Dayton Audio OPAL1 2-Way Hi-Fi Bookshelf Speaker Pair
Since its establishment, Dayton Audio has been synonymous with premier loudspeaker components, and ready-to-build designs. During our research and development process to develop new and interesting loudspeaker concepts one design reigned supreme – the OPAL1. This system embodies our commitment to innovation, exclusively incorporating Dayton Audio’s technology, ensuring an audio experience that is both authentic and groundbreaking.

MMAG Woofer: The Heart of Clarity and Power
At the heart of the Dayton Audio OPAL1 speaker lies a woofer that utilizes dual-gap MMAG (Multiple Magnetic Air Gap) technology. This motor technology combined with extensive venting allows for extreme cone excursion and control, low distortion and higher-than-average power handling. A stiff but lightweight carbon fiber cone and specifically engineered surround profile allow incredibly smooth midrange performance, something unheard of on a 5-1/2” woofer with this kind of excursion capability.

High angle of tweeter
Silk Dome Tweeter
The top octaves of the OPAL1 are handled by Dayton Audio's premier silk dome tweeter. It incorporates a coated silk dome mounted to a vented aluminum voice coil former for increased power handing. A copper cap and sleeve surround the gap to reduce eddy currents and reduce distortion, while a large damped rear chamber help extend the low-end response. An asymmetric crossover centered at 2,300Hz marries the tweeter and woofer together, providing a smooth, non-fatiguing, ultra transparent and huge sound that is usually only found in larger tower speakers. The sound of the OPAL1 defies its size.

Passive Radiators for Room Filling Bass
The bass extension of the OPAL1 comes from the use of a pair of passive radiators on the rear of the enclosure. These allow for ultra-low frequency extension in a small package, besting many 6-1/2” or 8” bookshelf speakers, or even small towers. With a footprint of less than 67 square inches, the OPAL1 is capable of average in-room extension nearing 30 Hz. This means in many applications these speakers can create room-filling bass without the need of a separate subwoofer. With an RMS power handling of 200 watts, they can achieve output capability beyond most bookshelf speakers of this size.

Exquisite Cabinet Design with Attention to Detail
The cabinets of the OPAL1 may be small in stature but are solid as a rock. Using ¾” MDF throughout, and internally braced construction, the cabinets will not color the sound by introducing their own vibrations. The calculated addition of damping material on the inside also helps reduce standing waves which can add unwanted resonances.

Continuing the attention to detail; the inside edges of the grills have been heavily chamfered in order to reduce diffraction when in use. The grills are securely attached with hidden magnets, so when they are removed, the OPAL1 has a clean, uniform appearance.
