New Sub

Atmosphere · 09-30-2009, 07:17 PM

So I just picked this up:

It works, though I'm not completely sure of the specifications (I bought it from two girls, they didn't know anything about it). It was just too good to pass up for the price. Right now I'm just cleaning it up a bit, it's clearly been sitting around for quite some time but physically it's in good condition.

What do you think it's worth?

I would say about $60 tops.

Thats a prefabbed bandpass from Best Buy with a RF sub also from best buy.

The sub isnt horrible by any means, but not to spectacular.

The box, well thats a piece of dung.

Damn, I was hoping it would be nicer than that lol. Could you recommend an amp to drive it?

Thanks for the input.

You will have to pull the subwoofer out of the box and write down the part number of the sub. There is three different subs this may be.

If your sub is an 8 Ohm model you got shafted.

So your going to need a 400 WRMS x 1 @ 4 Ohms to drive it.

800 WRMS x 1 @ 2 Ohms

16000 WRMS x 1 @ 1 Ohms

To drive it.

Sell that thing off.

for a RF that really isn't a very good sub at all. 8 ohm is messed up, why would there even be a sub at 8 ohm. its just that much harder to find a good amp to power it.

Atmosphere · 10-01-2009, 07:25 PM

Sounds good, thanks for the help.

I'm curious though, what makes the box a bad box?

Ryan from Ohio · 10-01-2009, 08:59 PM

Its bandpass.

and how's that for nerding it up?

Atmosphere · 10-01-2009, 09:34 PM

Perfect lol.

That sucks though, I thought it looked cool. I was gonna throw in some LEDs and everything. Haha

Hey now. I got a JBL Bandpass enclosure for 100 bucks off a guy. 300wrms. And I love the sound, it gives me the little bump i was looking for, without the hassle of building a big god-awful box.

I have a JBL sub in my home system, had it since 1978. Still rockin' !!

I haven't heard the new stuff, though. You used to be able to get the raw drivers from JBL, don't think you can now.

JLw7123 · 10-02-2009, 04:53 PM

JBL is a great sub no distortion really clear bass

well they are no as good as RE audio and JL but they are good
i am getting 3 RE subs

Ryan from Ohio · 10-02-2009, 11:34 PM

Your first statement was very noobish.

This latest is very broad. RE does make some good subs though.

jayson_waltz · 10-03-2009, 01:49 AM

jbl is for people that want pure loudness and not a lot of quality of sound. and thats only if you get their expensive stuff.
