As some going to the Gauteng DIY showcase might know I'm building a pair of Frugal Horn Mark 3's. here are a few pics of my progress so far...

First I ran the EL70 drivers in for a few days after I received them modded from Planet10HiFi.

I had the cabs cut and glued by a friend with the necessary tools, I received them with one side panel off so that I could glue the felt and add the stuffing.

I also stuck valcro strips on the panels to hold the acousta stuff in place.

Drilled the holes and fitted the drivers

Rolled some press stick to help seal and hold the loose panels so that I could get them playing and listen to hear the effect of the stuffing. This would also allow me to add or remove the stuffing easily.

My first listening impressions:
At first I was very impressed and had a smile on my face. Female vocals sounded very good, Diana Krall had new life in her CD's that I know very well. After some more listening to other source material such as Jack Johnson's Sleep through the Static I found that there was a brightness that was quite harsh and listening fatigue set in. Other genres like Jazz at the Pawnshop sounded good with the sax sounding very accurate and all instruments were easily distinguishable and well separated but overall I thought the FH3's were lacking warmth and body. The upper midrange is too dominant...I think.

So, I would like to know where to go from here with the stuffing arrangement. I have 30g in the V and 20g in the mouth below the driver. I have another 20g to add to the mouth as the design mentions 20 to 40g depending on the driver.
Any suggestions on improvements will be appreciated.

ALF and Alternativeroute know this speaker....your inputs will be much appreciated and also Ian (JimGore) of course!!!
