[QUOTE="Andy Turner, post: 204725, member: 10677"] Max, Mark. Thank you both for your input. I get your point about aiming for a flat FR. It really makes sense, though it is tempting to establish the 'nice to the ear' setting as the baseline. Max: Yes I am using the HF950, but to be honest I don't really trust the readings in the high range, mainly due to the mic. Thank you for the advice on using Smaart. I agree with you that the result is better so far, - and also faster to work with. Mark: What subs are you using? I found another strange thing is that I need to gain +6db on the 12" horn even though they are 8Ohm's in parallel and the BMS driver is 16Oms? The measurement below is made indoor in my summer house, with the mic 60 cm from center of HF950 with the box sitting 1 meter from the floor and 60 cm to back wall and 2 meters to the side wall. PEQ's on the HF and VHF (passive XO) are: 4.75k +3db Q=3.42 and 3k -4db Q=4.41 EQ's on a 1/3 Oct. GEQ: 800 -2.5db and 2k -1.5db +6db on LF(12") [ATTACH=JSON]204726.vB5-nodeid=204726[/ATTACH] Even though the sound is a little rich in the low mids, and also a little on the dark side lacking a bit of presence and treble, in return is very relaxing and no ear tiring tendencies or harshness. Not at all my prefered tonal balance, so needs some work. I will make some new settings measuring outside using Smaart to try to get it flat without the walls. Any recommendations for a measurement mic in the 100USD price range? Thanks. [/QUOTE]
