If you're building or upgrading speakers, this Dayton Audio 5,000 Hz low pass crossover is a solid pick.

It's a 2nd order (12 dB per octave) Linkwitz-Riley filter that lets frequencies below 5k Hz pass through—perfect for pairing with a matching high pass filter to create a smooth, flat-response 2-way or even 3-way crossover network.

Designed for 4 ohm drivers, it handles up to 250 watts, so it can keep up with most setups.

Inside, you get high-quality air core inductors in series with the driver (which means less distortion and better sound quality), plus all components are securely mounted on a red PCB with EVA backing to prevent shorts and vibration.

The dual terminals at each connection point make wiring a breeze, especially if you're running things in parallel.

You can also stagger or overlap frequencies to tweak the response and compensate for any peaks or dips in your drivers.

Whether you're a DIY audio enthusiast building a bookshelf speaker or a car audio fan tuning your system, this crossover gives you clean, reliable filtering without breaking the bank.

Easy to install, built to last, and backed by a 5-year warranty—just add your drivers and enjoy the clarity.
