Precise impedance matching and stable signal transmission Ohmic interfaces provide precise 4Ω/8Ω impedance adaptation, reducing contact resistance to deliver clear, stable transmission between the amplifier and the loudspeaker unit. Twoway /low frequency separation with adjustable crossover Builtin second crossover network with an adjustable crossover point, typically 2.5 kHz to 3 kHz. Enables a smooth 3 dB transition between and low frequencies and helps prevent frequency band overlapping distortions. Integrated junction box for quick installation Integrated junction box design includes solderless terminal blocks and antishortcircuit protection covers. Supports quick insertion and installation and simplifies modifications. HiFi component configuration for clear sound Uses metal film capacitors and large power resistors. Frequency response from 20 Hz to 20 kHz and total harmonic distortion ≤ 0.5%. Key specifications and features Impedance compatibility: 4Ω or 8Ω available Crossover: second; adjustable cross point around 2.5 kHz–3 kHz; 3 dB at crossover Enclosure: integrated junction box with solderless terminals and antishort protection covers Frequency response: 20 Hz–20 kHz Total harmonic distortion: ≤ 0.5% Components: metal film capacitors and large power resistors Practical use scenarios Home stereo upgrade: Pair with 4Ω or 8Ω bookshelf or floorstanding speakers to improve signal clarity and drive stability with compatible amplifiers. DIY speaker project: Compact, easytoinstall crossover module that supports quick adjustments and straightforward modifications. Home theater system: Route frontchannel speakers through a precise crossover to ensure accurate frequency separation and reduce interchannel distortion. Notes on compatibility and performance Maintains consistent performance across 4Ω and 8Ω loads. Designed to deliver clear and midrange detail while preserving bass response within the 20 Hz–20 kHz range. Built to minimize distortion, supporting reliable listening across typical hifi and home theater applications.
