Tractrix horn

[DonBattles]

I'm thinking about adding a Tractrix horn to my Omega's. The unit I am looking at is the BMS 4524. Can I get away with just a high pass filter keeping the Omega's running full range or should I add a crossover?

Any input or comments will be appreciated :thmbsp:

Sure, you could add the horn with just a first order crossover (a cap) and leave the Omega just as it is. You could also modify the Omega network to remove the high end. This kind of begs the question: Why? You must have a purpose like reinforcing the top end that you apparently find lacking?
There could also be some downside to this like experiencing some comb filtering where the whizzer is reproducing the same frequencies as the horn, if allowing the Omega to work "as is". The efficiency of the horn and CD is going to be something else that you'll have to deal with, padding it down to mate with the rest.
I would be interested to know the objective in this as the single point source Omega seems to be a well thought out alignment.

Yep, just like westend said. You can do it, but I think it will sound better if you roll the omega off and let the horn pick up from there. I'be had the Sound Lab horns and they are built like a brick $#!t house.

Before the Omega's I was using some DIY back loaded horns with Fostex FE126's and loved the detail but felt they lacked the bottom end I wanted plus they were a bit harsh. I tried this set up with a sub but still felt the Fostex drivers were too in my face, so enter the Omega's. These have the bottom end I like but I feel I'm missing that sparkle. So maybe the Tractrix isn't the right solution. I love the detail of the Omega driver and the mid range and voicing is really sweet. Guess I'm just not sure what direction to take :scratch2:

Econowave. The Omega will give you a nice, efficient bottom end. If it were me I'd use the 18Sound waveguide with the B&C DE250. I'd make a separate, speaker-top box for the waveguide, CD and crossover, so's as not to modify the original speaker. The problem with full-range drivers is their collapsing directivity - build a full-ranger with solid bass response and, unless it's in a really big room, it'll sound bassy, and rolled-off. At least, that's my two cents.
