I wanted to start a thread devoted to cabinets and speakers. Seems like a very important topic for DIY amps. I will be starting to build my own soon. I see a lot more discussion about tubes, capacitors, etc. I expect to learn a lot from the discussion. My first venture will probably be a poplar cabinet for a Princeton. That amp will take the place of a Blues Junior III that I currently use. The BJ will be getting some mods once it comes off line. After those are done I plan to build a pine cabinet for it. I have a Princeton that is in a MDF cabinet. So I will be able to do some side-by-side comparisons. I don't intend for this to be about my cabinets in particular. So if you have some that you built or have done comparisons, please post them. Don't get the idea that my part of this will happen at lightning speed. I hope to get the Princeton cab done by the end of the year. I am starting this now so that I can learn from the experiences you share. It will help me get a better results and factor in comparisons that might be of interest along the way. Much appreciation to those that share their knowledge and experiences. Most of the discussion on the forum is friendly and informative. Hope this thread can provide some worthwhile exploration of an important aspect of amp building.
