Hi. About to start building a MT122 but with only one 12" driver, basically for the weight side of things. Would love the full size but needs to be portable. Right the question i have is, The compartment that the 12" driver fits has a max depth of 148 mm and the recommended driver for the cab is a P Audio SN 12B Neo which is 152mm. Have i got that right?

Im using a JBL 2445J on a 2380 Flare with possibly a Fane 5020 Slot tweeter. 
Im using a pair of EV T18 copies sat in the middle of the stage with Fane 18XB. Running the bins with a QSC PLX3402, and also will be running the mids with another amp of the same type. 

Need suggestions for an amp to run the tops too please.

	I find P Audio a bit slack on data. But are you aware they have a uk site and an international site? The international site one is generally better. That's probably a typo above. Look here, it says the depth is 142mm, which will fit. paacoustic.com

	Only thing is, the measurments you show aren't the outside dimensions from the front to the back but from the inside of the front to the back so it might be right :(

	Oh yeah, that was tired an unobservant of me. You might have to wait for someone who's built some to help.

	Hi! You are absolutly correct! The plans is not adjusted for P.Audio SN12B and the rear chamber is to small. The orginal driver was PD123. Look at my topic about MT121 where I split the MT122 in to two boxes. One MT121 and one single M12. I have altered the plans and changed the 18 mm ply to 15 mm http://www.speakerplans.com/forum/forum_posts.asp?TID=8798 I have just checked a brand new P.Audio SN12B and it is 150 mm to the top of the gasket. P.Audio says 152 mm in one site and 142,5 mm in an other... Confusing! Edited by pope - 02 April 2007 at 4:44pm
