Paradigm E3 LCR v2
Overview
The Paradigm E3 LCR v2 in-wall speaker represents the pinnacle of integrated audio technology. Designed to deliver exceptional sound quality while blending discreetly into your interior, this versatile speaker pushes the boundaries of what is possible with an in-wall system.
A technical feat in the service of sound
The E3 LCR v2 is a concentration of advanced audio technologies. Its three-driver architecture and two passive radiators provide remarkable sound richness. The 2.5 cm AL-MAC tweeter, made from an aluminum, magnesium, and ceramic alloy, delivers crystal-clear highs. Its design incorporates a perforated phase-aligning lens (PPA) and edge diffraction reduction (RED) technology, ensuring optimal sound dispersion and precise sound imaging.
The two 13.9 cm mid/bass drivers use AL-MAG aluminum-magnesium cones, combining lightness and rigidity. Their overmolded suspension (ART) reduces distortion, while the 38 mm high-temperature voice coils ensure impressive power handling. The two passive radiators, also made of AL-MAG, extend the low-frequency response, compensating for the constraints of in-wall mounting.
Innovations that make a difference
Paradigm has developed several proprietary technologies to optimize the performance of the E3 LCR v2. The advanced SHOCK-MOUNT system mechanically isolates the drivers from the baffle, reducing vibration transmission to the wall structure. This innovation contributes to purer and more precise sound reproduction.
The machined aluminum baffle adds extra rigidity to the assembly, limiting unwanted resonances. The ultra-rigid cast aluminum speaker frames have been optimized through finite element analysis to provide stable support for the moving components.
High-level acoustic performance
The E3 LCR v2 delivers impressive performance for an in-wall speaker. Its frequency response ranges from 93 Hz to 22 kHz (±3 dB) on-axis and remains remarkably linear up to 30° off-axis. This feature ensures uniform sound coverage throughout the listening area.
With a sensitivity of 92 dB in-room (89 dB in anechoic conditions), this speaker offers high efficiency, allowing comfortable sound levels even with moderately powered amplifiers. Its ability to reach down to 57 Hz in the low frequencies is notable for a speaker of this size, providing a solid foundation for music and cinematic reproduction.
Unmatched versatility
One of the major strengths of the E3 LCR v2 lies in its versatility. Designed to excel in various configurations, this speaker can be used as a center channel, left or right main speaker, or even as a surround speaker in an advanced home theater system. This flexibility allows for the creation of a coherent and high-performance audio system using the same speaker model for all channels.
The 3rd-order electro-acoustic crossover, with a cutoff frequency at 2.3 kHz, ensures a seamless transition between the different drivers. This design contributes to overall sound coherence, essential for accurate reproduction of voices and sound effects in home theater applications.

Frequently Asked Questions
Can I use the E3 LCR v2 as the sole center speaker in my home theater system?
Absolutely. The E3 LCR v2 is particularly well-suited as a center speaker thanks to its design optimized for voice reproduction and its wide horizontal dispersion. Its power and clarity make it an ideal choice for anchoring dialogue and central effects in home theater setups.
How does the E3 LCR v2 perform in the bass frequencies compared to a traditional speaker?
Thanks to its passive radiators and optimized design, the E3 LCR v2 delivers surprising low-frequency response for an in-wall speaker. However, for optimal reproduction of the lowest frequencies, especially in a home theater context, adding a subwoofer is still recommended.
Is the shock-mount system really effective in reducing vibrations transmitted to the wall?
Paradigm’s advanced shock-mount system is the result of many years of research and development. It is particularly effective at isolating speaker vibrations, significantly reducing their transmission to the wall structure. This results in a noticeable improvement in sound clarity and a reduction in unwanted coloration.
