Not with input power of 1200 watts. Anything smaller would produce port compression and port noise. If you went with a 6 inch diameter port ( or 3 inch by 9.5 inch rectangular ) 33.5 inches long you would be limited to 700 watts input. Above that, compression and port noise would be an issue.Is it possible to get the same results with 2 smaller and shorter ports? Thanks for your help!
