First let me start by saying that this forum has been a wealth of knowledge, and thank everyone for contributing and helping out. I've been reading and absorbing as much as I can for what seems like ages, and I'm finally ready to jump in and start my project.
I stumbled across a few of the now discontinued Peerless D26NC55 tweeters, and I've always liked the Modula NeoD CC design so I have decided to go with that. My intent is to build two mains and a center for now, but I purchased enough of tweeters to eventually build two more for surrounds down the road.
I've always liked the look of curved cabinets and came across an interesting construction method that uses many ribs stacked up to create the enclosure. I've attached a rough model I've started so you can get an idea of what I am referring too.
I've managed to keep the baffle the required 9" however because of the nature of this construction technique the opening that the baffle sets into must be wider. I've attached a cross section of the baffle set into the enclosure for reference.
My main question is will this additional width adversly affect sound quality?? I know Jon designed the crossover with BSC correction and I'm worried that my overzealous cabinet design may be ruining all the hard work he put into the design in the first place. I am going to have all the ribs CNC cut so I wanted to get a second (or third, or fourth) opinion before I sent out the design for quote.
Now as I'm sure you guys have noticed by now that there is an extra driver cutout on the baffle. My plan is to use this setup for both music and home theatre/movies and I don't have a sub yet so my thought was to integrate a small sub into each of main towers. Based on the geometry of the front baffle I picked the dayton RSS210HF-4 to use for the sub. The main speaker would be completely seperated from the the sub compartment. I am planning on using the subs ported in ~40 litres tuned to ~25 Hz. As well the Modula's will be built into ~40L also ported as I've read in other build threads that it is a better overall volume for the HiVi woofers.
Well I think that is it for now, but I'm sure I will have more questions as I move through this project. I appreciate any and all comments on the overall design, I've been reading and planning for a long time now but am by no means an expert and am willign to tweak things to make them better. So far the only thing that is set in stone are the drivers as I have purchased them, but everything else is open .
Thanks,
Jeff
