About the EAW KF Series
The EAW KF Series brings together multiple sub-series of three-way loudspeakers, each applying that three-way design to particular requirements. Passive full-range models such as the KF364 and KF394 feature dual 10-in LF cones with vented, tuned spacing, a 1.4-in MF cone that is horn-loaded and coaxial with the HF, and a 1.4-in exit HF compression driver. The KF364 adds switch-configurable passive and bi-amp powering modes, neodymium components and NT upgrade capability. Line array modules including the KF720 and KF730 use sealed, phase-aligned woofer arrangements, horn-loaded mid and high frequency drivers, and symmetrical enclosure geometry for pattern control. The KF730 features 16-ohm impedance, allowing multiple cabinets to be driven from two amplifier channels, and incorporates EAW CSA and Focusing technologies alongside a high output-to-size ratio.
EAW KF Series — buyer FAQs
What is the EAW KF Series and what types of cabinet does it include?
The EAW KF Series is a family of three-way professional loudspeakers spanning two distinct cabinet types: passive full-range models and line array modules. Passive models such as the KF364 and KF394 use dual 10-in LF cones with vented, tuned spacing and horn-loaded compression drivers. Line array modules such as the KF720 and KF730 use sealed, phase-aligned woofer arrangements and symmetrical enclosures for consistent pattern control.
Who makes the EAW KF Series and where does it fit in the brand's output?
EAW, short for Eastern Acoustic Works, is an American loudspeaker manufacturer that designs sound reinforcement speakers, line arrays and related systems for concert, touring and installed applications. The KF Series sits within that professional reinforcement catalogue, grouping several sub-series, each applying a three-way driver configuration to a different application requirement, from compact line array modules to passive full-range cabinets.
How does the KF730 line array module differ from the KF720?
Both are three-way line array modules with sealed, phase-aligned woofers and symmetrical enclosures, but they use different driver complements. The KF720 carries dual 6-in LF cones and six 1-in dome tweeters, making it an ultra-compact format. The KF730 uses dual 10-in LF cones and dual 1-in exit HF compression drivers, and its 16-ohm impedance allows up to eight KF730 cabinets to be driven from just two amplifier channels.
What should I check when buying a used EAW KF Series cabinet?
Confirm which specific model you are buying, since driver sizes, powering modes and impedance vary across the range. For KF364 units, check whether the switch-configurable bi-amp mode functions correctly and whether the neodymium components show any damage. Verify that HF compression drivers and MF horns reproduce cleanly across their range. All listings on 10K Used carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide covers what to request before purchase.
How much does a used EAW KF Series loudspeaker cost?
Used prices for EAW KF Series cabinets vary depending on the specific model, its condition, age and whether accessories such as rigging hardware are included. Line array modules and passive full-range models occupy different price brackets within the series. The live listings on this page reflect current market pricing, and many listings include a Make an Offer option if you want to negotiate.
