This whole discussion has all been about open baffle merits, referencing the Linkwitz designs. What’s been totally missing from the discussion is the merits of active amplification. All of the Linkwitz designs use active amplification. Very few, if any of the various muy expensivo hi-end designs use active crossovers. In many ways, active crossovers are as significant to the Linkwitz designs as is open baffle.
Linkwitz was a stalwart proponent of active speaker designs long before DSP crossovers and equalizers were even available. He also designed his speakers for excellent on and off axis response, an art lost in many high end makers today.
I wanted to talk in this thread about the general limitations and benefits of open baffle designs and how they compare to boxes or even other line sources.
The LX521 is a standout in my mind because it is a 4 way, allowing for fine tuning of the horizontal polar response, but having to use 4 channels per speaker is a big no for me. 😁
What do you think the active part of Linkwitz designs brings others lack?
