Does the Peerless XLS 12 NEED a passive radiator?

The Paulinator · 14th September 2005, 06:35 AM

I'm trying to find a 12" driver that will have high output in an enclosure smaller than 2 cubic feet. Does the Peerless only work in that 1.4 cf box with a radiator?

No it doesn't need a passive radiator at all.

Check the new XXLS line also.

The trouble with XLS range is that the port lengths required are too long for small boxes, hence the PR. I've only worked with the 10" but I assume the same applies: you will either need a PR, or you could use EQ to extend response without a PR since XMAX is plentiful on the XLS

High power input
Low tune
Tiny enclosure
= amazingly long port.

The tiny box requirement arrives from the very low Qes in particular. Its probably nearly impossible to get a decent port that guarantees no chuffing.

I would consider PR or another woofer eg XXLS

I've never even seen the XXLS line. Where can I get them and what is the 12" version capable of enclosure wise?

Ok, I found the XXLS line. It says the DVC version of the 12" has an F3 of 43hz in a 1.75 cf box. I am using the BASH 300 w amp from PE. ( http://www.partsexpress.com/pe/showd...number=300-750) What can I do to EQ a lower F3 out of that driver in that box? I've never gotten much into that.

Why not just make the port external to the box .... seems to work just fine.

1. Because its a waste of space where the port volume approaches the box volume.Ok for some perhaps.

2. Because its long enough to have a pipe resonance in the upper bass.

Should i be looking to any other driver instead to get the smallest enclosure possible with good output?

Nothing wrong with that at all. Passives are a waste of $ in my opinion. If your going to do it, go big enough to have a decent size vent. Passives do not get you anything that you can get with a well designed ported box, except for the small box with low tune of coarse....
