Help build Lowther: Big fun Horn

[tuanna812]

Hello,

I am fan of lowther, i prepair to build plan for driver lowther, i loved plan: Big Fun Horn but it less information about it. I think by this desgin i cant successful to build Big horn - How can you help me detail of Plan (Cabinet) of Big Fun Horn and CNC of it

The Big Fun Horn is Ketil Parow's baby. A big rear loaded horn meant to be used in the corner, it is capable of bass response to the low 30's. Truly a full range system. The All Fun horn is similar, but smaller and slightly less bass response.

hello Tuanna
Which Lowther do you own?

Scott (moose), what do you think about this horn? Fc 32 hz?
How would they compare to the kirishima? (I know they weren't designed for Lowthers)
What about a new bigger design for the Lowthers? like someone from australia suggested in the Kirishima thread? I was thinking on this idea for a while... we (Lowther owners) can join and donate some money for this design. What do you think about it? 🙂
I own a DX3 in MJK MLTL, but was never completly satisfied with the bass

Thanks for gaston.

I had some lowther driver: pm6, pm2 , pm4 ... I read and know about Big Fun Horn can be down to 32Hz , and it can use many driver Lowther by lowther Club noway.

This design is completly and successful for bass. I think join group is great.

If you had new driver lowther dx3 - it had solution about plan using All Fun Horn , smaller than big fun horn

The "ALL Fun" Horn

The article outlines and details the design and construction of a back-loaded single driver horn using a new driver from Lowther, the DX3. The article's approach is of a practical nature, with emphasis on all practical steps of the design process, enabling readers to fully understand the underlying principles of this particular speaker, as well as completing a horn loudspeaker design of their own. The article has previously been published in SpeakerBuilder (now AudioXpress) magazine.

The plan as drawn seems perfectly adequate for a construtor to make this speaker with. I don't know what you mean by making a better plan? You mean a cut-sheet? That is quite a bit of work as each piece (and there are many) need to be drawn (or modeled) in CAD and them the program can auto optimize the placement for a cut sheet or a good designer can layout the cut sheet manually. Either way, you are talking about a full 3d design from a 2d plan.

There are some other drawings with a little more detail available here: Lowther-America

According to the website, Lowther-America also sells full-sized detailed plans.

Thanks all, how this Big fun horn is suitable for lowther driver ? Pm6, Pm2, Dx3, Dx4 ,...

Thanks

It is a clever design, if you can handle speakers that are 85 cm deep.

I've just seen your thread and since I own a pair of plywood BFHs, I thought I might post a reply. The Big Fun Horn has a large but rather shallow compression chamber. The Lowther PM2A, 5A and 4A are too deep to fit in the BFH. the PM6A gives a very poorly controlled bass. I'd strongly recommend the PM7A. This gives a lovely balanced, very listenable, presentation and works well with a variety of solid state and valve amplifiers. The Lowther DX3 also works well giving a more 'modern' detailed sound.
