    Re: Post the most beautiful builds you know of...

    If you do, pay more attention to panel vibrations than they did.

    The version we auditioned at RMAF were some of the most resonant cabinets I've come across. They were no where near braced enough.
    I have been thinking about the best way to build them for days.... It's enough to hurt your brain!!! I will definitely brace it well.

      How did you come to that conclusion?

        I put my hands on every enclosure I could while they were playing.

        Those particular models were vibrating more than any other set I put my hands on all weekend.

          I'll have to give that a try.

            Is there a particular part of the box, one should put his hands on, in order to feel the vibrations better?

                I typically use the back of my hand, tops of my fingernails, on the side panels. Even small panel vibrations are easy to pick up that way, and you don't leave fingerprints all over the nice finish.

                That particular model's front and back panels were really moving quite a bit. There's little doubt in my mind that the sound output from those panels was significant, as large an area as they cover.

                The concept and look are quite nice. But the enclosure construction is seriously lacking behind all the cosmetic beauty. There were other enclosures that large on display, without a hint of the obvious vibration suffered by these.

                  That's sad to hear because they look great. I thought they sounded pretty good too, although I only listened to one song on them.

                    And decent drivers to say the least. Bracing is cheap too . . .

                      Far as I know, they design that into the system. So it's intentional.

                      Kinda like leaving a tunnel behind a mid so it's sorta kinda open back-ish. As long as the response of the panel vibrations is properly accounted for in the design, and it sounds good...

                        Or they just account for it in the crossover so they don't have to re-engineer the cabinet. ;)

                        I just can't imagine that an enclosure resonating in the mid range and upper bass sounds superior to that same set of drivers in an inert enclosure, or sans enclosure altogether.

                            "Each wood layer is quality-graded and carefully oriented by density and grain for optimized performance and appearance. Additionally, a special sub-structure of reinforcing ribs is incorporated internally to virtually eliminate any spurious vibrations. The result is an enclosure of exceptional beauty and stiffness, free from undesirable resonances and coloration."

                            My emphasis. Depends on what your definition of virtual is. Maybe to them, it is the inability to see it flex with the naked eye.

                            Because it was obvious to the well placed fingernail that virtual means "not really" in this case.

                              At over 165 lbs, it seems like it would take a lot of engineering to make their cabinets resonate! ;)
