Would like to invite for sharing new ideas/tips with a goal to fine tune methodology for measuring active speakers and producing filters as a result.
Would be nice to stay firm with REW software.
Today most commonly methods to take measurments for active speakers it is directly imported from speaker manufacturers making them with PASSIVE FILTERS. They as a target aiming for all kind living areas. Shortly- massive production.
This process looks like this:
1.Producing drivers for speakers' measurements done in the anechoic chamber.
This is perfectly OK and acceptable unless measurements can be taken for your listening space.
2.Manufactures uses measurements taken in the anechoic chamber and that data it is base for filter production.
This is perfectly OK and acceptable, because speaker it is for mass production and must to cover needs of anyone.
3. Such speakers arriving to customers room. From this moment on it is whole bunch of speakers measuring methodology principles and software tools (like Dirac Live) and other commercial products (sound traps, diffuses and much more such) to match that speaker sound like in the anechoic chamber.
With that I have a problem.
Active speaker system has upper hand technologically to passive filters and are very flexible with FIR and PEQ filters.
When we (DIY) speaker builders are not targeting to massive production market, but most of the time but we trying to build best speakers for drivers/room or just speakers' concept, it makes sense to have solid how-to tutorial step by step guide for building active filters. Most popular is minidsp products[https://www.minidsp.com/],i think.
