I am about to force myself to build or buy a new bass cab (Selling current setup). I really want to build a small lower watt single speaker cab that will be well rounded for 4 and 5 string basses. I will at first anyway be running it off my Bugera V22 guitar amp. It is a 20 watt all tube amp. I have been leaning towards an 8" but wanted to know if you think it will fall short or not? This will not be built for gigging or anything like that. Bedroom only and hopefully like it enough to mic it for recording. I know most 8's want go very low but I am not needing earth shaking bass but does anyone know if I do build my own cab and if I added one of those bass radiators to it (this is a motor-less speaker) and helps move air. Would this help or hurt sound quality? Give me your thoughts. Trying to clean up my setup to hopefully have one rig for guitar and bass. I can even run 2 cabs off this amp and thought about doing that as the 12" guitar speaker sounds nice with my bass but as you can expect has no real bass coming from it.
