• CI Elite speaker use the X-PAL tweeter with exclusive Perforated Phase-Aligning PPA Tweeter Lens that protects the delicate pure-aluminum tweeter dome and acts as the Phase Plug, blocking out-of-phase frequencies for smoother, extended high frequencies with incredible detail and higher output.
• CI Elite tweeters are cooled by the original ultra-stable Ferrofluid, made exclusively by Ferrotec. Ferrofluid is a colloidal suspension of magnetic nano particles in a liquid carrier with low volatility and high thermal stability.
• CI Elite X-PAL brushed pure-aluminum cone woofers combine lightweight stiffness with high consistency for a greater degree of accuracy and smooth, uncolored frequency response. Matching concave dust caps ensuring more uniform dynamic response and a cleaner, modern aesthetic.
• Paradigm's patented Active Ridge Technology ART surrounds, made in-house and overmolded directly onto each cone, achieve greater excursion for a 3dB gain in distortion-free output (50% greater) compared to drivers with standard surrounds. Crafted from audiophile-grade injection-molded thermoplastic elastomer, ART surrounds are more durable and reliable, for a lifetime of superior sound.

• Dual Low Distortion Aluminum Cone Woofers in a sealed enclosure - rigid cast baskets and stiff cones eliminate distortion, while the high excursion, extended throw drive assemblies produce tremendous amounts of low end in a surprisingly compact, beautifully finished enclosure. Expression ESL 13A features dual 10-inch woofers extending down to 24Hz. Impression ESL 11A features dual 8-inch woofers extending down to 29Hz.
• Curvilinear Line Source (CLS) Electrostatic Panel - CLS technology is an essential element of every electrostatic loudspeaker MartinLogan has ever designed. Through our proprietary manufacturing methods we have built-in the panel's gentle horizontal curvature. This unique design enhances the high frequency detail and dispersion produced by the large radiating surface, without compromising overall sound quality. Electrostatic panels, which are true dipole speakers, produce a nearly-ideal controlled dispersion radiation pattern. They send very little sound to the sides, thereby minimizing side-wall reflections whose short arrival times tend to interfere with the perception of the direct sound. Their strong rear radiation produces a generous amount of natural, ambience-enriching later-arriving sonic information. Expression ESL 13A features a dipolar 13x44-inch electrostatic transducer with a radiating area of 572 square inches per side.
• New Ultra-Rigid AirFrame Blade Design, found throughout the Masterpiece Series, is precision manufactured from an aerospace-grade extruded aluminum alloy. The bold, forward-moving styling of this AirFrame Blade rail system, narrow and strong in front, broad and forceful from the side, is a modern design statement. It never obstructs playable surface area or interferes with the panel's dipole sound radiation pattern. It also provides electrical and acoustical isolation, minimizing intermodulation distortion caused by vibration and resonance. The flowing lines emphasize the groundbreaking integration of the panel itself with the compact woofer and amplifier section. The breathtaking AirFrame Blade design enhances imaging, low-level sonic detail, accuracy, and speaker efficiency.
• New PoweredForce Forward Bass Technology combines two MartinLogan audio innovations: PoweredForce, which allows small enclosures to accurately produce massive amounts of bass, and ForceForward, which significantly reduces performance-robbing front-wall bass reflections. PoweredForce Forward bass technology uses an advanced crossover topology with phase timed woofers to minimize destructive reflected energy. By virtually eliminating front-wall bass reflections and working in tandem with the panel, PoweredForce Foward Bass Technology gives you more placement flexibility, and enhances the true audio realism of your sound source.
• New Anthem Room Correction (ARC) is an exclusive technology used to achieve an extremely accurate low-frequency performance in any room. When you engage the ARC software, a specially calibrated microphone (sold separately) measures the woofer output within your listening space and compares it an optimal response curve. The advanced algorithms of ARC then utilize the speaker's 24-bit DSP to adjust your speaker's low-frequency output to account for the unique sonic characteristics of your room. ARC calibration is optional and can be easily defeated using a switch on the speaker.
• New Dual Class-D Amplification with a 24-Bit Vojtko Digital Signal Processing (DSP) Engine produces clean, powerful bass more efficiently than ever before. This combination of technologies enables the effortless delivery of exhilarating dynamic impact with plenty of overhead. Superior, reliable Class-D technology means there's virtually no energy lost between the amplifiers and the woofers. Expression ESL 13A features dual 300-watt amplifiers. Impression ESL 11A features dual 275-watt amplifiers.
• Bass and Mid-Bass Level Controls - even with the myriad benefits brought to play through the impressive woofer system technologies, personal taste still determines the final measure of audio experience. For the final tweak, a bass level knob (±10dB under 75Hz) and mid-bass level switch (-2dB, 0, +2dB) offer fine-tuning of the speakers voicing to account for personal preference.
• Precision-Built Advanced-Topology Vojtko Crossovers are fully hand-built using only the finest polypropylene capacitors and air-core coils. The crossover employs MartinLogan's proprietary Vojtko topology for vanishingly low distortion and seamless woofer/ESL integration. This precision-tuned network preserves the most microscopic sonic nuances while handling the full dynamics of any source.
• Premium WBT Binding Posts are used to connect your electronics safely and securely. Their fine silver filigree is highly conductive and free from "eddy current" effects. These posts are fully insulated for shock protection and topped with an impressive palladium-plated metal cap, with plenty of room for large-gauge speaker connections.
