Hi, after having to delay due to Illness I've finally made a start on my rig build. the plan is for 8 x 1850 sub bins and 4 x xtro plus I plan to add some small mid horns and a couple of tweeter boxes for an extra boost to the mid/top. The drivers I'm using for the 1850 bins are void V1000s and the xtro drivers are all as per the plan. The 1st bin to be assembled was built earlier today and here are some 1st pictures, I'll add more as the build continues http://img802.imageshack.us/i/111124145835.png/" rel="nofollow">  http://img830.imageshack.us/i/111124145841.png/" rel="nofollow">  http://img17.imageshack.us/i/111124155442.png/" rel="nofollow">  http://img402.imageshack.us/i/111124155446.png/" rel="nofollow">  I made myself a router template to rebate slots for the horn assembly parts to sit in , I'd had the sections all cut to size by the supplier and had to shape all the angles by hand which has taken up a lot of time but was worth the effort as the 1st bin was put together in an easy 5 hrs. |

Good effort, nothing like using a good old wood plane. Blood sweat and bass.... 8x 1850 and 4x xtros all loaded properly....That system will pump |

I have an FFA10k amp for the sub bins, an FFA6k amp for the xtro bass, crown XTi2000 for mids, a crown xls202 for the tweeters and an NCA digital speaker controller so yeah, pumping is what I'm aiming for :D The FFA6K amp runs 4 channels at 1.5k per channel at 4 ohms so should be ideal for xtro bass section and the 10k will run 4 subs per channel at 2 ohms with a max peak of 1.25k per bin, from my experience this shouldn't be any danger to the V18 1000 drivers but if I'm wrong someone please tell me now so I can set the limiter. My only real concern is the mids being underpowered hence the plan for extra mid horns and tweeter boxes.

i run an 1850 and xtro stack and believe me run correctly i dont think you will need any of the extra mid/hi you previously mentioned. the xtros are very powerful cabs. they took me by surprise we have two on top of 4 1850's currently and we cant even turn the xtros rigt up and thats with our crossover output volumes as low as they can go! ------------- joints and joinery |

Ive just sold my old rig and was planning on making 8 1850's like yourself, how much has this project cost you in terms of ply?? how many sheets is it taking you per bin??
thanks

My friend and I made the template for the xtros yesterday, the 10mm scrap ply I used wasn't exactly ideal but a bit of glue worked into the edges on the corners and any weak spots to harden it seems to have sorted it out. We will be using it for making the cab sides on our next workday. As for the amount of ply needed for the 1850's, I think it worked out to less than 6 or 7 sheets for 8 cabs, it's a while since I bought it and I cant remember for sure, with some creative cutting it may even be managed with 5-6 sheets. I bought marine ply as beech was not available locally. I already have the tops,bottoms,backs & sides for the xtros but still need to get the internal horn sections cut to size now I have the correct measurements to fit my plan, 25 seperate sections is gonna be a lot of plane work  http://img267.imageshack.us/i/template1w.png/" rel="nofollow">  Template and tools used. http://img688.imageshack.us/i/template3u.png/" rel="nofollow">  And my work bench http://img833.imageshack.us/i/template5.png/" rel="nofollow">  You can also see some of the 1850 template behind. Not a great job but it worked and I learned a lot making it so the xtro template was a lot easier. I'll add some more pics next week, hopefully.. |

| I would be very grateful if those of you who have mentioned having an xtro/1850 rig would post your delay settings for me so I have a somewhere to start without having to tax my own brain too much working it out. I have the settings for a xtro/punisher rig but they wont help much as the punisher horn looks much longer than the 1850. |

Yes we used Tee-Nuts and M8 pan head screws, it's worth buying Allen key bolts if you can find some long enough as getting to them when fitting can be a struggle, you need a minimum of 40mm long, I found 45mm the best size. Work has been progressing on my xtros and I shall add some more pictures very soon, I almost have everything ready to start assembling the 1st pair.

As Promised, some pics of the progress we are making, This is the 1st set of parts to be ready for assembly with a 2nd set not far behind and another 2 sets about half ready. We should be assembling the 1st cab in the next week or so, I'll try and take a couple of pics as we put it together. If the prep work has been done well the assembly should be fairly easy, I hope ;) http://img823.imageshack.us/i/121204213217.png/" rel="nofollow">  Nice roundover on the edges, same tool was used on all the edges of the 6 x 1850 cabs as well, always worth doing, the results are so rewarding. http://img217.imageshack.us/i/121204215259.png/" rel="nofollow">  http://img9.imageshack.us/i/121204215335.png/" rel="nofollow">  http://img24.imageshack.us/i/121204215347.png/" rel="nofollow">  http://img705.imageshack.us/i/121204215843.png/" rel="nofollow">

Birch you mean? I always cry when I see people building from anything else than the best birch! Why? 1. It's just not good enough! Sound is bad with good drivers & bad ply. 2. Better use second hand crap drivers for a start to save money, the driver can be upgraded, ply can't. 3. Your time should not worth be worth using less than the best, think of how long time this takes to produce compared to a factory new speaker. So your speaker is worth more than Funktion one in time! I don't know what your wages are, but think about it! Calculate, it's not worth saving on ply! 4. You're gonna kill me for this: I would use cnc companies, they can deliver pre cut flatpacks at a price that matches the price of ply in the market! Check your companies around, check Poland & east EU. |

I am rather interested in the comparison between the Void & PD drivers. Aren't these usually loaded with PD? perhaps You will give an opinion on the differences |

1) best birch is expensive, and i would like to see if in a blind test you could hear the difference between 7 ply, and finest 13lam providing they are braced well. 2)I wouldn’t use crap drivers in an 1850, would probably end up damaging them. 3)see 1 4)this is a DIY forum. |

Interresting suggestion with that blind test! I almost tried that actually! I felt that I could definitely hear that fir cabs are more boomy comparing one to one. But bracing will help as you suggest. Actually I prefer chipboard above mdf above fir, fir is the worst shit sorry! I know chipboard & mdf is heavy, but if you want something light with a comparable sound use birch! Fir is very soft, yuck I really hate that shit, but there's certain types of stronger "in-between" types of ply that I don't know the name of in english. The point is that it just makes me sad to see people use good skills to build fir cabs, I think everyone deserves better! And NOTE THIS: You're going to loose all the money saved when selling the cabs again, I NEVER buy fir cabs no matter how well they're built and a lot of people won't. Some people don't even say that they sell cabs in fir or pretend that they don't know, because they know it will put the price down. Just do quality DIY, two birchboxes with quality drivers is better that four in fir with budget drivers!-) |

I think I made my opinion on this subject pretty clear. I in respect of peoples fine work I think fir ply is not good enough for it. Fir cabs are not that strong & hard. They resonate more like a drum when u hit em They're easy to scratch They have an uneven surface They'll give you a lower sale price |

Years ago, American cabs had a really bad reputation, which is one of the reasons why so many PA companies had their JBL cabs built here. I remember seeing some Altec "Voice of the Theatre" A7 cabs which just fell apart. It seemed that, unlike now, Americans couldn't buy Russian Birch, so they were stuck with Canadian Douglas Fir, which is technically a soft wood. Douglas For shouldn't be confused with Far eastern or Lauan Ply which be similar in appearance.

Been said before, Finnish is regarded as the best, and the most expensive. Great for production because it is generally softer than Baltic or Russian Birch, and is easier on the cutters. When we were building the TMS range for Turbosound, it was all Finnish although a little thinner. Max was 15mm apart from the 24 which was 24mm. the TSE range used Russian. It could be argued that in spite of being classed as a better ply, Baltic or Russian could have the edge on sound because it's harder and therefore a little less resonant perhaps.

I remember seeing both JBL & Altec cabs in the early seventies and was not impressed with ply used which in both cases looked like it had sat on a building site in the rain for a few months. Both sets of Altec A7s looked worse than the JBLs (one was painted grey the other varnished or waxed) and it was obvious that both were delaminating and not only at the edges, but the JBLs were in a truly dreadful state and either hadn't been glued/screwed together properly or the whole box was de-laminating but the evidence wasn't yet visible from the outside except that the cabs were wobbly! Also, the JBLs seemed to be made of very thin wood - possibly only 12mm - and didn't look like they would last for any time. Still, major large scale touring was pretty much in its infancy - most bands in the UK were still using WEM systems and Martin et al had just started but they were far superior build wise than the American stuff I saw - I wonder how many company made JBL/Altec cabs from that era are still touring today (I know lots of them were installs, due to my earlier point, but I have seen many pics of old cabs taken from clubs/theatres etc that had also began to fall apart. Many old cabs still around are probably home made as plans were readily available, and probably used better quality materials than the manufacturers themselves). ------------- For sidefills, can we have two enormous things of a type that might be venerated as Gods by the inhabitants of Easter Island, capable of reaching volumes that would make Beelzebub soil his pants. |

I concur with TR on this often US Manufacturers no choice as import of "Russian Birch" was actually banned in the USA IIRC not allowed so they had Poplar or Furniture grade Ply a bit like our "Shutterring" Some like JbL had there cabs made in Finland for the European market in the past there was a similar issue in Japan also they had a similar supply constraint and some did what JBL did and supply Components for systems built in Euriope I do not think there still exists such issue around the Globe any more. "Finnish" or "Baltic" Birchply is just a commodity now available on a global scale |
