this my current project ,this my next speaker,They are in my bedroom being tested.
In the world of horn speakers bigger is better I wanted to build a pair 8 feet tall but was reminded that I can,t really walk never mind carry these monsters into our tiny house!
When I play a piano CD it sounds like a real piano, really real!
These are Lowther’s English speakers there is a magnet on these babies half the size of a bowling ball and the cabinet design is Kietel Patlow’s “All Fun Horn”.
I got the plans from Jon Van Halen of Lowther America.
They slightly smaller than the last ones dimensions are 1100mm tall by 500 deep and 300mm wide at the front the back bottom corner is cut off for the horn mouth opening. I built the cabinet from 18mm ply and will cover this with 8mm solid ash then stain and finish .This project shows the inner workings of the back loaded horn design.
I just got the wood last week and hope to start preparing the 1” ash .I plan to get it planed to about 24mm x300mm x 1100mm boards and then rip it on my Felder, the rip blade kerf is 4mm so I should be left with 2×10mm thick boards with 2mm for cleanup i will cover the speaker in 8mm boards.
I thought about ripping veneer on my band saw but it won,t cut more than 130mm and thats at a pretty slow feed with a Starett 4tpi blade.I don,t have the spare cash to get a better ripping blade for the bandsaw yet, I spent it all on the wood.
I have to decide how to make them stand upright as the back corner is chopped.Some people just keep the back going down I may try something different or not!
I may be a while as I am pretty slow these days. I don,t mind as I may less mistakes I couldn’t rush if I wanted to but I will post a part 2 now with more pictures and part 3 when it’s done
Thefirst pictures shows the inside and shows how the sound travels as the horn gets bigger
and it gets louder.
The other 2 on shows one speaker on the slider.
