Loved the result when I built the Fane Sovereign 12-250TC plans posted by Scottmoose here:
https://www.diyaudio.com/forums/full-range/246746-12-range-fane-12-250tc-39.html
A friend sold me his pair of 12-250TCs for cheap and I couldn't resists. Now I have a quad of 12-250TC drivers.
Does anyone have any ideas how to create a twin driver box for two Fane 12-250TCs? Or an OB plan with two drivers per side?

The 2x2x15 might work, it is a nice build.
norman bates would you recommend the "2 x fane 12" (stacked over under).
Box will be 50" tall, 24" wide, and 15" deep.
Basically it's a box 15" x 24" x 39", but raised up 11" so between 2 drivers at ear seated level.
Top driver 1" from top and 1" between drivers."?
Have currently laid the cabinets I built on their side, with with 2nd Fane driver mounted on an 18"x18" open baffle. Looks odd and take up a lot of space, but I think it has some potential...

12" driver on a 18" wide open baffle ?
dip at 1khz, peak at 500hz, then rolling off below that (probably)...……………….
I couldn't tell you what will work.
I aimed the driver not quite at where you sit, then eq'ed down the 1-4khz range (that is still there 90 degrees off axis), sitting off axis will not knock that area down.
That way, you covered a larger area with "balanced" (to me) sound.
Otherwise, if 1 driver is directly aimed at 1 listening spot (and eq'd), you probably get 1 set of ears listening area 8' away, stand up and you will be upset at the sound quality (not driver's fault).
Might be you have to build and play and tell us.

Np.
I’ve made all sorts of stuff just so I can weigh in “yea I tried that and this is what I think”, etc.
Great driver that moves some air (bass) at a great price (after a squeak of eq).
Amiright?
Who knows, just my opinion.

maybe along these lines

12-250TC was very clear in a Karlson K12, but had very little bass with
35 liters back chamber. A dual Karlsonator or XKi would work to get some low end.

From what I have read so far, K12 gets the midrange right and that's important to me. I have been reading up on Karlson K12 and its "Dutch" variant - it's a steep learning curve (but I can manage the woodworking part). freddi's posts here at diyaudio are terrific. Quite a few uploads for me to see on Youtube too, when I have time.
Just for fun, been listening to this configuration in the attached pic, with original speaker on its back and a 2x4 baffle clamped with second 12-250TC driver. Hopelessly unscientific, but lots of fun to try and experiment...

did this experiment ever go any further ? I have lots of ideas I'd like to try with the 15inch version mainly involving trying to improve the dispersion
There are certain limits in regards to what can be achieved with the off axis performance of these drivers.
Yes, there's a limited few tricks one can utilize to be reasonably happy, but there's no such thing as a majick potion to drench these drivers in.
In some settings it is a blessing (very nice in small rooms or rooms with a lot of reflective surfaces), in other settings it is a curse (not enough for wide area sweetspot or outdoors use IMO).
Value for money - Most certainly!
Absolute highest end sonic fidelity - Not really, allthough they can be quite good in the right circumstances.

what tricks did you use personally ? I find the sound quality excellent with eq applied . it's relaxed and unforced I'm assuming because of the large surface area reducing excursion amd therefor distortion ? . the only fly in the ointment is dispersion . if it was slightly better that would be fine obvs wasn't expecting miracles but a bit better would be good !
They are quiet ok untill about 40° off axis actually, which is exceptional good for such a big driver. Smaller drivers are better at this off course. But i like my build with these, in a room that is largely with relative thin drywall walls with a lot of isolation behind it (so not very reflective).
could we see you're build I'm interested in what people have done with these I think they have a lot of potential
I posted it before but here it is. It's a 175L reflex tuned to 35Hz (but reasonable flat to 30Hz), build in a oldskool manner (inspired by the Altec Lansing 620 but with a fullranger in stead of a dual concentric).
Wood is 18mm birch ply, frame is from 27mm pine, the inside is lined with 10mm thick felt and the driver is mounted sandwiched between 2 plates. This setup is ment to be used with 20w or less (otherwise the bass response go up due to limited xmax) but at 98dB sensivity (measured myself) that is not an issue. I do use a filter to tame the highs a bit. The amp i use to drive it are the Pass ACA kits sold here on this site, but set to mono balanced (so 15w).

interesting thanks I've been experimenting with placing differently spaced pieces of wood in front of the driver to try and influence the dispersion . placing vertical pieces of wood in front reducing the amount of the driver you can see to around the middle 7inches improved the horizontal dispersion quite a lot actually in a similar way to spendor have done in the past . you could walk around the room and it sounded much more uniform .
Tried the "modpodge" route of diluted PVA glue on one of them just for the sake of trying, there are some changes but I am unable to conclude whether it's for the better or worse. So "modpodge" on the center cap and wizzer = definite changes but overall it's still more or less insignificant after looking at the end results.
Did some experiments using various shapes of melamine foam on the speaker grill, and while it does help on some resonant behaviour in other aspects it dampens a bit too much so...
After some back and forth I ended up just using a metal grill in front of the drivers, and a bit of EQ, nothing else.
Might go back to adding some melamine foam at a later point in time.
I agree, quite good, and exceptional indeed for a FR this size. I just want people to have realistic expectations, no sense hyping this up.
Fantastic value for money, and this is a very nice driver that can play full-range from 30Hz to over 10kHz and it can do that quite loud - ALL BY ITSELF! AFAIK there is very little competition as not that many drivers can do what this driver is able to accomplish. But there is no such thing as magic and people should have the right frame of mind to be able to accept the compromises made in the development of this driver.
In my opinion, it is the absolute best value for money loudspeaker driver I've seen to date.
That is not the same as it being able to make "the best loudspeaker in the world", just saying that it's exceptional value for money.
Nice setup btw!
