I think it's 26 with the options and less than that standard, not 100% sure on that though.

xmax isn't that big of a factor in SPL.

Thanks Kenny

I had read that a long time ago, I was just confirming. Also I just wanted to know the xmax for reference not to judge SPL.

 

[B_Campbell 10+ year member]

xmax isn't that big of a factor in SPL.

what if you planning on burping it at 30hz?

Hmmm.. Handled a true 10,000w during the test session; so I would say yes //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
