Using a 5-way split sound, a special 2 "+1" coaxial horn, a full brass and titanium alloy voice coil made of 16mm ultra-treble unit, two special 15-inch dipole type design bass, its sensitivity is up to 98.5dB, can provide stable and highly consistent acoustic output in the range of 27HZ-40000Hz (+/ -3dB).

Adopted the world rare concentric compression drive, with a single horn design, compared with the ordinary horn speaker, its unique bugle shape and size can be achieved excellent sound waves and excellent off-axis response, guarantee the directivity of the stability of the horn tweeters have, like voices like mouth, make the sound field of sound is very clear, right can keep the dimensional feeling of original recordings and presence.

Roma Triode USES extremely expensive components such as state-of-the-art ebony horns, all-brass and titanium sound coils for ultra-high pitch units, luxury pure silver coil capacitors, whole top solid Italian walnut front baffle design, golden all-brass bass baffle, pure wool materials, etc.

Patented materials exclusively developed by Diesis Audio CLAD 58 are made of special materials solidified in a single die to ensure their excellent hardness and damping properties. When output at the same sound pressure, they will not generate excessive vibration diffusion like solid wood materials.

Adopt the world's first in the dipole model bass sound unit with high compression unit horn fusion for the integration of technology, low frequency by two 15-inch diameter of dipole more efficient design bass unit combination and become, dipole unit type is the best sound quality performance, its sound is very natural, even in low power output and low pressure also have a good voice. In addition, its large-caliber special bass unit has short front and rear stroke and fast speed response, which can cooperate with the speed response consistency of the compressed horn treble unit, reducing the negative effect of low-frequency standing waves, but bringing a rare sense of looseness.
