need help with music sub

epalla · 30th June 2006, 01:02 AM

I'm building a sub to put some serious low end in to match my Selenium 15CO1Ps. I need it basically to give me the obnoxious level of bass required for parties - I know it's not the most musical thing around, but it's what we need for the system.

So, basically we're talking about moving a lot of air, so I think a 15" sub is the best option for me, besides maybe a complicated labhorn setup, but I don't really want to go down that path.

Catch is - I already have amplification in the form of a Crown XLS-202 - good for about 500w @ 8 ohms. I don't want to get any clipping while the sub is driving hard, so I don't want to get a driver too far past that power handling.

My budget for a driver is around $200, and a few people have already suggested looking into Adire's Tempests, which look great (if a bit more HT than music oriented). I've been looking at Selenium drivers too to match the rest of my set, specifically the 15SW2P-SLF

do you think that'll treat me right? Or am I way off track here?

I would probably go with a 15" pro driver tuned to around 40Hz or so.

so basically, I'm on the right track.

well youll have to do some modelling, but thats a pretty extreme looking driver you picked out.

ever think of a horn? would keeping the sub corner loaded be an option?

epalla · 30th June 2006, 10:22 PM

I have actually thought of a horn, I was wondering if someone was going to bring it up.

They can produce some pretty impressive output with smaller drivers. The tradeoff is in the size and complexity of the cabinet design right? Eminence sells a 12" sub designed to be used in a horn configuration that I was very curious about, but I don't have much experience with horns, especially not on subs.

Would I be looking at a better sounding sub if I went that route?

it says it's optimized for horn loaded enclosures. My original plan was just a normal ported front-firing box. I'm not sure on the size or venting yet but it depends on the driver, clearly.

I am pretty impressed with the numbers on that monster though. BIG SPL mostly. It's cheaper than the Selenium driver too. Maybe bumping it up another notch to 18" is the right way to go.

What about something like this.Loud as hell for music.It was fairly cheap to build and its perfect from 40hz to 110 hz that I use it for.

wow! looks like one of the tuba family. Have you got any measurements?

Personally, with that amp I'd be looking at finding a pair of 4 ohm drivers for it, 15" or preferably 18" (one per channel)
