I didn't read the thread, so I hope I don't repeat something already said.. but it really just comes down to what you plan on doing with it and what type of sound you're looking for. I've owned both and they've both got their advantages.
SA8 is going to handle power better and sound pretty good doing it. Epic is lesser in the handling area but is going to sound much better. You could do some proper design work and they'd both perform identical. My choice, however.. for flexibility reasons i'd go with the SA. The Epics just don't get loud like the Epics.
Its purely based on what you plan on doing and what your goal is.. but due to the overwhelmingly good customer service and warranties from Sundown plus the performance aspect (custom tooled baskets, cooling, etc) i'd go with Sundown. How many times has TC gone under now? ..that's coming from a die hard TC lover.
Thanks for the reply. In one of your sentences, you said that the Epics just dont get loud like the Epics... Which did you mean? The Epics dont get get loud like the SA's or the SA's dont get loud like the Epics?
What I am trying to achieve, is to get that "OMG, those are 8's!? Those are loud!" Obviously I want some sound quality. I want a lower tuning so I can get the 8's to dive down low. I listen to 70% rap and 30% rock like Linkin Park, Breaking Benjamin, RED, etc....
I have plenty of power on tap. I have an Audiopipe 3000D. And to be honest, I am extremely suprised and impressed with this amplifier. Its a bit power hungry unfortunately, but a great amp and thats taking out the extremely low price factol I'd prefer to run 4 subs instead of 3, mainly because the amp is two amps internally bridged so running 3 amps would be a bit of a task and would have to be wired internally and would have to be bridged and would have to have a final ohm load of 2 ohms or higher since it would be bridged.
I have been told that the Epic 8's and 10's can be run at 600wrms. They are rated for 500wrms. Not sure if that is ported or sealed. Of course, running ported will lower your power handling. The SA-8's are rated for what? 750wrms?
3 Epic 8's or 10's @ 600wrms = 1800wrms
4 Epic 8's or 10's @ 750wrms = 2400wrms
3 SA-8's @ 750wrms = 2250wrms
4 SA-8's @ 750wrms = 3000wrms
Now that rated at 2 ohms, which I obviously wouldnt get.
If I run three 2 DVC subs, I would either get 1.34 ohms or 3 ohms
If I run three 4 DVC subs, I would get 2.67 ohms
If I run four 2 DVC subs, I would get 1 or 4 ohm load
If I run four 4 DVC subs, I would get 2 ohm load
So I need to run either
Three 4 DVC subs @ 2.67 ohms
or
Four 4 DVC subs for a 2 ohm load
Obviously Four 4 DVC subs is the most optimal with box rise.
