Thanks guys ! It took me more than I anticipated to build them since my cabinet making skills are pretty limited . I did not rush, took my time & followed step by step instructions .Very pleased the way they came out.

First of all many thanks to you & everyone else who was involved designing these horns. I actually added 1" wooden isolation cone ( pics ) underneath the horns ( about 5dg tilt angle ).To support back of the speakers I used kitchen cabinets shelf brackets (pics ).

Looks really nice - great wood working skills there. I never understood why speakers sometimes have sharp spikes on the feet that will concentrate all the weight to a singularity that will either cause damage to the floor or whatever they sit on...

Because some people have carpets, and spikes were originally intended to pierce these to improve stability (viz. to stop the speakers falling over whenever anybody walked past). The original purpose has become a trifle diluted over the years.

My apologies for digging up an old thread. I'm looking for a HornResp model of this design. Is one available?

Not that i know of.The design was done with MJK (a step up from HornResp IMO) and a number of proprietory tools.

I might put together a model this weekend if I have the time. It looks fairly straightforward - rear-loaded horn with a damped back chamber, horn in four segments... Are there any impedance measurements of a built horn available that I can use to compare against the HornResp model?

any problems using mdf for this build? I know mdf is considered less resonant than coated plywood but I have a bunch of 3/4 mdf and was considering using this for all of the build except the front baffle as shown in a previous post

thanks

Huh?

You can build out of MDF, but the enclosure will be more coloured than if you did them out of good ply. 18mm MDF is about the same stiffness as good 12mm ply, but has much higher energy storage,

thanks for the help

This is one of those topics that can quickly devolve into religious / polemics territory - suffice to say that the physical characteristics of the two materials (MDF / high density plywood) are quite different, and those differences do affect the sonics.

Anecdotally, based on a few comparative builds from over 10yrs ago, I find the plywood enclosures to sound much "faster" and "musically consonant" - those are not scientific terms
