Re: 4 July Hi-FiThat is quite a "hole in the middle".One thing I notice is the steep LF rolloff on your TH-118 looks a bit more like my Keystone TH using the BC-18SW115-4 than Langston Holland's 18sound loaded TH-118.The Keystone is the blue trace, Langston's TH-115 is the purple, white is his TH-118.Are yours loaded with BC-18SW115-4?What filter settings were you using?

That is quite a "hole in the middle".

The Keystone is the blue trace, Langston's TH-115 is the purple, white is his TH-118.
Are yours loaded with BC-18SW115-4?
