Thank you for letting us get some feel of your system. I think I have seen a picture of your system before somewhere. I was wondering too how the sound would be to have a room as part of the speaker. Great job you did.Dear Tang
Thank you for posting this video. I believe David sent you this video to show where in the ballpark he is with your project. To me, it showed that a horn speaker can be without the vices usually associated with that type. Most of the videos I have seen about horn speakers left me veering towards the McGowan camp. Have I been wrong all this time? Then David Karmelli and you ( I have never met either) ,made it right again: A horn can sound the way it must. It can be a damn good speaker first and then add the elements thay makes a horn special.
In a way ,I started this video mess by posting a video because most people never heard a gigantic horn and few shall. In the end they should be just speakers that happens to be horns ,not some diabolical creation that somehow create a sound. Dave Karmelli gets that and for that the giants that became before us should be thankful.
As David mentioned, the baffle is tunable. A smart design. My room acoustic, phono stage and tubes I use are different from David. Adjustability will give me flexibility to optimize the sound. The Eleanor Rigby you heard was a "rounded sound." More density in the mid and low down. No tilt up. Less exciting sound but super smooth with tremendous presence from bass as oppose to a presence from the treble. Video below is a different sound shifting the tonal balance up a little while not hyping. I think tuning sound is about balancing act. You will feel more presence now from leading edge. Cello plug at the beginning. Magoni voice is great for checking the system set up from cartridge setting, power mgt, cables and speakers themself. Her sibilances will show more when things I said is less good. Good record for system check up purpose imo.
