unsound,
I will try to get some images uploaded.
The room is a testing environment so I refrain from saying what's in there as it will be different by lunch.
My choice for using the 7.2 is thou it does not have the new driver technologies of the 3.7 they do go lower. The CS5i thou they have plenty on the bottom end they have a very complex xover so to simplify things the 7.2 fall in the sweet spot.
Not better just more convenient.
Hearing the SCS4 here with the various upgrades Toms proposes was an ear opener for sure. Trying to comprehend the 7.2 with these improvements is hard to wrap my head around.
There is a sizable list of upgrades to select from hence the time to sort it all out as its one thing to make a one off to test. It's a completely different thing to have a production run with all the necessary equipment, material, and man power that is competent for such an undertaking.
Take for instance the capacitors. They are tested and configured to what sonically is superior. Then you need to source them to have the wound to your specs and wait who knows how long as you're at the back of the line with such a limited bets testing run. However, this is necessary too take Thiel speakers to a higher sonic level with a greater listener enjoyment.
I'm focusing on crossover as that presents some challenges. Upgrading caps with limited real estate space will quickly become a concern.
