Subwoofers vs. Studio Subwoofers : r/audioengineering - Reddit

WebWell the biggest difference is that Studio Subwoofers usually have a foot pedal switch to turn them on/off. This is helpful as most of the time you want the sub off but will frequently turn it on briefly for a listen through. They are also often more flexibility inputs and outputs than say a home theater sub. Web5 Aug 2024 · The SUBOFF model without appendages was applied to conduct the simulations, and the Reynolds number based on the free-stream velocity and the length of the body is R e L = 1.2 × 10 6.
