I had to.
2226 in the car of my hatchback with 120watts(350w plate amp,one input only so -3db, into 8ohm)
Makes me appreciate normal room environment,the cabin rattles were wicked!
needless to say,the poor RS meter (126db) was having the needle hammered to its stops easily ,especially on 30hz hahah!
had some fun
CD Sine.(non calibrated RS meter measurements)(=+3db at 50hz , and +5db at 30hz???)
80hz +0db
70hz +6db
60hz +6db
50hz +1db
40hz +4.5db
30hz +6db
20hz -18db !
my jbl page (from index) shows the ebs response.
