2way with CSS FR125 and RAW RA104.5 ribbon tweet - design help needed

[JRace]

Looking to make use of some older parts from some Raw acoustics kits.

i have a pair of RAW acoustic OB2x, OB3x and a pair of CSS FR125.

As i no longer use the OBX's or the FR125's (a Frugelh Horn with Alpair 7.3 took there place) i am thinking of repurposing the drivers.

Driver list:
CSS FR125 - x2
GR Research M-130x - x4
GR Research M-165x - x2
RA 104.5 x4

To start with I am looking at building a 2 way with the RA104.5 tweets and the CSS FR125 as wide-range mids mounted in a Parts Express .25 ft/3 curved cab (as I already have them). Then later I may augment the bass by repurposing the GR drivers.

For now, would the FR125 work well paired o the ribbon tweet?
If so what crossover point should I shoot for and should i put any crossover on the FR125 to limit its HF?

Ay advise wold be apreciated!

Thanks!
The HT3 used the FR125 with the ra104.5 and the extremis 6.8, i found an old review I wrote on them 6yrs back, and it states XO points of 4kHz and 180hz.

Should be a good starting point.

Yes send me a email I will send ya the crossovers you are looking for.
If you want the HT3i or HT2i or Dave can send them to ya.No problem Dave I give ya the go ahead or ya can post them here.

Digging out the HT2 XO, i am reminded that it was an MTM.

You'll need to use the HT2 XO to figure out what parts to toss in the HT3, and then you'll likely need to adjust the padding on the tweeter to get the levels right.

Al may hav esome suggestions.

Send me a PM.
We can talk.These are the original designs for both the HT2 and HT3 were changed with new crossover designs thus the name HT2i and HT3i

Your have other options, in that mix of drivers all depends on what you are looking for.2 way 3way tower bookshelf ect.
