If you have solid corners the Seven Pi w/JBL drivers would be worth your consideration, even if you had them built for you. I'm close to completing the mid-horns on mine, and have been running the bass modules and 2426 horns configured as two ways for the last week. Even in this configuration they are more fun/engaging to listen to than my VSA VR-4 GEN III SEs. The latter have served me well, however the Pi Sevens have a larger stage, and are much more dynamic and effortless on complex music. They also sound good at moderate output levels, and don't need to be cranked to open up. Depending on the cabinet materials you use and whether you upgrade the crossovers with better parts, the DIY cost is around 3k for the all JBL version. Less if you can find the drivers used.
