You spend $50,000 on a set of speakers but they don't really sound their best until you spend another $5000 on a pair of Townsend Platforms? How much of our hobby is science and how much is just Kool Aid? Fair to say in this hobby, you'll never go thirsty. 🤣
The JBL Project K2-S9500 Introduced in 1989 cost $30000, a pair new and came with concrete platforms. I guess it depends on what speakers you buy and the manufacturer! See here.
