jwgorman Posted April 1, 2018 Share Posted April 1, 2018 So I’m thinking about purchasing a pair of Faital Pro 15PR400 4 ohm woofers for science. Anyone out already tried this? http://www.faitalpro.com/en/products/LF_Loudspeakers/product_details/index.php?id=101060101 Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 3, 2018 Share Posted April 3, 2018 A cruise through the T-S parameters makes it look like a good candidate. Have you modelled it in an enclosure calculator? Quote Link to comment Share on other sites More sharing options...
jwgorman Posted April 4, 2018 Author Share Posted April 4, 2018 John, I did use an online box calculator to determine that the Cornwall box had roughly enough volume for an f3 in the low 40s. I think I entered a param incorrectly. Quote Link to comment Share on other sites More sharing options...
pzannucci Posted April 4, 2018 Share Posted April 4, 2018 How much different is the port interaction using a K-33 vs this woofer? Quote Link to comment Share on other sites More sharing options...
jwgorman Posted April 5, 2018 Author Share Posted April 5, 2018 I’m not sure how to answer that. Quote Link to comment Share on other sites More sharing options...
pzannucci Posted April 5, 2018 Share Posted April 5, 2018 If you are modeling or just figuring out box tuning, if the Faital models the similar to the K-33 then it sounds like you would have similar tuning results. You can always (if the port needs to be smaller or longer), use a peace of ply or mdf across the bottom or the slot top board to modify the tuning some. Should be pretty easy and will get you in the target response modeled or by ear (spl meter). Quote Link to comment Share on other sites More sharing options...
jwgorman Posted April 5, 2018 Author Share Posted April 5, 2018 Ah, gotcha. Quote Link to comment Share on other sites More sharing options...
