Stepping back into a project I started a few years ago, but set aside as I became busy with other things. Here’s what I have. A pair of Acousti-Craft speakers that I got from my grandfather. I replaced the drivers that were in there temporarily with GRS 8FR-8 full range. I’m looking to convert these to something that sounds much better. The original TechTalk thread I started for this project can be found here. I’m looking to get some thoughts from the DIYAudio community as well.
I’d like to redo the driver setup on these so that they work about as well as they can for the purpose of 90% TV and movies 10% music. Positioning two to three meters from listeners and speaker centers about 5 to 8 feet apart. 6 to 8 inches off the wall and pointing straight ahead, no toe-in. Good imaging and soundstage would be desired for that immersive movie experience. It will mostly just be me using these, but I would like the sweet spot to be fairly wide if possible for times that it’s not just me. I’d like these to reach down into the mid to low 30s so I won’t have to add a sub.
I’ve been doing a lot of research on what I can do with these and keep coming back to a 2-way. I’m guessing any full range options would beam too heavily for the positioning I will be using these at and also not reach the low range I would like. 3-way is increased cost and crossover complexity with potentially more extensive cabinet mods than I am wanting to do.
As pointed out to me in the TechTalk thread, the RS225-8 is a great match for this cabinet. From what I’ve read, I’ll likely be very happy with the performance of it, but if anyone feels I should consider something else, let me know.
Tweeters have been more difficult. Top of my list currently are the Wavecor TW030WA 11/12, either of the Peerless corundum or one of the SB Acoustics SB26 variants with perhaps one of the Soma Sonus waveguides. This is probably the biggest thing I need help deciding on now. Anyone have any opinions on what tweeters out there would work best for, hopefully, getting close to my goals while crossing low enough for the RS225?
Attached is an FBX of a model I created for visualizing potential cabinet modifications. It might be useful if someone has recommendations on adding bracing or wants a better idea of what I’m working with. Still trying to decide if I want to preserve the original look of the cabinets or make some minor changes such as getting rid of the grill cloth and having a more decorative front baffle with exposed drivers.

Hi Chris,
What is the volume of the cab?
What are you driving them with?
Are you apposed to ported?
This info may be in the techtalk thread but you will get better assistance if you make it easy for others to help.

I think the volume was about 51 liters. Probably loose a few to adding bracing.
At the moment I have a Yamaha s202, but will be looking for something else. I don't think the s202 will output below 40Hz.
I assumed I would be using a port. The RS225 would need it to get as low as I wanted.
