I have designed many speaker cabinets over the years. A lot of my designs are for high end home audio speakers. With these designs, I want no resonance, just liner low distortion sound. I worked on many different guitar cabinet styles. I used Baltic Birch, MDF, different types of plywood and plain old clear pine boards, open back and closed back. I have quite a few Fender amps and I have had only 2 Marshall's. My new cabinet design was for my 2007 Marshall JVM 410H. I was wondering one day how would my Marshall sound using clean green, which is very clean like a Fender Twin. I have 2 10 inch Weber 80 watt California's, which are like JBL D120's. JBL D120's are suppose to be the ultimate match for the Fender Clean sound. I decided to build a new cabinet to match my JVM 410H. The cabinet measures 29 1/4 wide, by 11 1/2 deep and 20 inches tall. It has a partially open back with a 5 inch opening. After a few weekends of assembling the cabinet, routing, covering piping and grill/ baffle it came together. The speakers are wired in Series for 16 ohms. I do find Marshalls do seem to react better at 16 ohms in my opinion. So I started with the Clean Green channel and to my hoping surprise, it sounded fabulous. Rich, deep and smooth. Also it is equally fabulous on the crunch and over drive channels. I have an amp combo that goes from Beatles to Black Sabbath. Also it's not real heavy. The low end response is very chunky and I feel exceeds my 4X12. Please feel free to comment or post questions on cabinet making, thanks for reading!
I tried to post some pictures, I guess the files are too large.
