The story here started on another thread last week, and I should've started a new thread then. Received the Atlas 15 Tuesday. Came home and connected it up as per instructions, calibrated it, and fired it up! Well, with the 4 ohm amp powering the 4 ohm Atlas, oh man, what a sweet sound. I used DVE, but had some trouble with levels (saw the relevant thread after, of course) so used Avia and VE, but what worked best were the tones from my reciever. I also made a test tone disc using NCH (thank you). My windows resonate at around 41.5 Hz, and the dog freaks out around 35 and below. Room gain helped a whole bunch, because I was able to get 20 Hz at around 82 dB. 3.7 ft^3 enclosure with a Q= .707. MDF is so cheap, I'm thinking about building another enclosure to get a lower Q just to see how tight it can really get. (oh no, the DIY bug has struck again). Anyway, the Atlas is everything and more I could have ever hoped for. I haven't been able to really listen yet, but this weekend... Only a few MDF mishaps and veneer probs, but nothing serious. Haven't been able to get the amp to self power on yet, but maybe the signal needs to be boosted a bit. If anyone knows how to post pictures, please let me know. I really want to share this first DIY with all of you.
