And it is not that you can do it but it is a very common practice. Some manufacturers offer actuators of sometime tapping pads. I think even the largest Wilsons offer a set of series resistors for crossovers to attenuate HF. It is very common practice to cover the ports for ported design to get more proper response for given speaker for a given room. Some manufacturers even offer along with the speakers special inserts made for the ports. I have old and ugly Altec 19 home that has tweeter and MF attenuator – stupidly done but nevertheless… And of course any person who has ears and do not care too much about the shiny glossy surface of the speakers would do to them whatever s/he want in order to get from them the sound that s/he wants. The hole point is that with a single-driver speakers there is no options besides to boil them for 30 minutes in sulfuric acid. |
