Vandersteen Sub woofers v Rythmik Subs

I know that Richard V. recommends corner placement of the 2wq's and I have had one room that corner placement worked well in. However in my current listening room (and the previous one) the bass is not good in the corners. Every room is different and in my "particular" room there is way to much low frequency reinforcement from the corners. It over loads the room with energy. Again dealing with smaller  (and odd shaped non symmetrical) rooms is challenging. Adding to the challenge is limited placement options for multiple large boxes with wires that need to be routed somehow.  WAF comes into play here (again). The current location inboard of the 3a sig's is the best location that I have come up with so far and sounds quite good for the moment but I'm not done experimenting yet. Those new Sub 3's have my attention though. Will be keeping an eye on them.

It's all a balancing act for sure. In an ideal situation we would all have large rectangular symmetrical rooms with high ceilings, constructed of musically good sounding material (because all rooms and all material have a "sound") That would minimize the problems we encounter. We could even design room acoustic treatment into the room. Again in an ideal situation we would have  purpose designed rooms. But most of us have to live with what we have and make the best of it with our limited resources, including time. For me this is a journey and I am still heading down the road and having fun with it.
 Another thought is from a manufactures point of view. Trying to design speakers that work well in all the wide variety of rooms that their designs will be asked to sound good in must be a daunting challenge.

Have a great day!

Hi sonicjoy,

     Very good post with some good points.
    After over 40 yrs of building systems and listening to music in different homes and rooms, I definitely agree with you that every room is different, especially in bass response. 
    When installing a system,  I've recently come to the conclusion that it's best to view a sound reproduction system as 2 separate systems: a bass system and a mid-range treble/sound stage illusion system.  I think having a separate bass system as 4 subs can actually be more useful for achieving best integration and sound if you have the room space.
    The bass is the hardest to get right because the sound waves are so long that they continue to bounce/reflect off all room barriers until they run out of energy.  These sound waves eventually either crash into each other causing standing waves and typically a lack of bass at those points or they piggy-back on another reflected sound wave and cause bass reinforcement and typically exaggerated or boomy bass at these points.  
     Acoustic engineers are able to predict where sound waves will intersect based on the room dimensions, sound wave frequency, barrier material and speaker/sub location(s).
     The beauty of a properly set up distributed bass  array system of 4 or more subs is its ability to eliminate the vast majority of intersecting bass sound waves, and therefore the vast majority of bass peaks and nulls, in any given room.  This not only makes the bass sound more accurate and smoother, the bass response is this good throughout the majority of the room. 
     As you're all too aware, having a small and non-symmetrical  room only makes good bass response more difficult to attain.  I understand you have space and waf issues but I still believe a Swarm distributed bass array system is your best option for achieving state-of-the-art bass response in your room.  
      This system is not as intrusive as some may initially think.  Each sub weighs about 44 lbs., has a 1 sqft. footprint and is 28 inches tall.  Each sub is positioned with the driver facing, and about 1 inch away from, the wall.  The visible portions of each sub(sides, top and back) are made of your choice of high quality wood and actually look quite good and stylish.   Have your wife choose the wood.
      Hiding the speaker wires may be the most difficult issue if you can't run them below the floor or in the walls.

 Just my thoughts-good luck,
      Tim

@noble100 ,
I think Johnny was referring to the integrated equalizer in the new Sub 3.
As far as I know, there are no subs with equalizers incorporated.

Thanks for the kind words. I bet your system sounds great. Would love to try the swarm out.

So far we seem to mostly focus on trying to solve the bass problems with loudspeakers(subs). However the other way that seems to get less attention is to fix the room.

Lately I have been hanging out at Acoustic Fields web site learning all about room treatment from the owner Dennis Foley. He has a daily youtube channel. Very interesting stuff that may make you rethink some things you think you know about acoustics in listening rooms as well as recording studios. They design room treatment systems for some of the best recording studios and high end listening rooms. But thats a whole new can of worms and a topic for a new thread.

Cheers.

Hi sonicjoy,

     Okay, thanks.  I'll check out the Acoustic Fields website.

     What's great about the Swarm system, when properly set up, is that it requires no room treatments, DSP, equalization,  or room correction mics and software.  It's really kind of magical how eliminating the vast majority of bass standing waves, and the resultant bass peaks and nulls, in the room results in such excellent bass performance throughout the entire room.  I think it's something you have to hear for yourself to really believe.  It sounds too good to be true when just verbally described.  It really took a lot of research and convincing for me to overcome my skepticism and give the distributed bass array system a try.  But I am so grateful I did and now feel like I owe it to other members to spread the word.
     I think this could be considered a type of room treatment because it prevents bass response issues at the root cause, which is likely a lot more effective than trying to compensate or room treat for the inevitable standing waves once they actually exist in the room.  Bass room treatments are typically much larger and less effective than mid-range and treble room treatments in my experience.  
Thanks,
