Lii Audio F-15

Any suggestion on a good source for “affordable”/inexpensive non-ferrous binding post tabs?

In planning to replace the ferrous posts on my Lii 15 drivers, I noted that many of the tabs I have from several different Parts Express kits are ferrous, the posts aren’t, but most of the tabs ARE. Doh...

A friend of mine built the OB's, he's a woodworker and first attempt at it... I'd say he did an amazing job. Solid walnut here. He's interested in doing more if anyone else is interested (PM me)

They are different sounding than the Omega Super Alnico's, but I've been playing around with positioning, which they sound different everywhere they are at... but this near field setup is pretty sweet.

Kray,

I would love to hear an update on the Lii 15's. Are they still in the system? Do they compare favorably to your Omega's? I would love to hear how they are settling in or if you moved them up the road.

Well my update is interesting...

They broke in nicely. couple of points:
- for me they need LOTS of open space, close to walls was not ideal, but place them in a big open room and they shine.
- I preferred to have them tilted up, I felt I was missing something with the centers being so much lower than ear height
- Omega's are special, there is just something special about Louis 6.5" AlNiCo driver that is hard to beat.

I ended up selling the Lii's because I was/am moving, and my new audio room is way too small for the Lii's. Not a long detailed update but that sums it up.
 
It's somewhat troubling to hear that two of our members have now sold their Lii 15's and moved on.
I have never heard the F-15's, but if they are anything like the F-12's that I sent back, they have a definite sound quality that it seems
will be loved or not. It surprises me to hear from the fellows at the controls at Lii Audio that they loved the classic Alnico vintage drivers so much, but their F series sounded so different to me than what I have experienced sound wise from the vintage Zenith's. My F-12's sounded hollow and cold to me. Definitely different sound tastes exist:)

I agree... I was so use to a Alnico driver, and just thought there was something missing in the F15, definitely not night and day, and if you never heard the Alnico the F15 would sound great. But YMMV
 
I also had a pair of f-15’s fall in my lap. I had some baffles that I did a quick experiment with some 10” Zenith’s that I used. Removed the wings, cut 15” holes and added some angled support legs. The wood is only about 5/8” thick and had a bit of resonance so I had to add some damping material to the back. This was just a quick and dirty test to give me a taste of what to expect from these. If I end up liking them enough to go further I will find some butcher block for a more permanent baffle. There are dimensions on the Decware website for Steve’s baffles. With your ob experience I am excited to see what you come up with and your impression of these compared to your other ob speakers.

I've looked at those figures as well as the ones on the Lii audio site but they don't seem the same although my eye sight is not the best. On the Lii Audio site I see 360 mm which is 14.17 inches???
 
I ordered a pair of F-15's in Feb. but they haven't shipped. Lii Audio has sent me several emails apologizing for the delay and even a pair of free F-6's. They claim the F-15's I'll receive are an improved version with better magnet material.

I've built these tilted F-15 baffles and have some smaller ones to try as well. I stayed within the 2.2 rule of thumb on baffle width but can cut them down if need be.

I just measured the paper pattern I used and it was dead on 14”, mine are rear mounted, but I did verify that they mounted in the hole.
Hi Madman1,
What were the 10 inch Zenith's that you had? I recently snagged a nice pair of the 1043's, but have not received them yet.
How did you like the sound of the ones that you have, and how did they compare with the F-15's?
 
Finally received the F-15s after a 3 month wait. I don't think they are broken-in yet but I really like what I'm hearing. Much larger sound stage and more immersive than my Zeniths which have more on top due to their double tweeters. Placed directly on the floor doesn't compete with them sitting atop the H-frame Alphas which gives them some really nice bass weight. I haven't tried them in the big wide baffles and may not as the sound is so good in this configuration. Lii Audio sent me an email saying that these have a new improved magnet material vs the older units. I see where others are running their F-15s in parallel with the Fast 8s with no crossover which I find intriguing. Seems like they would be competing with each other and lack that point source charm? I'm driving these with 2a3 Bottlehead mono blocks while the Eminence Alphas are powered by a 100 watt plate amp. Takes forever for the old Bottleheads to warm up which tries my patience but the wait is worth it. I do have a Decware Zen on order which may not arrive until 2023. Also plan to try my Dennis Had Magnavox with the F-15s.
