2nd order LPF for RS225-8

[btAudio]

I've learned from this site that RS225-8 has been extensively used and highly respected. Can someone recommend a 2nd order crossover for the RS-225 in a 1.6 cf box ported box? I did find a couple of threads but I could not find something similar to what I was looking for. Unfortunately I don't have the time to become an expert the design tools out there and this is my first build in 20+ yrs.

Thanks in advance!

I use RS225-8 here:
10F/8424 & RS225-8 FAST / WAW Ref Monitor

And here:

Passive XO for Time-Aligned RS225-8 and RS28F in Waveguide

The second one has not been tested yet. But I predict should be very good too.

Re the second project above, the RS28F is unfortunately no longer available, at least at Parts Express.

It was replaced by the RST28F but it has different specs. It might be possible to obtain some s/h or old stock of the old model, it was a very popular tweeter - I wish I'd bought a pair!

It might be possible to adapt the XO above for the new tweeter, but it would need some work, here's a recent discussion fyi:

I did look at some of the threads from above - as you know the RS225 FAST thread is quite extensive. To be honest it's not obvious to me how to adapt your design to what I'm trying to achieve. My goal is to use Morel TM4055-8 with the HF and MF crossovers from the Cornetta with the RS225 @ 350 Hz for the bottom end. I'm a novice and hoping to hack something together based on the robust analysis others like yourself have contributed to the community.

I have had success swapping the RST28F into RS28F designs. It’s very close.

That's interesting, thanks!
