Automotive 1″ Tantalum Dome Tweeter

The Soundstream TWS.4 is a pair of 1″ tantalum dome tweeters designed for car audio systems that need clear high-frequency reproduction. Each unit handles 110 W RMS and 200 W peak power at 4 Ω impedance. The built-in 12 dB in-line crossover simplifies installation by filtering low frequencies before they reach the dome.

Power handling and frequency limits

With 110 W RMS the tweeters deliver clean output for most component systems, while the 200 W peak rating provides headroom for dynamic passages. The specified response of 5 kHz to 25 kHz covers the critical upper octaves, but output falls off below the crossover point so a separate midrange or woofer is required for full-range sound.

Polished aluminium housing and dual mounting

The tweeters feature a polished aluminium frame that resists corrosion and looks clean on display or behind grilles. Dual-mount hardware allows either surface or angled installation, letting you aim the 95 dB SPL output toward the listening position without extra brackets.

Questions about this item

Will the 4 ohm impedance of the TWS.4 tweeters match my older 4 ohm component system?

Yes, the 4 ohm impedance is standard for car audio and will integrate directly with existing 4 ohm crossovers or amplifiers without wiring changes.

How can I verify the built-in 12 dB crossover is functioning after I mount the tweeters?

Play a frequency sweep from 5 kHz to 25 kHz and listen for smooth output up to the 25 kHz limit; the 95 dB SPL rating means they should be clearly audible at moderate volume.

Does the box include the in-line crossovers and hardware for both surface and angle mounting?

The pair ships with built-in 12 dB in-line crossovers on each tweeter and dual-mount hardware for surface or angle installation; no separate crossover purchase is needed.
