I have purchased 3 T34Bs for left, center, right speakers (music primary) and need to move towards the next purchase.
I have been perseverating for months now. Almost purchased 3 x Bliesma M142A's, but I wondered if a 3-way might be biting off more than I can chew. Also, it seems that it would best match the T34 without a waveguide(?). This lead to lots of consideration of WG or not, power response, etc., more paralysis by analysis.
Room is well-treated acoustically.
I am picturing a wide baffle with large roundovers (a lot like the Grimm speakers). Would try and model with passive crossover, but unless very successful would move towards DSP.
Simulating an ~ 21" baffle in Vituixcad suggests full baffle support down to ~ 250 Hz. So at an approximate 1.3Khz XO in a two way, both drivers will be radiating into 2pi space, so measurements of dispersion in an IB (hificompass) should largely match what I will see(?).
@mabat 's waveguide, as an example, looks to be 120 degrees in dispersion, so would need a midwoofer to hand off to that smoothly.
Any thoughts? Thank you,
Bill

that is the same driver in both graps.
if a 2 way and that's your options, the 8" is the easier choice, will cross higher where the T34 is more comfortable.
Half the mms, 1/3 the inductance, higher sensitivity etc. makes it more of a midwoofer.
Look at seas w22ny003. Excellent linearity and off axis, no breakups, distortion at purifi levels, no cone edge resonance, very easy to work with, sounds great, smooth, clear and transparent. Add t34b in 6-7inch wg, use lr2 at ~2000Hz, fine tune the levels in 2000-6000Hz and you will have excellent naturally sounding speaker with tons of the details without spitting the details to your face or sounding too forward and analytical.
Thank you, Arez, you are of course correct.
And thank you PKAudio for the suggestion; I hadn't considered that one.

Wow, that looks excellent. Thank you.
Would you happen to know the box/baffle size with which those measurements were taken?
I am having a hard time wrapping my head around the dispersion of a driver based on size/geometry (before it breaks up) in a large baffle v the dispersion changes seen on smaller baffles.
