Monaco 215 CX SP by Outline is designed and manufactured with the same stringent quality standards applied to Outline’s world class touring audio products. Contemporary design and efficient manufacturing processes allow Outline to deliver these products with first-class power handling and audio fidelity at a very attractive price point. Monaco 215 CX SP is an ideal self-powered multi-purpose, full-range, two-and-a-half-way bass reflex enclosure equipped with a modern premium custom coaxial driver.

Outline’s high quality coaxial driver gives excellent sonic performance, increased timbre quality and high power handling characteristics. It is loaded by a proprietary moulded waveguide, which is coaxial to the 15” mid-woofer and provides low-pass acoustical loading on the woofer, increasing the efficiency in its usable bandwidth. Uniquely configured as a ‘two-and-a-half’ way system both electrically and acoustically, Monaco 215 CX SP delivers audio performance approaching a three-way design with extended low frequency.

The all-wood 15 mm phenolic-glued Baltic birch enclosure features craftsmanship dovetail joinery construction protected by an epoxy powder coated, resonance-free steel grill over acoustically transparent foam. Every cabinet is coated with a high-tech black textured polyurea scratch free finish and custom RAL color repainting options are available for installations with specific cosmetic requirements.

The built-in amplifier platform with four selectable EQ presets and input gain enables to use this enclosure as part of a plug & play solution. The maximum available power from the amplifier module is 1500 W EIAJ at 4 ohm, 3000 W peak.
