In 2009 ha friend helped me costruct and have manifactured a 3-way dynamic dipole system with closed box subwoofers operating below 45 Hz. The dipoles themselves operate below the dipole peak up to appx 6 kHz where the tweeter becomes too large and beaming starts. We have to thank Rudolf Finke for his work on this way of thinking dipoles: A small baffle or maybe no baffle at all, trying to make the radiation pattern as close to a theoretic dipole as possible.
Left main speaker in the nude. Two Beyma 12" in a small H frame, two nude SEAS W15CH and one nude Mundorf AMT2340. The pic is from before I replaced my Yamaha WXC-50 and Squeezebox Touch with the Ultra.
Old pic from the rear wall. As you may understand I do not use the Ultra HDMI. Listening position pretty close about 1,5 m from the speakers. 10 cm acoustic tile above the listening triangle. Large distance to side walls, 1 m from speakers to front wall.
I use a Topping L30 headphone amp instead of the onboard one. I also use a Cambridge Audio Alva Duo instead of the onboard Phono amp.
My turntable is a modified but you cannot see that German treasure from 1973 with a new Bokrand tonearm (my father bought the record in 1963 or so).
Details above. I've always used class D amplification and DSP crossovers/eq. To use something else you'd have to be dipole hero Siegfried Linkwitz. Until MiniDSP came along with their Flex Eight I had a PC running the filters under Console and a RME Fireface UD sound card. That PC is now running LMS for the setup. Peak volume in the listening position is a Mahlerian 108 dB(A).
