I've decided to use Chris' version of the Dayton RS 3-ways. Surround suggestions?

[WinstonSmith]

I figure I might as well jump in with both feet. In doing so, I'll be making 5 speakers. Before I tackle the two mains, I'm going to make the rear surrounds and a center. What would go well with this??

By doing things this way I have a chance to eliminate my 100 buck center and surrounds (that's for all three and yes they do sound awful) and use them while I complete the main speakers.

What's your suggestion?

Well, the ultimate is 5 of the same. If you are going with a front projector and a perf screen (one of the best is a DIY solution, ironically) then 3 of the towers up front for sure. This is really going to get you the best results sonically, but it takes room. At least 8 inches between screen and the front of the speaker, and ideally a foot or two behind so you'd need like four to five feet from screen to the wall behind...

Otherwise, I did a crossover in the WTMW 3-way thread https://www.htguide.com/forum/showpost.php?p=193911&postcount=83]here - it uses RS225's, RS150, and RS28 (you'll need to verify whether it was the shielded version or not, I don't recall...) - I'm pretty sure Brian Bunge has built this. It should voice-match very well. Some day I think I would like to do a WTMW or possibly some oddly shaped WMTMW center variant with the same drivers as the WWMTM's. I definitely can't build such a beast without near instant death though. So someone that can build and do accurate measurements would be needed, then I can tweak the crossover for it.

For surrounds, the Natalie P would basically get you the MTM portion of the bigger 3-ways and they're darned good speakers as they stand. Mark K's RS225 based TM would be another viable option.

With speakers that good, large and powerful, a phantom center may be the better option?? A center is really only needed to anchor sound to the tv for people off axis and with funky room environments.

Surrounds, if they are going to be wall or ceiling mounted, then you'll probably want the version of the Modula MT or MTM with the BSC effect for surface/near surface mounting, right? Or a similar project meant to be located so close to the walls.

How valuable a center is depends on the total setup, but in general it's worth having.

[Brian Bunge]

I'm in the process of building the crossover for the center right now (along with getting ready for Christmas, etc.). I should have the center done not long after I get back from GA.

Well I found the BOM for the Natalie P's. Ordered everything plus the RS28s for the other speakers as well. Too bad I missed the special pricing on the RS180's but I have only my indecision to blame for that. Heh, I get to build three designs for this project

I'll have to look at cabinet options for them. Although I'm a speaker n00b, there's not much I can't do with wood. Hmm... what to do, what to do.

Well, here are the general rules: baffle width, height, and driver placement is pretty much a fixed quantity. Altering it significantly will change baffle step and diffraction characteristics. However, these would look superb with curved-side variant, and there is limited amount of wiggle room in baffle dimensions/shape to play with. Don't hesitate to inquire, and feel free to post in the main thread so other folks can see what you do and answers to your questions.

Whatever you do, have fun! For me that's the most important part of this all.

Can you help me please find the BOM for the Natalie P's?

I'd be glad to. It's at the bottom of this post

Thank you very much WinstonSmith!

Am I correct that, that BOM is for the price of 2 completed speakers? And also, using that BOM, is it for the tower type like the picture I attached on my thread? https://www.htguide.com/forum/showpo...6&postcount=21

Thanks again!

Yes thats for 2 speakers but does not include building materials. The only difference between the regular and the towers is the enclosure it self. You might need an extra sheet of MDF but I doubt it. So it's probably just extra time and no extra expense as you already have to buy the MDF regardless of the enclosure type.

I'm so sorry but what are those "building materials"?

[Hdale85]

MDF, Birch Plywood whatever you decide to build with. The wood. Screws, glue and whatever finish you use.

And one more please, do you have the link to the detailed measurement of the box for Chris' tower? What I'm looking for contains the sizes of the holes for the drivers and where the holes should be, the height of the tower (internally) so I can measure the mdf. I saw a link at natalie p's thread but the jpeg file wasn't detailed. Sorry, i'm very newbie on this.

Hopefully, someone can send the measurements of JonMarsh's towers too. I saw the thread about it and read that when he brought it to DIY Chicago, it really had good reviews from the audience!
