IsoAcoustics Aperta Support Plate

• A single 5.25-inch paper cone woofer doped for stability and damping.
• Precision Vojtko™ crossover with custom air core coil and low DCR steel laminate inductors; polyester film and low DF electrolytic capacitors.
• Designed to easily corner mount, wall mount or angle-wall mount for versatile placement in any room.
• Convenient push-style binding posts easily adapt to accept banana plugs.

• The ElectroMotion Architectural Series features MartinLogan's award-winning Folded Motion thin film transducer technology to take acoustical performance to a new level with in-wall and in-ceiling applications.
• With Folded Motion tweeter technology, response time is drastically reduced with the use of a pleated diaphragm that "squeezes" air to create sound, almost like an accordion.
• The sturdy mounting-lock system allows for quick, hassle-free installation with firm coupling of the speaker's chassis to the ceiling. When removing the speaker, the locks retract and latch themselves back in their housings.

Expanding the Dynamics of Center Channel Performance By adding a compact electrostatic panel to a center channel speaker, MartinLogan engineers have succeeded in expanding the performance dynamics of the most important speaker in your home theater system. Your center channel speaker needs to be able to reproduce the finest high-frequency details. The midrange must be expansive; to reproduce every whisper of dialogue. Deep bass adds impact to the front-stage effects that anchor the action to your screen. The EM-ESL C accomplishes all this and more. The EM-ESL C has a shallow height CLS (Curvilinear Line Source) XStat electrostatic panel wrapped around the front of the speaker enclosure. The gentle horizontal curve of the panel enhances the output of its deceptively compact 114-square-inch radiating area, extending mid-range dispersion patterns and blending the performance seamlessly with your front-stage ElectroMotion loudspeakers. Just behind the electrostatic panel, in a specially designed housing, sits MartinLogan’s exclusive Folded Motion Tweeter. The low-mass diaphragm of the Folded Motion Tweeter minimizes distortion, and its short excursion length reinforces its lightning-fast high-frequency response. The 1 x 1.4-inch Folded Motion Tweeter in the EM-ESL C has a total diaphragm area of 9.2-inches, with the ability to reproduce precise details; one of the most important jobs of a center channel speaker. The New CenterForce System Designing a high-performance electrostatic center channel speaker sized to fit into A/V furniture was no easy task. Adding a dual woofer system seemed impossible! But MartinLogan’s skilled audio engineers found a novel solution, and they call it CenterForce. Instead of taking up space by positioning the woofers on each side of the electrostatic panel, they’ve designed a central slot inside the cabinet for the woofers. Now, the dual woofers reside in a well-braced enclosure located behind the tweeter and electrostatic panel. This new CenterForce solution allows the speaker to be more compact and encourages the woofers to produce a generous amount of well-blended deep bass. The CenterForce system in the EM-ESL C features two custom-designed 5.25-inch aluminum cone woofers. Rigid and yet lightweight, this material reduces flexure while minimizing response time. Their efficient construction optimizes suspension and magnetic flux field, further reducing potential sources of distortion. The EM-ESL C grounds its performance in accurate, musical bass response. This is a center channel speaker that delivers a full-range performance, by combining an electrostatic panel with a Folded Motion Tweeter, bolstered by the CenterForce bass system. The compact EM-ESL C goes where you want it, and does what you need, for your high-performance ElectroMotion home theater system.

• A single 6.5-inch doped fiber-cone woofer provides a powerful low-frequency extension.
• Designed to easily corner mount, wall mount or angle-wall mount for versatile placement in any room.

The ForceField Subwoofers’ unique and attractive cabinet shape, with its non-parallel cabinet walls (the top is narrower than the bottom when viewed from the front), helps the ForceField subs achieve extraordinarily deep and tuneful bass that is ideal for music and movies. Their cutting-edge amplifier design employs state-of-the-art DSP control for frequency shaping so the subwoofer produces accurate, consistent and musical bass performance. Many of today's subwoofers fall into either the ultra-compact high-output category, or the (larger) high performance, extended response, high-output category. These two design types tend to offer different performance benefits, the ultra compact having the ability to play extremely loud, but over a narrower bandwidth and the large subs having this high output plus more extended response. GoldenEar's engineering team set out to accomplish the best of both worlds with the new ForceField subwoofers: small size, yet with the smooth & wide response of a larger sub. There's no sleight of hand, just great engineering - all ForceField subwoofers share the same technologies, here is a list of their features. Read through these and then take a good demo disc into your GoldenEar dealer's sound room and listen for yourself.

• Custom-designed high-output drivers with very large motor assemblies. These drivers handle massive power, have very long excursions, and have ultra-low distortion.
• Rigid cabinets with non-parallel sides to minimize standing waves and distortion. The drivers are front firing in all of our subwoofers for optimal performance. The cabinets' possess a unique and understated shape and style that matches well with any décor.
• The driver's response is enhanced with a carefully tuned, down-firing, quadratic-shaped passive radiator (no noisy ports on ForceField subs). The quadratic shape allows the radiators to use maximum surface area on the bottom of the cabinets and gets even greater output from the slot-loading that results from the subwoofers' interface with the floor (see next point).
• The soft, energy-absorbing feet provided with every ForceField sub serve a number of functions. First, they hold the subwoofer at the correct distance off the floor so the passive radiator slot-loads with it for significantly increased output at the lowest frequencies. Second, the soft feet keep the subwoofer from dancing around on the floor. ForceField subwoofer amplifiers are designed in-house by GoldenEar engineering, so each is the perfect amp to power its specific subwoofer model.
• In addition, the amps all have powerful DSP sections to optimize frequency response, minimize distortion and prevent damage from overdriving. These amplifiers are all low distortion and extraordinarily powerful (up to 1500 watts on the ForceField 5) for reproducing seriously high-output AND low bass.
• ForceField subs all have speaker-level inputs and outputs (with a high pass crossover on the outputs) as well as a direct LFE input, too.
• Non-parallel sides minimize standing waves and distortion. The shape allows the radiators to use maximum surface area on the bottom of the cabinets and gets even greater output from the slot-loading that results from the subwoofers' interface with the floor.
• Features 1200-watt digital amp, a front-mounted high-power ultra-long-throw 10" sub-bass driver coupled to a downward-firing 11"x 13-7/8" quadratic planar infrasonic radiator.
