Interesting. I didn't realize that the crossovers were changed, nor that the integration was improved in the EM-ESL.
Reading up on the woofer-blowing problem kind of terrifies me. I don't need to blast music so it might not be something I have to worry about, but it's still concerning, to say the least. I don't want to have to handle a new setup with kid gloves.
And as far as I know, Martin Logan ditched China. I think the EM-ESLs are built in Canada, which... while Canadian, is still a respectable place. I haven't heard of build quality issues.
