Alpine SXE-2035S Coaxial Speaker System
52,00 €
Alpine SXE-2035S is a 200 mm, 3-way coaxial car speaker system designed for in-vehicle sound reproduction. Its woofer, midrange driver and tweeter are combined in one assembly, allowing them to use a single mounting location. The 45 W RMS rating and 4-ohm impedance help with selecting a suitable head unit or amplifier. Installation requires at least 75 mm of mounting depth.
Alpine SXE-2035S speaker system is a round 200 mm, 3-way coaxial car speaker system. It is designed for a location that can accommodate a speaker of this diameter and provide the required 75 mm mounting depth. Its 4-ohm impedance and 45 W RMS nominal power rating are the key figures to consider when choosing a head unit or amplifier.
Who this system is for
This model is suitable for a car audio system that uses round 200 mm speakers. Measure the installation location before buying. The nominal 200 mm size alone does not confirm that the speaker will match the mounting points in a particular vehicle.
The stated frequency response extends from 40 Hz to 20 kHz. This makes it a wide-range speaker, but a lower limit of 40 Hz does not by itself replace a separate subwoofer. The final bass performance also depends on the installation location and how well the doors or other mounting panels have been prepared.
Three-way coaxial construction
The 3-way coaxial design combines three different drivers in a single assembly. The 200 mm cone woofer reproduces low frequencies. A 28 mm dome driver handles the midrange, while a 16 mm dome driver reproduces high frequencies.
This arrangement is useful when you want broad frequency coverage from one speaker position in the vehicle. There is no need to provide separate mounting locations for individual midrange drivers or tweeters. However, enough space must still be available for the complete coaxial assembly.
The woofer uses a 25 mm voice coil. The midrange driver’s voice coil has a diameter of 13 mm. These measurements help describe the internal construction of the model accurately, but they are not vehicle installation dimensions.
Cones, surrounds and magnets
The woofer has an impregnated paper cone and a pressed-foam surround. The surround allows the cone to move as it reproduces low frequencies. A barium ferrite magnet is used for this driver.
The midrange driver’s diaphragm and surround are made from PEI. Its construction uses a neodymium magnet. The tweeter operates with a piezoelectric element.
The stated total system weight is 2.4 kg. When fitting the speaker in a door or another panel, the mounting surface must be able to support it securely. Firm fastening also helps reduce unwanted vibration from the mounting panel.
Connecting the speaker to car audio equipment
The speaker connects to the speaker output of a car head unit or an external amplifier. The output channel must be suitable for a 4-ohm load. When assessing an amplifier, compare its power output at 4 ohms with the speaker’s 45 W nominal rating.
The stated 280 W figure is the maximum power rating, not the amount of power the speaker is designed to reproduce continuously. It should not be used as the primary figure when choosing an amplifier. For everyday power matching, the 45 W RMS rating is the relevant value.
Volume, balance and tone adjustments are controlled by the connected head unit or amplifier. After installation, begin with neutral equalisation settings.
Increase the volume gradually and listen for distortion. Strong bass boost places a greater load on the speaker. If you hear distortion, reduce the volume or lower the bass adjustment.
Mounting dimensions and installation preparation
The system requires a round mounting location for a 200 mm speaker and at least 75 mm of mounting depth. Measure the existing opening before installation because a reliable cut-out diameter is not specified. The position of the mounting points must also be checked.
For installation in a vehicle door, check the clearance from the lowered window, the window mechanism and any internal reinforcements. These parts must not come into contact with the speaker magnet. The door trim must also avoid pressing against the coaxial assembly.
Connect the speakers for both channels with matching polarity. Reversed polarity on one channel can weaken bass at the listening position. After connection, listen from the driver’s seat and check that the centre of the stereo image is positioned correctly.

FAQ
Will these speakers fit my car?
The installation location must accommodate a round 200 mm speaker and provide at least 75 mm of mounting depth. Measure the opening and check the mounting points. You should also allow for the movement of the window mechanism.
What amplifier or head unit should I choose?
Use a speaker output designed for a 4-ohm load. Compare the amplifier channel’s RMS output at this impedance with the speaker’s 45 W nominal power rating.
Why should the amplifier be matched to 45 W RMS at 4 ohms?
The 45 W RMS figure describes the speaker’s nominal power rating, while an amplifier’s output depends on the connected impedance. Compare the amplifier channel’s RMS output at 4 ohms instead of relying on the 280 W maximum power figure.
Can I use this system without a subwoofer?
The frequency response begins at 40 Hz, but the final result depends on the installation. If you want stronger reproduction of the very lowest frequencies, a separate subwoofer may be required.
How should I adjust the sound after installation?
Begin with neutral tone settings and switch off any additional bass boost. Make adjustments in small steps while listening from your normal driving position.
Is this model intended for a home stereo or cinema system?
No. This is a car speaker system. Its size, mounting construction and 4-ohm impedance are intended for car audio equipment.
Can several speakers be connected to one channel?
Provide each speaker with a suitable amplifier channel. A parallel connection reduces the total impedance and may exceed the load that the head unit is designed to handle.
