Parkhurst,
Thank you for your question.
The Carver ALS has been an adventure. Between ordering, shipping problems, lack of sub etc. Then there is the speaker placement requirements. I wasn't prepared to be moving the speakers so much. (I have a rotator cuff injury).
My previous DIY speakers and external crossover are really very good and I am still using them with my home theater equipment and I would not hesitate to put them in as full time if needed. They far exceed anything I listened to prior to the Carvers.
Yes, it all seems to be worth it, the sound quality today is very pleasing.
The couple things that I'm not sure of is where to place the Synergistic HFT's that I used with the other speakers and if side wall room treatment is still needed.
