The off-white Bogen Communications HFCS1 is a 6.5" 75W passive ceiling speaker designed to deliver full-range frequency reproduction for clear, intelligible foreground sound and speech reinforcement in offices, retail environments, transportation facilities, and more. It features a computer-matched venting system that aids the speaker in achieving a full bass output and a large back can for extended bass response.

The HFCS1 utilizes a coaxial speaker design with a 6.5" polypropylene cone woofer and a 0.75" polycarbonate dome tweeter, yielding a frequency response of 65 Hz to 19 kHz (-10 dB) and high power handling capability. A front-mounted transformer tap selector provides easy access to a variety of 70V/100V power taps and a 16-ohm transformer bypass setting.

Wiring and installation is simplified thanks to the snap-lock input connector and integral swing-out clamps. The speaker is supplied with an input terminal cover with knockouts for additional protection of the connections.

Q: 4. Does this lens create a circular fisheye image on a full-frame camera such as the Nikon D610?

A: The image would be nearly circular but because the lens was made for APS-C size (crop frame) sensors, the inside barrel of the lens would be visible in most photos. This Nikon 8-15mm fisheye zoom would be a better option: https://bhpho.to/3t8qi4G

Q: 5. can this fit a canon xl1 if I bought a adapter too ?

A: If you purchase the FotodioX Pro Lens Mount Adapter Canon EOS/EFs to Canon XL Mount, B&H # FOPCXLACE, then yes, the Opteka 6.5mm f/3.5 Circular Fisheye Lens for Canon EF, B&H # OPT65C, may be used on the Canon XL1 MiniDV Digital Camcorder. Do note that there is no electronic control of the lens through the adapter, so you need to use a lens that has manual focus and iris capabilities (such as the Opteka 6.5mm f/3.5 Circular Fisheye Lens you listed above). However, the adapter allows TTL (Through-The-Lens) metering, and when using a lens with the adapter, the camera body should be set to either manual exposure or aperture priority mode.

Q: 8. will this work for the cannon vixia hf r800?

A: No, the Opteka 6.5mm f/3.5 Fisheye Lens for Canon EF would not be compatible for use with the Canon VIXIA HF R800 Camcorder. The Opteka 6.5mm f/3.5 Fisheye Lens for Canon EF is designed for use with Canon cameras that use interchangeable lenses and which use the Canon EF-mount lens mount, whereas the Canon VIXIA HF R800 Camcorder is a camcorder with a built-in non-removeable lens. If you need a 43mm screw-in filter compatible for use with the Canon VIXIA HF R800 Camcorder, then I would instead recommend the Raynox HDP-2800ES High Definition 0.28x Diagonal Fisheye Conversion Lens, B&H # RAHDP2800ES, for your usage needs.
