I expected bass to be bigger, deeper, and more fleshed out with the LōKē. That it certainly was. What I did not expect was the ability of Wilson’s smallest subwoofer to enhance every aspect of the listening experience—especially the sense of space. As the soundstage grew deeper, wider, and more coherent, as soundstage boundaries became more evident, as air between and around instruments and voices increased and the quality of music reproduction rose to mesmerizing levels, my appreciation for the transformative potential of the LōKē grew exponentially.

Audition the LōKē. Throw all your favorite music at it, and give it a major bass workout. Turn it on and off and on again and discover for yourself what a difference it makes. If your room and speakers are appropriate for its size and power and your budget allows, it’s hard to imagine that you won’t be tempted to invite Thor’s little brother into your system for a long stay. My highest recommendation.

If I’m honest, there was a time when I wouldn’t consider recommending a Klipsch subwoofer to anyone. That time is no more, the RP-1600SW surprised me; it can play very loud without losing composer, has impressive dynamics, it’s almost impossible to trip up this thing. The protection mechanisms are all but bulletproof, you can experiment with impunity. Even at the limit it sounds totally in control, composed despite your best efforts to force it not to be.

Bass was always sharp and distinct, each note and effect clearly defined. There was no overhang, nothing sounded out of place. When it wasn’t necessary to do anything the RP-1600SW didn’t, when it was time to get serious it could and did. The Klipsch Reference Premier line of subwoofers is definitely worth adding to your short list

The laws of physics are immutable, there is perhaps no better example of that then as they relate to subwoofers. When it comes to deep bass played at volume you need several things, chief among them is a large enclosure. The ELAC DS1200 did soften the lowest octave when I pushed the pace, but frankly that’s not the least bit surprising given the aforementioned pesky bit of physics. You can mitigate that to an extent with precision engineering, overbuilt drivers, powerful amplifiers and DSP tuning, all things ELAC includes with the DS1200. But no matter what, at some point you will hit a wall. When the DS1200 finally reigned things in it did so in a graceful and fluid manner, never once tripping over itself regardless of how hard I tried to get it to do that very thing.

I pushed this subwoofer and it did not care in the least, remaining unperturbed throughout. Add to its composure a stylish and unique appearance, along with a well thought-out app that allows for minute configuration and customization, and you get quite a lot with the ELAC DS1200.
