Hi Guys,
I am planning to make a sub. It will be my first attempt at DIY, rather semi DIY as I personally probably wont be doing much:lol:, just buy the driver and the plate amp and get the cabinet made by a carpenter.
A friend of mine will get the plate amp and the woofer from the US. My budget is around 700-800$ including shipping in US. I can get a lot of good subs like vtf3 etc in this budget, so I should be able to make a much better sub than that with this much of money.
The sub should be musical, but should also have good SPL for movies. Dual subs are ruled out, though I can have 2 drivers (e.g. shiva 12) in the same sub, does that need 2 channel amp, separate amp is ruled out, passive radiator should be ok. 110 volt amp is ruled out.
Listening area
The main listening area is 19.5 x 18.5 x 10.5
3787 cubic feet. The system is kept along the 18.5 ft wall. The listening positions is about 12 ft.
But the Dining and open kitchen is attached to it, and the total area is 31.5 ft x 18.5 x 10.5 = 6118 cubic feet
So I guess I should consider the room to be 6118 cubic feet for subwoofer purchase purpose, right? Let me know if a rough diagram of the room will help in suggesting a sub and I will post it.
Usage
50% music and 50% movies
I mainly listen to classic rock, blues, heavy metal, jazz, classical music etc. Watch all sorts of movies from classics to action, scifi etc.
Current setup
Yamaha RX-V663 AVR, marantz cd6000 OSE cd player, B&W 602 S2 for mains, LCR 600S3 center channel, B&W rock solid for surrounds, HTPC with M-Audio revolution 7.1 sound card.
I dont know much about DIY, so I will be needing a lot of help from you guys.
Size Max size allowed (read WAF)
W 22, D 25, H = 30
As bigger subs are better, I would like to go for the max size possible.
I would prefer a 15 or 18 driver due to the large room size. How good is a 12 with a PR. Is it better than a 15/18. How about a dual 12.
Since the room is huge, I guess I will have to go for a ported design. I want the sub to be down firing as it will be relatively kid proof. I dont know much about the designing the cabinet, so I will need help from you guys in that too, but first I need to identify the woofer and amp that I want.
I saw the following good ones on the web, please feel free to suggest out of this list if you have a good one in mind.

3. Amp wattage? Is 500w enough
4. BASH amp vs non bash amp. Pros and cons.
5. whats the best utilization of money, split between amp and driver.
6. What else can I get from US that will help. Flared port? Wires, feet. What size flared port.
7. what else do I need apart from driver, cabinet and amp.
8. what price is 1 MDF in India. If its too expensive, what are the alternatives. Can real wood like sheesham be used for this. What about plywood, do u get 1. Which is better. Prices?
9. Can I use wheels for feet. The sub will be down firing.
10. Does the driver comes with the nuts bolts etc for mounting.
11. why most of the people try to avoid nails and use only glue. What about nails along with glue. What bout nuts instead of nails.
12. what specs do I need to look in a driver and the amp.
13. any good looking designs for the cab you have. i shoud be able to use it as a side table.
14. the t/s parameters, can some one tell me which ones should be lower/higher the better.
