Several technologies set Nola's loudspeakers apart from the competition. They include:
Nola's open baffle loudspeakers feature midranges and tweeters
that operate in dipole mode, using a cone driver without an
enclosure. This system eliminates four major resonant problems that
hamper all midrange enclosure systems and cause the sound to take on a
mechanical coloration:

Here is an example of a common boxed speaker design, with the forward wave in red, and the rear wave in blue. Notice how the rear wave bounces off the cabinet and recombines later with the forward wave, adding coloration to the sound. This resulting coloration blurs detail and adds a mechanical, boxy quality to the sound.
This is an example of a speaker driver operating in dipole
mode. Note that the rear wave doesn't interfere with the forward
wave. The result is an "open," natural, and clear sound with
excellent depth and soundstage performance.
Many Nola loudspeakers feature premium cobalt (alnico) magnets. The powerful field generated by these magnets contributes to the natural reproduction of harmonic textures.
Multiboard Hand-wired Crossovers
Nola loudspeakers feature hand-wired crossovers without fuses or current-limiting devices, which would compromise signal integrity. The tri-wired speakers use three separate boards, oriented in space so that they do not interfere with each other. This is a true tri-wired system - from the drivers back to the amplifier - for minimum possible distortion and coloration. The bi-wired systems use two separate crossover boards to create a true bi-wired system.
Nola's reference-model loudspeakers use an external crossover module for improved performance. The external crossover prevents colorations due to interactions between the driver magnets and crossover components, and also prevents mechanical vibration of the crossover components for a smoother, more open sound.
Multi-Wiring is a method of connecting loudspeakers to an amplifier (or amplifiers) for improved clarity and detail. Each driver or set of drivers in the loudspeaker has its own independent set of cables for connection to the amplifier. This separation of electrical connections to the drivers prevents distortions and colorations due to circulating currents within the loudspeaker, and reduces intermodulation distortions within the speaker cables. Multi-Wiring also allows the use of specialized cable constructions, optimized for different frequency ranges to attain better performance. For example, in the Blue Thunder speaker cable, the low-frequency cable uses a coaxial construction with both solid core and stranded silver wire, while the high-frequency section uses a uniaxial construction of stranded silver wire, resulting in improved openness and clarity.
With all of Nola's products, the use of Blue Thunder speaker cable in single, bi-wire, or tri-wire configurations is strongly recommended for best performance. Mismatched cables can cause sonic distortions, such as boomy bass, hard midrange, bright or dull treble, poor sound staging, nasality, poor dynamics and veiled sound.
All Nola products, including Blue Thunder cable, require a minimum of 100 hours use with music before speakers and cables will settle down to their final performance. During this break-in period the sound will usually be somewhat tight and constrained. As the system breaks in you will notice an increase in ease and openness to the sound, with improved dynamics.
