Audiophile Theater Speakers

All units are sonically matched within ±2 dB for seamless multi-channel playback.
JAM Monitor
The performance and output of this speaker belies its size. Sized to fit discretely in cabinetry, the Monitors play loud enough to fill a 5,000 ft3 room, and produce bass to 38Hz. Designed to run full-range, Monitors add two additional sources of bass to the theater, smoothing out bass nulls and increasing impact.
JAM Center
Tuned for vocal articulation, this speaker uses a vertically aligned tweeter/midrange assembly for smooth horizontal coverage. We eliminate comb filtering in the midrange, so you hear dialog and on-screen effects clearly throughout the listening area. Voices are life-like, and effects are clean and distinct. Dual bass units provide bass to 49Hz.
JAM Active Subwoofer
We take special pride in this theater subwoofer. Unlike most subs, ours is free of limiting and soft-clipping circuits which rob a subwoofer of its attack. (Engineers include these devices to overcome deficiencies in their systems.) We took a different approach, and designed a 500w high-current amplifier and long-throw bass unit with a
machined aluminum cone to work together perfectly. This results in a subwoofer that produces articulate bass, and plenty of
it.
The JAM Sub is compact enough to fit into cabinets and behind furniture. The optional down-firing tray permits placement behind kick-panels for a completely concealed look.

An audiophile 24/dB octave low-pass filter permits precise blending with the Monitors, eliminating any gaps between the speakers.
Choose the BeBop when using a box speaker for the surround channel. It’s matched to the Monitor and Center for smooth front to back pans. The BeBop has a 3/8x20" insert for wall or ceiling placement.

We spec our theaters with two pair of surrounds. We aim one pair for direct sound, the other is aimed to produce a diffuse field. This combination replicates a dubbing studio for accurate soundtrack reproduction. We especially like the feeling of “fullness” from two pair of surrounds.
The JAM Theater includes the JAM Monitor,
JAM Center Channel, JAM Subwoofer, and BeBop
for surround.
