INTRODUCTION: WHAT IS A HIGH END IN-WALL?

The new Snell AMC series units bring a novel approach to the design and construction of in-wall loudspeakers, expanding the boundaries of in-wall performance.

Our primary goal was to develop loudspeakers that delivered performance that was as close as possible to that of our highly regarded freestanding loudspeakers, like the K7 and LCR7. To do this several issues had to be addressed.

The bass performance of conventional loudspeakers mounted in wall cavities is very unpredict- able. Cavity volume can be large, which should be good for bass performance. However, with one very short dimension (approximately 4”) and one very long dimension (up to 8’), the wall cavity takes on the characteristics of a closed-end organ pipe. This creates a strong resonance that tends to null out the bass. Lining this cavity with fiberglass will reduce the “Q” of the notch but not restore the bass. What is needed is a defined volume of a more regular size. This is best done with fully enclosed in-wall speakers.

The Snell AMC loudspeaker enclosure is a thin, but strong, aluminum tub. It is both damped and braced. This largely contains the back radiated sound of the woofer within the enclosure. An added benefit of containing the woofer output is a reduced chance that resonances will be excited in the house walls. Furthermore, sound “bleed through” to adjacent rooms is reduced.

To minimize resonances in the Snell enclosure, the speaker baffle uses a technique first pioneered on our .5 and XA series loudspeakers. The baffle is a three part composite with MDF (fiberboard) outer layers around a thin, but highly effective, damping layer. This controls the panel resonances of the baffle that can obscure midrange clarity. As we have found with our freestanding loudspeakers, a better loudspeaker cabinet means a better sounding loudspeaker.

In addition to these unique solutions, all traditional Snell attributes are retained. Highly coher- ent in-phase crossover networks ensure a seamless blend from driver to driver. Drivers are designed for smooth, wide range response and low distortion. Long sessions of listening and adjusting give each system that special, characteristic Snell sound. Finally, that Snell sound is guaranteed in every production pair by Snell’s proprietary 0.5dB production tuning techniques.

730 770 830 870 specifications

Snell Acoustics is renowned for its commitment to high-fidelity sound reproduction, and its series of loudspeakers, including the 730, 770, 830, and 870 models, exemplify this dedication. These models reflect the brand's ethos of crafting speakers that deliver an immersive audio experience, suitable for both home theater enthusiasts and audiophiles alike.

The Snell 730 is designed as an entry-level model, making it accessible while still delivering impressive sound quality. It features a 6.5-inch woofer that provides deep, rich bass response, complemented by a 1-inch silk dome tweeter that ensures clear and precise high frequencies. This model is well-suited for smaller spaces, easily blending into any room decor while still making a significant sonic impact.

Moving up the range, the Snell 770 offers enhanced performance with an improved driver configuration. It includes a larger 8-inch woofer for extended low-frequency reproduction, allowing for a fuller, more dynamic soundstage. The 770 also utilizes advanced cabinet construction techniques aimed at minimizing resonance, thus preserving audio clarity.

The Snell 830 represents a significant leap in technology and performance. This model is equipped with dual woofers, each measuring 8 inches, which work in tandem to achieve higher output levels without sacrificing accuracy. The 830’s sophisticated crossover network ensures optimal driver integration, resulting in a seamless blend of frequencies that captivates listeners. The use of high-quality materials in both drivers and cabinet design helps reduce interference and distortion.

At the top of the range, the Snell 870 stands as a flagship model that embodies the pinnacle of Snell Acoustics' engineering prowess. Featuring a three-way design, the 870 has a dedicated midrange driver that enhances vocal reproduction and allows for an expansive soundstage. The implementation of advanced phase coherence technologies leads to detailed imaging and dynamic range, making it a favorite among serious audiophiles. Additionally, the robust cabinet construction minimizes unwanted resonances, further improving sound quality.

Across the Snell 730, 770, 830, and 870 models, audiophiles will appreciate the brand's attention to detail, from driver selection to crossover design and cabinet engineering. Each model is crafted to deliver an authentic and engaging listening experience, making them worthy contenders in the realm of high-performance audio. Whether for music or home theater applications, these speakers stand out for their reliability, clarity, and overall sonic excellence.
