With an overall SQL setup such as a sealed box or a low tuned ported box, the Brahma will give better results. If you want something that is more SPL oriented but sounds good, then the DD sub will do very well. They are designed to work in ported enclosures and need a relatively high tuning due to the Fs of the driver. They recommend a 45hz tuning frequency for most cases, so if that's not your cup of tea, then look elsewhere.
