AudioControl A35C Review: Specifications, Fitment and Comparisons
Quick summary: the buying decision
The A35C is a pair of 3.5-inch component midrange speakers, rated at 50 W RMS at 4 ohm, covering 100 Hz – 15 kHz. A dedicated midrange takes the vocal band away from the woofer and tweeter, which is what makes a 3-way system sound clearer and more focused when it is filtered and placed properly.
AudioControl A35C: what it is
The AudioControl A35C is a pair of standalone 3.5-inch Altitude Series component midrange drivers rated at 50 W RMS and 4 ohm. Their extended bandwidth (100 Hz – 15 kHz) suits both 2-way and 3-way systems, and an in-line filter gives precise frequency control.
AudioControl's Altitude speakers share precision-moulded glass-fibre cones, butyl rubber surrounds, silk dome tweeters and steel slimline baskets for easier installation, and they are designed and engineered in the USA. The range covers the A65 coaxials, the A65CS2 component set and standalone A1 tweeters and A275C / A35C midranges for building a 3-way system.
Key features
Extended bandwidth for smooth integration in 2-way and 3-way systems
Lightweight aluminium dust cap enhances sensitivity and extends frequency response
Precision-moulded glass-fibre cone and durable butyl rubber surround
In-line filter for precise frequency control
Steel slimline basket with dual mounting options and direct wiring
Specifications explained
AudioControl publishes: power handling 50 W RMS; impedance 4 ohm; DC resistance 3.6 ohm; frequency response 100 Hz – 15 kHz; sensitivity 84.6 dB (1 W / 1 m) or 87.6 dB (2.83 V / 1 m).
The two sensitivity figures are the same measurement expressed two ways: for a 4-ohm speaker, 2.83 V equals 2 W, so the 2.83 V figure reads 3 dB higher than the 1 W figure.
Fitment: overall diameter 85.6 mm (3.38 in), cut-out 75 mm (2.95 in), mounting depth 34.5 mm (1.35 in), total depth 40.5 mm (1.59 in).

Fitment: will it fit your car?
Measure the factory opening and the depth available behind it, including clearance to the window glass and its channel at full travel. The A35C needs 34.5 mm (1.35 in) of mounting depth and a 75 mm (2.95 in) cut-out. Small drivers are usually mounted in the dash, A-pillars or custom pods; a rigid, sealed mounting keeps them clean at volume.
Crossover, filtering and placement
The A35C covers 100 Hz to 15 kHz and comes with an in-line filter for frequency control, so it works as a midrange in a 3-way system or as a wide-range driver in a 2-way build.
Mount midranges high in the dash or A-pillars where possible, close to the tweeters, so the vocal range and treble arrive from the same area.
Amplification
At 50 W RMS each, they can run from a modest amplifier channel; in an active 3-way build, a DSP amplifier such as the D-6.1200 gives each driver its own channel and filter.
