  • Rs-p wmtmw cc

    seeing as i built the Paper Towers and the Paper surrounds i was thinking of completing the system with a Paper CC .RS180P-8,RS125P-4 and RS28F. i have all the parts on hand and enough 1/2" ply to build a box good enough for measurements . here is a quick sim i came up with ...




    any thoughts and or opinions ?

      thanks Joe . you've read my build threads and know i need all the support i can get ! lol

      i also simmed RS180P-4 in series but i don't have those on hand . not too much difference , just a little in the impedance curve .

        I'm also here for moral support as an avid reader of your paper towers build. Good luck and don't leave any details out!

          my calculations give me 1.25cu for the woofers and .4cu for the mids .

            I do know you'll be told to squeeze those miss together and push tweet
            Up. Make sense?

              yeah . and we'll see once i take measurements . i know the tweet can handle it . towers and surrounds are crossed at 1800 ...

                That impedance and impedance phase looks really nice, Cool project!

                Is there a benefit if you have the height and being a center channel to vertically orienting the mtm? Or will this limit your vertical dispersion too much?

                  these are good questions that i'll be researching the answers to as i'm still a noob and learning as i go ... more to Joey's comments i went back into paint and drew this , it is not to scale and i feel like i'm 3 years old when drawing in paint but you get the idea . this configuration will be challenging with a 5" frame on the mid and a 4" frame on the tweet fitting the on a 9" baffle ...

                    Just my 2 cents, so long as you don't have multiple tiers of seating requiring wide vertical dispersion I'd go with a vertical MTM and angle the center up so tweeter axis is at ear level. Not an expert though

                      kind of my thoughts too . i've seen the mtm 45* vertical when i was building my towers and don't think it will be an issue for a center channel . i'll be in the sweet spot anyway and anyone on my couch left or right it will still sound really good . plus it could the be stood up as a L/R main if someone wanted to do so ...

                        How close to walls, or TV screens will these be?

                          front of speaker will be about 30" off wall and the TV will be sitting on top of it .

                            Two mids in series will still be 86dB sensitivity. The woofers will be 93dB. The tweeter is roughly 90dB. If the speaker is out from the wall in front of a projection screen, this should work OK. If the speaker is near a flat panel screen mounted on the wall, I think you will have problems getting the tonal balance correct.

                            What you have is basically full BSC. For centers, I prefer a more prominent midrange and treble.

                              i understand what your saying , but how did you get 86db ? the RS125P-4 are listed at 90db ...
