Yup Josh, Linkwitz uses a "W" style open baffle frame, which is what I used before the guy in Canada started making his H frame. They're both good, each having advantages and disadvantages over each other. The H has better structural bracing, the W having a large expanse of unsupported panel on each side, leading to resonance. But the W does purportedly provide some reduction in harmonic distortion due to the opposing force relationship between the two drivers, created by them being mounted on baffles 90 degrees to each other.But both posses dipole characteristics, with nulls to either side, loading the room in one less direction (side wall to side wall), resulting in less room boom. Being dipoles, their SPL drop-off rate with increasing distance also matches the dipole speakers they are mated with, keeping the balance between the two the same regardless of listening distance.
