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.

Asurion "Assures" nothing!
Asurion has terrible Customer Support. All machine based. They give you no phone # for human interaction. Their online Support process is very close-ended. It is a checklist designed to frustrate purchasers whose issue lies outside only the very issue. My issue: I bought "Cuisinart TOB-40FR Custom Classic Toaster Oven Broiler, Silver (Renewed)" on May 26, 2024. It stated it had a 90 day warranty. So I bought an Asurion Protection Plan also to cover it for 3 years. The toaster started flaking off metal finish inside the oven over the cooking area. I tried to file a claim with Asurion and they told me the Manufacturers warranty was still in effect and I should contact Cuisinart. This despite the oven was sold with a Amazon Renewed verbiage stating a 90 day warranty. And they have nothing on their "Machine Checklist" to cover this eventuality. And I would assume I am not the only one who takes the "Renewed" route and backs it up with a "Protection Plan". They will frustrate you no end. I suspect, like many insurances, they seek to deny, deny, deny, in hopes the purchaser will give up.

GIFT CARD AS REPLACEMENT, NO CHOICE OF CHECK OR REPLACEMENT. GOOD COMPANY
PROS: * A decent company, responsive and fair. * Allows you to buy items from anywhere you want, and buy the warranty at Amazon. * Provides better coverage than other warranties, and covers more, including breakage! CON: They don't send you a check in order to buy wherever you want, send a replacement, or give you a choice. Instead, they send you an Amazon Gift Card. That's OK if you're a big Amazon shopper, but sometimes, you can get a better price elsewhere.
