Bite can be called sibilants or etched ,bright , in natural if it’s a horn it should sound brassy ,a screech from a electric guitar and if using reverb can be electronic sounding , .having been modding or upgrading Loudspeaker Xovers for Many years. If you have say a bright beryllium tweeter, or horn , more times then not.
over80% of all loudspeakers use substandard parts for example I use mod Xovers and make loudspeaker purifiers ,
in your speakers a $2 ceramic resistor which can be gritty I use the best Mundorf copper foil ultra , or Path audio resistors $30 each, capacitors many use ok at best Solen capacitors , or cheaper line clarity caps ,or Mundorfs mid line. Why
it’s all about $$ . Roughly $25% of the cost of-your speaker including packing is all that goes into your speaker ,the rest R&D overhead and markup.
i was a audio dealer for 10 years, this too includes the vast majority of electronics .
this is why many times I just buy a quality component then lookfor all weaknesses and upgrade it ,with electronics for example I take Duelunds world class capacitors on the coupling or output stage of my preamp section from the very respectable Rel cap and give them a Loong burn in and a huge jump in performance
