sorry i have several Allison and IME there are VERY few if any tweeters and midrange available plus they are not always the same if a different model the only way i have been able to get drivers is to buy whole speakers , survivors who have some that still work! i even tried to have some made they are VERY difficult virtually impossible and trivia, were assembled by robots ! yes 50-60 years ago!
if i hear of some for the CD 9 i promise I will let you know straight away!
watch out they are even selling fakes now on e bay! i exposed several ! reported them!
i was going to get some CD-9 lay them horizontal and try to use them as a center channel speaker! YES! two of them! would have to reconfigure the T/ M to vertical!
and yes they would require new crossover design !
i am trying to get enough to have a all Allison 11.1 channel HT !
do you think comb filtering will be an issue ?
hello y’all well looks like i may have found nice pair of model 9’s to buy for my Center channel speakers !
what do you think is a fair price ? 
we hope you do not mind our post here ? thx
what to do for a ALLISON C channel ?
Allison never really made ANY dedicated, properly configured Center channel speakers .
I pointed this out . it is true.
SO here are some ideas, and rationale please contribute to the discussion !
NO i do not have the skills and experience to build these to my ideas . I know someone who could however , I doubt they will they are just kickin’ back too much these days !
Then ol’ HF tries to say several Allison speakers can WORK as a C channel .stand in
No,
not really,
we need a horizontal configured speaker w/ two W both on the ends and a T on top, a Mid below it .( ot Two mids ) the CENTER CHANNEL is the MOST important speaker of all HT speakers .
The problem is noones C channel is BIG enough!
the C channel is the MOST important for movies, HT
most of them skimp on the W size , are only two-way and do not have a big enough Midrange
Even a really good c channel like the SVS has a lame small 4" mid . ( and NO magic ALLison dispersion ) !
MAYBE 2 allisons CD9 on their sides would work w/ reconfigured T & Mids big enough ?
why not mount them ( extra woofers , mid bass ,) push pull? and lets use the 9’s 10" and some allison 8" and some allison 6" too yes mounted push pull as a 4 -5 way ? ( some think the 6" W of the AL125 have better upper bass ) system
yes we will use filter and a sub too all 90 hz? 80hz ? or ? ( you choose ) goes to sub
the C channel needs to be the BEST and Most expensive, biggest speaker of ALL
sorry many ( if not all hopefully ) you old school 2 channel aficionados just do not understand . Neither does HF He needs to think bigger , better .
He likes to mod Allisons make them franken speakers ! lets get busy ! apply that supposed genius ONE more time ! lets get a tour de force ! ( please use all Allison drivers ) 
OH! look YT video guy already kinda proves it a good idea Two Center Channel Speakers - Yes Please! ( but he did not configure , reconfigure the tweets and mids did he ? NO
