Lii Audio has recently released a new full range driver ..... the F-12.

It is somewhat of a scaled down version of the F-15 driver with a few changes.

In addition to being smaller, it has an acrylic compound phase plug instead of wood ..... although it is my understanding that the phase plug of the F-15 might change to acrylic in the future.

The sensitivity / efficiency is rated at 94 DB which means that they will work extremely well with a Decware SE84UFO amplifier.

I have been living with a pair of prototype F-12 drivers for the past few weeks and like them a lot.

Here is a photo of the prototypes in my listening room .....



Larger photo here.

The tonal balance of the Lii 12 baffles leans more toward the upper midrange and high frequencies than the Lii 15 baffles, which have a stronger lower midrange and upper bass.

Both are very good ..... and which one is "best" will depend on the listening room, amplifier used and personal taste.

In the photo above, the Lii 12s are paired with twin Lii Audio prototype 12" bass drivers powered by a pair of small plate amplfiiers.
The sound is excellent ..... a true full range system .....

I have also paired them with a small powered subwoofer and the results were good, as well.

Here are a couple of photos of the F-12 drivers -





The Lii 12s make a good replacement for the recently discontinued "Betsy & Buck" baffles with the benefit of using a single driver and slightly higher efficiency.

The Lii 12s have been added to the Price List on my website.

They also have their own web page which will be updated in the near future.

As always, I am happy to respond to emails with questions about the Lii 12 baffles.

Happy listening,
Randy

Hi Ben,

The Betsy & Buck baffles are some of the best sounding speakers that I have ever offered. If the decision hadn't been made to discontinue plywood baffles, I would still be making them .....

Best wishes and happy listening,
Randy

Hi Steve,

The F-12 driver does not fit in the opening of the template I use for the Eminence Alpha 12 driver.
I had to use a chamfer bit in my router to enlarge the opening to make it sit flat on the baffle.

I have the Steve Wilson's remastered Aqualung CD, but didn't know that there were other albums available from him.
Thanks for the heads up .....

Best wishes,
Randy

I would like to thank you Randy for the inspiration. Ever since I heard the Betsy baffles I was in love. Lii audio added the cutout diameter to their website. I believe it is 285mm.

I slapped a pair together Saturday night with some scrap plywood I found in my garage. These are  "test" baffles. I cut the driver openings 1/2" too big. Next time around I will use 1"instead of 3/4" plywood. Here is a photo.

Thank you for the compliments.  Your eyes are not playing tricks on you. I decided to mount the drivers at a 1/3 of the way from the top and 2/3 from the bottom. There are advantages to doing it that way.

Still working on break in, but they sound fantastic. I used a scrap piece of plywood for the baffles and some MDF stair tread for the bases. I spent less than $20 building them and slapped them together in less than four hours. To get the curve I used three drywall screws and a piece of PVC pipe. Just a quick and dirty "prototype"

It is not really a trade off. Offsetting the driver helps to smooth out resonance. Rounding the baffle helps with that too. The "1/3,2/3 rule" was borrowed from from the use of exiters. The distance of the driver from the floor can affect the bass response.  That can be tested by turning the baffles up side down.
