phase plugs

Woah! - a 4.5 year old thread exhumed from the grave .....  

But to answer the question, yes.  A plug would decrease the throat area, and increase the flare rate of the initial section of the horn, both of which could be beneficial to top end response, although it may have some impact on the low end.

An experiment:
Place an MT122 on its back on bricks so that it can still be plugged in.
Disconnect the horn
Play some full range music through it at a comfortable level to listen to right in front of it.
Holding a full (for mass) Coke bottle by the neck end, carefully lower it into the throat WITHOUT letting it drop onto the cone, and listen to the difference it makes at different distances from the cone.
Try it with different size Coke bottles (did I say not to drop it on the cone?) and compare.

Hi, im a joiner from devon.. i'm really interseted in building a phase plug in a mt 122, yours look as true as it gets... can you help me?

wood ch'ka a plug for the mt122 cant be done, you would need to completely re design the horn first....... at which point it would not be an mt122 but a 2x12 midtop horn......
