This design is a 1.5 OB Tower based on the 6.5'' Alnico drivers.   See Attached pics for details..

I had Louis design me a tower version of his 1.5 OB Monitors.   I owned these speakers back in 2015 but wandered away from them..   :duh:    To be honest, these speakers with a 45 SET were absolutely lovely.  The OB Monitors did require a subwoofer.   The Tower OB version will not (per Louis).  See attached.

Man...I'm gonna have to keep these in mind the next time I look to get another set of Omegas. These have really caught my attention.

As I understand, the lower RS5 is crossed over at 200 Hz.  Would love to road test these.

Lower driver is @500hz for the OB monitor and @200hz for the OB Tower.

Awesome!

How low do they go? You feel they don’t need a sub? I might inquire into a pair of these. Just beautiful

Where is the backdrop out the window?

Kray !

A sub will be needed..   its a 6.5 woofer.   Even Louis can not bend the laws of physics  :wink:

I am in the process of ordering a 18'' from Funk Audio.   The back ground is the Whitefish Mountain Range in Montana.

Even better tilted back !    Breaking in..   much stronger mid bass and low end punch.   Lovely speakers.  A step beyond the RS-5 OB.  I feel in a smaller room it is possible not to need a sub.

Glad to see you got them in a different room.  That first room looked awfully lively!  I bet they sound fantastic.

Dwight,

I'm happy the Omega open baffle speakers are working out.  They look stunning.

I would love to know what is feeding the Omegas. 

What amp/preamp are you using? 
What sub are you using.
And that audio rack.  Thats a looker!  What is that?


It looks like you have curated a killer set up!

Thetakeout,

https://www.audiocircle.com/index.php?action=systems;area=browse;system=2277

The steel stand is custom based on 2.5” maple for the shelves.   Weighs a ton.  Not fun to move !

The jfet preamp is diy.

The Alnico OB’s are excellent speakers but need to be at least 4’ from the back wall, otherwise the back wall reflection becomes an issue.
