Post Subject: Upper-bass horns and current measurement.Posted by boiklox on: 1/16/2014

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on this site. And thank you for your response.
My objective is to create a system that is able to emotionally re-create music in a powerful and realistic way. My greatest memories are playing in orchestras and sitting in the middle of the violin section with a hundred other players on stage creating music and being completely engrossed by sound. It's magical. That is what I am starving for in my playback system. My system has been organically growing the past two years. The first "ah-ha" moment was vinyl, then tubes and now horns. So I think (I hope!) I am on the right path.
In response to your comments about my to dos (and thank you, a lot of things to think about).
For the time being, I think it is important to be able to arrange the speakers: Woofer -- Tweeter --- Midrange, so I will have to build a bracket to elevate the 2445 up about 12-16", this will let me position the 2405s at ear level, underneath the midrange. And I want to position the VC of the tweeter in line with the midrange. I'll plan on putting some foam on the underside of the horn and on the top of the woofer cabinet to absorb some reflections from the tweeter to these surfaces.
Upper bass is the next project for sure. That will likely give me the biggest "bang for my buck" so-to-speak. Any suggestions on what I should do there? Agree with you about this channel being the foundation of the playback system. Could my JBL 2226 work for this? Or should I consider another driver. You use the Fane Studio 8m for this purpose, correct?
Here is a measurement (gated in-room at 1m) of my current system (without tweeters). The 300b SET amps that I have currently, I like a lot. The output transform has a 8 and 4 ohm tap, I'm not sure if this is what you mean.
