Help me build a new center!

[jmcox44]

Ok, I'm new to this forum and have been reading a lot lately trying to figure out what the best design for a new center channel speaker would be. I've looked at the Dayton RS WMTW and the Modula MTM and i have a few questions. First off, the Dayton RS will not fit in my TV stand, it is way too large. The Modula MTM, however, will. So my plan was to build the Modula, the only problem is that i wanted more bass output out of my new center. (My current center is a Polk Audio CS-250

So my question is, would it be possible (and smart of course) if i used the Dayton RS180S-8's (7" drivers) rather than the RS150S-8's in the MTM design? Also, if this is possible, what exactly would i have to change with the crossover.

Thanks in advance.

I think you may be underestimating the low end output from the Modula's. I personally don't have them but it is pretty substantial. As far as I know the Modula MTM X-over wont work in regards to be used as a center. The X-Over is setup to be used in a vertical setup.

Also I'm confused about the last part.

So my question is, would it be possible (and smart of course) if i used the Dayton RS180S-8's (7" drivers) rather than the RS150S-8's in the MTM design?

The Modula's use the RS180 7" drivers. Do you mean using the RS225 8" driver? If so that in itself would be a feat. To much of a gap. I wouldn't second guess output capabilities the Modula's, I say go for it.

Well i was just looking at this link, and thought near the bottom was the model for the rsa28 tweeter. And according to the top it uses the 150's rather than the 180's. I mean correct me if i'm wrong, i just figured the 180's would get a bit more bass output. Anymore advice would be great. Thank you.

If you feel like waiting till sometime before Christmas, Evil Twin will have a WMTW center design out using the RS180/RS52/Vifa D26. It'll be designed for the Dayton pre-finished 1ft^3 enclosures (or a DIY enclosure with the same baffle width driver spacing).

Jacob,
Evil Twin is presently designing a new WMTW center channel speaker that utilizes two RS 180's, a RS52 and a Vifa D26NC55. It will fit in a stock PE MTM box with a 9" wide baffle that is used for the Modula MTM and NatalieP. I have no doubt that there will be BASS!!

According to ThomasW it will be a "pre-Christmas" event! :B

I am currently using Modula MT's as my mains and surrounds, and the bass from a single RS 180 is quite impressive. 8O

Seems like it will fit your needs (and many of ours) perfectly. :T

Cheers,
Bruce

Will,
:agree:

We must be on the same "Evil Twin WMTW Wavelength" tonight.

Didn't see your post until mine was submitted.

Chers, Bruce

I hope we aren't hyping it up too much.

I was about to order some of the parts for it the other day since the RS52 is on sale at $28. 8)

The problem ET is having, is getting drivers delivered from PE while he's traveling in Europe.

I've got a stack of hardware and software sitting around waiting for him to be in town long enough that I can get it shipped to him......:banghead:

Think Thanksgiving week and the week after (hopefullly). I'm planning a week off at Thanksgiving, though lord only knows my boss may have other ideas.

[Brian Bunge]

I've got a pair of RS52's that I really won't need for quite some time. They are new in the box, never used. I'd love to trade someone for a pair of RS28a's if anyone is interested.

I am so confused ...........................

Evil Twin = JonMarsh ??????????????????

Can't you tell by my build thread that I am slow.

Man, what a christmas present. 8) You're the man, Jon. :T

I have to tell you, I caught a bit of Back to the Future 2 on TV last night and the second I saw Christopher Lloyd with his crazy hair I thought of you. :rofl:

Brian, maybe we can work a deal- I have a couple of pairs I believe in my climate controlled storage unit. Won't be back in the country until Friday, though, so I can check Saturday if you're not in a rush. I can give one to ET, and keep one myself for the CC design shoot out.

Let me know if that's interesting.

BTW, I've got about 3 pair around if my memory serves me correctly.

Yeah, that's heavy. (Did something happen to the earth's gravitational field?)

you know, I'm really hoping that set comes out some day on high def DVD; I've got the laser disk set, and the DVD, now I need just a little more resolution.

Considering how good a job they've done with some MUCH oldeer movies on HD-DVD, I have real hopes. My daughter and I used to watch these all the time when she was little- by HER request! (of course, in 1989, most folks didn't have what we'd now call Home Theater (Zenith CRT front projection, sub with mains), and she and her friends thought it was hecka cool.

Jon,

That should be fine. I just want to finish my big center channel soon and for some strange reason I ordered the RS28AS way back when I originally ordered the drivers for the center. If I finish before I can get the tweets from you I might just use it so that I can compare how it to the non-shielded.

[jmcox44]

Ok I decided, due to the parts being on sale now, that I'm just going to go for CJD's RS150 MTM design. My only question is would it be better to go ported or sealed? I have a Onkyo SR-TX573 crossed at 80Hz and a Tempest 15" that takes care of the low. I think I understand that its better to go with sealed when you have a sub, but still curious.

Thanks,

Jacob

Edit: Also is it ok if i go with the non shielded version of the RS28 since i have a DLP rear projection TV? Thanks again.

[BigJim_inFLA]

Jacob,

I used CJD's rs150 design for my center channel for a while. I built mine sealed and crossed to the sub at 80Hz. It sounded really nice. I used the non-shielded tweeter and I placed my 27" CRT right on top of the speaker with no ill effects. I don't think you will have a problem.

Jim

[jmcox44]

Thank you very much. Exactly what i needed to here. Time to lay down $150...ouch
