I don’t know.
230 kilolights/hour is above the speed limit.
Do they have those big subwoofers that shake everyones windows?
The sub woofers are included in the package - the are the same ones used by Disaster Area (the loudest rock band in the Galaxy, but in fact the loudest noise of any kind at all) before they all suffered a debilitating loss of coordination making it impossible to carry on so they put everything up for sale.
In case you are not aware, the ex-Disaster Area sub woofers in question will be located just outside of Mercury’s orbit; when they fire up you will still need very big earplugs.
231 kilolights/hour to be exact. There is no speed limit between the stars. Even super-lifters can’t keep up.
