1. sell 'm
2. build a 12/12/6
First I would have a need for a compact, full range bass cabinet designed to cleanly produce wide band sound at a target spl in a performing venue setting. Then I would design the cab and model crossovers around candidate drivers (woofers, mids and tweeters). Then I would order the parts, confirm the TS specs, adjust cab tuning as needed, and build. Then i would test and tweak as needed.
The 3012lF is not the best 12 inch bass guitar driver or even the best 12 inch 'sub' driver. It's only the best if it meets a particular set of needs (performance targets). If you are thinking of building a bass cab, what are your performance targets? Once you have these, realize that the woofer choice and cab design are not nearly as challenging as the crossover design. It is probably safer, and certainly easier to pick a design of known quality, that meets your performance targets. The suggestion of the 12/12/6 is a good one… if it meets your needs.
(If I were you) I'd build a fEARful 212 and put a little horn in it like I did.
It's my favourite cab.
Light weight Neodymium rare earth in ear monitors.?
I'd try them in my cab
see post 10
or build another after talking with Duke
Cool. Thanks for the input guys!
damn it, i'll bite:
Where did that photo come from and how can I purchase one?
I'd experiment. Buy some plywood and make a cab similar to what Xsonics and Glasstone are doing.
Not worth it. One of those drivers needs more air space than either of those designs provide. Two in there would be a waste.
It's been awhile since I've been on TB now I remember why. The OP asked for suggestions. I gave my opinion and you step all on it. He was asking me and I answered. Give your own opinion and leave mine alone. I don't know why you just didn't state what you would do and leave it at that. But I do now know what a troll is.
Some people would rather see the OP get good results, and not waste his hard earned cash.
My opinion is that he should get good results. If you dont share that opinion you are not helping him, you are hurting him. Dont act so indignant.
A Bill Fitzmaurice Simplexx 212 would be a good, simple, well thought out way of using the two together.
Put them in a dual 18" scoop PA cab. The sound will be huge.
NOTE: The OP wanted opinions, so that's mine. Don't jump all over it just because it's stupid.
Fact, those are subwoofer drivers with poor bass mids.
Opinion, a very few people like the sound of subs run full range.
If you need subs, build subs. BFM's subs are louder than fearful thanks to horn design, but big cabs!
Otherwise, 3-way cabs or sell them.
the 12+12+6 would be awesome. for more flexibility I would probably build a 12/6 and 12sub. pass on the tweeters, I get plenty of highs from the 18sound 6".
I use a couple of 3012LF drivers. One is paired with a 18sound 6 inch mid driver and the other is in a box by itself. I built the 12/6 myself and bought the 12sub from a fellow DIYer... goes by Cableguy here on TB.
The design is by this guy who calls himself 'greenboy' and the name of the design is 'fEARful'.
They are hands down the best cabs I've ever owned or played thru.
Everything I've read on the BFM site indicates that the Simplex 12 designs are better-suited to full-range drivers like the Deltalite and Beta 12s. Those drivers will cross to a tweeter better than a dedicated woofer like the 3012LF.
The 3012LF can be combined with a good horn-loaded compression driver in a high quality two-way system. I've used it in two-way systems for high-end home audio, studio monitoring, and light PA duty. The crossover work required to get the 3012LF to sound good in such applications isn't trivial, but neither is it unreasonably demanding. It does have an anomaly that is easy to overlook in the measured response, but also easy to address once the designer is aware of it. I have people using my two-way 3012LF bass cabs to amplify a wide variety of instruments, not just bass guitar.
So imo and ime, the 3012LF is a quite viable woofer that happens to have subwoofer-class excursion.
