Okay, so I did a bunch of measuring. I don't have a ton of experience with measuring speakers but I think I got some conclusive results.
I used a Firstwatt F6 amp with the signal coming straight out of the headphone jack on my laptop. While the amp would work well, I know that the laptop DAC is probably not the best at least for fidelity. I decided to test them outside to create a more anechoic environment and avoid room reflections messing up the results.
-I took 3 measurements 37.5" from the front and repeated the same measurements from the rear of the speaker (due to the ports)
-I averaged the front results of each speaker.
This is what I got
The Daytons seems to go a bit lower. I think this is mainly due to the fact that I took a bunch of stuffing out of the enclosure. The port can work and do it's thing.
I like the results. I feel as though if I had the cabinets completely stuffed again as it was from the factory, I would have similar results to the OEM driver. The Dayton does seem to be a bit smoother as well. I like it and feel as though it is a good fit. Let me know your thoughts if you guys have any. I have the files and would be happy to share them via Email. Just PM me and I will send it all over.
There are a few other things that I like about the RS225-8 for me personally.
-There are quite a few great DIY kits that use this driver. I want to build the Travelers by Speaker Design Works someday.
-They have been around for a long time, are cheap and highly regarded by a some terrific speaker designers.
-I have the Bordeaux speakers and will feel better knowing that I have backup woofers in case one ever fails
-Cast baskets, aluminum cone, good looking etc.
I am going to go ahead and purchase 4 woofers tonight.
-What I hope to also do to these speakers is veneer or wrap the bottom bass bin and make the woofers flush
-Look at the top cabinet crossovers and drivers to see what kind of shape they are in. I know I need one rearfiring tweeter which meniscus seems to have.
-Make a new top cap and wood trim for the rest of the speaker.
Replace the binding posts throughout. The two binding post on one of the top cabinets are missing the nut part that screws onto the post. The previous owner just zip tied the wires to the top cabinets. Lol.
-If I can get the crossovers out, I may change the wiring out. I have a bunch of low oxygen wiring laying around that would be suitable.
I do love the way mids and highs are voiced on these speakers. Von Schweikert did a great job of that. I just need to get used to the bass. What I do like about the lack of the bass bump is the room isn't loaded up with bass when the top cabinet is trying to produce it's magic. This helps with the imaging and spaciousness of the mids and highs.
