Sugestions for building first Subwoofer?

[Scrat]

Hi, i want to try building an Active Subwoofer to go with my current AV Reciever.

Has anyone done this themselves? Can you sugest some good equipment to use, i.e. Sub, Driver, Amp, box design, etc...
I want to try and make it for under AU$1000 if posible (excluding box)



I currently have....

AV Reciever: Harman Kardon - AVR635 (http://www.harmankardon.com/specifications.aspx?Region=EUROPE&Country=AU&Language=ENG&cat=REC&ser=&prod=AVR%20635/230&sType=C) (7.1)
Main Speakers: Dynaudio - Audience 62 (http://www.dynaudiousa.com/products/audience/62/aud62spec.htm) (Floor Standing)
Sub: Hope to have one soon!
Center: Not Yet
Rear's: Not Yet

Any help would be great. Thanks

Parts Express Dayton Reference Series and one of their plate amps. You can get a cabinet from them or you canmake your own. Be advised, the cabinet for a sub is much larger and more difficult to manage. I built a pair and they are outstanding.

How large is your room? Is this going to be used primarily for home theater, music or, some combination of both? How much room do you have for a subwoofer cabinet?

I would also recommend any of Dayton's subwoofers and an adequate plate amp, but given that you're in Australia, you might be better off looking at the Peerless XLS series of subs, which are as good or better than anything Dayton offers (and a bit more expensive) but available all over the world - which should save on shipping substantially.

thanks... so you would say that the Peerless are definatly better? I dont know exactly what i should be looking for in a sub.
I mainly bought my system for listening to music, but would also like to use the sub for movies.
What would be best... a 10" or 12"? The room is about 7m x 5m with alot of windows & doorways coming off it.
Any sugestions on which amp to use? Also is there any free software that i can download to calculate the box size etc... any recommended box designs?

For your first, and possibly last sub,for a while anyway, I would suggest RythmikAudios Servosub (http://rythmikaudio.com/servo_product.htm). On music this thing is remarkable, and it's no slouch at HT either. It should provide you with a pretty flat in-room response down to around 13-15Hz. It is very clean and articulate, and for it's price just can't be beat,IMHO.
If you look here (http://rythmikaudio.com/testimonial.htm) you can read what a few users have to say. Mine is the sonotube based sub under J.B.
Good luck on your search.:cornut:
