Though this has been discussed in a previous thread, there seems to have been much discussion without clear recommendations.
The options seem to be:
2 cu.ft. sealed enclosure,
2 cu.ft. sealed enclosure w/ EQ (6dB @ 30 Hz?),
4 cu.ft. sealed enclosure,
4 cu.ft. tuned enclosure.

While the first three options are clear, the question is: what port size should be used to tune the 1500 Sub to a 4 cu. ft. box for a sub woofer application?

Though I feel the 4 cu.ft. tuned enclosure will be my choice, I'd be curious to hear opinions about these four options.

Thanks for your opinions and clarifications on this.
