Hello-

I'm wondering what the distance/power was on your frequency plot? I'm interested in using those drivers as well and wondering if 2 drivers in parrallel is enough to get to 90dB 1w/1m? Let me know if you would-

Thanks-

Ryan

The measurement was taken at a distance of approximately 2 meters, on a forklift in the middle of a warehouse.

Perhaps it would be better to address your concern directly.

Are you planning on driving the speakers with a one watt amp? Making basic assumptions having the two drivers in parallel in an enclosure is going to provide 87db sensitivity with one watt, conservatively. It could easily be more. I didn't apply 2.83 volts and use a SPL meter to see what the output was. It may be more appropriate to ask if the drivers can achieve the necessary SPL without suffering significant compression loss. If you're looking for 90db, that's no problem.

Yea sorry a bit vauge there-

I am looking to pair some 125's as dedicated mids with a hiquiphon or possible morel supreme tweeter- I would prefer not to pad the tweeter down too much. The huquiphon OWII is about 90dB 1w1m and the 130 is 91.5. Anyway I know the math 2drivers= 3dB 3drivers =4.8dB 4drivers =6dB. And those figures should double given perfect acoustic and electrical coupling so 3dB conservative realworld maybe 4-5dB depending. . . That is why I was asking. Here is a better question-

How sensitive is your tweeter and did you have to pad it down at all?

Also I'm looking to easily achieve dB's in the 110-120's (for overhead purposes) but for that reason the wr125's would also be HP filtered at 200-300hz. And no I don't listen to music that loud- but these will be studio monitors and typical music with a band starts off with a very wide dynamic range. Studio monitors either need limiters (yuk) or rediculous amounts of headroom. Try plugging a bass guitar right into your system and you will see what I mean.

Also I could not find a power rating for these speakers- in your best estimation how much SS power can your system handle (with the 2 125's)?

I really appriciate your help-

Ryan

You may want to read the specs PDF on the Creative Sound website for the WR125.
http://www.creativesound.ca/pdf/WR125S.PDF
Dan W. ran several measurements including power stepping where he concluded that 3db compression occurs at ~99db so it's possible they could meet your requirements especially since you would be limiting them to the mid-band. His conclusion for a power rating was 35 watts. If you're not operating them below 200-300Hz they might meet that criteria also. I'm using a single WR125 as a mid-range in a setup where I've ran the system at near ear-bleeding levels with pretty good results.

I'm currently looking at a 2nd order XO solution to address the 7kHz bump. I'll assemble and test the XO this evening and post my results.

How hard would it be to do this design with a different tweeter, say, a Vifa DX19, Hiq OW1, AC G2Si? I ask because the fostex tweeter is something of an unknown quality to me, and there are several very good tweeters in its price range.
