DB Drive offers several tweeter models with different mounting designs and published specifications, but those figures do not establish which one sounds best. Choose by fit, crossover and system compatibility, then treat the manufacturer’s ratings as comparison points—not independent listening-test results.
DB Drive tweeters compared
The specifications below are published by DB Drive on its product pages, accessed October 7, 2026. Power labels differ between models, so peak, RMS, dynamic and nominal ratings should not be treated as interchangeable.
| Model | Construction and design | Published specifications | Installation and system considerations |
|---|---|---|---|
| P7TW 3M | Titanium diaphragm; shallow mount | 4 ohms; 6 kHz–22 kHz; 105 dB sensitivity; 300 W peak / 125 W RMS | Integrated 6 dB passive high-pass crossover. Check the shallow-mount depth and whether the crossover arrangement suits the rest of the system. DB Drive P7TW 3M specifications. |
| P9TW 3M | Titanium diaphragm; shallow mount | 4 ohms; 6 kHz–22 kHz; 105 dB sensitivity; 320 W peak / 130 W RMS | Uses a 6 dB-per-octave crossover. Compare its stated power handling and installation requirements with the P7TW 3M. DB Drive lists replacement diaphragm P7/9TW3MRC for both models; verify compatibility before buying. DB Drive P9TW 3M specifications. |
| P5TW 3D | Aluminum diaphragm; pro-audio model | 4 ohms; 2.0 kHz–20 kHz; 101 dB sensitivity; 300 W peak / 150 W RMS | Includes a 6 dB high-pass filter. Its published frequency range and sensitivity differ from the shallow-mount models. DB Drive P5TW 3D specifications. |
| P5TW 4D | Aluminum diaphragm; pro-audio model | 4 ohms; 2.5 kHz–20 kHz; 103 dB sensitivity; 300 W peak / 175 W RMS | Includes a 6 dB high-pass filter. DB Drive lists a larger voice coil than on the P5TW 3D; confirm physical fit and crossover needs for your installation. DB Drive P5TW 4D specifications. |
| WDX5-TW | Elliptical waveguide | 4 ohms; 107 dB sensitivity; 300 W dynamic / 150 W nominal | Includes a 6 dB high-pass filter. Consider the waveguide design when assessing mounting and coverage. The product page has inconsistent naming and material descriptions, so confirm the exact current listing rather than assuming a diaphragm material. DB Drive WDX5-TW specifications. |
How to choose for your installation
Start with mounting space
Check the available opening, mounting depth and intended location before comparing output ratings. The P7TW 3M and P9TW 3M are described as shallow-mount designs; the other options have different form factors. A specification sheet cannot confirm that a tweeter will fit a particular vehicle or mounting panel.
Recommended Free Tools
Match the crossover and frequency range
Each listed model includes or specifies a 6 dB high-pass crossover or filter, but the product pages do not establish that every model will integrate correctly with every amplifier, speaker or existing crossover. Compare the stated frequency range with the system’s other drivers and crossover settings, and follow the manufacturer’s installation guidance. Do not treat the listed range as proof of how a tweeter will sound in a particular cabin.

Check impedance and amplifier compatibility
The P7TW 3M, P9TW 3M, P5TW 3D, P5TW 4D and WDX5-TW are each listed at 4 ohms. Confirm the amplifier’s supported load and the wiring configuration for the complete system; the tweeter’s impedance alone does not determine the total load when components are combined.
Read power and sensitivity figures in context
Sensitivity and power handling are manufacturer-published specifications, not independent performance rankings. DB Drive uses different power labels—peak and RMS on several models, dynamic and nominal on the WDX5-TW—so compare like labels only. The published figures do not establish real-world loudness or sound quality in a particular setup.

What the specifications say—and don’t say—about sound
DB Drive markets these products for high-frequency reproduction and describes design features intended to affect output or dispersion. For example, its P5TW 3D product page says: “A 1-inch voice coil provides responsive control and efficient power handling for clean, detailed high-frequency reproduction.” That is the manufacturer’s product description, not an independent test finding.

Replacement diaphragm compatibility
DB Drive identifies the P7/9TW3MRC replacement diaphragm for the P7TW 3M and P9TW 3M. Confirm the exact tweeter model and current part listing before ordering; the shared part name is not a reason to assume compatibility with other models. DB Drive’s P9TW 3M page lists the replacement part.
