don't think the cabinet looks big enough to allow adequate wave length for low bass resonance. So maybe that's more "moo-doo"? Or is there hidden DSP?

      Admittedly, I have yet to graduate up to the 'good' woods and often use pine from the local lumberyard, but I like the look of poplar. As far as looks go, with some proper stain I'd pick it over some oak and maple; the poplar has more character. Beauty is in the eye of the beholder. With that said, I'm not a fan on how they used it. It reminds me of Darth's helmet.

        I really like how you made that square frame woofer look like a "Roundie."
        I think Chris Roemer had a thing of painting a round black circle to hide the ND series flanged faces too. Hid it pretty well.

        Them's good looking speakers!

          Moo-Doo is a local brand of bagged, fully composted, bovine excreta.
          But our dairy farmers keep it in a slurry to pump it on their fields.
          They call it 'honey', and the open tanks they transport it in are 'honey wagons'.

          One of our local characters was insulted by a shopkeeper for smelling like 'honey' when he came in the store - the parking lot was below the road, so next time by with a load, he took the turn rather fast when he saw her car beneath him........good old Phil!

            Thanks Thomas but ...

            they probably look better in pictures than in person. I only have the capability and know how to cut a circle, so much for that. Left the woofer recess rough knowing it would absorb the dark stain and turn almost black. Same with the tweeter so any part of the recess that isn't covered by the driver sorta blends in.

            Maybe someday I can finish one of the smaller projects and make a meet.

            davidB Good story.

              Correct question: Has anybody heard these? Don't judge a book by its cover.

                As a cabinet maker's son I can attest that there are many different grades of poplar. Grades of poplar you wouldn't want to see the price tag on. It's not all the same. There are beautiful grades of poplar on this earth and really it's in the eyes of the beholder.

                  Very true about not hearing them but c'mon if Wolf is correct about the drivers I don't see a sonic breakthrough here. Now cost I never argue that point because diy/commercial is impossible to go apples to apples. The sales literature sure takes some poetic liscense. But hope they do well.
                  BTW does that tweeter fall under Bending wave technology like German physiks or Ohm F

                    The German Physiks and Ohm F I would not call a bending-wave. Why do you call them that? Also, FWIW, I've heard the big dealio GP at AXPONA, and they are just dead above about 7k with nothing past there. The bass module did not dig very deep either.

                    The Tectonic Elements/Hi-Wave drivers are hybrids of sorts. They have a conventional motor for the bass range, but the mid to high is more of an excited bending wave driver.This is just according to what the company says it is.

                      Ben, I can only repeat the claims of the Mfg, Ifyou research the German Phys website they say multiple time "based on" tech from the Ohm driver
                      which was called and still is bending wave tech. Also I think Jordan claims to use the tech, so if I am not using the term properly sorry. I do not know anything about the BMR units.

                      Edit Also research walsh driver, Ohm f driver, German phsy. DDD driver,Jordan bending wave driver

                      Also where the term came from Walsh Driver

                        BMR from tectonics are basically exciters/dml with higher excursions meaning they have more pistonic motion to increase bass response while the mid to high frequencies act more as a modal or bending wave motion.....Most exciters cant go lower then 50hz due to limited excursions......some designs use both bending wave drivers combined with conventional pistonic drivers for the best of both worlds like the high end Gobel design. https://www.youtube.com/watch?v=YOy4XmVICRw&t=19s

                              I would substitute Pine
                              Where I live Poplar is seen as a bit expensive, but not high priced.

                                I'm sorry, but that is a DC160 and a Tectonic Elements 2" driver.
