Took the plunge on a S10 to compliment a pair of 4S monitors in a desktop setup. When I was thinking about the 4S' I thought they would be lacking bottom end and I would eventually need to add a sub. But, after they arrived I was satisfied with their low end performance and decided that maybe I didn't need the sub. This was way before the S10 was released. In the mean time I added a set of isoACOUSTIC stands to get them off the desktop and that made a surprising difference in making the big soundstage into a HUGE soundstage. Before that, I had them elevated on some foam isolating pads. The difference was similar to the difference between a photo that is slightly out of focus to another that is in perfect focus. The out of focus version might look great until it is compared with the in perfect focus version. The stands also tightened up the bass and lower midrange. I was a happy listener, Then I saw the announcement about new subs and thought maybe it was time.
I really doubted the sub would change much since lots of popular music has little or no content below about 40 Hz. I do listen to some stuff by David Helpling and David Arkenstone as well as a bit of classical, jazz and rock. Maybe I would hear some difference on organ and synth.
I was wrong. After plugging in the S10 and making some minor adjustments - set up is pretty easy - I wasn't prepared for some of the stunning differences that missing bottom octave makes!
The soundstage grew even wider and deeper. Individual vocalists and instruments became more three dimensional. The 4S' alone, were really good at disappearing and throwing a deep and wide soundstage. But, the sub seemed to fill out things in a way that took the system to an even higher level. It is very easy to "hear" the venue on recordings made in halls using binaural or other high quality techniques, for example.
Then I played some files I knew had info below 40 Hz and I was bowled over by the tight clean way the S10 seamlessly presented low synth lines. A great example is David Helpling's "Worlds" track on his
Between Green and Blue release. The low synth shows up about 30 seconds into the track and my jaw hit the desk! I had listened to the track dozens of times before and wasn't prepared for the difference a good sub would make.
On Dire Straits' "On Every Street"
Iron Hand track there is some lower synth that accents a few moments. I have never heard those synth lines sound quite so good!
In an article I read years ago, the author argued that a sub added substantial realism to soundstage reproduction since many venues have low frequency information in the ambience. I think that the way the S10 seems to add depth, width and more three dimension convinces me the author was right. All in all, I am a happy Emotiva customer made even happier. Can you tell?
