Well, the XLS 10 inch units I have heard using a passive Radiator sound fantastic. I have used an XLS 12 inch in a ported box with excellent results. Pitch recognition is great, bass is tight, extension is really good (as long as you pick the alignment of the box and type to suit the particular model of XLS used!)

I've had great results out of my 10" XLS in a Formatube (Sonatube) design. Current project is to migrate speaker and plate amp into a new 50 litre ported box (under construction) for comparison

I've only briefly compared my 10" XLS + PR with a REL Q150e (500) and it easily outperforms it.

Hi Dave,

Quote:
can you send me the dimensions for that sub box...what size are the holes you cut out in the braces?...do you need to put some batting in the box as well? this is the first sub i'm going to build...
Click the image to open in full size.

All sides are 18mm MDF.
Front and back (red/green): 320x320mm.
Top and Bottom (yellow): 320x356mm.
Sides (blue): 356x356mm
Braces (grey) 320x320mm.

This gives a gross internal volume of 32.7 litres. I estimate between 25-29 litres after bracing, amp and driver displacement.

You must use a wood inserts or t-nuts.

The breathing holes were cut in the braces ad-hoc. I don't remember the sizes of hand.

There is no batting/damping/stuffing material inside.

Were I to do it again, I would double the amount of bracing after seeing how much air this thing moves The tight tolerances on the bracing may not be easy to achieve if this is your first wood working project. You may want to consider doubling up the panel edges.

Some threads/posts that may be of interest:

You have far too much time on your hands -- even got Peerless logos and spider corrugations on that rendering

The spooky thing is that those are the exact same dimensions and layout to the mm that I am using for my new sub (12 inch sealed).

Mine is rinky-dink next to that one. But I do like
the idea of putting the driver and PR both on the front panel and the plate amp on the back. The box can then serve as a stand for satelite speakers or whatever. Interal volume is 28 liters before bracing, speaker and amp displacement. I would like to post a picture, but I can't find one that's small enough for the software here to accept. If you search this group for XLS, I'm sure you can find it.

Mine is made of 1" particle board with a 1" shelf brace between the sub driver on top and the PR on the bottom. The cabinet itself does not rattle -- yet -- but when I turned it up and played a 20 Hz test tone, the PR frame rattled against the box. That bad boy was hoppin! I tightened the bolts down like torquing lug nuts on a car wheel, and it's okay for now.

If I had it to do again, I would get a different plate amp, one with a 24 dB / 8va high pass filter. Parts Express has one that's rated 200 watts, although the 24db rolloff is not advertised. Maybe that's because their expensive amps have only a 12 db rolloff. I'm running the sub through a Richter Scale Serie III.

Finally, 3 or 4 db boost at 20 Hz is not a bad idea. I made a modification to the amp to that effect.

Finally, finally. No, I still haven't finished the raw particle board.
