The frequency response is one aspect of an Aurotone-type monitor. Typcally they should have a mid boost, however, simply placing a HP/LP filter on your own monitors will not turn them into Auratone souandalikes. Their main attribute is their time domain domain response, as a result of being sealed boxes, something you don’t find very often these days. Percussion spikes, effects tails etc. should be crystal clear.
Think of them as a mini pair of NS10s. If you get on well with NS10s, you’ll probably appreciate Aurotones and their clones.
