When Benchmark decided to add a speaker to our line, the goal was simple in concept, but would require careful implementation. We would build on the attributes of our favorite speakers. Then take the art and engineering a step further. We needed to combine enjoyable voicing, great imaging, powerful dynamics, and solid bass response in ONE new speaker, a speaker we would want to own and use in our own homes. A speaker YOU would want to own.



1. Listen first. We asked: What characteristics do great sounding speakers share? We spent hundreds of hours listening to dozens of models from top-tier manufacturers. There are some very good speakers out there. The best reproduce music in an engaging and organic way. We picked our favorites.
2. Using state of the art measurement equipment, we analyzed the response curves and electrical characteristics of the best sounding speakers in our large test group. 
3. Our engineers identified important design elements of the best speakers. We purchased exclusive rights to essential technologies, identified and sourced critical components. We drew on the many lessons learned from three decades of collaboration with major recording and broadcast studios. Finally, we applied our considerable expertise in tight tolerance component matching, PCB design, precision assembly, and stringent quality control. 

The new SMS1 represents both the art and science of sound. Great design, strong engineering, quality components, in a speaker that conveys the magic of the music.


The return to acoustic suspension:

We know that ported loudspeakers have become fashionable. We don’t do fashion. Ported speakers create the illusion of bass extension by emphasizing certain frequencies (hence the name tuned port). This often results in non-linear bass response sometimes described as “one note bass”. The technique can sometimes make a small speaker seem large. But, accuracy can suffer in the name of big bass. The SMS1 is an acoustic suspension loudspeaker. By nature, it is more linear. It can also produce impressively deep bass. The trade-off is efficiency. The SMS is not recommended for low power single-ended tube amplifiers. They work great with larger tube amplifiers (30 watts or more), and with quality hybrid and solid-state amps. If you have a small listening room you may have good results with a small amplifier but we emphasize that deep solid bass usually requires a robust amp. Which brings us to the Benchmark AHB2. Though the SMS1 will sound great with any high quality amplifier, it mates wonderfully well with the Benchmark AHB2 amplifier.

Quality components:

We are proud to use superior quality components in this design. Our exceptional woofer and soft-dome tweeter were chosen from many possible types. These transducers were selected for both great sound, and low unit-to-unit variance. Our crossover uses custom film capacitors from Clarity Cap - some of the finest available. All inductors are custom wound air core, to minimize distortion. Our stainless mesh grills are fabricated from the same material used for fine microphones, nearly transparent acoustically, and more durable than grill cloth. Together, these components contribute to a speaker with outstanding clarity and imaging - a clear window into the music you love.
