[QUOTE="Jack Arnott, post: 140830, member: 304"] Re: 60 Degree DIY Mid Hi Hi Guys, I don't have anything to add to the limiter settings beyond what the calculator, and BMS's specs say. A couple of thoughts on the subject. 1) I don't sell very many diaphragms, to my way of thinking. But I also don't know what some of the OEM manufacturers stock and sell. 2) The post about frying the HF diaphragms, I dont get that. I have not sold or loaned any drivers to that user. So there must be some kind of myth, or misconception on how the driver should be used. 2A) I sell almost the same amount of HF and MF diaphragms. 3) I would be interested in how the cabinets are doing in regards to the different bands, and limiter settings. EG, most of my designs are not very aggressive in regards to the HF/LF or Mid High/LF, such as pairing one 1" driver with a 12", or one coaxial compression driver with two dual 15" speakers. (Even my unity type box with two dual horn loaded 12", in a 40x20 horn, the mid/highs kind of loaf.) As such, I don't push my compression drivers very hard.
