Okay, after a long time roaming these forums, I finally decided to get started on my first DIY subwoofer. So, I registered, and before I start, thought I would ask the experts.
My current audio:
Receiver: Pioneer VSX-1014
Front and Back Speakers: Polk RT55i (-3dB limits: 47Hz - 25 kHz)
Center: CSi3
Room Dimensions:
20 Feet long
15 Feet wide
9 Foot Ceilings
My desire is to build a subwoofer that goes down to about 16Hz with no more than a 3 dB loss. I know that sounds bold, but I figured I may as well aim high. As far as volume, I've never measured dB levels, but I know I don't listen as loud as some. My Pioneer volume rarely gets about -10 dB (and usually, that's only to see how loud I can listen).
I'm no speaker expert, nor do I possess any math skills, so I went with the Adire ready made design. I decided on the Tempest because of the good comments it gets and because it is a very good value. If anyone out there thinks that the Adire Alignment or the Tempest is a mistake, please tell me.
I have several questions, and at the request of the moderators in the faq, I will restrict them all to this thread.
First, for a room of mine's size, how big of an amp will I need? In that same vein, what brands of amps should I be looking at (I think PartsExpress is all that I've really read about)?
Second, the Adire alignment plans don't seem to have any added thickness to the baffle. Is that okay?
Third, and I hope I don't get laughed out of the forums for this one, where in the Adire plans does a plate amp go?
Fourth, do I need to use Adire Flared Ports, or should I use a different brand?
Fifth, I am deciding between MDF and Baltic Birch, which is the preferred material?
Sixth, for all those of you who have built this sub, are there any other surprises/deviations I should expect?
I am very sorry this is so long. Thank you to all those who read this and help. I could only do this with your help. Also, if anyone wants to post a picture of their Adire Alignment subwoofer (especially if they have step by step pictures), I'd love to see it.
