  • Help with build Ideas

    Moving into a new house, and will not have a lot of time to set up a living room music, so I wanted something quick & easy (I hope). I have receivers and stereo amps, players, streamers, etc already, so just speakers I need help with. I have 3 x Def Tech UIW RLS II inwalls that I no longer wish to use as inwalls. https://www.definitivetechnology.com...rls-ii#Reviews I was thinking of mounting these on a baffle of approximately 9"" wide and building a plinth to mount them on for LCR combo, These units are completely sealed, so a quick and easy solution, with the proper baffle width. Then i started thinking about bass>>>>, so I would like some ideas on the following:

    1. Keep the RLS II units and build bass bin for them.. Something along the lines of the Paul Carmody Sunflower speaker. Use the other RLSII for a center channel (ie: horizontal on a baffle)

    2. Build the RLS II unit into a FAST/WAW enclosure with a helping larger woofer, again using extra RLSII for center channel.

    3. Build the RLSII on the plinths as in opening paragraph, and add remote subwoofer or subwoofers.

    4. Tear the RLSII apart, and build a brand new design, with the hope of enhancing then output of the drivers and PR's (larger PR's, more box volume, etc).

    Note: I do have some other small speakers I can use while thinking about these Def Tech units, so I will not be without music. I also have some Dayton drivers waiting for some projects (Peds or similar, and a larger version of Tritrix or the Sunflowers), once I have my workshop set up.

    Looking forward to your comments and ideas, as I am just getting started on my journey into audio creation. I think this is why #4 appeals so much, as we all try to build a better mousetrap. I thank you for your time to help me.

    I would imagine the inwalls are voiced to be used ... in the wall and might sound a bit bass shy, among other things, if mounted sans wall reinforcement. May be just as easy as playing around with eq in the receiver. Do you like the sound of the deftecs?

      Thanks for the reply. These have never been out of the box. I just know that in walls or on walls will never fly with the wife in the living room. I am looking more towards 2 speakers, one each on the sides of an audio stand, with a CC on top of the audio stand. I can make it easy as in the opening paragraph, just to see how they sound, and then decide on what to do with them in the future. If I mount on a baffle, would a 9" or 10" baffle be adequate.

        My wife would be ecstatic if the speakers were in the wall and not sticking half way into the room ... all 3 big a$$ pairs of them. Are you able to install them in the wall and cover them with something resembling artwork? That would make them all but disappear. I've seen pics of exciters mounted on panels (think dml panels) where someone had an artistic hand and they looked like really nice pieces of art hanging on the wall.

        My $.02 is that an inch is not going to make much difference to a speaker designed to mount in-wall.

        Something like the Sunflower would be pretty neat. Simple 1"x10" to mount deftecs onto and a side mounted sd215a-88 in a small sealed box as the base. Do not like their flimsy stamped frame but they are cheap, play above their <$30 price tag and should play high enough in frequency to blend well with the deftec.

        Personally, I wouldn't tear the deftecs apart.

          Kornbread,

          I understand about the WAF aspect of inwalls. I might want to try the baffle concept first. If they sound OK, then maybe work on the inwall concept. Although the speaker was designed to be inwall, the speaker was deigned to be sealed, and then put inwall. In otherwords, it was designed to just another sealed speaker that would not be bothered by mounting inwall.

          Regards

            From their picture, it looked like they were already sealed?

            I listened to a couple deftecs models a long time ago and they sounded pretty good, although I am sure things could have changed over the years, it would be a shame to tear them apart just to scavenge the drivers.

              Thanks for all the help Kornbread. Members on the DIY audio forum are encouraging leaving them as inwalls also. I may get the wife do something artistic around the TV, so the inwalls would look hidden. No use taking this thread any farther.
