Do I need a sub woofer to match my ATC SCM11s


Hi,
I love my speakers (ATC SCM 11s), but am wondering if adding a sub woofer would better my experience? The speakers are on stands being driven by a Hegel H160. Any suggestions/tips to further enhance my system would be greatly appreciated.

why can't there be a right answer?  all joking aside, that's my fear with the sub: I'll never get it right and I will just add another piece that won't provide that ultimate solution that I seek. I don't want to find myself further invested in this current setup and unsatisfied.
Hi Itzhak1969, that's my fear exactly. I am using my stock power cable and I'm currently arranging to have it upgraded. how much of a difference can that make?
My limited audition with passive ATC home monitors (SCM 19s?) at last year’s Capital Audio Fest also left me with the initial impression of sounding "thin" in comparison to other similar rooms there. It left me wanting another audition to get my arms around those particular speakers better in that they appear to be of very high quality in terms of construction and design. It’s one of those audio mysteries to me at present that my curiosity won’t let go.
Upmarket power chords can make huge difference also interconnects and speaker cables but you have to match them carefully to your system ,if it doesn't help and you feel that your speakers are not good enough in low frequencies it's better to upgrade to floorstanders than adding a sub to your system, I in general not a big fan of standmount speakers they can be very good at transparency, image and clarity but lack in dynamics and low frequencies.
jeres8860,

     If you like your ATC mains and have the space in your room, I think I have a good solution for you.
     It's called a distributed bass array system and it provides state of the art bass response in virtually any room and integrates seamlessly with any speakers.  It basically consists of 4 subs strategically placed in the room  that delivers exceptionally good bass throughout the entire room, not just at a designated 'sweet spot.  
     These dba systems can be purchased as complete kits (4 rather small 2.5'h x2'w x1'd unamplified subs with a 1K watt amp with equalizer and crossover) such as the Audio Kinesis Swarm and DEBRA systems for about $3K or you can build your own custom dba using your choice of subs.  Here's a link to a review of the Swarm system by The Absolute Sound:

     I have large Magnepan panel loudspeakers which are notoriously difficult speakers to integrate with subs.  I bought the Audio Kinesis DEBRA complete kit( almost identical to the Swarm) a few years ago and I'm thrilled with it.  It's given my system seamlessly integrated bass down to 20 Hz +/- 3dB that's capable of reproducing accurate, natural and life-like bass whether the bass content is deep and powerful or fast and taut.

    I'm almost certain a dba would work equally well with your speakers and room. Audio Kinesis also offers a 30-Day in-home trial period .on the Swarm and DEBRA.
     I have no connections of any kind with Audio Kinesis, I'm just a very satisfied customer.
Good luck, 
Tim
