Which version of the design are you using. I'm trying to locate a set of plans (like the new 18mm ones on the information page) for the version 3 horn. I've tried emailing Brad but he only did a few sketches.

Thanks

i'm using Peter Sylvesters mk 2 designs with 18mm marine ply, have not looked into the mk3 designs, my labs however have turned into the mk4 version, as i have made some slight modifications to the box (wheel and handle and access cover mods) as i'm sure most people have! be wary of the 18mm conversion plans there is a few head scratchin moments in there, measure twice cut once is the name of the game

so are you in the uk then?

Yeah i'm in Nottingham.

Looking at building a couple of LABs and obviously want to use the best sounding design. I read that the version 3 had smoothed out the response a bit. If i can't find any proper plans i'll probably resort to building version 2. What were the mods you did to yours? Anything major?

The modifications i made constisted of throwing away the construction guides after 2 days work and going about it my own way, it is imposible to build a box exactly to the 18mm ply conversion dimentions. Plan your own method of assembly, worked for me.

The main layout of the horn in the box is as the mk 2, i did make my own personal mods like handle placement, wheels, metal access covers etc.

tested one last night with some drum and bass, oh baby.

good to hear someone using the LABs for D&B Smile  Apparently the Tribe of Munt (techno sound system) have been using some LABs for a few months.  Let me know if the LABs will be out gigging as I would love to have a listen to the finished article.

BTW I am using Peter's design.  The V3.0 does smooth the frequency response but seems to allow greater cone excursion so I decided against.

Hi Jeff,

Our system is small but lovely. Our name changes on a fairly regular basis, but at the moment it is called BASSIC.

We do the odd party and pub night in and around Dorchester but we have only recently become system owners prefering to go to Bristol based free parties (were you at steart/ smeatharpe/ leominster/ merthyr?)

Our system is made up of 4 12" coax beymer speakers and will soon include a pair of LabSubs (C-Audio and QSC amps). We also sometimes add a mate's KAM 1850's for a little extra.

I'm sure I have been to a NINE BAR party - are you from the south west too? Will you be doing a post Ashton Court Party?

Maybe see you there. Twisted Evil

We are doing our own party on saturday, check out squatjuice.com

4050's are nice amps i have them to run my mids and 18's. dbx too on the x-over side of things. only problem is it needs upgrading due to 2 bass signalls with separate delay and x over needed to run the labs and 18's, mo money, its seems like a never ending path to the debt free door.

Driver Displacement
« Reply #12 on: July 14, 2004, 12:28:28 am »

Comparative displacement plots are attached (60 volts input), v2.0 top, v3.0 bottom. I wanted to extend the bass response below 30 Hz for home theater use so there is more displacement down low in v3.0. If you high pass filter at 30 hz for pro use the displacements will be about the same. The extra displacement in v3.0 at 45 hz increases ouput to flatten the response some.

Quite funny that you've called you're system Bassic. We used BassiK for our first year, then got togeather with a group who ran nights called Dissident and thats our name now. Names always go around.

Off to a place in Brizzle called burbage joinery, to get a quote on wood cutting for 4 labs on their bling new digital table saw. Don't trust cutting the wood myself!

Anyone used the new 18mm cad and pdf files with the metric conversions yet?

Tom's rig was fat, but with the labs on the floor, you had to get down low to hear them. Guess you need a big room to appreciate.

be interested to know how much they charge for cutting the wood, looking into cnc myself for getting the next batch cut, cutting is the time consuming part of construction, sticking it all togeather dont take that long, well kind of not that long.....

Interesting story

Called up a company called Stage 2 who advertise CND routing in Bristol and sent designs/equired etc. They said "is that the AMerican design what looks like a snale shell?" looks like they've done it before. Trying to work out who else in Bristol is building labs!

waiting to get a pricing. will let you know Jeff, perhaps it'l be cheaper if they've already done it before...

hello chaps !

let us know about these prices for cnc cutting, we want another four asap and we could probably get a decent price if we got them to do a job lot on them.

I was thinking about approaching Imperial college london as i know they have some fat CNC machines there and take on external work. but i am not too sure what to do about supplying DXF files (i think these can be fed straight in to the cnc computer) as we want them to router in the module panels to the side panels and this isnt detailed on the plans on peter's site.

drop me an email at paul@tribeofmunt.org

nice.

Will ask about discount for supplying wood for 4/6/8

The guy said the .dwg files that they had were crap because they didn't describe how the wood is to be cut from each piece of 8x4, just what pieces are required or something like that...

Having routed slots for the module would make things a hell of a lot easier. you'l have to redraw the piece sizes a bit bigger etc i guess. The current 18mm cad files don't have these in them.

Quick question, the baffles are made out of 12mm ply right? then the two sheets are glues togeather. Then did you just glue and screw them to the surrounding flare pieces to make the modules? did you use any special wood glue?

router the baffles into the surrounding module for extra strength, UPVA wood glue, green bottle from B&Q would be fine, just make sure that any gaps are filled with some epoxy or hard setting wood filler. make sure you cut the baffle with the extra mm's to go in to the router channel.

to join the flare to the baffle, glue and then screw.
