Key Information

  • Sensitivity (1W @ 1M): 85 dB
  • Power Handling (RMS): 150 W (full range – IEC268-5 rating)
  • Nominal Impedance: 8 ohms
  • Driver Size: 20 cm
  • Sold As: Single Speaker

The Monitor Audio ICS-8 subwoofer enables system-enhancing bass from the most visually discreet of settings. Developed primarily to complement the Monitor Audio CF230 speaker system, the ICS-8 fits into ceiling and wall cavities and under floors, enhancing the CF230 driver array and providing punchy bass from 40 Hz to 120 Hz.

Exclusively available with its specially designed pre-construction to allow a precise edge to plaster and finish, the ICS-8 follows the same visual appearance as the CF230, with round and square flush fit grille options on offer. Integrators can combine an IC8-S with a CF230 system, fit grilles to match and create a stunning sounding audio system from a practically invisible, yet extensive, speaker set up.

The ICS-8’s 20 cm long throw driver uses Monitor Audio’s renowned C-CAM cone technology to help ensure excellent reliability, as well as outstanding audio performance. Angled internally in the rigid MDF enclosure to reduce the ICS-8’s overall box height, this specially designed driver operates in the small bandpass area, treating listeners to tuneful, punchy bass.

This design provides the performance of 20 cm subwoofer from but a 10 cm grille opening. The ICS-8 is used in mainly pre-construction installations, when and where access can be made, such as in a basement, and when afforded sufficient joist depth and spacing.  This set up allows the Monitor Audio subwoofer to breathe new audio life into an old environment.

In new projects, the CFB3-R and CFB3-SQ pre-construction kit makes installation a thoroughly rewarding process. Integrators simply mount the bracket, which enables the cutting of the cut-out hole, and – after the plasterboard is fitted – allows them to secure the tube to the d-ring. The ‘mud bank’ fits to the plasterboard prior to plastering, and the plastering shield allows skimming up to, and very slightly over, the entire bracket. When dry, integrators sand back the area around the aperture to reveal a beautifully precise, clean edge. The resulting fit, especially when the grille is painted to match the ceiling colour, is perfectly discreet, with no edges or shadow to catch the eye.

The Monitor Audio CF230 speaker is the perfect visual and audio match for the ICS-8 subwoofer. Combine the ICS-8 with a maximum of eight CF230s, providing the sub with a single/mono channel of amplification, and you can create a sensational sound system, which operates with aplomb out of incredibly unobtrusive openings. With regards to power, the Monitor Audio IA150-8C eight channel DSP amplifier effortlessly drives six CF230s with two spare channels to take charge of a single ICS-8, or even a pair of the new subwoofers.

The ICS-8 subwoofer further demonstrates Monitor Audio’s commitment to designing and building discreet speaker systems which deliver on all three fronts – fit, finish, and performance.

Perfect Jumbo Size with Hotel-Quality Comfort & Support
Color: White, Size: Queen(Pack of 2)
I recently purchased the Jumbo size pillows. After trying a week, I couldn’t be happier with them! The size is perfect—nice and full without feeling bulky. They provide just the right amount of medium support, keeping my head and neck comfortable whether I’m sleeping on my back or side. The 100% cotton cover feels soft and breathable, and the pillows stay cool throughout the night. I also love the gusseted design—it really helps the pillows maintain their shape and gives them that luxury hotel feel. Even after several nights of use, they haven’t gone flat. Another big plus is that they’re machine washable, which makes maintenance super easy. Overall, these Jumbo pillows are plush, supportive, and great quality for the price. Highly recommend!

Comfortable pillows 🤩
Color: White, Size: Queen(Pack of 2), Color: White, Size: Queen(Pack of 2)
I bought the Serta Hotel Collection Bed Pillows (Queen size) and I absolutely loved them. They are super soft yet provide great support; they feel very comfortable and help make for a much better, more pleasant night's sleep. Plus, the fabric is cool and of high quality. I recommend them wholeheartedly!

Amazing pillows!
Color: White, Size: Queen(Pack of 2)
These are fantastic pillows! A little background. I'm a side sleeper and toss and turn throughout the night. I've struggled with sleep issues for literally decades - insomnia, tossing and turning, waking up multiple times a night to use the bathroom, waking up way too early and not being able to get back to sleep. Every night it's a combo of those things or all of those things. I've also had some neck pain and stiffness for a couple of months. If you've ever dealt with that you know it will affect sleep which will then affect productivity and mood. It's a terrible spiraling and compounding thing to deal with, very stressful. I figured the contour pillow I had which once was actually helping was unfortunately the culprit. So I went on the hunt for another pillow. I ordered what I thought was the old Rejuvenite pillow (those were fabulous!) and got burned on a bait and switch. The pillow ended up being way too soft and gave me worse neck pain. Figuring I'd try to salvage what was a $115 pillow, I invested in a very thin pillow to put underneath. It was too high. Getting pretty frustrated, I ordered the cheaper Utopia pillows here on Amazon. Those actually were not terrible because they did take away my neck pain, but I was still tossing and turning at night and still feeling unrested in the morning. I decided I'd give it one last shot and luckily found these when they were discounted by a few bucks. They didn't have many reviews which was actually a great sign for me because it means the company lets their product speak for itself. I got these in several days and was thrilled to see upon opening the package that they were sealed and the directions do not require you to open the package and let them expand for 24 hours. You literally just take the edges and fluff 2-3 times and that's it! They are ready to go and they definitely do feel perfect after doing that. I was skeptical when I put them on my bed because they are soft and I worried they'd be too soft. I felt my head sink into the pillow a bit and then was surprised to feel at a certain point it just feels like the pillow is cradling your head with the right amount of support. I wouldn't describe it as firm, just soft but stable support. Really comfortable. But the real test was how it would perform during sleep. I'm so thrilled to report that I had an amazing night of sleep! No neck pain, no stiffness, zero tossing and turning, no insomnia, no waking up during the middle of the night, and no waking up early. I put my head down, fell asleep, and slept like a log for about 7.5 hours straight, which is literally unheard of in my world. I'm very lucky if I get 5 solid hours of sleep. I woke up and popped out of bed. My mood was great (still is later in the day) and I was not tired in the afternoon when I normally feel the fatigue kicking in. This is the first day for as long as I can remember that I do not feel that nagging tiredness behind my eyes and in my body that always seems to be a steady background actor in my life. I feel great and full of energy and I was able to tackle a bunch of tasks on my someday list. This is so promising I didn't want to wait to share. If you are on the fence and are dealing with similar issues to mine, I'd encourage you to just try these. What's also amazing is these come in a set. I'm only using one so I basically have another one to use if the first one ever fails. This is the best investment for sleep I've ever made! Update: Well, after a trial period I'm removing a star because my dreamy sleep was short lived. I started to wake up more frequently during the night with these and gave up midway through the night one night. I'm still using these for back support while I sit up or hang out in bed because they are still super comfortable that way and oddly these work well for naps. Hopefully, you have better luck than me!
