I really like the look of this plan and think its something that i could build. I was thinking of using a different driver as i can get a good deal on the v18 from a friend. would this driver work with the current plan or would i need to change the chamber volume? i would also like to know if anyone has thought of extending the horn using a separate flared section like some home theatre buff did with the lab sub.
Peace

This Selenium box design reminds me of the Cerwin Vega SL36 .

Be carefull as there are still a lot of venues with narrow entrance doors and once you get over 750mm(plus wheels) you will not be able to get your cabinets into the building---this tends to be the older venues as due to current health and safety legislation,doorways in modern buildings are a lot wider to accomodate wheelchairs etc.

I had a close look at this plan a long time ago. And the people I spoke to said the horn was to short to get any useful depth/throw, especially with 18" drivers.
Someone, some where, on some forum once wrote "Longest horn always wins". Quake MSE 118/Lab seem to be good examples of this. |

so the two pieces come away from each other and can be strapped together when needed... something like this would allow to use the box without the horn extender if for some reason you didnt want too.
its still a dual 18 cab and is still 1m high as per plans.

heatrow, I would vote for the second plan , the first one expands too fast in the final stage

thanks nexus!!! i saw them in the link you posted on another thread and they just jumped off the page at me. i like the simple design and the way its such a small cab but uses the maximum horn length possible. i will start building soon, i want to build 4 cabs loaded with 8 void v18's. do you think i will need to modiy the plan at all? my plan is to build the cabs as they plans out of birch and build some trial extenders out of 18 mm mdf... i have thought of a mad plan using a huge 5 to 6 m horn. i dont think i'll use cad but i'll scan a drawing in to show u what i'm thinking... this plans just seems like what i want as its not to big, uses 2 18's and is manageable. the labs just seem like there a bridge too far |
