OK, we know that simple on axis, straight into the speaker frequency measurements aren’t the whole story – getting a range of measurements at different angles gives a better idea for speakers getting general use, not the whole glued to the magic sweetspot that a lot of hifi has.
So it was time to do some directivity measurements. I don’t have the a licensed copy of ARTA so I can’t do the heatmaps ala Gainphile’s site – but at least Room EQ Wizard is a nice free package that makes it fairly easy to overlay lots of frequency response graphs in different colours.
It was very interesting when I read that Paul Spencer of the very informative site Red Spade Audio Blog was revitalising Aussie kit speaker company LSK Loud Speaker Kit
Even more interesting, for those of us put off by US import prices for the bang for buck Dayton Audio products is that LSK is now a distributor for Dayton products in Australia. Great Stuff.
I wanted to try some different waveguide options besides the FaitalPro LTH142 before I start making enclosures – and noticed the Pyle PH916 was a quite decent looking, inexpensive, candidate – but very little information about people using it at all on the web, unlike lots of other waveguides. But it is sold as a constant directivity waveguide, and in fact the waveguide I use in my Econowave speakers is a smaller model from Pyle so I gave it a try.
