Well, I suppose that no matter how complicated we choose to make it (or not), the REAL Challenge isn't all the fun, and added electronics, but rather the need to carefully position Subs/Mains, and Seating to have any hope of a good result. Our Rooms in general were NOT designed to be Listened to.
If your Speakers are falling apart with anything more aggressive than a Tambourine...none of above applies. See your Retailer.
Try as we might, Small Room Acoustics can be a struggle, and while "Experts" all claim to have Sensational Rooms with the Acoustics of a Classic Concert Hall, a majority do not. I've been to more than One "experts" house only to be mortified by the Muzzy, Disorganized Crap I heard, and also to Homes where the very un-spectacular gear sounded Amazing!
Combining Quality HiFi, and a Living Space IS often a challenge, and that's a Statement of Fact. Wives, Decor, and simple Practicality are always major factors. XOs, etc will address none of the above. Because I absolutely LOVE Loudspeakers, I endure the challenges. It's very Rewarding to hear a life-like Vocal, or a plausible Kick Drum in the middle of the room.
We are still Free to do as we choose, and I choose not to fix problems I don't have. So much easier.
Best,
Curt
Late Edit:
Kai...surely you've experienced the "Trade Show Darling" Speakers that Wowed the Masses with their ability to reproduce "Flute & Triangle Duets", or float a Ghostly, Miniature Vocalist in space...but nothing else. To this end is why I'm so insistent on a capable Main Speaker that is merely augmented (not placed on Life Support) by the Sub(s)
