[QUOTE="Peter Morris, post: 148105, member: 652"] Re: FIR filters "In the case of EAW" ... yes in many cases they did get less SPL. For example the KF730 lost about 4 dB when focused. They pushed the drivers much harder than the IIR settings, for example there was an extreme amount of VHF boost all the way up to 20KHz :-) I think there was something like 24 dB difference between the low cut on the HF driver around 1K5 and 20K! I did actually reverse engineer the settings and modified them for more power :-) [/QUOTE]
