Fullrange 100 hz and up

I was thinking something better and more suited, like the Visaton B200. If budget and/or shielding are issues then the FE127E does really well on OB. Then you can use those later as outstanding computer speakers when you upgrade to something a bit better like the B200.

I wouldn't think a 127 on an open baffle would be able to reach very high SPL's due to a limited excursion. The 207 would probably be alright on open baffle at high volumes, I would however make sure to have it crossed over at 100Hz. Note that the response of the driver will already be falling by this point so you take a carefull look at your crossover point/slope. And depending on the size of your baffle some EQ might be needed.
I would probably stick with a sealed design if you wanted to keep the complexity down. I don't know about bass, but I think as far as treble/midrange a large sealed enclosure can perform (please no flames) quite well, and will hold it's own against open baffle. Everybodys taste and priorities are different though.

I use the FE206 on OB, but it definitely needs a helper woofer. You might be able to use a shallow slope XO on your woofers and a little EQ on the 207's to get away with not using an additional driver.

Since you already have OB for the bottom end, I think using a FR that gives you the ability to go OB results in more flexibility. You can always put them in a box later.

Re the FE127, I've run mine pretty loud (approaching 100db) without a high pass filter, so cutting them at 100hz may get you there for under $100/pr .

100db in open baffle with no crossover? I would think you would be pushing well past the excursion limits on a regular basis. Fostex drivers are not exactly known for their huge excursion capabilities. Have you tried it with a high pass? I would have to imagine it would clean up the sound. I ran my 108's in a sealed enclosure for a while with no crossover, I've since switched to running them with a capacitor to ease the load on the little guys. It's really helped clean the sound up quite a bit.
just a thought.

That was just temporary. I didn't play them that loud with any bass heavy music. I'm just waiting on my active XO to arrive. I tried them on my Denon HT receiver, using the small setting, but I could hear that XO too much and they were much smoother with it running full range. I can't wait to see what they sound like with a good high pass filter. I have a feeling I'm going to like them better than my FE206's with the helper woofer.
