Superdave Posted April 22, 2016 Share Posted April 22, 2016 I'm considering of relocating my 2 front subs to the wall side and having them fire out at an angle due to the space limits. I have a made quick mock-up drawing for reference. Would there be any unforeseen issue(s) to consider with this change as far as sound quality? Currently, the 2 front subs fire directly forward into the MLP. I have (4) rear subs that fire along the same wall. Here's a video of my current set-up for better visual reference. 1 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted April 22, 2016 Share Posted April 22, 2016 I don't see a major problem Dave. Just measure the response and fix the FR. Good to see you on the forum again. You did a great job with the HT. Now time for you to get some deep sea fishing done! Quote Link to comment Share on other sites More sharing options...

Holy crap, what was that movie at the end of the video? Game of Thrones. I think this was from season 2. Quote Link to comment Share on other sites More sharing options...

Paducah Home Theater Posted April 22, 2016 Share Posted April 22, 2016 (edited) My only thought is that you're basically turning that area into a giant 4th order bandpass box. There may be some frequencies that get boosted more than others due to the resonance of that cubby hole.

derrickdj1 Posted April 22, 2016 Share Posted April 22, 2016 It would be nice if you could somehow test the side wall location before tearing out a piece of wall. He may get a bit more spl with the change but, it needs to sound good also. Quote Link to comment Share on other sites More sharing options...
jason str Posted April 22, 2016 Share Posted April 22, 2016 (edited) Looks as if others gave decent opinions but would personally do a test run before making anything permanent, you may need to adjust your driver to boundary distance and move it accordingly. Looking at your drawing there is room to fire it straight into the room, why the odd location and setup if you don't mind me asking ?

Hi Jason, I have other items behind that wall and that's why the boxes would need to be angled in. Just fyi, i'm not opposed to keeping my 2 current front subs in their respective locations and adding these 2 new subs angled in. Quote Link to comment Share on other sites More sharing options...
Superdave Posted April 23, 2016 Author Share Posted April 23, 2016 I'm interested in the new SI DS418, but they are 2-ohm per coil. I'm trying to figure which amp would also be best to run these (2) dual 2-ohms along with my current (2) dual 4-ohm 18's without the amp clipping or causing the smoke to come out.

derrickdj1 Posted April 23, 2016 Share Posted April 23, 2016 An I Nuke 6000 DSP amp would work. Yes, keep the front subs for some balance. Quote Link to comment Share on other sites More sharing options...

Superdave Posted April 23, 2016 Author Share Posted April 23, 2016 Does the baffle go floor to ceiling? No, just the size of the boxes stacked upon each other. Quote Link to comment Share on other sites More sharing options...

I see a nice area for a line array of subwoofers if you really need to add to your current 18's. May be a bit of a pain to set them all up together but if you were not adding the same driver in your new sub it would be about the same amount of extra effort. Depending on the width and height you had available behind the wall there could be many options. Quote Link to comment Share on other sites More sharing options...

Wire them in parallel to a 4 ohm load and put one on each channel of the amp. Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted April 23, 2016 Share Posted April 23, 2016 (edited) Wire them in parallel to a 4 ohm load and put one on each channel of the amp. You probably mean series. Parallel would be 1 ohm nominal on a 2+2. Although, what most people don't realize, is that if you look at the impedance curve of popular 18's, by the time you get to a little over 10 hz, the impedance is twice what they think it is. I'm running four subs in parallel on one amp channel, basically a 1 ohm nominal load. Usually it's significantly higher than that though.

derrickdj1 Posted April 23, 2016 Share Posted April 23, 2016 You probably mean series. Parallel would be 1 ohm nominal on a 2+2. Series is correct for a 4 ohm load. Thanks Metro! 1 Quote Link to comment Share on other sites More sharing options...
Superdave Posted April 24, 2016 Author Share Posted April 24, 2016 Do you think the 6000dsp could handle a 2.67ohm load per channel? Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted April 24, 2016 Share Posted April 24, 2016 Do you think the 6000dsp could handle a 2.67ohm load per channel? That would be three 8 ohm speakers in parallel. Not sure what you're thinking. Quote Link to comment Share on other sites More sharing options...
