Pioneer TS-G1731i Car Speaker

The Pioneer TS-G1731i is a 17 cm dual-cone car speaker designed for in-car audio systems. Its 38.5 mm mounting depth helps when planning installation in a compact cavity. The 4 Ω impedance must be matched to the car stereo or amplifier channel. Its 40 W rated input power is the key figure when selecting suitable amplification.
The Pioneer TS-G1731i car speaker is a 17 cm dual-cone model designed for in-car audio systems. It has a rated input power of 40 W and an impedance of 4 Ω. Its 38.5 mm mounting depth must be compared with the available space and any vehicle components located behind the mounting opening.
Purpose and selection
This model is suitable for replacing a factory-fitted car speaker or assembling a new audio system. Three dimensions are particularly important before installation: the 17 cm external size, the required 128 mm mounting hole, and the space needed to accommodate the 38.5 mm mounting depth.
The dual-cone design allows a single speaker to reproduce a broad range of frequencies. No separate tweeter is specified. This model should therefore not be confused with a coaxial multi-way speaker containing separate low-frequency and high-frequency elements.
Construction and materials
The woofer cone is made from IMPP composite. This material forms the main moving part of the speaker, transferring sound-producing vibrations into the vehicle interior.
The voice coil is made from copper, while its former is made from polyimide. The magnetic system uses a ferrite magnet.
Planning the installation
The stated 17 cm size alone is not enough to determine whether this speaker will fit a particular vehicle. Installation requires a mounting hole with a diameter of 128 mm. There must also be sufficient clearance behind the speaker for its full mounting depth.
Before installation, measure the distance to the window mechanism, interior trim, and any other parts positioned behind the opening. The speaker rim should rest securely against the mounting surface. A firm mounting base helps reduce unwanted vibrations from surrounding trim panels.
If the vehicle’s original opening or fixing points differ from those required by the speaker, a vehicle-specific installation solution may be needed. The inclusion of any such installation accessories is not specified.
Electrical compatibility
The speaker’s 4 Ω impedance must be compatible with the load supported by the car stereo or amplifier. An unsuitable load can cause the amplifier to operate incorrectly. When checking compatibility, refer to the permitted impedance for each individual amplifier channel.
If several speakers are connected to one channel, the total load will depend on how they are wired. Parallel and series connections alter the resulting load in different ways. The safest arrangement is therefore to connect this model to its own channel that supports the required impedance.
When installing speakers on the left and right sides of the vehicle, the polarity must be consistent on both sides. Matching the connections helps the cones move in phase and supports more stable low-frequency reproduction.
Power handling and frequency reproduction
When selecting an amplifier, the most important power figure is the 40 W rated input power. This value provides a more useful indication of continuous operation than the maximum figure. The 230 W maximum input power must not be treated as the speaker’s continuous operating power.
The specified frequency range of 30-23,000 Hz covers low and high audio frequencies. The final result will also depend on the mounting position, the door cavity, and the settings used throughout the audio system.
The 89 dB sensitivity helps indicate the sound level the speaker can reproduce from the same amplifier signal. Its lowest resonant frequency is 77 Hz. This figure can be useful when integrating the speaker with other components in the vehicle’s audio system.

FAQ
What is this speaker designed for?
It is designed for use in a car audio system. The model can be chosen to replace an existing speaker or to install a new system in a suitably sized location.
How can I determine whether it will fit my car?
Compare the opening, available mounting depth, and fixing position in the vehicle with the dimensions shown in the specification table. The nominal speaker size alone is not sufficient to confirm compatibility.
What should I consider when choosing an amplifier?
The amplifier channel must support the speaker’s load. Match the amplifier using the rated power figure rather than the higher maximum value.
Is this a coaxial speaker?
No. It uses a dual-cone design. This is not the same as a coaxial model with separate low-frequency and high-frequency elements.
Can it be used in a home stereo or cinema system?
This model is intended for a car audio system. Home systems use speakers with suitable enclosures and impedance characteristics matched to the particular system.
How should the left and right speakers be connected?
Maintain the same positive and negative terminal polarity on both sides. Switch off the audio system before making the connections, and check the wire markings carefully.
Should the maximum power figure be used to select an amplifier?
No. When selecting an amplifier, check that its channel supports a 4 Ω load and the intended speaker wiring arrangement.
