Small, efficient and uncompromisingly stable - the M ONE X is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE X a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel. And for even more output power, two M ONE X amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.

In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.

  • Small footprint Class D amplifier with up to 1,180 Watts RMS output power @ 1 Ohm for easiest combination with all 2 x 2 Ohms subwoofers connected in parallel
  • Start-Stop capability down to 6V supply voltage
  • Smart highlevel input with ADEP circuit and Auto Turn-On function
  • Integrated, active crossover with lowpass, bass boost, subsonicand phase control
  • TwinPower Link for connecting two amplifiers in bridged mode
  • Bass remote control for volume adjustment
  • Low heat dissipation thanks to extraordinary efficiency

 

Special features:

Smart highlevel input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appear - but not with the M ONE X.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability
The switched power supply of the HELIX M ONE X assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.

Holy Grail
Color: White, Size: King
Holy Moly!!!! Ummm where do I begin?? Let’s start with how soft and delicious these sheets are right out of the package. I literally had 2 day old sheets on my bed and I couldn’t wait to wash these sheets and put them on my bed. I’m normally a percale sheet lover but even 2 years in, they are too stiff for me. I have other Bedsure products so I decided to buy these bamboo sheets and I’m so happy I did. The quality is unmatched, they are cooling, soft and very very comfortable to sleep on. They fit my mattress amazingly, even with a mattress topper and protector on it. They do take a long time to dry on low, per the instructions, but chat GPT assured me that it’s actually a good thing because the materials are high quality when they take awhile to dry on low. The last 10 mins, I did bump the heat up to medium and watched closely and took them out immediately and there were zero wrinkles. Chat GPT also said no fabric softeners or dryer sheets to preserve the fabric with no pilling and to keep the cooling effect that the bamboo offers so keep that in mind. I’m obsessed with every single product this company makes and these sheets are no different!!! The price is amazing for the quality too!!

Best sheets
Color: White, Size: Queen
I have bought, like many, at least 2 sheet sets per year, either because of substandard quality or by not meeting "Cooling" promises. I learned along time ago that "You get what you pay for" especially with sheets. All the Ross, Marshalls and Burlington sets that look to be great deals because they have to be,? they're at discounters and sure to be half of what they normally sell for, right?? I took a chance when I noticed these for $139 (Queen, 1 year ago). I had a set of the Maloufs Rayon from Bamboo queen sheets that I adored, $159, but after just a dozen or so washings they literally got holes in them. I trim my toe nails so that I don't punture the sheets, had to learn that the hard way. Malouf said that my top loading wash machine was adding to the issue!!! I don't walk around with any holes in my wardrobe and I wash everything in the same unit. Any way, I took that chance and these are the BEST sheets I have ever purchased, period. I ended up with a hole in one set and Bedsure provided me a hefty discount/refund on my next set. These are very smooth so if you are sensitive to the feel of certain materials, you will be very happy. They don't have that cheap Microfiber Sheen that you get with other sets in this price range. They keep me very cool, and I'm a true hot body. Buy these and I assure you that, for the money, I don't believe there exists anything better... Enjoy

Good quality sheets
Color: White, Size: King
Really lovely sheets! Just the right thickness, not scratchy and fit our deep mattress. Have washed these a few times now and they get softer. No pilling thus far. Great buy!

Wrinkle easy
Color: White, Size: Queen
These are so comfy and cooling I love it. Such a luxurious feel. But they wrinkle so bad. I think it’s the rayon, but that’s what makes it so comfortable. If you’re willing to iron sheets or are ok with the wrinkles these are perfect!

Cool to the touch
Color: Sage Green, Size: King
These sheets are nice but in my opinion they aren’t worth more than $100. Side note, finding goose down inserts are challenging to find in the 20x40 pillow case they provide. So keep that in mind. The goose down pillow size I’m most commonly seeing for a king size bed are usually 18x36. That is more my fault for not double checking. They do feel cool to the touch which I do appreciate.
