As those of you who have followed my posts will know I have been using circular interchangeable baffles to mount and evaluate a number of 8 inch midrange drivers in an existing main baffle.
I am now settled on the mid ranger and my attention moves to the
dipole tweeter.
Unfortunately the additional circular baffle has the negative effect of pushing the tweeter further back into a recess, giving opportunity for reflections as the forward sound emerges. Its not unlike a crude horn loading. So I would like to debate the options.
There seems, to me, to be 3 main options
1. Apply foam around the tweeter opening to reduce reflections
2. Mount the tweeter further forward so it fits flush with the baffle
3. Mount the tweeter (without significant baffle) alongside or above the main baffle so it is essentially in free air.
The tweeter will run from about 3Khz upwards
What are your thoughts?
