Metal Back Can for 8-inch Ceiling Speaker with Brackets (pair)
Adding back cans to your in-ceiling speakers is the easiest and most cost-effective means of improving the quality and volume level of the sound, as well as improving overall installation safety.
Ordinary bookshelf or floor-standing speakers use carefully designed and crafted enclosures to shape and give body to the sound produced by the drivers. However, in a basic in-ceiling or in-wall installation, the driver projects sound without the assistance of an enclosure or, if you will, using the ceiling or wall space as the "enclosure". This space is obviously not carefully designed and matched to the speakers' capabilities.
These metal back cans are designed specifically for use with the 8-inch Carbon Fiber 2-way In-Ceiling Speaker with Magnetic Grille (13683). They are easily installed on the speaker and include a mounting bracket for use with drywall or drop ceiling installations. A safety hook allows you to attach a tether to a secure point, which will prevent the speaker from falling to the ground in the event of a ceiling surface or speaker mounting tab failure.
Best of all, you will get improved sound quality and volume, especially in the bass frequency ranges.
The cans came to me with a small amount of damping material. Feel free to add more, but I think you'd find you didn't need to.
PROS: - Great build quality
- Built-to-spec for the speakers they're intended for
- EXTREMELY strong brackets
CONS: NOTE: Ultimately these are the reasons for a '3' rating
- Although the speakers are intended to accept up-to 14 AWG cable, the cans have a jumper from from their terminal block to the speaker that uses 18 or 20 AWG cable and it's soldiered to the block! I'm going to de-soldier and replace with 14 AWG since my receiver is almost 50' away from the speakers themselves.
- This may be better suited as a "Con" for the speaker, but there is a removable sealed port on the speaker that should probably be removed when used in conjunction with these cans however, it doesn't state anywhere in the instructions (for the speakers or the cans) when or for what reason to remove this port.
= The cans are constructed of metal! Realistically, plastic or composite is a far better material to build a speaker component like this. It is very likely that IF the aforementioned port is removed, harmonics from the metal can will be audible at higher volumes.
