"The Naos loudspeaker was in development for over 5 years and it is easily Rega’s finest loudspeaker to date. This two-way transmission line design incorporates a tweeter which is totally unique in this approach to pole piece design. No ferrofluid, which removes unnecessary dampening, is used. The Tweeter is specially designed to complement the new 8-inch Drive Unit which is manufactured by Rega using a cast aluminium basket and 8-inch paper cone. The paper cone is a special design and is sourced from Kurt Mueller of Germany. The crossover contains only two coils and one capacitor in the signal path. The cabinet is made of veneered MDF with a unique diagonal transmission line. The bi-wireable Naos is a extremely accurate in the high and low frequencies." ( From original Rega brochure c. 1999 ) I use my pair in a dedicated room, with a Silk Audio (Yaqin) EL34 tube amp. They are supported on Soundocity outriggers. They do indeed have bass extension to 27hz without the boom of bass reflex designs. The sound is natural and open, with a pleasant bloom. This is my baroque system. (For reggae I use a pair of RELpowered subs ;-)

Be careful with the bass driver phase plug. Keep the driver clean: The voice coil is not protected by a dust cap.

BASS! High end sound and build quality Very good with music.

Kinda boxy, so it's not the prettiest speaker in the world.

The Rega Naos is an awesome speaker. I use it for for my HT fronts. The most impressive aspect of these speakers is the bass. The transmission line design is incredible. At first, I didn't believe that a single 8" woofer in each speaker would go down flat to 25 Hz. Now it seems like I have an extra subwoofer in the front stage. They also sound very good with music, if fed with the right components. These speakers are clearly designed for larger rooms, so if you have a small or medium size room, you may not realize the full potential of the speaker.

separation, clarity, imaging

none yet.. perhaps not warm and enveloping, but not an issue for me

I am quite impressed with these speakers! I wasnt sure what to expect.. the whole 'quarter wave transmission line' thing.. but hey.. it works.. beautiful imaging. exquisite clarity. this is just the first review of this speaker, I just got them today, and I'm still new at audiophile vocabulary. But anyone should definitely audition these if given the chance, bass is clean precise and proper. Mids and highs beautifully balanced and precise. First heard these on an Rega Mira 3. using them myself with a jolida 801 tube amp
