The following was put on the Open Baffle Forum, after some testings I chose M130 as my midrange driver, read explanation below:
I thought I will share with fellow OB builders on what I have found experimenting with a no. of OB configurations.
1. Full range(FR) and U frame woofer
a. FE167E (FR)
b. Hemp cone (FR)
2. MTM and U frame woofer
c. SEAS paper mid and dome tweeters (MTM)
d. GRresearch M130(8 ohm version) and B&C compression drivers and horns(MTM)
At this stage I am finalising my mid and high freq first as my woofers are of inferior quality and will be upgraded later.
The last option d. gives me the sound that I like the best, large sound stage, very open, very efficient and very dynamic. I am using active x-over, DCX 2496 and possibly would be able to use passive components if I decide to at a later stage.
The option d. combo is very cost effective the total price for 4 mid drivers and 2 compression drivers and horns are only about US$220 not including postage. All these can be obtained in the States.
Refer to Open Baffle Forum for more details.
Thanks Danny for such a good driver at an excellent price and service.
