Yah it is a pretty cool story, and as I mentioned it sounds like **** but it loud, and I have since upgraded it to a 12w3 for more reliability(not as lound in current box). I didn't get into this to start a pissing match, but you actually brought the W7 into this based on your quote above. I mentioned that I though the W6 was a better solution instead of the W7 as it will play louder with les SQ. If you are selling the W7 as a HIGH SPL woofer you are not selling the right equipment to your customer, the W6 would be a better solution. As I mentioned in pervious post, I would love to see real world test results of any subwoofer vs. any other subwoofer before I would recommend it to another customer without previously installing one myself. I had said almost the same thing in all my post and yet I hear the same thing back that it is just better. Many post have in this section have mentioned different ways to get a great SPL number. Don't even try and challenge how long I have been doing this, I don't know you and you don't know me. Just becuase I have a different set of standards than you doesn't make me or anyone else inferior to you. I have taken this career seriously and I have a huge customer basis that loves my work. Last thing, even though the Solo X is not my cup of tea it is a BMF of a woofer and that changes the variables of the original post. This will be my last post in this section. P.S. Secretariat just called me and asked for you to stop beating her.
