You have quite a forum here. I've spent the last 72hrs digging in and I feel like I've learned a ton, yet still have lots to learn. I'm here to ask for your assistance.
I'm in the market for a new sub or 2, and thought I knew exactly what I wanted until I read a thread about how much more value there is in a DIY sub which quickly opened pandoras box. I then realized I had a Crown Drivecore XLS2000 laying around, which made the DIY decision even easier.
There is a lot of information out there and I've made some assumptions based on what I've read. Please don't hesitate to tell me my assumptions are wrong, that's why I'm here. That's why I'm asking.
The only reason to choose sealed over ported is if space/size of enclosure is of concern. If you've got the space, go big and go ported.
When talking about woofers from the same line, a 15 is going to be superior to a 12. The surface area is going to allow it to push more are and create more sound. The idea that a 12 is faster or punchier is false. The 15 will be just as fast, just as punchy, and be both louder and able to dip down into lower frequencies. Unless size is an issue, there is no reason to go with a 12. Keep in mind that this assumption is also assuming that they are properly powered in the same type of enclosure.
If both assumption #1
and assumption #2
are correct, the best option is going to be a 15" sub in a ported enclosure.
Now would be a good time to tell me that my assumptions don't hold water.
Should I sell the crown in favor of a plate amp? If yes, what do you recommend?
Do I need some kind of DSP device? The crown has a crossover, but it doesn't do much more than cross the signal over. If so, what do you recommend?
Woofers: I'm torn between the Dayton Reference and the Eminence LAB. Is one superior? Should I be looking at something else because it's clearly better?
My home theater is in my basement. It's an L shaped room with 8' ceilings. The leg of the L with the home theater is about a 17x30. I spend equal time listening to music and watching movies. It's my favorite room in the house. I'm not concerned with how the bass sounds in the other leg of the room, but because it's there, you should also know that the other leg is 15x20.
Thanks in advance for your help.
