Title: Lii Audio 15 Baffles - To Tilt or Not To Tilt
Post by HockessinKid on 03/31/20 at 13:07:30

Greetings All,

After reading about Steve's findings about tilting back his larger ZF15M & L baffles 7 1/2 degrees I decided to experiment a bit.

Putting some standard rubber door stops underneath the front off Randy's baffles resulted in a taller soundstage but I did not like the loss of lower end energy. The balance was off and the sound was lean to my ears. Probably a 10-12 degree tilt.

Next I placed two Gingko Audio Arch 1 resonance devices under the front of the baffles. I have primarily used these arches underneath my Omega XRS SAHO speakers to tighten up bass response. They raise the front of the baffles about 5 degrees (1 1/2 inches). †Well bless my soul, the same frequency balance but a larger and deeper soundstage. These little babies worked some magic that was completely unexpected.

So I going to keep them in place! †BTW, my Modwright PH 9.0 phono preamplifier tubes and capacitors have settled in nicely after about 50 hours. I'll be posting a small review elsewhere on the forum.

Cheers,

HK

Hi HK. Can you post a picture of the arch under the speaker? Sounds like a great idea.

Hey guys,

Roger ..... thanks for the heads up !!!
I have had mixed results with placing various cones, spikes, etc. under the Betsy and Lii 15 baffles .... your solution might be the "magic mushroom" .....

I will definitely give this a try .....

Happy listening,
Randy

I raised my Lii 15 baffles about 3/8 of an inch in the front using printing paper. It is not necessarily a permanent solution but in my room, the height  was the best compromise between a better sound stage and bass output. I do not sense a lack of bass at all at this angle.

Iím trying to envision the placement under the speaker. Are you using 2 per speaker? With the curve running front to back?

Geno,

Two under the front of the speaker, oriented front to back. Easy, peasey.

I see. So you can increase the angle of the speaker tilt the further you push the arch back.

Sorry for the 101 questions, but roughly what are the dimensions of each arch? W x L.

Geno

About 2.5" W & 3.25" L. Not very large. Heck if I know what materials they used to build them.
