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.

Say goodbye to neck pain
Color: White, Size: Queen
This is a very good product but it takes some time to adjust removable stuffing to accommodate individual sleeping patterns.

Soft and comfortable cooling pillowcase that gets the job done!
Color: White, Size: Queen, Color: White, Size: Queen
I got this quilted bamboo pillow protector (queen size) because I wanted a cleaner, cooler layer between my pillow and pillowcase since I’m always hot. This has been a great solution for that. The fabric feels soft and smooth, and it doesn’t make that crinkly noise some cooling pillowcases do. I’m a warm sleeper and the “cooling” aspect feels more like breathable than icy-cold, but it definitely sleeps more comfortably than the thick polyester protectors I’ve used in the past. The light quilting adds a little cushion without making my pillow feel bulky or changing the loft much. I like the fact that if you use a memory foam fill pillow you can add or remove some of the filling to make the pillow as firm or mushy as you want. This is especially helpful for people that are side sleepers vs people that need more neck support. The zipper is a big plus. Just be careful when zipping it open and closed as these are usually the first point of failure for pillowcases in my experience. It closes fully and keeps the protector snug so it doesn’t shift around inside the pillowcase, and it gives me peace of mind for sweat / oils and everyday wear. I’ve washed it and it came out fine with no weird shrinking, and the stitching still looks clean. For the price, it feels like good value if you’re trying to extend the life of a nicer pillow while keeping the sleep surface soft and breathable. It’s one of those small upgrades you don’t think about much once it’s on, which is kind of the point. It just works and helps me sleep more comfortably.

Soft and cooling
Color: White, Size: King, Color: White, Size: King
This pillow cover is great! Well made. Not too thin. Fits my queen pillow like a glove. Came out of the washing machine still looking brand new, with no zipper issues, which can happen with lower quality covers. Zero complaints.

Soft, Cooling Pillowcase That Smooths Out Chunky Filling
Color: White, Size: King, Color: White, Size: King
I accidentally ordered the king size instead of queen, but it still fits my shredded latex foam pillow fairly well and feels comfortable. The pillow has small but chunky latex shreds, and the added foam layer in this pillowcase not only smooths out those chunks but also adds a bit of extra thick comfort, making the pillow feel more uniform. ​ It seems to help with temperature regulation—if anything, it’s subtly cooler or at least not any warmer than my previous pillowcase. I’ve washed it twice so far, and it shows no wear and seems well built, so it should hold up over time and seems totally washable. Overall, it’s a very functional item, and compared with similar products, the value seems reasonable; I’m happy with the purchase and just wish I had ordered the right size. ​

Good quality cover
Color: White, Size: Queen, Color: White, Size: Queen
First, this pillow cover arrived in a plastic bag (see 4th photo), not a box as the photos online show. Although that does not matter to me, it may matter to other people such as those who intend to give this as a gift. One of the photos I included shows the fabric makeup which is mostly polyester and memory foam with the outer cover having “40% Bamboo Rayon.” It seems like an overstatement to me to market this product as a “quilted bamboo pillow cover” where there’s very little, if any, actual bamboo in it. If you have read up on what “bamboo rayon” actually is, you’ll understand. The material make up aside, the cover is soft and puffier than a cotton pillowcase. Bamboo rayon does have qualities that allow airflow for a cooling type of effect. It washes very nicely. As for the size of the pillar cover, I have tried several pillows inside this case, and the case is at least 2 inches longer than every standard pillow I own (See second photo). Pillowcases with a zipper generally are more fitted in every dimension. This pillow cover fits in all dimensions, except for it is longer than necessary. Not a horrible thing, but worth mentioning. The sewing of this product is good. It has a standard plastic zipper. There’s piping around the entire seam area for touch of class. The gray piping on mine matches the quilting. This is not quilting of the standard sense where threads go through to the other side. It is more of a faux quilting, which you can that on the inside in the photo with the tag. Overall, it seems to be a good product especially for people who sweat when they sleep.
