Very nice! I enjoyed watching your evolution to what you have now in a baffle-less OB. I'd love to hear them. There are a lot of armchair designers but not a lot of people actually experiment as you have to create the sound that you like best. BTW, those woofers look amazing!
I have got to say you have tried so many open baffle arrangements, very impressive journey. Re your final system, i am curious how much eq you had to employ in the mid/ high array....briefly, where were the big compensations in frequencies you had to make? Thank you so much for such intriguing videos.
Yes....these are best so far. AE's were ok for jazz type volumes, but they are relatively delicate with light cones and only 150Watts continuous rating, vs the UM18 1000Watts. However, when you factor in efficiency of the of the AE rated at 96db, vs the UM18 88db, they should be 3x louder. I didnt find this to be the case at sub-sonic frequencies where they were totally trounced by the UM's.
Assuming you're not measuring near field, you have a 10dB broad bass peak another 8dB broad hump in the presence region and a lobing treble region that slopes down very sharply too early. This is clearly audible and I'm amazed you're happy with this. Do you consider these speakers as finished or is this still in development?
Carlos, I am amazed you can hear lobbing, broad bass peaks and humps in the midrange though a YT video!! You need to get a job with NASA as you are being wasted merely commenting on here. Hopefully, some one will notice you!
@@vangelo2252 in fact he's not all that wrong. but what he points out just adds to the character of the system,it can actually add a lot of resolution and presence. however what carlos calls lobbing,which is not as lobbing is a completely different ball game, is odd cancellation between the front and the rear acoustic pressure of the drivers. which is completely normal for this topology. may be a high frequency array can extend the high frequency all the way to 35 or even 40 khz air motion transformer or planar cheers
Soundstage is fantasic. Very natural sounding. Quite an accomplishment.
Sooo naturally sounds! A perfect tonal balance and no a trace of MDF cage. The only thing is that a guitar was huge
I have heard these speakers and the sound clip just hints at what they do.
Thanks John.....we both know they rock!

can I ask you how much the complete build cost (amp included) please ? i have never been so amazed by speakers
More videos please🙏
Amazing
Killer work
Sounds nice

Amazing.... It's all I can say.
After such an epic loudspeaker journey, how do these current speakers compare? Are they the best so far? Why did you drop the AE woofers?
Yes....these are best so far.

@@TransFiAudio Which AE woofers were they? I'm guessing not the IB15AU or IB15HT or I'm surprised there would be improvement going to the UM18.
For sale?

Just out of curiosity how can you tell that these speakers have those problems threw a UA-cam video. Not trying to throw shade just curious.

I agree it sounds a bit dry, the vocals sound like it is stuck at the throat.
@@claytonmckeon9872 I looked at the graph. Did you not watch the video to the end?
They might sound great, but I couldn't put speakers that look that awful in my media room.
... eye of the beholder
besides, form follows function
