JM Labs recommends setting the subwoofer crossover as high as 120Hz, however the crossover does not indicate a 120Hz position, so I turned the setting slightly above the 12 o'clock setting.

The Cub is certainly placement sensitive and seemed to produce the most accurate bass about five inches away from the front wall and 14 inches away from the corner of the room.

Although the Sibs do not accept banana plugs, they are a simple and quality termination alternative and can easily accept a larger wire, up to about 12 gauge.

Final Take - I wasn't sure what to expect from the Sib & Cub performance. Though I have always held Focal/JM Lab in the highest regard, I questioned the application of a concave front baffle for satellite speakers.

Right out of the box, the Sibs put my doubts to rest with excellent imaging and staging. Using a DVD-Audio sampler disc, I put the system through its paces and yielded impressive results.

The top end of the Sib satellite is quite remarkable on its own. My favorite DVD-Audio disc used to review speakers is that of ADC Records, 96/24/5.1 Studios, AIX All Stars. In the Surrounded by Christmas tracks of the media, you will find top-end recordings I argue probably don't exist anywhere else in the world. There are very few speakers that can capture the dynamics of the cymbals recorded on this disc. I am still shocked to note that this entry level JM Lab ensemble is one of them.

I found myself trying to pry the grille off so I could find out just what driver JM was using for the top end--no luck. I am left to believe that the concave configuration of the front baffle leaves the midrange in such a way that it does not mask the top end and actually isolates the tweeter as a result.

The Sib & Cub is a remarkably revealing speaker system and this may leave you disappointed, as many recordings today will not live up to the capability of this tiny ensemble.

For movies, the Cub becomes a growling, rumbling bear with an incredible output on the bottom end that ultimately makes for a very well balanced attack during cinema playback. The details were plenty and accurate with a solid bottom end. Occasionally I detected a somewhat nasal sound to voices. This seemed consistent with the media itself.

This is the first home speaker ensemble Ihave reviewed from JM Labs and the experience has been quite positive. Even more so, I learned that JM Labs places its audiophile heritage ahead of its price points. That scores big points with me.

I recommend giving the Sib & Cub speaker ensemble a listen if you're auditioning speakers in the under $1,500 category and looking for something compact at the same time.
