Good morning all! Seeing as I'm likely to have a bit more time on my hands over the coming months, I thought I might start doing some research into a suitable (home-made) cabinet for this driver! Note: I have searched the forum. There is some discussion about this series of driver. From what I can see, forum members recommend somewhere between 40-60ltr box capacity, sealed for a reasonably low cutoff frequency. I am not looking for the lowest of lows, so I'm not going to port it. I already have my bass cabinet and plan to make something in the future to supersede my current box. Here's what I have: Bass - Fane 15" 600XB, on bass duties, 40-100hz (ish) (Cabinet to be update in the future) Mid - Fane 12-200LT - Currently unboxed, waiting to be used. Aiming for 90/100hz up Top - B&C DE400TN - 2.5khz and up. I am currently using a home-brew mid/top section. Recycled from an old ping-pong table. It's rough and ready. Not very well sealed etc. More of an exercise in terrible carpentry skills and recycling Hi-Fi components. Looks great to the uneducated eye, but would not stand up to serious inspection! I'll include a pic below for curious eyes. I am using the B&C, mounted to a horn - but it is currently resting on top of the mids! I'd like to build a box with the 12" and the Horn, all in one. I'll include a quick sketch to illustrate my rough plan. I guess I'm looking for input from anyone who has experience with this or other similar speaker/cabinet designs. What should I watch out for? Anything specifically I should look at or consider? How do I figure out the volume of the comp and horn in the box? Fane suggests a box with a volume of 30-75 liters. I'm pretty confident I can calculate the various dimensions needed to match my design, but I know there's going to be something I haven't thought about! Any and all recommendations welcome. Thanks in advance, Ben. Pics for your viewing pleasure: Rough plan: |

Is this the right place to post this topic? Would "New Projects" be more appropriate?

Just what i was thinking
But in terms of the box, if you are looking for a full range box, for domestic use, then a sealed box will have more merit than a reflex box. Sealed boxes are very forgiving in terms of volume and tuning as they are inherently simple devices, however keeping box proportions correct, introducing good bracing and plenty of internal dampening material will all improve performance. Sealed boxes roll off in a much more gentle way at the bottom end than a reflex enclosure so you may well be surprised how low you could get the box to play. Efficiency down there will be limited however and you also need to pay attention to excursion at higher powers.

Thanks for the responses so far...
LED's are purely aesthetic. I've already built a set into the current box - basically to show the signal level in a very crude/rudimentary way. Thinking I'll make a circuit for each of the top and mid sections. Really just some fun and a nod towards some of my favourite Dub systems such as JTS and Earthquake. Consider it a vanity project haha. Was fairly certain that a sealed unit would be best - especially considering my limited knowledge and experience! The ported box on the drawing is just a reflection of the existing 15" bass cab. I included it for visual reference. Hoping to design something to march the front facing dimensions, so it can sit on top nicely. Any "real world" thoughts (rather than simulations) on a suggested volume for the box, or for figuring out the space the horn would take up?

The leds flash like a vu meter to show signal going to box.. similar to Jah Tubbys and others have in their top boxes.. (i think)

Jammin - yes me boss! Did wonder if I might see you around here!
I'll get in touch with ya privately... Had occurred to me that finding materials may be an issue atm...

Jammin - I haven't tried WinISD yet. Is it fairly simple to get working with ideas like these?
Once I've wrapped up some proper plans and dimensions I'll tap you up for those off cuts! Edit - Downloading now... will see how I get on!

So, I've had a bit of play around... Inputted all of the
parameters that I can see/find/match up from the spec sheet. Saved the
driver... Gone to open the driver, but I do get a prompt that it fails all
integrity tests... Kinda ignored that for the moment out of curiosity.
Here's some of what I'm getting out of WinISD. Does any of it look right or wrong - what am I missing? Orange - 30 L Blue - 40 L Red - 60 L Green - 75 L Assuming that my data inputs are correct and the warning doesn't count for anything(??) It looks like a 40 L box would give me a tiny peak around 100hz with a nice smooth roll off. Not worried particularly about top-end performance as I have the compression driver to deal with those frequencies. Using most of the presets/defaults whilst I get my head around what I'm looking for! ** Data sheet posted separately now I've figured out an Imgur link - see next post!
