Frequency response isnt the problem, the thing i am not sure about is how much it will reduce the output, we are looking for a reduction of around 30%-50%. Im not SURE that the oem-2 adjustment is in that range. Im concerned that it may reduce the output too much....so your radio will be too quiet.

The soem4 has a switch that allows you to select a "range" so it will work in almost any situation while the oem-2 does not.

Its probably okay, its just that I dont KNOW that the oem-2 has the right range while I KNOW that the the soem4 does. Worst case scenario you are out $20 and you try again.
