As former Bass List member, I purchased four of original Shiva from first production. Does anyone one have the TS parameters for these? I'm assuming there have been some improvements over the years. -Btw, I used my four in 2' diameter X 6' sonotubes tuned to 15.5hz if memory serves. Preparing to pull them out for low-q acoustic suspension experiment. I ran across a nice paper possibly by Dan Wiggins? Maybe my vintage Shivas can be substituted? Thinking about building two subs with two Shiva each with q~0.5. TIA!
Rummaged around and found these two Shiva White Papers with different specs, so suggest you average the three sets to use if not willing to measure all yours.
Got the .pdf files to open! Switched to Edge on my Galaxy s22. Chrome on s22 wouldn't open them. Thanks again!
