the apparatus.

11. Only use attachments/accessories speciﬁed by the manufacturer.

12. Use only with the cart, stand, tripod, bracket or table speciﬁed by the manufacturer or sold with the apparatus.

When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualiﬁed service personnel. Servicing is required when the apparatus has been damaged in any way, such as power

supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, or the apparatus has been exposed to rain or

moisture, does not operate normally or has been dropped.

15. Do not expose this apparatus to dripping or splashing and ensure that no objects ﬁlled with liquids, such as vases, are placed on the apparatus.

16. To completely disconnect this apparatus from the AC Mains, disconnect the power supply cord plug from the AC receptacle.

17. The mains plug of the power supply cord shall remain readily operable.

18. Do not expose batteries to excessive heat such as sunshine, ﬁre or the like.

The lightning ﬂash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated

“dangerous voltage” within the product’s enclosure that may be of sufﬁcient magnitude to constitute a risk of electric shock to

persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and

maintenance (servicing) instructions in the literature accompanying the product.

WARNING: To reduce the risk of ﬁre or electric shock, do not expose this apparatus to rain or moisture.

ABOUT THE REVEL® CONCERTA™

B1 SUBWOOFER

Thank you for purchasing the Revel Concerta B1, a high-performance

powered subwoofer that perfectly augments Revel Concerta Series

loudspeakers in stereo music or home theater entertainment systems.

The B1’s adjustable controls and multiple connection options also

allow you to optimize the subwoofer’s performance in any system and

listening room.

Featuring a 12" (305mm) woofer with 1-1/2" (38.1mm) peak-to-peak

excursion and powered by a 250-watt ampliﬁer, the B1 subwoofer

reproduces deep, realistic bass with very low distortion, even at the

lowest frequencies and high output levels.

Combining superior form and function, the B1’s proprietary woofer is

constructed with an anodized-aluminum diaphragm for great strength at

high output levels. The spider incorporates a superior-strength Nomex®/

cotton blend with optimized geometry for increased linearity. The motor

includes a large ceramic-magnet motor system. A 2" (50.8mm) copper

voice coil is wound on a Kapton® bobbin for impressive power handling

and freedom from compression. The vented center pole facilitates

heat dissipation, allowing more efﬁcient high-power handling and low

compression.

The B1 cabinet consists of medium-density ﬁberboard (MDF) walls and

extensive internal bracing to reduce cabinet-induced colorations. Rubber

padded feet are attached to the bottom of the cabinet for optimal

stability, accommodating installations on any ﬂoor surface.

Since 1996, the Revel brand has been at the forefront of loudspeaker

design. Backed by Harman International’s extensive research and design

facilities, Revel Concerta Series speakers beneﬁt from cutting-edge

development tools, such as:

• A multichannel listening lab allows for double-blind listening tests.

• A laser interferometer enables detailed driver and cabinet analysis.

• Multiple large anechoic chambers provide for precise tests and

measurements.

• Finite-element analysis allows for advanced loudspeaker modeling.

• A stereo lithography apparatus aids in achieving tight tolerances.

Adding to the proud lineage of Revel Ultima™ and Performa™ Series

loudspeakers, the Concerta B1 subwoofer further substantiates the

Revel reputation for high-quality, high-performance loudspeakers and

subwoofers.

SUBWOOFER PLACEMENT

Below 300Hz, loudspeaker and listener locations have a profound impact

on the way sound is reproduced. All rooms have “standing waves,” by

which certain frequencies are emphasized or diminished. Their complex

patterns can combine to introduce tremendous sound coloration at low

frequencies.

The Concerta B1’s Equalization controls can help to compensate for

these effects, but no electronic system alone can fully compensate for

the dramatic effects of room acoustics. Every room has locations where

“nulls” at speciﬁc frequencies occur. These cancellations of the sound

are like “black holes,” which no amount of equalization can ﬁll. The

best results are always achieved through careful placement of both the

loudspeakers and the listening position. Preferable placement can be

determined through the use of computer modeling programs, or by trial-

and-error measurements. For optimal results, ﬁnd the best loudspeaker

and listener locations ﬁrst, then use the B1 Equalization controls for

ﬁne-tune adjustments.

To help determine good locations for the subwoofer(s) and the

listener(s), it is recommended that you make high-resolution in-room

response measurements. Your authorized Revel dealer can make the

appropriate measurements, using suitable equipment to ensure optimal

results.

NOTE: Many sound-measurement devices are not accurate

enough to properly measure low-frequency performance in a

listening room, since room boundaries can often cause modes

(standing waves) with very narrow-band peaks and dips.

Check with your authorized Revel dealer to conﬁrm that your

measurement equipment is suitable for accurate, high-resolution

measurements.
