I recieved the MDF panels for my S150 sub yesterday, did a quick test fit and then it was straight out the back to glue it all together. Will post updates as things move along.

Now THAT'S a solid chunk of wood. How're you planning to finish the box, Cal?

Sure is!! That lump weighs more than I do. The plan is to router the edges and paint it in an off white to match my C6, M6 and M5's. C6 M6's M5's These were actually finished but need to be re-done due to a couple of slices in the face from a stanley knife when clearing out the excess paint from the tweeter recess.

I really like the white look. You will have to post a pic of the completed setup when it is done. Excellent finishing on them so far too :)

On to the sand, putty, sand, putty stage... So far just using auto bog for the larger gaps around the edge. Actual gaps won't take a stanley blade so we're talking fairly fine.

Ok so I've done a heap of sanding over the last couple of days. I'm at the point that I need to router the edges but don't have one available so I've moved on to using a bitumenised paint to cover the inside. Should help dampen out the cabinet a little :)

Houston, we may have a problem.. Finally got hold of a router and did the edges. Now after more sanding this crack line is appearing in the middle of both the top and bottom panels. Whilst sanding there is a funky 'brrrrrrrup' noise generated on these two panels. Now I'm worried how this is going to affect performance when finished?

I've decided to continue anyway. Some pics of the base prep with Series 500 spray putty.3

r.e. the split...
MDF sometimes does that just because, it seems to be a manufacturing thing. Overly enthusiastic clamping sometimes exacerbates it. I wouldn't worry about it, really, though filling it with glue or a liquid putty would not be a bad idea, the vibrations from a speaker might cause it to 'flap' like you heard from the sander. I've only ever had sheets split like that on shelves and the like, so I'm not as certain about its effect on speakers. :)

Ok so finally had enough of playing with putty this weekend. Here's the result of the final sanding. Done by hand with 800 grit paper, the undercoat is silky smooooooth :) Of course, this means that now I get to spray them :D First coat.

Finally finished! Well except for hiding the wiring and getting the M5's mounted up correctly.

Wow... That S150 is... Big. I had no idea they were that chunky.
I bet that one rattles the house. :D
I really like the finish - wonderful! Did you use a spraygun?

Very nice!! Now I need some advice and pointers :)
What are the steps you took from start till it completes? Was it normal wood putty paste? If you could please list out the actual products you use (eg. paint) as well as the sandpaper grit rating (eg. which one to use etc), that would be great. I am very tempted to remove the veneer off mine and paint it.
Was it hard to use a router? Might have to invest in one.
Thanks :d/

Wow Cal! They Look shmik!
Was the inside paint on the S150 tar paint or an official sound deadener paint?
Did you paint the inside of the other boxes with the tar paint?
Just interested because i don't know if I should paint the inside of all my boxes?
If mine look half as good as them I would be happy.
Great Job

Thanks for the comments guys! Glad you like them. Yeah they sound awesome :d/ Yorik, Yep grabbed a cheap Scorpion spray gun from Repco for about $35 on special. http://www.austechindustries.com.au/content/spray.pdf <-- It's the SX60-2 model in the .pdf Dead simple to use, just remember to wash it out thoroughly even in between coats. I used an Enamel paint so plenty of Mineral Turps. moomoocow, The base putty for all the cracks and edges was Kahfill Auto bog  after that the sides of the box were given 3 coats of Series 500 Spray Putty (the blue coating in the pics above).  For all the early sanding I used 80, 120 & 180 grit discs on an orbital sander. That smoothed the box out enough to start filling cracks with the Kahfill. The blue putty was sanded back with 180 & 400 grit discs (which is a PITA as you have to change them out almost instantly as the disc 'fills' and gets smoothed over). Final coat before paint was done with the 800 grit wet and dry. Edges were hand sanded with a foam block because it's soft and doesn't do too much damage. Once painted then I used the 400 grit discs and 800 grit wet and dry to scuff back the surface between coats. There's a write up on the old forum with some more info that I'll try to re-post here. The router is again a really simple tool to use, just have to respect it or it will bite you. devo, The tar inside is Ormonoid Bitumenised paint.  Not official sound deadener although they do list that as one of it's properties on the can. I haven't used it in the other speakers that I made from LSK but I have used it on custom boxes I've made for the exGF's hatch back with success. No pics of that I'm afraid and I'm not ringing her for one either lol :D HTH! Cal

I'm looking at spray painting my M4 kit, and have been looking around for the putty/primer products you've been using - but can't find any of them. Super Cheap Auto has the Septone range that looks ok....... I was thinking of filling large gaps with the Car Fix Body Filler http://www.septone.com.au/detail.asp?item_cat=&item_number=116&page_num=2 which is a 2-part styrene product And spray priming/puttying in one step with Aerosol Primer Filler http://www.septone.com.au/detail.asp?item_cat=&item_number=227&page_num=1Does this sound OK? And for paint, I haven't been able to find anything but White Night either, but I'll worry about that a little later......
