- M&D Diamonds still sparkling -

              I recently upgraded my system to all digital The Diamond+ speakers are still completely outstanding! Amplification in the digital domain gives even more immediacy to dynamic (volume) changes in a performance and the M&Ds respond outstandingly to this.

             A friend who used to be a drummer was particularly appreciative of the Dreams ability to render cymbals without excessive harshness or brightness.
I guess you know they are good Still, I hope its useful to hear from a satisfied customer.

- Paul Vinogradoff, Pajama Ltd, London -         




             The successful development to Maximus-Diamond+, as his first representative speaker on the premium Plus(+) series product lines; Mark & Daniel is again, demonstrating to the world that he has accomplished another major achievement with leading technologies to hi-fi industry.


After long research, having uniquely developed the super-thin diaphragm craft on his Dreams-a drivers and incorporated the new QMA design on the SX woofers, the Maximus-Diamond+ speaker has proven how a bookshelf speaker is possible to create a true, huge sound and unparallel performance within a tiny body; a great innovation by M&D again, to challenge the mission impossible!


Only one-half thickness over the conventional substarte materials, a 0.0125mm super-thin polyimide (Kapton) as new diaphragms substrate has been sucessfuly crafted to consititude the DM-4a Dreams AMT driver. Due to the lighter moving mass of ribbons to Dreams-a diaphragm, transit response and detailing resolution may futher be improved; on the other hand, this substrate with higher compliance to the pleated diaphragm has also significanly extended the low-end frequency response of Dreams a big step down; the two-way crossover point has been dropped from the original 900Hz down to lower than 700Hz!


Ranged from 700Hz up to 25KHz, amazingly for over 5-octave wideband reproduction has been achieved by this single DM-4-a driver on Maximus-Diamond+ speaker! Uniquely low 700Hz crossover point on this two-way bookshelf speaker is not only further aparting from the most sensitive (800Hz-4KHz) mid-frequency range for human ears, but also significantly helps for a low FMD (Frequency Modulation Distortion) reproduction to the incorprtated SX woofer. Maximus-Diamond+ is therefore, capable to reproduce the sound with absolute transparency and clarity that audiophiles have ever been experienced, upon such a samll speaker!




On the other hand to the new 5.5 SX woofer with M&Ds uniquely QMA (Quantified Magnets Alignment) design, having definite unparellel 12.5mm (1) Xmax excursion, the SX5.5q-1.0 woofer has been assembled onto Maximus-Diamond+ speaker; a stunning deep bass reproduction on amplifude (under very high SPL output), frequency (for system F3 down to an amazing 42Hz), and full Q-control (along with the complete excursion range) have been optimized.


A 12dB/oct crossover network for perfect matching with these outstanding dirvers has been painstakingly designed for Maximus-Diamond+ speaker; essential elements such as the large Gauge 15 coreless inductor, audio-grade FPP (with 0.06% dissipation factor) coupling capacitor have been incorporated on the crossover PCB for fulfil best system demands.




Maximus-Diamond+ has the dimensions: H29.2cm (11.5) xW18.0cm (7.1) xD21.3cm (8.4); a rein-forced compond marble enclosure with the diamond shaped panel for effectively reducing the diffractional sound interferances and for aethetic design, is extremely solid and heavy that each weighting 10.2 Kg (22.5 lb). The nominal impedance is 3-6 ohms with average efficiency being 83.5dB/2.83V/1m.


Maximus-Diamond+ speaker has equipped an iron grille on the panel for proper protections to the woofer; due to the high openness to the grille plus the woofer is only working to the mid-bass ranges, the influence to sound reproduction by the grill is negligible. Therefore, the grille is not necessary to be taken out from the panel during auditions.


For proper operation, a high current amplifier with 100 Watts output per channel connecting with the bi-wire cable is the minimum requirement for driving the Maximus-Diamond+. For better sound performance and cost saving, two mid-power (35-60 Watts) amplifiers can be configured as the bi-amp playback system, is recommended by M&D.

            This special version Maximus-Diamond+(Dir) speaker, it has no difference with the standard Maximus-Diamond+ speaker in the general structure and specifications except without the crossover network built inside of the enclosure; this two-way system, the DM-4a Dreams driver and the 5.5 SX woofer have been directly connected to the bi-wire binding posts at the back side of speaker.


Maximus-Diamond+(Dir) speaker is therefore, a very good choice for sound up-grading project such as to be connected with your own external crossover network, with the active crossover amplification system, or to be directly linked with the advanced DSP system for loudspeaker correction in different environment.
