Lol, I see what you mean.

Not sure why but the pictures posted seem to have been elongated. They are not that long in reality.

@lcd950 I see only a subwoofer, where are the main speakers ?

@squiffything You can't call a tweeter something with a diameter larger that 2-3" and having a moving mass > 2-3 g

Noted, I mustn't call it a tweeter..... I can call it a tweeter, but I'd be wrong. If it's not a tweeter then it might be a mid/hi speaker and the tweeter will need to be added. I have to find me a little pot to stick a tweeter in.

Main speakers, pair of isobaric loaded transmission line.

Nice, but what is the advantage to use isobaric in TL?

And, is there some kind of horn sub in the equipment rack?

 

[Nico Ras]

Lower compliance and increase mass. Useful output down to 17Hz or so.

Great look Nick, very clean install.

Would also love to know more about the iso-to, do you have a rough drawing?

Part 1 My interpretation of Yuichi 480 horn and bass cabinet.

My interpretation of Yuichi 480 horn and bass cabinet.

This is my first attempt at anything horny.

I used copper for the horn cut from 4" type b copper (nice and thick), annealed copper and beaten into shape. Used lead for the fins, made a mould and smelted.
Colourised the throat with any oxy torch to get different colours, (not very good at it,) then used pouring epoxy to keep the colour and make it shinny. The out side was left as is.

My interpretation of Yuichi 480 horn and bass cabinet.

Second stage was the cab, had a rough idea of the shape and went along with it
Was using Eminence Kappalite 3012lf http://www.parts-exp...97zb000bib0005c
In a mid sized vented cabinet of about 50ltrs.

Used 16mm MDF and cladded it with a mixture of 7mm x 70mm Merbau slats and pine.

Kerfed the rounded bits (what a bugger to do)
All joints were rebated for strengthening.
Top and bottom compartments were braced.
Bracing behind the driver.
Filled the bottom compartment with dry river sand.
Painted internals with tar paint.

Great build. Congratulations.

As always, I recommend varnishing the woofer drivers with Dammar varnish.

Cheers,

Paul your woodwork is stunning! I have a question about your horns that I hope doesn't offend you. They appear to be made from metal, doesn't that make them ring?
