“Speaking of horn speaker sound, the V never mimicked the pinpoint propagation of a horn’s concentric driver, but the Valor does. The post-convergent array of the 4-inch NeoRibbon drivers do not allow for a sloppy result. Dare I say the concentric 14” resolves the informational landscape between the speakers realistically, while the array of Stereo Unfold drivers propelling their signal outwards renders the wider, peripheral imaging cleanly. Just as whatever is in our eyes’ focus is clear, while the periphery is softened, so also the space between the Valor’s towers is clear, while the periphery is less distinct. That is perfectly ok, as our hearing discerns the immediate effect and subjugates the secondary stimuli.”

Audiophiles who delight in mixing and matching components have largely rejected active speakers. And maybe at the upper end of our hobby they always will. But where space and design are considerations, I think the scenario is rosy for actives, in that they can make a major musical statement without blowing up the room décor. I couldn’t have been more impressed with the electrifying performance and value of the Elac Navis ARB-51. It’s one of the rare small compacts that you don’t have to scale back expectations to enjoy. So, audiophiles, you’re on notice. Elac’s latest is rising fast on my short list for next year’s Product of the Year Awards.”

“Most impressive about the D1.1s, as with my reference X1s is their ability to do a great job on less than pristine musical selections. These are musical speakers first, not audiophile speakers, limited to a few perfect tracks. Thanks to the incredibly low distortion in the Raidhos, these are speakers you can listen to all day long with no fatigue.

As mentioned earlier, the bass that these speakers can generate is of extremely high quality, and extends quite low, lower than the 50hz spec might suggest. Tracking through a long play list of hip hop, electronica, and classic rock tracks with plenty of low bass output was indeed satisfying, though with the Bryston amplifier’s 1000 watts per channel on tap, I did have to be careful not to bottom those little woofer cones!”

“Klipsch has divided the RP-8000F horn into two sections by the copper ring embedded into the horn. The inner section is a conical plastic piece which serves as the throat of the horn, and the outer section, the mouth of the horn, is a softer silicone piece that takes on a more orthogonal shape. The softer silicone material of the mouth is used to avoid bell resonances in the horn. The throat of the horn is a round conical shape in order to reduce early diffractions as the soundwave leaves the tweeter diaphragm. The squarish mouth shape governs its dispersion pattern. A 1” titanium dome tweeter is used to load the horn, and it uses what Klipsch calls the ‘Linear Travel Suspension’ system which is a carefully designed suspension that allows for larger excursions of the moving assembly before the suspension thwarts linear motion thereby incurring distortion. Titanium seems like a natural choice for the diaphragm material since the horn-loading and lower crossover point might be more than softer dome types such as fabric could withstand. The rear chamber of the tweeter is vented to allow backwave energy to better dissipate instead of being reflected back into the diaphragm which would also increase distortion. ”

“Once we’re happy with their positioning, we shake off any dust particles with a quick blast of Faithless’s dance classic Insomnia. And the Revels transport you back to the dancefloors of the 1990s in no time.

The track’s blipping bassline can be lost with poorer-sounding speakers. With the Revels, you’re left in no doubt of its presence. The F35s give those bass notes a satisfying texture and match the pace of the track beat for beat.”

“Revel describes DCC as “a plasma electrolytic oxidation process that uses a plasma discharge to create a coarse ceramic coating on both sides of the aluminum core. The deep ceramic layers sandwiching the aluminum core provide constrained layer damping that push cone breakup modes outside of the passband allowing the driver to maintain ideal pistonic motion throughout its range.” The DCC cones are coupled with an improved motor structure for greater efficiency, dynamic range, and power handling, with reduced distortion and compression. Last but not least, the crossovers in the PerformaBe series are high-order crossovers that utilize all film capacitors and air core inductors in the midrange and tweeter circuits.”
