What is the total power output of the SubZero C10A?

The speaker delivers a continuous output of 250W RMS and can reach a maximum peak of 500W. This provides enough headroom for small to medium-sized indoor gatherings.

Can I connect a second speaker to the C10A?

Yes, the unit features a 2-pole extension speaker output. This allows you to connect a passive speaker, such as the SubZero C10M, to create a stereo PA system powered by the C10A's internal amp.

What size is the main woofer?

The C10A is equipped with a 10-inch long-throw woofer. This size is chosen to balance portability with the ability to project full-range sound over distance.

Does the speaker have built-in EQ?

Yes, the rear panel includes four digital EQ presets. These allow users to quickly sculpt the output sound to suit different environments or audio types.

What type of tweeter does it use?

The high frequencies are handled by a piezo tweeter. This component is designed to provide precision and clarity in the upper frequency range.

Is this a passive or active speaker?

The SubZero C10A is an active speaker, meaning it has a built-in amplifier and requires a power source to operate. It does not need an external power amplifier.

What inputs are available on the rear panel?

The integrated mixer features flexible mic and line inputs. These allow for the direct connection of microphones or playback devices like mixers and instruments.

Can I send the audio signal to another device?

Yes, the speaker includes a Line Out channel. This can be used to daisy-chain the signal to other active speakers or recording equipment.

What is the cabinet material?

The enclosure is finished in a durable carpet material. This provides a rugged exterior that helps protect the speaker during transport and handling.

How much does the SubZero C10A typically cost?

The typical retail price for this model is approximately £140.00. This places it in the affordable, entry-level category for active PA equipment.

Is the C10A suitable for use as a stage monitor?

While primarily a front-of-house PA speaker, its compact 10-inch design makes it suitable for monitoring roles. For a dedicated passive equivalent, the C10M is often used alongside it.

How does the C10A compare to the SubZero P15X?

The C10A is a smaller, more portable 10-inch unit with a carpet finish. The P15X is a larger 15-inch speaker that typically offers more low-end response and different DSP features.

Overview

The SubZero C10A is a compact sound reinforcement solution positioned within the budget-friendly segment of the PA market. It is housed in a durable carpet-covered cabinet, designed to withstand the rigours of transport and frequent setup. The unit combines a power amplifier, transducer components, and a mixing interface into a single enclosure, eliminating the need for external power amps in basic setups.

Features and Engineering

The internal architecture of the C10A is centred around a 250W RMS amplifier module capable of reaching 500W peak output. This drives a two-way driver system consisting of a 10-inch long-throw woofer for low-to-mid frequencies and a piezo tweeter for high-frequency reproduction.

A notable inclusion is the rear-panel mixer, which provides mic and line-level inputs. Users can adjust gain levels independently and apply one of four digital EQ presets to tailor the frequency response to the specific venue or application. Additionally, the unit features a 2-pole extension speaker output, allowing it to power a passive speaker (such as the C10M) to create a cost-effective stereo system.

Sound Character

The C10A is engineered for a rich, full-range sound profile. The long-throw design of the 10-inch woofer is intended to maintain clarity and projection over longer distances compared to standard short-throw drivers. The use of a piezo tweeter ensures precision in high-frequency detail, making it suitable for both vocal reinforcement and music playback.

Target Audience

Given its compact size and weight, the C10A is primarily aimed at mobile performers, public speakers, and small musical ensembles. It serves as an entry-level solution for those needing a portable PA for small venues, rehearsals, or presentations. The ability to expand via a passive slave speaker also makes it a viable option for small-scale event organisers seeking a scalable audio system.

Market Comparison

Within the wider PA market, the C10A occupies a similar space to the SubZero P15X, though with a smaller 10-inch footprint compared to 15-inch alternatives like the dB Technologies B-Hype 15 or RCF ART 735-A. While it lacks the high-end professional specifications of the Turbosound iQ10 or RCF NX series monitors, it offers a functional utility-to-cost ratio for budget-conscious users.
