Positioned between the Model Three and Model Five, it combines the Model Three’s 8\" woofer with the 4\" midrange driver, 1\" aluminum-dome tweeter, and crossover architecture of the Model Five.\u003c\/p\u003e\n\u003cp\u003eIts sealed acoustic suspension enclosure provides controlled bass without requiring the generous rear clearance commonly needed by ported speakers. The cabinet measures just 8.25\" deep without its riser base, making the Model Four well suited to placement near a wall while preserving the wide-baffle proportions of KLH’s larger Model Collection speakers.\u003c\/p\u003e\n\u003ch4\u003eThree-Way Acoustic Suspension Design\u003c\/h4\u003e\n\u003cp\u003eAn 8\" pulp-paper cone woofer extends the frequency response down to 46 Hz, while a dedicated 4\" pulp-paper cone midrange handles the critical vocal range. A 1\" aluminum-dome tweeter completes the three-way system, allowing each driver to operate across a more focused portion of the frequency spectrum.\u003c\/p\u003e\n\u003ch4\u003eAcoustic Balance Control\u003c\/h4\u003e\n\u003cp\u003eThe three-position Acoustic Balance Control lets you adjust the speaker’s midrange and high-frequency output to suit the room, speaker placement, and listening position.
