    The ICE620ST 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 ICE620ST 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.

    edward kim • 12/17/2019, 2:17:43 PM hi i bought this speaker back in 2009 i bought bunch of them and since day one one of em wasnt working but then i was thinkinhg that whoever person install didnt install property and today i hired one guy to look up he told me the speaker was the problem.i wonder is that a possible i can exchange.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Edward: The Speaker should still be under warranty so you can send it back in to be evaluated. We may replace the driver or just exchange the speaker completely. Either way you will be ahead of the game. Contact our customer service for a return number. TL
    Mark • 12/17/2019, 2:17:43 PM I am looking for a background music system for a quick service restaurant. Looking at the PA-90 amplifier, ICE620ST in-ceiling speakers and a set of AP640T's for the patio area. Will all of these work together? Planning on putting 7 speakers in the dining area for customers and 1 in the prep area for employees. Anything else I would need?
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Mark, This setup will work fine. The only thing else you need is the speaker wire to connect all your speakers. You can daisy chain all the speakers together. We recommend setting the taps on the ICE620ST to 5W and the pair two AP640T to 8W. Hope this helps! TL/MA 1447
    Sunday • 12/17/2019, 2:17:43 PM Can I use a harman kardon AVR to power 20 pcs of these speakers?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Sunday, Are you powering these speakers only or using the AVR for both surround sound system and the 10 pair for whole house as well? If you are planning to power the speakers in addition to your surround sound system, it is recommend you add an external amplifier like our OSD AMP200 and a speaker selector box like our TSM12 and let the box handle to impedance matching protection for your whole house (10 pair). Which Harmon Kardon AVR are you using? TL/MA - 1513
    Sunday • 12/17/2019, 2:17:43 PM Can I use a harman kardon AVR to power 20 pcs of these speakers?
    Customer Service • 12/17/2019, 2:17:43 PM
    Yes for both surround sound and the 20 speakers. The particular kind of Harman Avr my client wants to bring in for the installation is not known yet. But i think your recommendation is great.
    Dan • 12/17/2019, 2:17:43 PM The description says "It is very easy to remove the grill to adjust the 70v setting" yet the picture shows the tap settings on the back of the speaker. Which is correct? Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Dan: The tap settings are adjusted on the back of the speaker. The grill needs to be removed so you can access the four mounting screws for the dog ear clamps. The Transformer Settings: 10W/5W/2.5W/1.2W & 8 ohms. TL/4590
