ESX QL800.8 - 8 Channel AmplifierCompact QUANTUM amplifiers in Class D technology have been the spearhead of the ESX range for years. The range extends from the 4 x 300 watt RMS QE1200. 4, which won an EISA award, to 1 ohm stable mono blocks, to the tiny QS TWO , which can fit anywhere. The large selection allows many possible combinations. But that's not all: ESX is now expanding the Quantum range with two more Class D multi channel power amplifiers, which offer a whopping 6 x or 8

Compact QUANTUM amplifiers in Class D technology have been the spearhead of the ESX range for years. The range extends from the 4 x 300 watt RMS QE1200.4, which won an EISA award, to 1 ohm stable mono blocks, to the tiny QS-TWO , which can fit anywhere. The large selection allows many possible combinations. But that's not all: ESX is now expanding the Quantum range with two more Class D multi-channel power amplifiers, which offer a whopping 6 x or 8 x 125 watts RMS at 2 ohms, top sound and the most modern features.

In this context, the new models of the QUANTUM QL series occupy a special position in the ESX range. Ideally, 6- and 8-channel amplifiers are configured so that they do not drive power-intensive 12- or 15-inch subwoofers, but rather develop their potential on 2- or 3-way systems. ESX multi-channel power amplifiers are designed to use the many channels and setting options to optimally supply tweeters, midrange speakers or woofers. In this configuration, they have significantly higher performance than might be assumed at first glance - specifically up to 160 watts RMS per channel. How is that possible? Very easy! By actively distributing the frequency ranges across multiple channels or speakers in the vehicle, all speakers never play at full power at the same time. In this case, the amplifier uses the power reserves of the generous power supply, which all channels can access if necessary. ESX calls this feature Dynamic Headroom Technology, or DHR for short.

If you decide to use, for example, four 2-channel models instead of an 8-channel amplifier, the DHR function or the dynamic performance gain would not be possible. This is because the power supply of the first amplifier is not able to also drive the channels of the second amplifier. Seen this way, 6- and 8-channel ESX amplifiers have a dynamic advantage in multi-channel applications.

If, for budget reasons, you still plan to provide a complete sound system for the vehicle, including a subwoofer, with just one Quantum power amplifier, this is also no problem thanks to the equipment and the ability to bridge all channels. It's even possible. Control the bass level via a wired bass remote. We recommend the bridge of channels 5/6 with 250 watts of mono power for the QL800.6. The QL800.8 can do even more, thanks to the copy function it can provide 2 x 250 watts RMS at 4 ohms on the bridged channels 5/6 and 7/8 including bass control. If you want even more comfort and performance, you can combine the new multi-channel amps with a mono block QL800.1, for example, which then confidently delivers up to 800 watts RMS per ohm.

BUY THEM NOW!! the search is OVER! 🥳
Color: Blue, Size: Queen Size Set of 2, Color: Blue, Size: Queen Size Set of 2
pillow whore here 🤭 and I very rarely find anything worth writing a 5 star review for but let me just save you the time of searching anymore for the PERFECT pillow!!! BUY THEM! 😍 I promise you will NOT be disappointed!! I have spend thousands on pillows over the years, trying to find the perfect pillows... As someone who suffers from debilitating chronic pain and who has had multiple neck and back surgeries I'm very particular about pillows & have such a hard time finding one's that are comfortable, not too hard, not too soft but also offer great support. I FINALLY found them 🥹 and my hubby is Italian and stays hot but gets even hotter when he sleeps so finding an authentic cooling pillow has seemed impossible UNTIL now!! Just wow!! Now Im adding more to my cart while they are still 70% off 🥳🤩

Loved the pillows
Color: Blue, Size: Queen Size Set of 2
I don’t get paid for reviews so if you want a real one here ya go …. These pillows are great in my opinion. They came vacuum sealed and popped right up “ big and fluffy” immediately, as in big enough I wasn’t sure they would fit in my pillow cases. I used them last night and even though they are full, big and fluffy they still smashed down to a proper size when I laid my head down. First night in a long time I did wake up with a headache. I was extremely happy with these pillows. Now cooling ….I didn’t really find a difference from a reg pillow but, that again just could be me. Hope this helps

Heavenly Sleep Upgrade – DIORIS Pillows Are a Dream Come True!
I’ve finally found the perfect pillows! The DIORIS Queen Pillows Set of 2 has completely transformed my sleep experience. From the moment I laid my head down, I felt like I was at a luxury hotel — but right in my own bedroom! These pillows strike the ideal balance between softness and support. The premium down alternative filling cradles the head and neck gently, yet offers just the right amount of firmness. Whether I sleep on my side, back, or stomach, these pillows adapt perfectly and keep me comfortable all night long. The slow-rebound, breathable fiberfill is a game changer. It stays cool, supports proper posture, and even helps reduce neck pain — something I’ve struggled with for years. I wake up feeling refreshed and ache-free, which is priceless.
