Floor-standing Speaker


           " I realize I have spent a great deal of energy to convey how much fun I have had with the Mark & Daniel Apollo IIs - but I hope my message would not be misconstrued... Somewhat paradoxically, the Mark & Daniel speakers are remarkably revealing yet possess a very friendly and somewhat forgiving nature. They are not all about hedonistic fun, either. These are some expressive speakers that will be the vehicle for some real musical appreciation for a long time to come." 

- John Potis, 6moons.com -





           The Apollo-IIa sound system is a large floor-standing speaker, designed and engineered by Mark & Daniel®. It is a truly exceptional system with stunning output capability and unparalleled high definition sound reproduction. The Apollo-II is designed to appeal to the most discriminating audiophiles, and is suitable for very large listening rooms and for general hi-end Home hi-fi applications.


           The Apollo-IIa is crafted as a two-way+ system (with one additional omni-directional super tweeter), featuring a low 600Hz crossover and super low Frequency Modulation Distortion (FMD) index. This large floor-standing speaker system employs the latest advanced concepts and state-of-art technology developed by M&D.


System Structure


           Each Apollo-IIa speaker consists of one newly developed M&D® DM-3a Dreams AMT driver, with a huge diaphragm 160 times larger than a conventional 1¡± dome tweeter! These Dreams drivers are carefully pair-matched for wideband reproduction, from 600Hz up to 20KHz --- over 5 octaves --- which virtually guarantees true high fidelity reproduction, stunning dynamic output, and super low FMD (Frequency Modulation Distortion) pollution, including to the most essential (800-4KHz) Mid Frequency band; the DM-3a Dreams driver enables the Apollo-IIa speaker system to cover the complete Mid to High Frequency band with one single driver. This is flawlessly accomplished without acoustics crossovers, without phase variation, without any LC compensation network.


           In order to achieve such unparalleled sound quality, a very powerful 10¡± woofer with stunning output capability, using M&D patented SX (Super Xmax) technology, is employed in the design of the Apollo-IIa speaker system. This outstanding low distortion driver accomplishes optimized Q-control from 600Hz down to 25Hz (system F3). This incredible achievement is due to the woofer¡¯s exceptional ¡À 15mm (1.2¡±) linear excursion, which allowing the Apollo-II to be operated even under very high Sound Pressure Levels bass reproduction.  



           Each complex Apollo-IIa speaker enclosure is hand-made and crafted from costly compound marble material (CAM). The cabinet is extremely rigid and heavy (each weighs up to 77Kg, or 170 lb) to properly handle the enormous internal pressures developed by the exceptional drivers.


           There is one DM-2a Dreams super tweeter installed on the top of each speaker enclosure. This DM-2a super tweeter incorporated with a 0dB to -6dB adjustable attenuator that located on the back panel have been wired internally in parallel connection with the DM-3a wideband driver, and both drivers are wired to the MF+HF speaker terminals of the enclosure¡¯s back-side. Featuring high power handling and low FMD reproduction capability, the DM-2a is mounted face upwards to respond only to music¡¯s High Frequency harmonics, from 7 KHz up to 35 KHz.


           Crafted from compound marble, an acoustics diffuser cone is placed on the top of the unit facing downwards to provide a 4¦Ð (360 degree) audio radiation pattern into the entire listening room. Listeners will no longer hear HF harmonics only from the speaker¡¯s tweeter, but additionally they will now hear many indirect reflections from the listening room. Thru fine tuning to the (0dB to -6dB) adjustable attenuator to balance, a more vivid and life-like music reproduction image throughout the very high frequency range may be achieved.
