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.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

The most perfect pillow!!!
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I have spent so much money over the years, 14 years to be exact in trying to find the perfect pillow. I have finally achieved that by buying this amazing memory foam pillow. What I've been searching for is this exact pillow. It's firm, but yet soft and so comfortable. It forms to your head and shoulders. I don't constantly wake up in the middle of the night to fluff my pillow, this pillow stays fluffed throughout the night. The price is a steal and bcuz it's been so hard to find this perfect pillow that I first bought 1 set to try it out and ordered another set right away. I have total of 4 of this amazing pillow. Thank God literally, I am finally done buying pillows. Thank you Amazon for the best purchase ever!!!!

Feels amazing
Color: White, Size: Standard (1 Pack)
This pillow has completely transformed my sleep! From the very first night, I noticed how comfortable and supportive it feels. The filling is just right — not too firm, not too soft — and it cradles my head and neck perfectly, helping me wake up without stiffness or discomfort. I’ve tried several pillows over the years, but this one stands out for both comfort and quality. It stays fluffy throughout the night and doesn’t flatten like some others do. The cover is soft and breathable, which keeps things cool and comfortable even on warmer nights. Overall, this pillow offers excellent comfort and support at a great price. Whether you’re a side, back, or stomach sleeper, I’d highly recommend giving this one a try — it’s helped improve my sleep and I’m very happy with it!

Affordable, but lower quality than I expected
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I had an adjustable pillow that came with white, soft, shredded foam with fibers. It was super comfortable. When it came time to replace that one, I specifically chose this OAISZ pillow based on the listing photos that show this has white, soft, shredded foam with fibers. Unfortunately, what I received was low quality blue foam chunks with no fibers. The foam has thick, stiff edges that I can feel. While I was filling the pillow with the foam chunks, I noticed the outer pillowcase had stitching unraveling. The pillowcase feels cool at first, but then it heats up. Overall, these are affordable pillows for a set of two. However, they are low quality. The pillow is comfortable enough to sleep on, but I’m disappointed that the filling is not what is shown in the listing photo. UPDATE: The seller reached out to me after I left the above review and proactively offered a refund which I appreciate. I have revised from 3 stars to 4 stars as a result. The product was not for me, but the customer service was outstanding.
