The ICE800ST is a high-end commercial speaker that will come through with excellent sound quality even in crowded, noisy environments. Not only does this speaker offer high power handling, the 6.5" polypropylene woofer and pivoting tweeter configuration is similar to home theater speakers where sound clarity is fine tuned. If you want "beyond good" sound quality and a speaker that rises above the clamor and noise, the ICE800ST will be an excellent choice.

This ceiling speaker with backcan is perfect for a commercial application. It has built in 70V transformer but also has 8 ohm setting so you can use for your regular 8 ohm application. It is very easy to remove the grill to adjust the 70V setting. The one piece grill covers the complete speaker for better custom looks. Sophisticated crossover delivers better bass, clarity and clean highs.

How Does this Speaker Mount in the Ceiling?
Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. The answer is no and here’s why. All our in-ceiling speakers feature a dog leg (L-shaped) mounting system that is part of the frame. Before you install the speakers, remove the grille and you’ll see several the mounting screws near the front frame. These screws need to be loosened to activate the dog leg clamps. Use a screwdriver to loosen (turn to the left) these screws and the clamp will come loose. When the speaker is in position in the ceiling, tighten (turn to the right) the screw and the speaker will be secured to the ceiling.

What Type of Speaker Wire and What Gauge?
Wiring is not included with in-ceiling speakers so you will have to purchase some. We recommend our OSD Audio CL3/FT4 cable that is UL (fire) rated for in-wall and outdoor speaker installs. This type of cable includes a heavy-duty outer jacket approved for in-wall/in-ceiling installation. The high-quality plastic jacket is also very flexible so it's easy to run the wires inside the wall. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

What Is Butyl Rubber Surround?
With almost double the shelf life of foam, butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. The Surround is just one of the integral parts of the speaker's motor structure. Butyl Rubber gives the speaker more excursion capability featuring a deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to the foam at 12 to 15 years.

For a retrofit installation, no construction bracket is needed

Rick • 12/17/2019, 2:17:43 PM Will I need a bracket to install in a drop tile ceiling
Customer Service • 12/17/2019, 2:17:43 PM
Hi Rick: The speaker will mount in a drop down ceiling as is but we do recommend cutting the hole and mounting the speaker in the tile after you have removed it from the ceiling. Another tip is to have you add small wooden strips (1 x 3 x 1/4") underneath each Dog Ear Mounting clamp. This increases the striking surface for the clamp and provides a wider more stable base to clamp down on the tile. With the Tile removed from the ceiling it is much easier to secure the speaker with these wooden strips while mounting the speaker to the tile. TL/3755
John InView • 12/17/2019, 2:17:43 PM I purchased a PC640 to test out. I am impressed with its sound, however I feel that I need the lower frequencies. So, now I am considering the ICE800ST,.... however I really need a pendant type design. So, are there points on the backcan that can be drilled to add eyebolts with nuts to use as suspended speakers? Or, do you have a kit to do that?
Customer Service • 12/17/2019, 2:17:43 PM
Hi John: There is a safety ring which connects to a safety wire but this speaker is definitely meant for in-ceiling where the mounting brackets and back can are hidden in the ceiling. And yes with a Frequency response of 45 Hz it definitely will deliver more bass compared to the PC at 120. Do you have the space to add sub woofers to go along with the pendant speakers. Checkout our SL800 on-wall sub with an 8.0 and 10 inch woofer. We have a custom installer who runs four of these subs around the Boiling Crab Restaurants out in Southern California. He connects as series parallel so the four show a 8 ohm load to the Dedicated Sub woofer amplifier but has four times the power handling, much lower distortion and the sensitivity is closer to 100 Hz. They connect with a SAM300 sub amp (found on our OSD website). On the good side the PC have much greater dispersion pattern and are complimented by the subs. TL/4878
John AVCam • 12/17/2019, 2:17:43 PM Is there an advantage in this speaker having its highest tap value at 10 watts when most others have higher tap values of 20 or 30 watt?
Customer Service • 12/17/2019, 2:17:43 PM
Hi John: The combination of 8" and transformer with 10 Watts as its highest setting allowed us to be very competitive with this speaker. It does have an 8 ohm setting which it will do 120 Watts and go down to 45Hz at 89 dB sensitivity. Plus featuring tuned back can with safety ring, win, win, win! TL/4907
Ar • 12/17/2019, 2:17:43 PM HiI'm planning to buy 12 of this speakers and use the amp PA150, How the sound will be at 5w @ 70v setting? Using the wire 16 G.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Ar:The PA150, rated at 120 watts, the rule of thumb is to calculate your setup using 80% of the rated power. So you would have 96 watts available. You could connect up to 19 speakers with the taps set to 5W. Or there may be higher traffic areas where you can set up to 6 of the ICE800ST to 10W and the other six speakers at 5W. All your speakers do not have to have the same Tap setting. 16 gauge will work correctly for this application.TL/5653
Wayne • 08/23/2021, 7:08:36 AM Are these OK for outdoor? Will be under a roof under an open deck, but in the salt air. ALSO, when will you have stock?????
Customer Service • 08/24/2021, 12:24:33 PM
Hi Wayne: Both the ICE800ST and ICE620ST are scheduled for the week of August 23rd. Unfortunately, the grills are not Aluminum, so not recommended for outdoor, especially if Salt is in the air. Our ICE WRS speakers feature rust-proof aluminum grills but do not feature an internal 70V tap. The best choice for outdoor 70 volts would be the AP525 or AP650 Patio Speakers featuring Aluminum grills. TimL/8-24
