I build a lot of Guitar Cabinets, but i never build a bass cabinet. I like to build a small 1x10 bass cabinet for homepractice with a Warwick Gnome. The Speaker should be a Jensen BassPunch BP 10/150. I never worked with WinISD. So im not sure if my Calculation is rigth. Speaker Data: FS: 55Hz QTS: 0,33 QMS: 5,93 QES: 0,35 RE: 6,1 ohm VAS: 42,6 Liter My Calculation with WinISD for an Vented Box says Boxvolume 20,55 Liter and and two Vents with Vent Diameter 1,97 inch and 6 ich Vent length. Maybe someone could tell me, if this is correct? I dont nedd a perfect result. I d like to have fun while the builiding and playing bass in my livingroom.
