Long Time lurker...first post...Dayton RS WMTW and Mains Question

[plincoln]

Hey guys, been reading the forum for some time now, and I'm toying with the idea of building the Dayton RS WMTW Center along with a new set of LR's.

I've read through the Dayton RS WMTW thread and tried to absorb as much as possible, but I have a couple questions...

1. Of course its a matter of preference, but those that have built the center, did you do Dennis' or Curt's XO?

2. The Dayton RS WMTW thread discusses some LR towers, but there seem to be a few different variatins floating around. I also see the Natilie P uses the same driver. I would like the Mains and center to match as close as possible. This will be primarily HT and I have an IB sub if that will affect the LR decision. Based on that, what would you guys recommend for the mains, and is there a shopping list available for those.

Thanks for being patient....

The mains in that thread are made to match that center. You would use denis's crossover for both. The mains there are TMWW's, They were designed to go together though.

[plincoln]

Just to be clear about it...

That's the dennis tower design I should be using?

[Hdale85]

Yep if you like i have a zip with all the info on it that i can send you if you pm me your email address. BOM Cut list and everything in it.

[ssabripo]

Kgveteran and I both used Curt C's XO design.....don't know anyone who has done Dennis' XO on the center.

the mains are design to match it, and are TMWWs, so whichever XO you go with, you would use the same for the mains and center.

[plincoln]

Maybe I'm looking at this wrong, but the center uses the dayton tweeter and the tower uses the Seas?

is there a design for Curts towers? My apologies if it seems that I need to be spoonfed, but i want to make sure that I have all my ducks in a row before I pull the trigger.

[Hdale85]

There is an RS28A version of the towers in the zip that im talking about.

Curts towers are the MTMWW's i beleive they are also dayton 3ways but they are very big. 50" tall 14" wide and like 18" deep i believe. I was thinking about building those but I think they are just a tad to big for my room.

great, thanks for the response. I really have no need for such large mains either . So I think I will go with Dennis' design.

Actually that is Chris' (cjd) towers. Curt has done a design for the WWMT to match his design for the WMTW. He is planning on posting the information today. Curt's design uses the RS28.

Dennis has a design for the WMTW that uses the RS28 only at this time. He does however plan to do a design using the Seas tweeter also, when time permits. As for the WWMT Dennis has designs for both the RS28 and Seas tweeter.

so much information

any plans for rears in the near future to match the fronts?

[Hdale85]

Actually he designed it already i believe as its in the zip file i got from curt maybe? i cant remember who i got it from now. But its got a Seas H1212 and RS28A version in it, unless dennis didnt design it?

I was thinking about doing a tower version of the modula MT's to match these(for rears). Would they match up very well?

But I just saw that they use different tweeters. Would it need to be completely different to drop in the RS28A or H1212? I'm guessing thats a yes as the one it uses are soft dome and these are metal dome.

That is the design from Dennis. As far as I know he is the only one that has a design for the H1212. The H1212 design was done at the request of Jim Holtz.

Just to clarify things:

CJD (Chris) - WWMTM using the RS270, RS180, and RS28.

Dennis Murphy, CJD, Jon Marsh, Curt Cambell - WMTW using the RS225, RS150, RS28.

Dennis Murphy and Curt Cambell - TMWW design using the RS225, RS150, RS28.

Dennis Murphy - TMWW using the RS225, RS150, Seas H1212

The Modula MT should work well for surrounds since the voicing of the RS drivers are pretty close across the board.

Look further in the thread. There is a RS28 version as well. That is the one that I built.

[Hdale85]

Ah my bad Well then i think thats what I'll do for the rears and if i do 7.1 then i may use just the standard modula mt's and then a set of modula mt towers. Then again mayne i'll just use all towers as then i wouldnt need to mount them on the walls or on stands or anything.

the cutlist pdf files you sent me...I dont see the side panels on either pdf

[Hdale85]

Look at the bottom where it says bill of materials. (look at the one in the seas version thats where im looking) It has under there Front/Rear Baffles, Side Panels, Top/Bottom Pannels, Bracing.

ok i was looking at the cutlist pdf files for the RS28. its not in either one of those pdf files. Clearly it should be 20x42...whipping up a 3d model of th enclosure right now

OK..so now I am a bit confused... The panel dims that are in the RS225-RS150-RS28 3-way folder do not match the Murphy Blaster RS (Seas H1212 version) 3-Way folder...

Which cut least should be used?

The RS225-RS150-RS28 3-way has a cabinet depth of 21.5" outside. The Murphy Blaster RS (Seas H1212 version) 3-Way is only 13.5" deep

As there are multiple xovers there are also multiple cabinets

Jim built a smaller sealed version (Murphy Blaster RS). The other is ported.
According to Dennis the sealed version is the better sounding design.

Look here:
Sealed & Ported Layouts

I plan on building these. Probably three. I only use one rear center. I like the bigger woofer(180) over the (150). Can't wait!

OK... Gotcha. Are there two version of the Murphy blaster? One with The RS28 and the other with the Seas? The cabinet would be the same I presume. Since I am going to go with the RS28 in the center ... it should naturally be in the Towers.

[plincoln]

ok..here is the ported version of the TMWW:

here is the sealed center channel:

I'd ask that someone double check these. Some of the dims were tough to make out. Also if someone wants to provide me with the correct counterbore depth, I will update the drawings.

I can provide model files to anyone that wants them. The counterbore for the drivers needs to be double checked since I dont have one in front of me to measure.

Anything else?

Hi Thomas,

I'm the one that created the zip file with all of the desgns that Dennis created plus cutlists, construction pictures etc. I can send it to you this evening if you like.

Any chance of getting you to do one of these for the sealed version and the center?

I know in your center thread, you had to relieve the back of the midrange on the inside panel of the baffle...what size was that? and I will update the drawings for the cabinets.

[Hdale85]

I emailed thomas the zip already. And i do remember you sending it to me now

This is done with a 1/2" - 3/4" roundover or chamfer bit to open the backside of the panel so the speaker is not masked (it can breathe).

well all i need now is the dennis murphy center shopping list for the xo and Im ready to roll.

[FlashJim]

Do we have a link for the zip file yet? If space is needed, I have a webserver.

[ThomasW]

Didn't know anyone was waiting for them I sent them to you in an email.

[FlashJim]

Just got back from lunch. Got 'em! Thanks Thomas.

[dawaro]

well all i need now is the dennis murphy center shopping list for the xo and Im ready to roll.

I am in the process of doing one for both DM & CC's designs right now.

I have loaded the design in LspCAD and I am changing some of the odd values to reflect available values. Before I post anything I want to make sure there are no ill effects from the changes.
