Hi,
This is an interesting model for me, but I have to change:
  • BMS 4550 to BMS 4555, because second one is available. The features look like completely the same, that's why it doesn't matter, I think.
  • RCF HF64 to BMS 2236, same reason as previous. First one is complicated to buy for me, but possible.
This horn is a little bit strange for mount, because this is larger than rcf hf64. Width: 498mm (mounting plate looks little bit larger than 500mm on the plan - it fits), height: 348mm - too large. May I resize a bit this part or I have to use rcf hf64 every way?
I have to built a crossover also. Which frequency is recommended?

Hi all,
very interested in this design, has anyone made a 15 inch version or could anyone give me the adjusted measurements to make a 15 inch version.

takes just over 1 sheet, you can get 2 out of 3 sheets. i used 18mm for the main box frame and 12mm MDF for the baffles. the horn is available (in the uk) From Blue Aran

having never build one I can't tell you how much material one takes. and under question of cutting offbehind the bafflenot sure what your reference to

Hi,
Just wondering how many sheets of 2440x1220 will be needed for this project and if 18mm sheets are being used?

Also where can i purchase the horn moulding?

Edit: Also wondering if the empty space at the back of the horn, behind the baffle, could be cut out?

I believe that the chamber behind the LF speaker is 15L

sorry, and what about the wood thickness? is the same thickness for all? im thinking about use 18mm except for the A and B pieces, what u think about use 15mm for all instead of 18mm?

seeing the photos it looks like is 15mm all...
Thanks!

yeh, kinda cant rebuild. i need them ready for NYE. im going to just finish the horn side and ill rebuild them after. im sure a slight loss around the 100hz wont be noticable as ive upgraded from a reflex cab which simulated 6db less on hornresp than the MT130 anyway.

also, on that note, if they sound good open, ill just leave them that way.

ill post up with pics and my experience soon.

it would have to be a damn tight seal if you did...... for what its worth, just re-cut the bits you fecked up and build it properly. you'll kick yourself if you dont!

to be truly honest, im not sure what ive done, the plans i printed werent clear, so it was likely a wrong number ive read..

edit*
i read the 136mm to be the rear side of the baffle, and ive just reopened the file and discovered that i need to move the baffle forwards. problem there is i have already glued the horn section in place.... dammit.

my biggest Q is wether or not the woofer will act normally with the magnet outside the chamber. (good for cooling tho) as its vented coil. i was thinking i could cut a neat hole, and put a seal around the magnet so the chamber stays sealed.

...so if my maths is right the very front of the baffle should be 18mm(slot baffle) +10mm(gasket baffle)+ 136mm(internal chamber) +18mm(back panel) from the back of the bace panel of the box.



unless your building the 10" version and trying to stick 12" drivers in it....

mini-mad replied the topic: #20995 5 years 7 months ago
...are these are all the correct dimensions?

just asking as there should be about 13.6cm of depth in that chamber and the delta12 is only 13.6cm deep, the second layer of the baffle that keeps the cone from hitting the 1st slot baffle should only be 1cm deep too.

if it was all made to plan the back of the magnet should be flat against the back of the chamber.

Hi guys, im in the middle of building a pair of these and have discovered my Delta12 drivers are too deep so don't fit in the rear chamber.

will I be ok to create a hole in the back panel for the magnet to poke out of as long as its sealed?

There fab cabs. A bit big for the output vs say my JBL 4825s but they sound brilliant for all kinds of dance music. Only used them on a band once or twice and thought that they there a bit to kicky.

Hey

Can I ask how you got on with these? They're always a design that I've had a bit of an interest in , but only a few people seem to have built them (outside of Marc O's french forum) and always been kind of mixed reviews.

hey

yeah measure the delay of your subs and tops each just at the crossover frequency, and then delay so they match at that frequency point.
