Hi friends, I haven't been around for a while, and i guess im just passing by for now. I hope everyone is doing okay.
I have a question regarding subwoofer EQ. I don't have one at the moment, and i know it's beneficial, but my question is, isn't the off axis response a lot worse with an equalised sub? If so, doesn't that outweigh the benefits of a flat sweet spot freq. response using EQ?

If i should consider one, is the BFD still the best cheap option or should i look at other options?
