Designed to make your life easier, the BASSBOSS DiaMon-MK3 is a compact, high-output, point-source loudspeaker that can be used in a variety of applications including mains, monitors, or as satellites, and fills throughout a nightclub or installation.

The DiaMon-MK3 features a 1200W Class-D amplifier that delivers 900W to the 12" woofer and 300W to the 3" compression driver, which combine for a 50 Hz to 19 kHz frequency response and a maximum 126 dB SPL, plenty of volume for a small to midsized event. The coaxial configuration places the compression driver within the center of the woofer, which ensures phase accuracy for clear, intelligible sound at any level. A Neutrik powerCON True 1 power cable is included.

What's New
  • MK3 Amp Update—There are all-new amplifiers in the MK3 series. Total power has increased, and specifically, power allocated to woofers has increased substantially. The higher output voltages provide more impact. Universal input voltage compatibility of 90-250V provides more flexibility. Waterproof connections provide more peace of mind.
  • MK3 Enhanced DSP—The MK3 features an all-new 96 kHz DSP. The push-button presets have doubled from 4 to 8, and up to 100 presets can now be stored in the DSP and loaded via LAN. The comprehensive suite of processing includes meticulously tuned equalization, all necessary high-pass and low-pass filters, as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible.
  • ControlBASS Software—ControlBASS software supports an essentially unlimited number of possible BASSBOSS-developed or customized user presets which integrate seamlessly and coherently with all other BASSBOSS products for effortlessly perfect setups. The latest in DSP programming developments can be added via easy remote updating.
Advanced Coaxial Design
  • The cabinet is made from birch plywood, which is strong and solid, and the small size makes it veryportable. The small size is made possible by the use of a coaxial driver in a sealed enclosure. With the high-frequencies exiting coaxially through the center of the woofer, no extra space is required for the addition of a high-frequency horn.
  • The low and midrange frequencies are produced by a high-sensitivity 12” cone woofer with a 3” voice coil and a neodymium magnet. The same magnet is used for the 3” diaphragm high-frequency compression driver, the 1.4” output of which passes through the woofer’s pole-piece. The inner surface of the pole-piece is machined into the shape of a horn. The woofer cone is the continuation of that horn, making it possible to generate very high output from a very small total surface area.
  • The resulting coverage pattern is 80° conical, permitting a large coverage area and a great deal of placement options. A significant advantage of coaxial loudspeakers is the consistency of their off-axis response. Aside from delivering a more consistent and intelligible sound field, this also makes them much more resistant to feedback.
Advanced Power
The amplifier features a Class-D SMPS with PFC, providing two channels, 900W LF and 300W HF. Eight onboard presets allow for a variety of configurations at the touch of a button, and LAN connectivity allows access to virtually unlimited preset combinations.

Comprehensive Digital Signal Processing
  • Onboard presets provide a variety of high-pass filters to suit full-range operation through a variety of settings that maximize SPL when used with a subwoofer. The sealed enclosure provides the flexibility to choose between low-frequency extension or high-SPL operation from the same compact loudspeaker.
  • The proprietary BASSBOSS processing ensures exceptional sound quality thanks to its premium quality, high-fidelity electronics. Its ultralow noise CODECS, 96 kHz sampling-rate processor and high-resolution amplification are some of the finest in the industry.
Neutrik powerCON True 1 TOP
New to the MK3 are Neutrik powerCON True 1 are TOP (Total Outdoor Protection) waterproof connectors. Waterproof connectors and a totally isolated input connection section with waterproofed cones make the MK3 series able to be used outdoors without fear of what the weather will bring (or used indoors without fear of what the partiers bring).

etherCON Interface
  • The new DSP features an Ethernet interface that can be used to control the cabinets from a computer or to load software or firmware updates. The Ethernet connectivity in conjunction with the DSP onboard allows signals to be sent via Milan AVB. Firmware updates will provide access to this feature.
  • Within the software, multiple cabinets can be grouped together, allowing them to respond to commands simultaneously. This permits the levels of multiple loudspeakers to be adjusted together and yet independently from the levels of other groups of loudspeakers. In addition to individual and grouped level controls, presets can be loaded and signal levels and temperatures can be monitored. Each cabinet includes a two-port switch so multiple cabinets can be chained on the same data cable.
  • The MK3 DSP features a storage capacity of up to 100 presets, eight of which can be accessed at the touch of a button, with no need for a connected computer. The eight directly accessible presets are compatible with all the presets in the MK3 Top Boxes and are also compatible with previous generation tops and subs.

Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.
