Guest Posted December 24, 2017 Share Posted December 24, 2017 (edited) Carried on from the DIY Thread. @Upfront @davewantsmoore, @BioBrian @soundbyte @Auracle Scope of project is to house 2 pairs of 21" AP neo SD1800w for in field Professional use, but will live in a large room for most of their lives.. Aiming for efficiency of +100dB (for the first watt) which the WinISD simulator seems to agree with same as the Factory Specifications. Idea is to build a better match to the JBL Cinema 3 way horns than the 18" Eminence Magnum Enclosures (chasing efficiency) +4dB actually for same power or more. Will be an interesting project, will pop up some photos, simulator results and real time testing when finally at that stage. Have the materials on the bench, time to start marking out and crack the first can for the day.

Guest Posted December 24, 2017 Share Posted December 24, 2017 Always reward the first cut of many Simple as a straight edge, couple of clamps and an 18v battery saw to cut all the parts, no cnc or saw bench. Vacuum up as I go. Router work done as far away from the house as the cord will get me. Link to comment Share on other sites More sharing options...

They probably won't be going for NYE, but I might get a good run and not stuff up another sheet. (would be a liar if I said I never made a mistake) Routing next and laminate together the pieces for each double baffle being 36mm thick. Link to comment Share on other sites More sharing options...

I despise the mdf but luckily the rest of the enclosures are in ply and solid timber, not so bad. Trying to decide weather the boxes get a black carpet job on the baffle front, or vinyl. Baffle framed with timber batten stained black clear coat satin. Satin black texture paint finish. Speaker grill fits inside the baffle timber frame.

Guest Posted December 25, 2017 Share Posted December 25, 2017 (edited) Getting things done, seems slow but on the other hand, if it takes all day, let it. Cutting the vent holes, little trick is to transpose the cuts to the second sheet, saves a lot of time re marking. The go is to clamp exactly 2 pieces together and plunge cut into the second sheet a mm or 2 Trying to work within 1mm, is working nicely. To get 1 front baffle laminated today would be enough amongst everything else. PS those Ryobi 1800w soft start variable speed routers for 147 dollars are a bargain EDIT first blunder for the day is, having to do some cuts for the ports again as there wasn't allowance made for the 18mm port wall thickness, I considered it practice thankfully no more sheets lost today, yet.

Guest Posted December 25, 2017 Share Posted December 25, 2017 Getting there, have no doubt in the mind the job as a whole will be 40 hours. At least it's progressing well today and very accurate as in you could swap or invert the sheets and still come out fine, in the 1 mm tolerance tricky but very do able. Builders bog used very sparingly on this. Now for the inner baffles fronts are done might even get to glue 1 together today which would get me cutting the boxes tomorrow. (rather do this than paint weatherboards) Link to comment Share on other sites More sharing options...
Guest Posted December 25, 2017 Share Posted December 25, 2017 balance of job using 25mm pine ply and hardwood bracing MDF makes a good complex baffle, but that is where it ends, dusty stuff, cough. Link to comment Share on other sites More sharing options...
Guest Posted December 25, 2017 Share Posted December 25, 2017 (edited) @Upfront Black indoor/outdoor carpet in the black and grey or black leather look vinyl for the baffle faces ? any other ideas other than paint or veneer ? Anyone ? these are to look smart and tight out as well as inside. Keen on the vinyl actually as it would look trick with the hardwood trims.

soundbyte Posted December 25, 2017 Share Posted December 25, 2017 Cannot help with the finish as I prefer a raw wood finish. You will need something though. Do you think it needs to be like the JBL's, or something completely different? Leather look vinyl might be the go as it should look like the JBL's.
