(2) Usher 8955a in 60 liters...?
Im building a 3-way speaker that has 60 liters of available volume for a pair of Usher 8955a drivers. They will be playing about 350hz and down, sharing the airspace. Would it be better to (and why)...
1: Go vented with a smaller airspace, and tune 60L, 30hz 2: Go sealed with a 60L airspace, Qtc 0.61 3: Go sealed with a 40L airspace (add mass), Qtc 0.71 Thanks |

Usher 8955A looks like it will enjoy a large vented cabinet. More like 50 Litres per driver.
Download Unibox, or Jeff B's Woofer box sim, and decide what you think is best.
