I have read good reviews about these speakers and amp

.
jostenmeatm, building my own sub sounds fun. I have a small home biz (modifying / repairing Xbox 360s and other small electronics) so I think I have the tools needed to put one together. However, I just don't have the time right now. Maybe when exams are over or during the holidays I can look into it more. Would you say that I would save 50% (after everything is finished) if I built my own sub vs. buying a new one (the same kind)? I don't mind big subs, the bigger the better - I want it to shake my chest
This is a great forum and I will be reading through here some more.
Tough question. It depends on:
- if the money goes towards only performance, or smaller size (you don't care), or nice finish.
-the budget we are talking about. To a certain point, the more you spend, the more value you might get with DIY (it's probably not worth DIY with a very puny budget).
Therefore, if you are ok with ugly or no finish, a monstrosity of a subwoofer, the performance savings are probably more like in the thousands of dollars, or 500% or something. Make sense maybe?
For instance, check out the Tuba HT by Fitzmaurice (plans cost $15). It's big, it's efficient, it'll rattle your rib cage with only modest power, it'll break your windows with only moderate power, and it'll be super clean doing it all. It doesn't have the lowest of the lowest extension, but chasing that is dubious according to many (I wanted it, but mine is freaking 5' wide and 280lbs; yes, I took advil).
annunaki loves helping people design subs, if he has the time. TLS Guy of course knows his shiznit as well.
Oh, if you do want something custom by a pro, or a good value for you in CA, Funky Waves I think it's called is supposed to be good. billy p (another Canuck) raves about it.
