- Parameters van topniveau om het geluid echt te reproduceren: de Douk Audio A100 versterker maakt gebruik van de modernste technologie op alle gebieden. Het nominaal vermogen bedraagt tot 240 W @4Ω in stereo en 315W @4Ω in mono, het bereikt ongelooflijk een THD zo laag als 0,002%, een SNR van 115dB en een SINAD van 94dB op basis van zijn krachtige functies en sterke flexibiliteit, ver boven andere.
- Exclusief patent voor warmteafvoer: integreert het koellichaam naadloos in de behuizing en vergroot het koeloppervlak aanzienlijk om een directer en efficiënter luchtstroomcontact te bereiken, zodat de warmte effectief door de behuizing wordt afgevoerd en de prestaties van de TPA3255 worden ontketend. In vergelijking met andere soortgelijke versterkers op de markt wordt de behuizing zelfs bij hoog continu vermogen niet duidelijk warm.
- Innovatieve en sterke speelbaarheid: met de schakelaars MONO/STEREO en BASS/FLAT ondersteunt de A100 vier werkmodi om zich flexibel aan verschillende scenario's aan te passen. De extra AUX-uitgang maakt het eenvoudig om alle subwoofers en luidsprekers te bedienen en alle meerkanaalsystemen (1.0/2.0/2.1/2.2/4.0/5.1...) op te bouwen. De A100 beschikt bovendien over de regelaars Super Bass en SW-FREQ, waarmee je de basversterking en de grensfrequentie vrij kunt instellen om een nog schokkender basservaring te bereiken.
- PFFB-ontwerp en optimale 4-laags PCB-lay-out: Post-Filter Feedback-technologie (PFFB) overwint effectief de gebruikelijke belastingsafhankelijkheidsproblemen van klasse D-versterkers, vermindert vervorming aanzienlijk en verbetert de lineariteit, frequentierespons, klankzuiverheid en systeemefficiëntie. Bovendien wordt een 4-laagse premium gouden printplaat gebruikt, die de signaalstabiliteit verhoogt en de prestaties en storingsbestendigheid verbetert voor een superieure geluidsweergave.
- Aangepaste 48V-voeding en hoogwaardige componenten: de meeste TPA3255-versterkers kunnen geen optimale prestaties leveren vanwege warmteafvoer en voeding. Douk Audio heeft speciaal voor de A100 een zeer efficiënte 48V-voeding ontwikkeld om de prestaties van de TPA3255 te maximaliseren. Bovendien worden Japanse Rubycon-, ELNA- en Duitse WIMA-condensatoren en zeer nauwkeurige potentiometers enz. gebruikt om een uitzonderlijke geluidskwaliteit te bereiken.

LUXURIOUS, just like it says
Color: White, Size: Queen (Pack of 2)
I used My Pillows for years which needed constant fluffing throughout the night until they just became useless. Since they became useless, I would always wake in the middle of the night with terrible headaches and my head would be sore all over, throbbing like a boil. I couldn’t stand anything to touch my any part of my head while these headaches occurred. One night almost a week ago I was awake in pain and couldn’t sleep. I started googling for a solution, a pillow that would support a human head, basically a bowling ball. After several products which kept sending me to Amazon, I stumbled upon this pillow. I read all of the reviews. Many compared it to a “luxurious hotel pillow”. So I waited and got them within less than 48 hours. It was a thin box so I wasn’t expecting much. They were vacuum sealed, I opened them and allowed about an hour for them to fully expand. They were comprised of memory foam and down alternative like “luxurious hotel pillows”. They were heavy too. I tried to fluff it for maximum feel. It was extremely firm and I wasn’t able to actually fluff or reform it in any manner really. I could feel the down alternative filling surrounding this semi hard center ( the memory foam I guess) and I fluffed as much as possible. I had difficulty getting it into my pillow case, which was fine to me. It just made me anticipate this perfect looking pillow. I had been suffering with these headaches due to inferior pillows, I couldn’t wait. I laid down and put my bowling ball head on it! It completely supported my head. I normally like my pillow to conform around my neck and shoulders to allow a straight alignment with my head. My head was slightly up, but hey this felt great!!! I could feel the down alternative filler cushioning my head with the firm memory foam in the middle. I could not wait to try it that night. Night comes and I’m excited to see if I can sleep through the night finally without waking with those terrible headaches. I slept almost all through the night except for going to the bathroom once!! And my head wasn’t hurting nor did it feel like a boil!! I was ecstatic to say the least. I know there are people just like me searching for relief. If you can tolerate a firm pillow you can’t go wrong with these pillows. You get two for a great price! I just wish I hadn’t wasted hundreds on My Pillows for all my bedrooms a few months ago. I will be replacing all the pillows in my home with these WONDERFUL pillows!!!

Love them!!

Ok I normally don't leave reviews but I had to on this pillow. I was looking forever for a pillow and was nervous about buying one because you know how that usually goes when it comes to buying pillows. They arrived compressed but when you unwrap them they blow up to be a heavy duty pillow. Firm but not too firm. I don't like super soft pillows that you can roll up in a ball with one hand, I like a pillow that gives support and these do just that. They are cooling as well they are pretty for a pillow with the unique design. If you are in the market for a pillow and reading this THEN BUY THIS PILLOW & come back to tell me thank you. I promise you will NOT be disappointed. No I didn't get paid to say any of this. I wanted to give a honest review where it deserves one! You will not be disappointed! Thanks for the fast over night shipping as well. Not to mention the pricing is on point. I can say right now you will not find 2 pillows of this quality & price.

Best pillow I’ve ever tried—hands down!
Size: Queen, Number of Items: 2
I’ve gone through a bunch of pillows over the years, but this BETU Cooling Pillow is by far the best one I’ve ever used. I sleep in literally every position—on my back, stomach, and sides—and this pillow works perfectly no matter how I’m laying.
It really does have a cooling effect, which I love as a hot sleeper. Just make sure your room is cool too, and it makes a big difference. It came vacuum-packed, but it fully expanded within just a few hours. I was able to sleep on it the same day it arrived, and it was super comfy right from the start.
I also washed and dried the pillowcase before using it, and it came out looking and feeling great—no shrinking or damage at all. Honestly, I look forward to going to bed every night now just because of this pillow. It’s supportive, comfortable, and totally worth it!
