HA-304 is a passive line source column speaker with an elegant and charming compact column design. The cylindrical surface uses a unique cylindrical wave diffusion technology, which has the advantage of avoiding the rapid attenuation of sound. The acoustic coupling of a single sound source, the sound is widely and evenly distributed, and the projection distance is longer. Its characteristic is to reproduce the sound accurately and naturally.

The HA-304 speaker consists of 3 linearly arranged 3" mid-bass units and 1 3" conical paper cone tweeter unit. The cabinet is made of MDF board, and the plates are spliced by mortise and tenon structure. The mesh cover is a powder-coated perforated metal material, and the bottom is equipped with a single-hole 35mm base to support the application of a three-legged support frame.

On the left and right sides and the back of the column speaker, there are 2 M8 lifting screws with a spacing of 100mm, which can be used for horizontal or vertical lifting and independent applications using commercially available hangers.

This HA-304 speaker can be used alone or in combination with the subwoofer series of low-frequency speakers in this family.
