A really good subwoofer system always needs an additional powerful amplifier. If the installation of an external amplifier is too complex or you don't have the space, you can use active models that already have pre-installed amplifiers. But beware, often for cost reasons, analog power amplifiers that are rather weak or outdated in terms of performance are often installed. Sometimes even the simplest 12 volt bridge chips can be found inside that do no more than simple car radios. ESX takes a different approach here and integrates state-of-the-art Class D amplifier modules that can mobilize up to 400 watts/RMS output power. Equipped in this way, the very compact QUANTUM QXB active subwoofer systems deliver extremely high performance and bass levels.

 

Therefore ESX uses high-quality and award-winning POWER4 active modules, which are also particularly efficient with up to 84% efficiency. Thanks to the latest Class D circuit and EPS PRO, these modules are even prepared for connection to very modern vehicles. The included cable remote control can be used to adjust the bass from the driver's seat.

ESX has also included 4 mounting feet in the active versions of the QUANTUM QXB subwoofer systems, which can be screwed onto the front if required. This means that both models can be converted into "down-firing subs" with little effort. These boxes, which radiate downwards with the woofer, are particularly suitable, for example, for installation in double boot floors.

Love it!
Color: Red Buffalo Plaid, Size: Full/Queen
Instantly became my favorite comforter for winter months. Colors are vibrant and beautiful; soft and warm; appears to be durable. I would get another of it came in others colors. Paired with the Amazon Basics red buffalo plaid sheet set. Matches my pajamas and my dogs’ bandannas perfectly!

Warm, cozy, soft, 💜 love
I don't leave reviews very often (yes that is cliche) I just don't have time. I have been debating for a few months one what I actually wanted to do with my bedroom. Spring is coming and the dark is getting to me and wanted to still get an elegant feel. I have some light baby blue around in my other comforter but I needed lighter brighter. I saw this and how SOFT is looked and I LOVE soft and cozy, who doesn't? I am so glad I took the chance. With that I also ordered the pillow....what I thought were pillows but didn't read very clearly they were just the covers so I ordered pillows then the picture I knew would still be elegant but be able to tie all the peices in and OFF the internet. Sometimes colors are not the same online as in person since monitors are always different shades of a color. Now on to this comforter. I didn't realize it came with the pillow covers. 💜 the set comes vacuum sealed but it is heavy when vacuumed. I undid the packaging a day later when I had time to wash. The cover flew out and I was perplexed, it's a pillow cover!!!! Awesome!!!! Ohhh there's 2, woohoo! Omg it's so soft. Oh I'm in heaven. Mmmmm hugging the pillow cover, I knew this was my kinda softness bed comforter. It is not LIGHT weight like say a throw blanket but it is light vs heavy bulky goose downs even though they say those are light. And when you wash it, its def not heavy if u spin the water out at super high setting on ur washer. I was able to carry it to the dryer fairly easy 20 ft away. This is by far the BEST comforter I bought in my life. I am a hoarder when it comes to comforters. Thinking if I'm ever homeless I'll have lots of somethings to keep me warm. For the price and the quality, (the batting inside doesn't shift when washing) this will be another purchase in the future in another color so I can start a soft collection. I usually give my comforters that I dont use ( the oldest but still perfect condition) to a friend or homeless. Great product!!!!

Soft warmth for cold nights
Color: Charcoal, Size: King
This bedding set with faux mink fleece and sherpa backing is perfect for cold weather or low-heated rooms. It’s ultra-soft on both sides, and the down-alternative fill keeps warmth in without feeling heavy. The reversible design lets you switch up the look, and the stitching holds up well. Even after several washes, it keeps its texture and shape. No clumping or loss of loft. A practical choice for anyone who wants comfort, warmth, and simple style.

Warm, soft, cozy… not very fluffy though
Color: Tide Pool Blue, Size: Full/Queen
I LOVE this comforter!! The color is beautiful, it’s super soft, it’s nice and warm, and it has a nice weight to it. I will say it isn’t as fluffy as it seems in the pictures, there doesn’t seem to be any filling between the 2 layers, and if there is, it’s minimal. It’s more like the thickness of a similar double sided throw blanket. It also has the tendency to grab any small debris which clings to it, but this is to be expected with this type of fabric. I would not recommend this comforter for pet owners as it will definitely be covered in hair and whatever else your furbabies may track in! Despite the lack of fluffiness and it constantly holding on to any loose thread or other random debris, I am still very happy with my purchase. Very good comforter for the price and it looks beautiful on the bed!!
