The Cello speaker delivers a very musical, engaging sound with a beautiful and natural midrange, tight articulate bass and nice open, pure and clear highs with excellent resolution and dynamics. The Cabinet is constructed utilizing thick high quality MDF, the front grooved baffle is designed to be low diffraction. The surface of cabinet is finished in expensive hardwood.
The cabinet of the Cello is optimized, both in appearance and acoustic design. The Cello's beautiful and unique cabinet design is intended to simulate the shape of a Cello. Due to its lack of parallel surfaces, this design is also beneficial sonically as it helps reduce standing waves and diffraction allowing the drivers to produce a very clean and pure sound. In addition, it's polygonal, non-equilateral shape allows for a narrow front baffle and an extremely rigid, non-resonant cabinet.
Ported on the bottom, the Cello delivers surprisingly deep, articulate bass. And the bass reflex underneath the cabinet mean it can be placed near a back wall, making it easier to integrate into your living space.

It employs an air motion tweeter and an air motion mid-treble, the size of diaphragm is 25mmx120mm, easily field-replaceable for the diaphragm. It also has a rear firing tweeter, Purified aluminum ribbon tweeter the size of aluminum ribbon (LWT):60mmx8.8mmx0.01mm. High power handling, high output, shielded design, easily field-replaceable for the ribbon.
