Well - you could, but the low freq.responce is not as smooth. some 2 dB
difference on simulation. I would sell the eminence drivers and buy JBL instead.

hi!

How about using the JBL GT5-12 in replacement for the recommended JBL 1214?

Thanks!

Sorry, the response looks resonant. Lower Bl and higher Re combined with a very low VAS.

Half the SPL and you loose the benefits of push pull driver arrangement.

Would a creative sound trio12 work in this TH?

It sims very well in Akabak, near identical response as the intended JBL drivers. If it fits physically in the design it will be fine. 24dB Butterworth HP filter @ 18Hz, LP filter looks to be good around 70Hz

I just checked you'll need to make a spacer, the driver is 1.35cm (.53") to deep and considering the CSS Trio12 has a vented back plate I'd go with at least a 1" spacer for the driver closest to the mouth

Thank you Tundra, sorry I was`t specific, but would I still need a spacer for the single driver 12 version?

I haven't written an Akabak script for the 112 or 210 versions but I'll start on them. It should be fine and will fit with the driver facing into the beginning (small side) of the horn with about 4.5cm to spare between the motor and the outer wall
