Overview
Dayton Audio's TCP115-4 is a 4 inch treated paper cone midbass woofer at 4 ohms, built to slot into a car door or dash as one half of a component speaker setup rather than stand alone as a full-range driver.
The motor design leans on an aluminum voice coil former to shed heat and a 1 inch 4-layer coil aimed at low frequency response. A cosmetic low-profile flange lets it sit clean without a flush mount cutout.
- 4 inch treated paper cone woofer
- 4 ohm component midbass driver
- 1 inch 4-layer aluminum voice coil
- Low-profile mounting flange
Who it's for
Car audio builders assembling a component speaker system who need a compact midbass driver. Not the right pick for anyone wanting one driver to cover highs and lows.
Pros and cons
- Aluminum voice coil former manages heat under power
- Low-profile flange fits without a flush mount cutout
- Compact motor keeps the enclosure requirement small
- 4 ohm impedance needs an amp rated for it
- No power handling wattage or frequency response figures listed
- Midbass only, needs a tweeter for full-range coverage
Performance notes
The aluminum former helps the voice coil handle sustained power without overheating, and the extended pole piece is meant to keep the magnetic field symmetrical for lower distortion at the midbass frequencies this driver is built to cover.

Frequently asked questions
What impedance is the Dayton Audio TCP115-4?
4 ohms.
Is the TCP115-4 a full-range speaker or a midbass driver?
It is a midbass woofer meant to pair with a tweeter in a component setup, not a standalone full-range driver.
Will the TCP115-4 flush mount in a factory speaker opening?
It uses a cosmetic low-profile flange designed to look clean without a flush mount, so it can sit slightly forward of the baffle.
