PRODUCT PAGE: http://www.diysoundgroup.com/home-theater-speakers/cinema-10/cinema-10-max-kit.html Cinema 10 Max I'd like to thank Erich and all the people involved in the SEOS design (zilch, Audio Josh, Coctostan, Penngray, LTD02, etc.) SUMMARY This speaker combines the compact footprint of a 10" speaker with the incredible output of a comparible 15" speaker. It uses a seamless cross over to allow crystal clear mids with stunning accuracy. The dual woofer design constrains the sound in the vertical plane to keep unwanted ceiling and floor reflections tame, while maintaining smooth horizontal coverage across the entire listening area. Flexible placement, higher performance, crystal clear sound, cracking dynamics... All features of this speaker. Whether for the dedicated HT, or the serious living room, heck even an outdoor HT, this speaker has what it takes. All in a cost effective package. FAQ Q. What changed in this speaker from the old version? A. It went from the SEOS12 with DNA-350 to the SEOS10 with DNA-360 and received dual 16 ohm woofers instead of a single 8 ohm. Q. What is the impedance? A. Nominal 8ohms. Q. What is the power handling? A. 400 watts. Q. What is the max peak output? A. 125db @ 1m. For a typical 12ft listening distance, it would be 113db, although the room would provide an apparent SPL of about 116db. Q. What subwoofer XO do you recommend? A. Start with 80hz, but I always recommend measuring the results in your room with your sub(s) and adjust from there. Less than 60hz is not recommended. Q. Can I make the box smaller or bigger? A. The net volume should be between 40 and 60L, however this woofer is quite flexible to box size changes. Q. What should I use to stuff the box? A. I prefer polyfill or insulation. Line the walls with a couple inches thick, but be careful to keep away from the port openings. It's ok if some area doesn't get covered. Q. Is there any way to improve the performance of this speaker with a better compression driver or woofer or cross over parts? A. Not without a total redesign. Consideration given to the Elusive 1099. Similar performance and design for use as a center, but the dedicated midrange may offer a step up in clarity.
