Correct, we just glue with PL Premium 3X and then clamp for 24 hours.  Wood glues, when used correctly, are stronger than the actual wood.  I’ve tested this by gluing two parts together at a right-angle and then swinging the wood against a tree, the wood broke but the joint did not.  We tested the 8X and did not like it as much though I think cost had a lot to do with it since we have to worry about cost in a production instance that DIYers don’t have to worry about.  But I’m willing to pay more for better performance, but we liked the PL 3X better.

Here is a video showing the construction of our Mariana 18S subwoofer.  We put it together and use 2 ratchet straps to go around the sides and then 8 parallel clamps for front to back.  Like I said, we let the glue dry for 24 hours and the enclosure is solid.  The corners are 2” mdf corners, everything else is 18mm Baltic Birch plywood.

 

Thanks a lot  Dgage for your fast reply,  I will go for the 3X ,   I will follow your professional experience!  Thanks Again

I use PL Premium 3X for my commercial subs and don’t use fasteners for our standard offerings.  Not sure what the equivalent that would be on your side of the pond but we’ve tried quite a few types and PL Premium 3X is the one we like the best by far.  We used to use Loctite Heavy Duty but we had a couple bad tubes I think so kicked that stuff to the curb.

I believe most use true Baltic Birch plywood, which is significantly better than standard plywood (13 void-free plys in 18mm vs inconsistent layering).  The true Baltic Birch I get for my business is from Russia/Ukraine and less than $50 USD in bulk for 1520mmx1520mmx18mm sheets.  This is definitely the best plywood for building speaker and sub enclosures.  You could use MDF but I don’t like it, it’s heavy and won’t hold up if dropped and doesn’t hold screws well.

If I understand right,

1.-  do you use PL Premium 3X from loctite  and don't  use screws   even for subs?

2.- Is the Loctite PL Premium 8x Fast Grab,  Best than the 3X  you recommended? 

Thanks,

Jay Michael. One step ahead, Nice.😉

Yeah Cnc work can be pricy.  I had my guy do only the tricky stuff, parts with angles holes etc.  I cut everything else that was basic with a table saw. Cost me 400ish Cnc labour for 4 cabinets worth

2 Skrams.

Smaller and easier to move with 1 person. Larger vent area, even greater tuning options, larger air volume for slightly increased low end. 2 Skrams should be offer a bit higher performance than a single Skhorn assuming that both are using the same drivers.

OK. I'm Now decided to build the amazing SKRAM. Like always you're so helpful Ricci,  

Many thanks Mr. designer speaker genius. 😉

Yes I have the skrams setup as left/right stereo and summed both L/R signal to Skhorn. 

Comparison wise... 

I prefer two skrams to one Skhorn. If we're comparing one to one and budget/size/space is not an issue, no comparison Skhorn wins IMHO. 

 

 

 

Hi, (My first lenguaje is Spanish),  So if I understand right:  If not an issue  size, weight, space  do you prefer 1 Skhorn vs 2 skrams?   Why?

Thanks.😃
