STUDIO loudspeaker.

INTRODUCTION

The REVEL ULTIMA STUDIO™ sets an entirely new perfor-

mance and value reference in floorstanding loudspeakers. It champi-

ons our hallmark of remarkable musical precision and imaginative

industrial design. While REVEL ULTIMA STUDIO’s artistic sculpt

is unique, its visual performance can only begin to tell the story of

the achievement yielded by our unique development process.

Our advanced psychoacoustic research into the interaction of loud-

speaker and various placement options has resulted in “real-world”

performance unmatched by any loudspeaker. For example, to

insure compression-free operation during the most demanding pas-

sages, the REVEL ULTIMA STUDIO includes large voice coils in

each transducer, judiciously selected crossover points, and true

24 dB per octave networks. While the true test of any loudspeaker

is the sound it reproduces, we think you’ll agree that this “clean

slate” approach has yielded a truly exceptional outcome.

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 ULTIMA STUDIO 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

REVEL ULTIMA STUDIO features a transducer complement (see

Figure 2) of two 8-inch woofers, a 5.25-inch midrange driver, and

1.1-inch tweeter. A second 0.75-inch tweeter (on the rear) provides

added high-frequency energy to enhance overall “room response.”

Combined with an individually-optimized crossover network, this

transducer arrangement results in an extraordinary off-axis

response that provides a large “listening window” and an uncolored

in-room response, even in the presence of strong wall reflections.

WOOFERS

For uncompressed dynamic range, each REVEL ULTIMA STUDIO

uses two 8-inch mica/carbon-filled co-polymer dome woofers with:

• A radiating surface made of an injection-molded polymer mate-

rial with incredible stiffness and internal damping.

• Optimized magnetic circuits to minimize harmonic distortion.

• Oversized 1.5-inch diameter voice coil with flat aluminum wire

offer higher power handling and long excursion capability.

MIDRANGE

The 5.25-inch titanium-dome midrange features:

• A radiating surface made of titanium for true pistonic behavior

throughout its operating range.

• A motor system that utilizes neodymium magnets and a large

voice coil for exceptional performance.

• Oversized 2-inch diameter voice coils with flat aluminum wire

offer higher power handling than average-sized coils for greater

accuracy at high volume levels and during extended crescendos.

• The cast magnesium frame provides optimum voice coil cooling

and minimum reflections, while offering excellent rigidity.

TWEETERS

Each REVEL ULTIMA STUDIO also includes a pair of

high-performance tweeters with these features:

• True pistonic behavior throughout its entire operating range for

a new level of freedom from coloration.

• A front aluminum-alloy dome tweeter with a large voice coil and

oversized surround roll for higher power handling and longer

excursion capability with extraordinarily low-harmonic distortion.

• A rear textile dome tweeter that flattens the “in-room” response,

resulting in superior “air” and detail.

CROSSOVER NETWORK

Each REVEL ULTIMA STUDIO has an individually-optimized

crossover network with:

• A 3-way, 24 dB per octave crossover at 220 Hz and 2.2 kHz to

optimize the on- and off-axis response of the system.

• Hand-wired filter networks with air-core inductors and film capac-

itors to match each loudspeaker to the reference standard.

• Provision for bi-amplified and bi-wired applications via remov-

able external shorting straps on the gold-plated binding posts.

• External level controls for both the front and rear tweeters via

calibrated switched precision resistors for ideal imaging.

CABINET

The cabinet offers exquisite appearance and aids in overall system

performance. The main enclosure and internal bracing are

designed to act as an acoustically-inert platform for sound-wave

generation. Interchangeable side panels are available in a full array

of optional finishes when updating home decor (see Panel

Replacement on page 19).

ULTIMA STUDIO carton.

UNPACKING

IMPORTANT! Do not attempt to lift a REVEL ULTIMA

STUDIO from its packing carton alone – use at least two strong

people to unpack the product properly. To avoid injury, use

extreme care during unpacking. Always stand as straight as pos-

sible and use your leg muscles to lift the REVEL ULTIMA

STUDIO. Do not lift it while bending from the waist.

Each REVEL ULTIMA STUDIO is packed in its own carton with

a shipping weight of 164 pounds (74.5 kg). To avoid personal

injury and possible product damage, we strongly urge you to enlist

additional help before unpacking either carton.

To unpack a loudspeaker, perform the following steps:

1. Stand a REVEL ULTIMA STUDIO in an upright position.

2. Carefully remove all staples from rear flaps. Open the flaps and

tilt the unit forward so that the bottom flap can be positioned

under the carton, as shown in Figure 3.

3. Lay the unit on its back with all flaps open. Lift carton off the

unit and set it aside.

4. Place the REVEL ULTIMA STUDIO in an upright position

and then remove the four (4) foam packing strips from the

sides, as shown in Figure 4 (on the next page).

5. Tilt the cabinet forward and remove bottom rear end pad, using

caution to avoid touching the front tweeter or midrange.

6. Tilt the cabinet backward and remove bottom front end pad,

using caution to avoid touching the front tweeter or midrange.

7. Remove top end pad, fabric sock, and plastic bag from the grille,

using caution to avoid touching the front tweeter or midrange.

8. Remove enclosed hardware and optional top grille (if present)

from recessed pockets in the top end pad. Install the top grille,

as shown in Figure 5.

9. Repeat steps 1 through 8 for the other loudspeaker.

NOTE: We recommend installing spikes after determining final

speaker placement (see discussion starting on next page).

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. To move an

unpacked REVEL ULTIMA STUDIO (e.g., when experimenting

with placement), rock it side-to-side into place, using caution to

avoid touching the front tweeter and midrange.

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.

loudspeakers for stereo. Note sug-

gested room treatments due to the

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 ULTIMA STUDIO 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: Set all loudspeaker controls to “zero” position during place-

ment experimentation. If needed, refer to Figure 13 on page 17.

• For best stereo imaging, place the REVEL ULTIMA STUDIO

loudspeakers at equal distances from the main listening position

and in symmetry with the room, as shown in Figure 6.

• Optimum timbre and imaging precision is obtained with the

loudspeakers pointing almost directly toward the prime listen-

ing position. Some listeners prefer a wider “soundstage,” which

is achieved by reducing the toe-in angle, perhaps to the point of

aiming the loudspeakers straight ahead.

• Imaging and a sense of spaciousness will improve as the

loudspeakers are moved away from the wall behind the loud-

speakers and the side walls.

NOTE: You may then need to move the listening position back to

maintain the best stereo image.

• For more bass reinforcement, try moving the loudspeakers closer

to the back wall or corners (also see Room Acoustics on next page).

NOTE: You may then need to move the listening position forward

to maintain an acceptable stereo image.

• For best results, make sure there are no objects between the

REVEL ULTIMA STUDIO loudspeakers and the intended lis-

tening area (e.g., a coffee table in front of the listener will degrade

timbre and imaging). If possible, avoid placing the loudspeakers

near large objects, which can cause unwanted reflections.

• Ideally, the listening room should be acoustically neutral, nei-

ther producing any distinct echoes nor sounding completely

“dead” and lifeless (also see Room Treatment on the next page)

• After choosing a final placement, add the spikes (and covers, if

desired) as described in Installing Spikes on page 11.

ROOM ACOUSTICS

Listening rooms have a profound impact on sound quality, espe-

cially at low frequencies. In fact, a listening room can actually

dominate the sound quality below about 300 Hz. Ideally, a new

room being built from scratch would include optimized dimen-

sional ratios to minimize the effects of standing waves.

However, most installations will be made in existing rooms. In

these cases, your only solution is to take special care in selecting

both the speaker and prime listening locations, which will pay off

in superior low frequency performance. Often the difference

between poor and excellent results is the result of relatively small

adjustments in speaker and listener placements.

The interaction of loudspeakers and rooms is quite complex, as the

loudspeaker and listener are affected by two mechanisms. First,

nearby surfaces, or boundaries, cause large peaks and dips in low

frequency response. These peaks and dips can often range 12 dB or

more. Second, the loudspeaker and listener locations interact with

the standing waves, or room modes. These standing waves, or reso-

nances, also result in large response errors. There are no simple for-

mulas that take both mechanisms into account. Even computer

programs that analyze one or both factors still may not provide

you with the proper speaker or listener placement values.

Here’s where real-world experience counts. We suggest consulting

your Revel dealer for help in determining the optimum loudspeak-

er and listener placement for your listening room.

PLACEMENT (CONTINUED)

ROOM TREATMENT

REVEL ULTIMA STUDIO loudspeakers have very accurate off-

axis response, which minimizes any degradation caused by overly

“live” rooms. However, far superior performance will be achieved

by placing at least minimal acoustic treatment materials at the pri-

mary reflection points. Ideally, special acoustic absorbers should be

placed at the first reflection points on the side and front walls

along with either absorbers or diffusers at the first reflection points

on the rear wall. Short of using acoustic treatment materials, even

simple hanging rugs can be a great help in overly bright rooms.

Carpeting the floor area between the speakers and listener and

placing irregular surfaces, such as bookcases, will also help break

up strong reflections.

Since our ears and eyes are located on the same plane, we can use a

mirror (also known as the “mirror method”) to accurately deter-

mine the most important locations (the first reflection points) for

material treatment, as follows:

1. After the loudspeakers are placed, the listener should sit in the

prime listening position.

2. A second person should slide a mirror along the walls.

3. Note the locations at which the listener can see either of the

loudspeakers. These will be the reflection points that would

require acoustic treatment materials.

Using this method, find all treatment locations for side walls, front

wall, and rear wall with side walls taking priority. Where possible,

also determine the treatment locations for first ceiling reflections.

Your Revel dealer can recommend acoustic treatment materials,

and can help determine the best plan for your room. If it is a dedi-

cated listening room, qualified room treatment manufacturers or

even acousticians may be consulted for optimum results.

Remember, properly treated rooms provide dramatically better

results with any loudspeakers than untreated rooms.
