Easy to understand Roy.
Couple of things. That KPT-684 is an impressive product. Looks to me like that is good out to 600Hz. The impedance doesn't change much way out there. Very versatile. Not much EQ needed there.
The K69 on the 510 is "falling" some at 4000Hz. I need to think about that w/o EQ. With EQ...Do you basically do one of those 6dB shelfs at about 4000Hz.
The KPT-884 is a real house rumbler. Nice and flat to 125 Hz. Not much EQ needed there.
Roy. Very nice work....I know that isn't much coming from a non-pro but the info really does help me.
Worked with an Architect today about a new house. A slow process. The above may be used in a downstairs "dude room". Not really an HT room....but a stereo room for me. The HT room will be different.........more theater looking with some small scale reference products.
I'll need to look at this some more.
