^That's the response of the relatively new Silver 8, not the much older Silver S8.
My post talked about the much older Silver S8.
(The Monitor Audio Silver names can be confusing. The Silver S series preceded the Silver RS series, then came the RX series, then the Silver 1,2,6,8,10 series, and now the Silver 50, 100, 200, 300, 500 series, which I think is sometimes called the Silver 6G series for sixth generation.)
The Silver 8 fixes many of the issues found in the Silver S8 (better tweeter power handling, smaller dedicated midrange has better directivity match to tweeter, metal cone resonances better suppressed, bass resonances reduced).
