I am building a DIY subwoofer project.
I would like some opinions of my ideas.
Non powered remote amp.
The subs I am using are car audio subs. I know I know not the greatest idea but they are a great SQ subwoofer. Model is Soundstream R-12SQ with an xmaxx of 16mm. Rated 25hz to 1500khz 120oz magnet, dual 4ohm 4in VC in series showing a 4ohm load to amp. 600 watt RMS. I plan to cross it over at 20 hz high pass and 120hz low pass.
I post more info if needed.
I want SQ for music and movie capability (50/50 movie and music)
I am putting 2 of them per cabinet (building 2 subs).
My idea is one down firing and the other front firing.
I am not sure if I want to use a sealed or ported box.
1 inch MDF then covered in cabinet grade ½ inch Cocobolo wood with a custom DIY front grill. I have to make it look like furniture to appease her. No real size restrictions though if it they look good
Room is 20Lx14Wx9H.
Amp is QSC GX5 rated at 700 per channel @ 4ohms
Crossover is Behringer DCX2496 Pro
[email protected] 12 gauge connectors and cable.
1. If I go sealed can I put both in one chamber or should I use 2 chambers. Sealed volume is 1.3 cu ft. per speaker. So box should be 2.6 cu. Ft. I assume then adjusted for bracing and sub volume.
2. If I go ported box volume is 2.0 cu. ft. per speaker or 4.0 total again adjusted for bracing and sub volume, should I use a slot port or round tube? Can I use one chamber. What should I tune to? Recommended is 29hz. 2x 4in x 16.75 tubes, will it play to 25hz if ported to 29hz?
3. If sealed I will fill to half with poly fill, but if ported should I line it and with what if so?
4. How much floor clearance would I need for the down firing speaker if I can build it that way?
5. Will using the DCX2496 after the line out from my receiver also boost the voltage so that I get full wattage from the amp?
6. Can I put one driver on each side of the box if I do a sealed box without a middle divider?
Thanks in advance for any ideas or even criticisms.
