Additional Information on the PRi85Sub
The PRi85Sub in-ceiling subwoofer has a built-in passive crossover. If the
subwoofer is receiving a full range signal from the electronics set the
switch on the front of the speaker frame to the "DirX" position to use the
internal crossover. If the PRi85Sub is connected to a component that has
an electronic crossover, such as the Boston Acoustics SA1, you will want to
bypass the crossover. In this instance set the switch to the "DIR" position.
NOTE: The DIR position is provided as a way to use an amplified LFE signal from a receiver and should be lim-
ited to 30Hz to 750Hz – to ensure the product is protected. We do not recommend or warranty this product if this
frequency limitation is not used.
Notes About Commercial Applications
The plenum rated enclosure and safety agency certified design of the PRi series speakers make them an ideal
choice for commercial installations. In such installations you may need to connect more than three speakers to
each channel of the amplifier.
Several companies make speaker distribution devices and controls that allow you to vary the impedance the
amplifier "sees" from the control/speaker combination. These devices make it possible to install an elaborate
multi-speaker system while keeping the impedance load on the amplifier in a range it can handle and provides
volume controls to balance the output of the speaker to suit the installation.
Removing the Grilles
Should you need to remove the grilles for any reason use a paper clip bent into a small hook or a grille pick.
Slip the hook through one of the holes and pull the grille straight out.
You may need to pull one edge part of the way out them move to the
other edge and gradually work the grille out of the frame.
Painting the PRi Speakers
You can paint the exposed part of the frames and the grilles of your
speakers to match your room. A paint shield is provided to protect the
speakers.
Most paints, especially water based paints, don't adhere very well to plastic surfaces or surfaces already covered
with glossy paint. So, you will need to apply a primer coat. Use a primer recommended for plastic surfaces. Be
sure it will produce a surface that the paint you are using will bond to. NOTE: Depending on the type of paint
that will be used for the final coat you may or may not need to apply primer to the grille.
Remove the grille as described in the preceding section. Put the paint shield over the front of the speaker. Apply
masking tape to all other part that should be protected. Be sure to cover the mounting clamps and the terminal
cover. Be sure the surfaces to be painted are clean and free of dust, lint, etc.
Apply two or more light coats of primer. Let the primer dry thoroughly between coats. You'll get better results
and reduce the chance of drips or runs using several light coatings. Lighter coats also reduce the chance the
holes in the grilles will become plugged with paint. Let the paint dry completely. Remove the paint shield and
re-insert the grille.
