Apologies if this has already been posted about; others have commented on here and other forums that removal of the multi-hole faceplate on these capsules results in a much smoother HF response.
Rather than lathing them off (which I lack the tools to do), or sending them to a machinist (which I don't think the capsules are quite good enough to warrent that expense), I found that simply carefully cutting them away with a razor saw works just fine.
Three cuts just outside three pairs of holes, then three tiny cuts between each of these, just inside the outer edge. This leaves the maximum amount of material to maintain structural integrity, while still removing most of the obstructing material.
Haven't noticed any negative effects.
The photo shows the TSB-160AO; the omni version, mounted in 1/2" copper pipe coupling + cap (needs a very effective shock mount). The omnis don't appear to be available retail from any vendor, but come with the Monoprice SC100s.
Indeed, the safest way to grip these 160s in a vise for the cutting, is to first wedge them into a copper pipe coupling. The couplings aren't made to terribly rigorous standards, so a little material may need to be sanded from inside the coupling for the capsule snug down inside. The 165 is too big to fit.
