I have wrestled with sub integration for years, until I purchased a DBX Venue 360. You can control your main speaker delay or sub delay. This unit is designed for live stage performance, but cured my subwoofer problem completely. You should really look at the specs and try one. It fixed my TT acoustic feedback, as well a a whole host of issues. I used to listen and worry about how I could make everything coherent. Now, I just listen and appreciate.
Subwoofers and Phase Question For You Sub Experts
I use a pair of Dunlavy SC-3 speakers, known for their time/phase coherent crossover design.
When the stars align the speakers completely disappear and there’s a sense of space and 3 dimensionality that I’ve heard from few other speakers/systems. It’s easy to destroy the illusion with things like poor placement, poor setup of room treatments, etc.
Adding subs to the setup is both a blessing and a curse. The Dunlavy’s need some support in the nether regions and a pair of HSU subs do add a solid foundation to music which enhances the overall presentation; however, it’s at the expense of some stage depth, width and image dimensionality. Placing the subs a few inches forward of the front plane of the speakers helps a little but that isn’t where they perform at their best as ‘subwoofers’.
Finding optimal room positions for bass augmentation always creates a clash with the phase aspect of integration resulting in the diminished soundstage described above.
Playing with phase settings has little impact on the problem since there’s just a toggle for 0 and 180.
Which brings me to the questions -
1/ How does running a swarm setup, with 4 subs, affect phase/time integration with the mains? Does it create twice or half the issue or remove it altogether?
2/ Looking at subs such as the JL Audio F series with auto room calibration, does the EQ algorithm compensate for any time/phase anomaly or is it simply looking for a more linear bass response?
I don’t mind investing in more sophisticated subs so long as I don’t end up with the same problem. I’m not really inclined to mess with software and the like, unless there’s no other way.
Thanks
