Help with Eclipse 8200 response.

[ultimate157 5,000+ posts]

I've got an eclipse 8200. I had it in a 1^3 box, but felt it was too small as the response was lacking. I then built a 4.5cube sealed box.

In both of these boxes the woofer acts as if it is in a bandpass enclosure. Very high peaks in the 35-45hz range, then anything above or below is simply not there.

What am I doing wrong?

SSF is set to 20hz. LPF is set to 80hz.

Most people unfamiliar with this driver don't know that Eclipse says to never use it in a ported enclosure. Why? I don't know. I was told this is an SQ driver, which means it should have nearly the same output through it's response curve, no?

i know alot about that sub..and to tell u the truth...it works well in 4th order bandpass boxes and low tuned ported boxes:up2somet:

I just built a 4.33cu sealed box per recommendation by someone else. Is there a way I can add a port to this box to make it into 3 @ 28?

3/4MDF, inside dimensions are 34.5 x 18.5 x 11.75

Edit: Also I only have a Lanzar Opti pushing around 650-700w rms @ 4 ohms to use.

Forget the enclosure, my RF 2002 (200w rms x 1 @ 4 ohms) is louder than my opti @ supposedly 700w rms @ 4ohm.

5-6 cubic feet ported will work.

the SPL is 82dB and thats why its not as loud. Keep in mind its an SQ driver, but it will sound very different than typical non-linear subwoofers. IF you want just loud bass, the linear motor is probably not for you, go for a non-linear design, sacrifice a bit of distortion but gain back twice the sensitivity.

Thanks for the suggestion, but I found out what was wrong with my system.

My Lanzar amp was acting really weird, no matter the settings I used, SSF or LPF it was outputting very little and sounded like a subwoofer in a Bandpass (very high peak, and steep slopes on either side of the response curve)

It's now back in a 1^3 box, and considering the very good SQ, it gets loud.
