@audiokinesis Hi Duke! Always great to read and learn from your postings!
I am also interested in your satellite speaker. Where does it crossover?
@jeffseight I have been thoroughly enjoying my DBA from Audiokinesis in 5 different rooms (the smallest and first listening room was 9’ x 11’ minus closets) varying in size, shape, furnishings, and floorings.
I have tried many subwoofers but nothing worked in the tiny room. I gave up trying until hearing about the DBA concept. After doing my research, decided to try. Duke was very upfront and honest when he said that is the smallest room so far in his experience. No guarantees
The DBA worked out very well for me in the tiny room, with my system.
It is not necessary to have "matching" subwoofers.
I have not tried mixing in active subwoofers but many here have tried with great results.
I have tried mixing in/adding additional passive subwoofers. Each additional subwoofer brings a significant improvement until around the 4th or 5th one. Perhaps around 7 in a really big room.
Good news is you can start small. Just grab a decent subwoofer amplifier and a few subwoofers.
After moving twice, I am now enjoying my DBA in the 5th room since using it.
I found my DBA solution.
Hope you find yours!
