INTRODUCTION

Revel®leads the loudspeaker world in research, advanced

engineering techniques, and unique production processes. The

REVEL PERFORMA™M20 loudspeaker is the perfect demon-

stration of Revel’s unparalleled engineering capabilities.

The REVEL PERFORMA M20 loudspeaker is a compact model

with technology derived from advanced engineering used in Revel’s

famed Ultima™ loudspeakers. Each one has an inverted magnesium-

alloy dome woofer and custom aluminum-alloy dome tweeter to

achieve outstanding freedom from coloration. We also use our

groundbreaking measurement process to seamlessly integrate the

superb transducers with an optimized network to achieve stunning

realism and superb dynamics.

As a result, the REVEL PERFORMA M20 loudspeaker sets a

whole new standard in bookshelf loudspeaker sound quality. Its

superior performance, assured by our ongoing research, will greatly

contribute to the enjoyment of music or film sound in your home.

ABOUT THE MANUAL AND WARRANTY

To begin enjoying your new loudspeakers, first read and then perform

the instructions in this owner’s manual. Maximum performance

depends on following all instructions described here, as well as those

found in the owner’s manuals of associated components in your audio

system. Save these instructions for future reference.

REVEL PERFORMA M20 loudspeakers are covered by a limited

5-year warranty, so save the bill of sale to protect your purchase

and aid in any service-related questions.

DESCRIPTION

The REVEL PERFORMA M20 loudspeaker features a transducer

complement (see Figure 2) of one 6.5-inch (165 mm) woofer and a

1-inch (25 mm) tweeter.

Combined with an individually-optimized crossover network, this

transducer arrangement results in a superior off-axis response that

provides a large “listening window” and an uncolored in-room

response, even in the presence of strong wall reflections.

WOOFER

The 6.5-inch (165 mm) woofer with an inverted magnesium-alloy

dome features:

• True pistonic operation for increased freedom from coloration.

• Shielded magnetic circuits to prevent interference with

video monitors.

• Butyl rubber surround for large, linear excursion capabilities.

• Vented center-pole piece for better cooling and low compression.

• Die-cast basket to eliminate resonances.

• 1.5-inch (38 mm) Kapton®voice-coil former with flat, edge-

wound voice coil.

• 26-ounce (0.737 kg) motor system with flux shorting ring to

dramatically reduce modulation distortion.

• True pistonic operation for increased freedom from coloration.

• Underhung with copper-clad aluminum wire for low distortion.

• Ferrofluid for better power handling with reduced compression.

• Shielded magnetic circuits to prevent interference with

video monitors.

• Flux modulation ring for very low distortion

CROSSOVER NETWORK

Each REVEL PERFORMA M20 loudspeaker has an individually-

optimized crossover network with:

• A high-order crossover at 2.2 kHz to optimize the on- and off-

axis response of the system.

• Filter networks with carefully selected components for optimum

performance with vanishingly low coloration and distortion.

• External Placement Compensation Control for optimizing the

loudspeaker’s response for flush-mount, bookshelf, or stand-

mount applications.

• External Tweeter Level Control provides high-frequency com-

pensation for a variety of room environments.

CABINET

The cabinet is constructed of 1-inch (25 mm) thick MDF walls

with extensive internal bracing for unshakable performance.

A rounded front baffle is sculpted to reduce diffraction, and three

cast aluminum feet adorn the cabinet for superior coupling to any

surface. The wood-veneer cabinet comes in finishes of Cherry,

Sycamore, Rose, or Black Ash.

The optional REVEL PERFORMA PEDESTAL 1 is also available

from your Revel dealer. This stand is designed to optimize the

acoustical performance and enhance the appearance of the REVEL

PERFORMA M20 loudspeaker. It attaches securely to the loud-

speaker cabinet, and the loudspeaker feet attach to the base of the

stand to create an integrated and attractive appearance (also see

Installing Stands on page 8).

UNPACKING

IMPORTANT! To avoid injury, please use care during unpacking.

Always stand as straight as possible and use your leg muscles to lift

the REVEL PERFORMA M20 loudspeaker. Do not lift it while

bending from the waist.

Each REVEL PERFORMA M20 loudspeaker is packed in its own

carton. To unpack it, perform the following steps:

1. Place a REVEL PERFORMA M20 loudspeaker onto its side.

2. Open the bottom flaps. Stand the unit in the up position.

3. Open the top flaps. Take out the spike foot kit and set it aside.

Remove the top pad.

4. Lift the carton off the loudspeaker and set it aside, being careful

not to damage the cabinet.

5. Grasping the cabinet on the sides, lift it up and remove the bot-

tom pad. Use caution to avoid touching any of the transducers.

6. Repeat steps 1 through 5 for the other loudspeaker.

NOTE: Spikes can be installed as an option after determining final

speaker placement. Installation is similar to instructions shown in

Figure 7 on page 9.

After unpacking both units, carefully inspect each one for possible

damage due to shipping. If you discover any damage, immediately

contact your Revel dealer for further assistance. When moving a

REVEL PERFORMA M20 loudspeaker (e.g., when experimenting

with placement), avoid touching the tweeter and woofer.

Keep all packing materials for future shipping. In the unlikely

event a product will need repair, Revel will only accept a unit in its

original shipping carton. Using any other packing materials may

result in damage to the product and is not covered by the warranty.

See Service Information on page 17 for additional details.

INSTALLING GRILLES (OPTIONAL)

If desired, install an optional grille onto each REVEL PERFORMA

M20 loudspeaker, as shown in Figure 4 below.

INSTALLING STANDS (OPTIONAL)

1. Using a Phillips screwdriver, remove the REVEL PERFORMA

M20 loudspeaker feet and screws (for later attachment to stand

base). Locate the parts bag (packed with the loudspeaker) that

contains spikes, lock nuts, covers, and a wrench. Set all parts aside.

2. Unpack a REVEL PERFORMA PEDESTAL 1 box. Start the

stand assembly by fastening three upright bars to the bottom ‘T’

base with the enclosed 1 ⁄ 4-20 x 1" flat head screws, as shown in

Figure 5.

3. Place the stand in its upright position. Install the top plate with

three 1 ⁄ 4-20 x 1" flat head screws, as shown in Figure 6.

4. Place the stand as shown in Figure 7 and install the feet (from

Step 1) onto the bottom of the ‘T’ base. Thread spikes about

halfway into each foot and use the wrench to tighten each one

with a locking nut (see details below).

5. Place your REVEL PERFORMA M20 loudspeaker as shown in

Figure 8 onto a carpeted surface or soft towel. Attach the assem-

bled stand with three 8-32 x 3⁄4" flat head screws. Turn the

unit upright. Repeat all steps for the other stand.

PLACEMENT

Sound quality is heavily dependent on the accuracy of your loudspeak-

ers, their placement in the listening room, and the acoustics of the

room itself. Since the REVEL PERFORMA M20 loudspeakers are

extremely accurate, experimenting with their placement is the most

significant way to optimize their performance in a given environment.

The following guidelines will help you obtain the best results:

NOTE: The REVEL PERFORMA M20 includes a user-adjustable

placement compensation circuit that tailors the response for a desired

application (e.g., stand mounting or mounted in or near a wall, such

as on bookshelves or in a custom installation). See “System

Optimization” on page 15 for details.

• For best stereo imaging, place the REVEL PERFORMA M20

loudspeakers at equal distances from the main listening position

and in symmetry with the room, as shown in Figure 9.

• Optionally, use a pair of REVEL PERFORMA PEDESTAL 1s

to solidly mount the REVEL PERFORMA M20s at an ideal

height for seated listeners, as shown in Figure 10.
