Q: Can I wire multiple JBL Professional CSS8008 speakers in parallel?
A: Yes, you can wire multiple JBL Professional CSS8008 speakers in parallel. However, your amplifier has to be capable of 25v or 70v output, and you just wire them from one to the other. This is not a 4-Ohm/8-Ohm setup with these speakers.

Q: Do I need a baffle to install the JBL Professional CSS8008 in a ceiling?
A: Whether or not you need a baffle to install the JBL Professional CSS8008 in a ceiling depends on the material it is hanging from. Whenever this type of speaker is installed on a drop ceiling, you should always install an appropriate metal support frame to prevent the weight of the speaker from causing the ceiling tile to collapse, potentially injuring occupants. If ceiling tiles are exposed to a small water leak they will collapse quickly. If you're going to mount it in drywall, make sure to use toggle bolts. Any ceiling-mounted speaker should have a back-up cable type of support system in the event that the structure it is mounted to collapses.

Q: Does the JBL Professional CSS8008 have volume control?
A: No, the JBL Professional CSS8008 does not have volume control on the speaker.

Q: What wire should I use to connect the JBL Professional CSS8008 speakers to a phone paging system plus music player?
A: Any gauge over 16 is fine, but you should make sure that you use speaker cable that has a minimum rating of 100 volts. If you want to do it professionally, you can buy shielded cable and ground the shielding wire to the amplifier and ceiling grid. This prevents humming and interference within the cable.

Q: Can I connect the JBL Professional CSS8008 as two bare wires to the amplifier?
A: Yes, you can connect the JBL Professional CSS8008 as two bare wires to the amplifier.

Q: What is the recommended use for the JBL Professional CSS8008?
A: The JBL Professional CSS8008 is recommended for music applications in commercial settings such as offices, conference rooms, and small church auditoriums.

Q: Is there a ceiling tile speaker with volume control?
A: Yes, there are ceiling tile speakers with volume control available in the market. You can also add a control called an L-Pad to any ceiling speaker lacking one. The L-Pad is basically a potentiometer that can be purchased online for $5.00 to $15.00 each.

Q: What are some optional accessories for the JBL Professional CSS8008?
A: The optional accessories for the JBL Professional CSS8008 include tile rails and matching back cans made of zinc-plated steel with a powder-coated finish. These accessories make it easy to mount any of the CSS 800 Series speakers.
