Home Forums DIY Speakers and Subwoofers Changing the box dimensions on the Cinema 10 and Soundstage 15

    First new topic here and recent sign up. I’ve purchased the plans to build cinema 10 and Soundstage 15 and the components from PE. I planed to use the SS15 as L&R with the C10 as centre and rear surround and then put the Atmos 10” design that @123toid wrote up as well.

    I like listening to music as well which is why I chose the SS15 as L&R and these will be going in the family room of a house renovation so I can build all 7 of them into the walls which will also help conceal the massive speakers to keep my wife happy.

    I plan on running it from an Onkyo TX-RZ50.

    I have a few questions please;

    – It was suggested in another post to use the SS15 as the centre too and thought I’d start a new thread on it, I didn’t plan to do this as they are pretty big and I didn’t think I could fit them underneath the television without it being too high on the wall, but would be happy to if there is an idea to change the box size of speaker layout to make it more wide than tall without compromising sound? Or am I best to use the C10 as the centre? How much difference will the two be given I can use Dirac live to correct with the RZ50.

    – The C10 as rears have to be mounted about 2.5 m from the floor in the wall so I was thinking am I able to change the dimensions of the box keeping the same internal volume and angling the speakers down without compromising the sound quality?

    Looking forward to making lots of sound and have fun building them too. Thanks for the ideas and design too.

    Adrian the answer to both of those, is you can do that. You don’t need to change the size of the cinema 10 though. I would just make an angle bracket and angle it that way. That is going to be the easiest way and it will also ensure you wouldn’t need to reposition the ports. If you make the bottom much smaller, you will want to move the prots to give them ample room to breathe.

    As far as the Soundstage 15, I am guessing you are just hoping to save the ports. You could even place the ports up higher (between the waveguide and the woofer – if you can get them to fit well) and then just deepen the box. THis would allow you to cut the bottom part off below the woofer.
