Thanks for all the knid words everyone.
What you see here represents a LOT of hours of work. With quite a bit yet to do. I just couldn't stand walking through my garage day after day looking at them and not listening to them. The only time I have to work on them is the weekends. I suspect that I could have finished in a week or so if that's all I had to work on.
I'm going to listen to the for a couple of weeks, maybe a month before I make the conversion to ported. The good news is that by virtue of the design it'll take me about 30 minutes to convert them from regular La Scalas to ported La Scalas. Then I get to play with port lengths. Again easy to do. I can swap out port shelfs in under 15 minutes.
For the last 3 months or so I've been listening to my "poor mans" Cornscalas. I got a pair of the PH-800 horns and the appropriate crossover bits from Mr. Crites. They're nice no doubt. They do have more bass extension. What they don't have is the accuracy of the La Scalas. At one point yesterday I had one La Scala and one Cornscala hooked up. By setting the old Marantz to mono and sliding the balance control I was able to give them a good A/B comparison. The La Scala won. Hands down.
I don't suppose there's a marked for Cornscala cabinets without drivers?
What's next? HMMM... I'm thinking tubes...
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, Champagne in one hand - strawberries with whipped cream in the other hand, body thoroughly used up, totally worn out and screaming YEE-HAW What a Ride!"
