The Q will not equal with the Brahma... not ever. This is because its a different sub. I have heard the brahma and own the Q. In SPL the Q will win. Its loud and sounded good at it. The Brahma is a different sub with the XBL^2 motor. Some may like on how the Brahma sound but some may not. I personally like the Brahma on the lows and accuracy but the Q has better highs.
