Hello DB,
Okay, I understand.
If you like the looks and sound of a HGS-10 aside each KEF Ref 1, I'd suggest you try positioning your two HGS-15s in the following manner:
Leave both of your 10s exactly where they are aside each main speaker. You already know these sub positions result in very good integration with your main speakers which is virtually the same as utilizing the crawl method to locate them. I suggest you just consider their current positions are the optimum positions for your sub#1 and sub#2 in the 4-sub distributed bass array (DBA) system you're creating and just proceed to optimally locate your two 15s, as sub#3 and sub#4, in your room.
To do this, just do the following:
1. Hook up one of your 15s and place it at your listening position.
2. Play some of your jazz with good repetitive bass through the 15 and your two 10s.
3. Use the crawl method, starting at the left side of sub#2 (located aside your left channel main speaker) and continue walking counter-clockwise around the perimeter of your room until you determine the exact spot that the bass sounds best to you (best integrated and the most natural).
4. Position sub#3 at this exact spot.
5. Hook up your other 15,place it at your listening position and repeat steps #2-4 to optimally locate it.
6. Once completed, sit at your listening position, play the same music with all four subs playing and verify that the bass sounds seamlessly integrated and natural. Note: You will likely need to precisely adjust the Volume and Cutoff Frequency controls on both 15 subs until you determine the overall bass performance has been optimized at your listening position. It's best if you recruit a volunteer for assistance on this step.
If you follow this procedure precisely in relocating your pair of HGS-15s, I believe you'll notice a few things.
First, you may be surprised at the locations that the two 15 subs actually wind up positioned at in your room when optimized for bass sound quality. However, I can't predict even generally where they'll each be positioned in your room since it depends on the subs used, your ears/brain and your room qualities (dimensions, wall/ceiling/floor materials, furnishings and any room treatments present). I just suggest you follow the procedures strictly and make sure you pay close attention to bass quality when locating them.
Secondly, I'm almost certain you'll prefer the overall sound quality using all four of your subs when compared to using just the pair of HGS-10 subs. Remember, I'm speaking from experience using not only a pair of subs but a 4-sub DBA as well. You'll notice the bass is even smoother, more detailed and with the realistic bass power, impact and dynamics that are usually only heard and felt when you're present listening to music played live.
But don't worry, the high quality bass is always there but the volume control still allows you to choose the overall volume level for playback.
Enjoy,
Tim
