The Revel F328Be is the flagship floorstanding loudspeaker from their award-winning PerformaBe series. The F328Be includes a 1-inch (25mm) beryllium tweeter driven by massive 85mm dual ceramic magnets. The powerful all-new tweeter and 6th-generation ceramic-coated, cast-aluminum Acoustic Lens waveguide seamlessly integrate with the directivity of the companion midrange driver resulting in greater efficiency, improved dynamic range, reduced distortion, and increased power handling compared to aluminum or titanium tweeters.

Beryllium - Element 4 on the Periodic Table - is a rare earth metal that is renowned for its remarkable physical properties that make it the ideal material for a high-frequency transducer. Compared to aluminum and titanium tweeter diaphragms, Beryllium offers 4.5 times the stiffness and three times more damping, and does so at only half of the weight. Beryllium tweeters are the centerpiece of the Revel PerformaBe loudspeaker series.

The 5.25-inch (130mm) midrange and triple 8-inch (200mm) aluminum cone woofers utilize Deep Ceramic Composite (DCC) cones for improved performance. DCC is 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. DCC cones combine with optimized motor magnetics to deliver improved mid- and low-frequency performance.

PerformaBe crossover networks utilize all film capacitors and air core inductors in the midrange and tweeter circuits. These premium components allow Revel's world-class engineers to extract nuances and details from music that would otherwise be lost. Combined with traditional Revel high-order crossover slopes and proprietary Acoustic Lens waveguide geometry, transducer integration is seamless.

F328Be top panels are painted in stylish metallic black with raised electroform badging. The loudspeakers are available in a choice of four high-gloss finishes for seamless integration into any décor: Black, White, Walnut, and Silver.

Tower of power

Revel's top PerformaBe Series tower, the F328Be, has arrived. An additional 8" woofer and increased cabinet height and volume give this mammoth floor-stander an advantage over its sibling, the F228BE, in sheer output and bass depth.

Its three 8" woofers, one 5-1/4" midrange driver, and signature beryllium tweeter are housed in a beautiful cabinet with thick walls and vibration-reducing internal bracing. This monolithic loudspeaker will render a transparent and detailed soundstage that is virtually distortion-free.

Exceptional dynamic range

This is a sensitive speaker that can faithfully reproduce every detail of a musical recording, at high or low volume. The F328Be can play whisper-quiet passages with subtlety and nuance. But it can also belt out super-charged beats and high-energy guitar or sax solos with zeal.

The magic all starts with the beryllium tweeter

One of the secrets to the F328Be's great sound is its uniquely designed beryllium tweeter. 

Beryllium is several times stiffer than aluminum or titanium tweeter diaphragms. And it's also super-lightweight, so it moves quickly and in a very controlled fashion — two key attributes of a high-quality tweeter. 

An acoustic lens waveguide for great sound in every seat

One of the best attributes of the F328Be is its off-axis listening. The beryllium tweeter uses an acoustic lens waveguide, which helps it produce remarkably accurate sound, even if you're sitting off to the side of the "sweet spot.”

When you invite friends over to listen to these beautiful speakers (and trust me, you'll want to), everyone in the room will enjoy terrific sound.

Impressively hard-hitting bass and accurate midrange

Revel paired its beryllium tweeter with three 8" Deep Ceramic Composite (DCC) aluminum cone woofers for deep, tightly controlled bass. A dedicated 5-1/4" DCC midrange driver bridges this speaker's lows and highs with smooth, well-blended sound.

Protected investment

Each F328Be ships in its own heavy-duty flight case with butterfly latches and wheels, so you can unbox it in place and transport it safely. Good thing — each speaker weighs just north of 112 pounds.

Tested by instrument and by ear

Revel's world-class speaker design and testing facility features an anechoic chamber and the latest high-tech measurement gear. But some of their most critical test instruments are the ears of their trained listening panel. When working on a new design, Revel's engineers set up a series of controlled auditions comparing their design to several competing speakers.

Speakers under comparison sit on a rotating platform, and each model is moved into the identical position by a computer-controlled belt drive system. An acoustically transparent screen hides the speakers from the listeners to avoid visual bias. These double-blind listening tests provide an essential reality check, and help the engineers correlate measurements with what listeners actually hear and prefer.
