What is a backcan and why is it used in ceiling speaker installations?

A backcan is a pre-installed enclosure mounted behind the speaker that seals the ceiling plenum (the air space above drop ceilings), prevents sound leakage into adjacent rooms, and improves acoustic isolation.

Why does the MTC-81BB8 have extra-large volume?

The 0.26 cubic-foot volume is larger than standard backcans, providing enhanced acoustic volume that boosts the bass response of the 8138 ceiling speaker, resulting in richer low-frequency output.

How does a backcan with larger volume improve speaker performance?

Larger enclosure volume allows the speaker's driver to move more freely at lower frequencies, extending bass response and delivering fuller, warmer sound throughout the room compared to smaller backcans.

Can backcans be installed in retrofit applications or only during new construction?

Pre-install backcans are designed for installation before drywall during new construction. For retrofit installations, consult Procure.ae about alternative acoustic solutions.

What acoustic isolation does a backcan provide to adjacent rooms?

Backcans seal the speaker opening and reduce sound transmission into the ceiling plenum, providing significant isolation that prevents sound from traveling between rooms and controlling noise in shared spaces.

How many backcans does one 4-pack provide?

The MTC-81BB8 is a 4-pack providing four pre-install in-ceiling backcans, accommodating up to four 8138 ceiling speakers with the MTC-81TB8 tile bridge.

What is the lead time for backcans from Procure.ae in the UAE and GCC?

Delivery depends on stock and your location. Contact Procure.ae with your construction schedule and location to receive a quote and estimated delivery date.

Does Procure.ae coordinate with construction teams for pre-install backcan placement?

Procure.ae can advise on installation timing and best practices when you request a quote. Coordination with your construction team ensures backcans are positioned before drywall installation.

What is the volume capacity of each backcan?

Each MTC-81BB8 backcan provides 0.26 cubic feet of acoustic volume, larger than standard configurations to enhance bass response for the 8138 ceiling speaker.

What material are these backcans made from?

The MTC-81BB8 backcans are constructed from durable material engineered for in-ceiling installation. Material specifications and acoustic properties are available from Procure.ae.

What is included in a 4-pack purchase?

The MTC-81BB8 includes four pre-install in-ceiling backcans (0.26 cubic feet each) designed for the 8138 ceiling speaker. Confirm with Procure.ae what fasteners and hardware are included.

FAQ

Does the backcan really enhance bass response?
Yes, the extra-large 0.26 cubic-foot sealed chamber extends the low-frequency response of the 8138 speaker, resulting in noticeably deeper, more controlled bass in music and speech applications compared to cavity-only mounting.

Can I use nesting to stack backcans for storage?
Yes, the nesting design allows multiple backcans to be stacked together, significantly reducing storage footprint during inventory and transportation.
