Pioneer TS-A709 2.75" A-Series 2-Way Coaxial Car Speakers 450W Max (Pair)

The Pioneer TS-A709 is a 2-way coaxial car speaker pair designed for enthusiasts who want open, smooth highs from a compact 2-3/4" woofer and strong transient handling. With 450 Watts max and 100 Watts RMS nominal (with an inline filter), it offers headroom for a range of amplifier setups while maintaining detail.

• 450 Watts Max Power: Provides peak handling for transient musical moments when driven by a capable amplifier, helping bass and dynamics stay clean at higher listening levels.
• 100 Watts Nominal Power (RMS) with inline filter: Indicates continuous power handling; paired with the inline filter, it supports controlled frequency response and dynamic listening without overdriving the woofer.
• 2.75" carbon and mica reinforced IMPP cone: A stiff, lightweight woofer material that minimizes distortion and maintains stable midbass in the confined cabin space.
• 16mm polyetherimide (PEI) hard dome tweeter: Enables extended high-frequency response for crisp detail and air in the upper range of the audible spectrum.
• Frequency range: 101 Hz to 34 kHz (without filter); 850 Hz to 34 kHz (with filter). Without a crossover, it covers a broad range; with the inline crossover, the woofer-tweeter blend becomes more precise for smoother high-end integration.
• Impedance: 4 ohms. A common car-audio load that works well with a variety of amplifiers while balancing efficiency and volume potential.
• Sensitivity: 82 dB (1W/1M). Reflects how loudly the speaker will play per watt of input, guiding how much amplifier power you’ll need to reach higher listening levels.
• System Type: Coaxial 2-way with a dome tweeter, designed for straightforward installation and consistent tonal balance with other A Series components.
• Crossover network: Inline packaged crossover with an 850 Hz crossover point when used, helping to separate bass from treble for clearer imaging.
• Physical fit: Cut-out 2-1/2" and mounting depth 1-1/4" (31.8 mm); woofer dimensions 6.5". This makes the TS-A709 suitable for shallow door cavities while delivering solid bass presence.
• OPEN & SMOOTH design: Shared across A Series for a cohesive tonality when paired with other A Series speakers, reducing tonal gaps in a multi-speaker setup.

The TS-A709 is well suited for compact door installations where space is limited but musical detail matters. Its 4-ohm load pairs well with a range of amplifiers, and the inline crossover helps achieve smoother high-end integration in typical vehicle interiors, producing a natural, coherent front-stage sound when used as part of an A Series system.
