OSD Audio ICE840WRS 8" Weather Proof Outdoor Rated Ceiling Speakers Aluminum Grill Swivel Tweeter W/ Crossover Pair

Hi Tim: The NCCB8 will be your best choice if you want to use New Construction Brackets. They are ideal for speaker placement before your ceiling is closed up. It provides a template to cut out the speaker locations. But the speaker has the mounting brackets that will allow you to mount the speaker without the New Construction Brackets. It may be a little harder to find your location after the ceiling has been closed up. TL/5342

Hi Tommy: I would be more inclined to add a pair of OS800 Omni full range speakers that have a lower frequency response (42Hz to 50Hz for the OMSUB200). It would give you more coverage with the 360 degree coverage x 2. That would work better with the ICE840 WRS. The OS800 is $14.00 less than the OMSUB200. So 2 each (or a stereo pair) would be more but they are also in stock. You could add an OVC300 outdoor volume control before the speakers and then wire the OS800 in parallel with the ICE840WRS. I hope that helps TL/4967

Hi Mike: The dog ears will easily clear your 1.5" ceiling. TL/4943

Hi Ed: They come in white but can easily be painted, both the frame and grille can be painted any color you want or need to match. TL/4903

Hi Patrick: Are you wiring your system 8 ohms or 70V? How many total speakers are you installing; approximate dimensions, what are your sources? Do you need a weatherproof design? You have a choice of of standard frame or Trim-less design. If I know a little bit more about your system I could better answer your question. tim@osdaudio TL/4898

Hi Kent: A Crossover does the same thing for an in-ceiling speaker as it does for any other speaker needing to use a tweeter and woofer (2 way) or Tweeter, Midrange and Woofer (3 way). The crossover is needed separate the High from the Low frequencies. You see there is a Frequency response listed for all speakers in their specifications. In the case of the ICE840WRS; Frequency response: 38 Hz-20 kHz. That is the frequency response for the speaker where the Woofer kicks in at 38 Hz and the Tweeter rolls of at 20 kHz. Somewhere between there is a crossover point that separates the two drivers. It might be at 3500 Hz so the woofer works between 38 Hz and 3500 Hz and the Tweeter works between 3500 and 20 kHz (20,000 Hz). If this were a first order crossover it would have a slope of 6 dB. A second order crossover is 12 dB, a third order crossover is 18 dB and a fourth order is 24 dB. So the 6 dB ist order Crossover starts the slope at 1 octave over the selected crossover point (3500Hz) or around 7000 Hz (1 octave above) for the High pass and around 1700 Hz (1 octave below) for the low pass. The two slopes intersect at 6 dB down at 3500 Hz. The higher (12, 18, 24 dB) the number the steeper the slope becomes. In simple terms in order to obtain a steeper slope you need a better crossover with more components. And the steeper slope usually means a better more accurate crossover. Take a look at the images of the ICE800 WRS and compare versus the ICE840WRS. The ICE800WRS has a first order 6 dB crossover which consists of a Resistor in line to the Tweeter which filters all the low frequencies an octave below the resonant frequency of the tweeter. So the tweeter needs to be protected and the woofer rolls off naturally with no protection. The ICE840WRS has a 12 dB crossover that intersects at the crossover point at 12 dB down as described above. There is a whole lot more and better descriptions on line, hopefully it helps answer your question. TL/4840

HI Robert: The best size is the what ever space you have available under your eves. If you can do 12 x 12 x 12 that will work just fine. These are infinite baffle design which allows them to work in a number of different enclosure sizes. My question is why in-ceiling speakers that you need to build boxes for when you have a choice of our AP650 and AP525 patio speaker which features a perfectly tuned sealed box and a unique mounting bracket that both swivels and tilts for maximum flexibility for mounting. The sealed design has our highest certified weatherproof rating. And just like in home theater you want to be able aim your tweeter at the optimum area where people will be listening. If you do decide to build an enclosure make sure you seal all the seams with weatherproof silicone including a bead of silicone along the inside of the frame so you can seal the Cutout hole. TL/4753
