    The Gate, 4 tower open baffle active speaker system

    (english, as I can read and speak German, just not write it decently )

    Presenting my (currently raw) build here as well as it's a complete Visaton based design. I prefer using single brands and the high end units have proven themselves in Visaton's own designs. Living in the Netherlands means getting Visaton is also a convenience.
    I wanted something that would not only rival Siegfried Linkwitz' Orions but also trump them in full range output.

    Mains: 3.5 way WWMT/TMWW, 190x28x28 cm, part H, part (shallow) U frame,
    2x G 20 SC, 2x TI 100, 4x W 200 S, crossover points (LR 4th) 2300, 243 Hz with top and bottom woofer rolled off 30 dB at 243 Hz/12 dB slope.

    Subs: 190x35x35 cm H frame, 6x W 300 connected per 3 in parallel, crossoverpoint (LR 4th) 50 Hz between mains and subs when in use, otherwise the mains run full range.

    Planned finishing: all edges rounded, front and inside behind mid/tweeters white felt, complete frames high gloss white paint.

    Processing: Behringer DEQ2496 for room equalizing, connected with digital out to 2 DCX2496'. Outputs are configured for sub, sub, low, low/low-mid, mid, high and time aligned.

    Power amps: (per side) 1x Behringer EP4000 in stereo for sub, 2x Behringer EP2000 for main (all with combined silent fan and resistor mods).

    This speaker system isn't shy about reproducing the cannons on Overture 1812.

      Yes, no WAF involved in this at all.

            Very impressive...

            The concept of open cabinets is new to me, is there a way to simulate that?

            What is the advantage of a open frame cabinet?

                The links Rudolf posted were where I learned more on open baffle when I started thinking about building my own speakers.
                I also found a link through Google on how to simulate OB with Boxsim. Can't find the link quickly but it might have even been a post on the forum here.

                What is the advantage of a open frame cabinet?
                The advantages that made me decide on OB were no dynamic restriction by the (partly) sealed air mass behind the cone, no reflections from inside the cabinet going back through the cone, and the added depth to the soundstage by the reflected sound from the wall behind the speaker.

                To be fair, the disadvantages are the requirement to have the speakers at least 1m from the walls and to reproduce bass more cone surface is needed (or higher xmax).
                The 20 woofers I use are more than enough to provide deep bass (the mains alone provide enough bass at reasonably loud levels).
                Both of these reasons were no issue for me so I could go all out on this build.

                        The only good box is a no box.

                        I think I just made a marketing pun for Visaton.
