I have been interested in Hi Fi for 1979 and my first decent set up. i have made several box speakers over the years with "ok" results. recently i have been considering the open baffle set up but was put off with all the talk of reflections, dipole cancellation et etc.. I really REALLY wanted to do away with any sort of box and for that matter - baffle. thoughts of improper "colouration" seemed it would still be there. my conclusion was to try closed clamshell configuration {isobaric with no box or baffle?!} and although i experimented with small full range units i believed something would still be lacking, because of that trapped air between units. then i came across this story on "circles of doom". i read it all and was smitten. i have bought four new half decent 18" units and am in the process of assembly now. i am in two minds to try the "hyperbaric" spacing on the midrange/treble as used on the tiny speakers sold for the model train engines. all in good time ..

Hi very excellent video indeed I was really looking for something of the kind First of all my sincere congratulations I have some comments Two actually 1) i really think that a high pass filter should be applied to the arrays If you send to them also the low Hz the IMD will increase for sure 2) have you considered a D'Appolito arrangement for the drivers in the arrays ? i mean with the smaller drivers placed in the middle of the arrays ? disclaimer I love D'Appolito concept immensely Thanks again and kind regards gino

What is the cost of the loudspeaker?

This is out of the box design, very literally

Thank you for all you have done by expressing your creativity through experimentation and implementation. I lament not being able to buy a Salvation/Terminator rig while you were still in business. For the money I can't think of a comparable player that could compete as I still read of positive comments from still enthusiastic owners. Wish you could come up with something new based on everything you have learned so far.

First time I hear big, pure sound in basic room . Very impressive

I am so intrigued at this moment.

Очень хорошее звучание. Вот к какому звуку надо стремитья. Интересно как они отыгрывают другую музыку, джаз, блюз, рок.

Your link isn"t working by the way.

Fookin eck, they're mental. Amazing work mate.

CLARITY 😂IS AMAZING IN FULL RANGE,,YOU NEED A GOOD STEREO MICROPHONE TO GET ,,NO BOUNCY SOUNDS OF WALLS,,CHAIR, 🎉🎉🎉🎉🎉 PLAY "GEORGEO" HITS OF 1970S 😅😊

The best baffle is no baffle. Took you a while to get here, but welcome to the club. Your bass is still subject to distortion, but it is better than a lot of other methods being used.

Garbage thing

Im confused with those 18 inch subwoofers just mounted free air like that. Won't that just end up with a ton of cancellation?

Amazing

Is is this your reference sound for testing?😶

The most underrated kinear tracking arm ever!!!!?.

Horrible music.

You have created an open baffle bass section (dipole) with a point source mid-high section (omni). May I suggest a next step: to use 4 KEF 3001C's, two per channel back to back in counter phase to also create a dipole mid-high section? I did this experiment with 4 KHT 2001's: The imaging becomes a lot better than with two individual KHT 2001's running as omni's! I might even remove the backs and the ports to directly drive the 2001 woofers and tweeters in bi-wiring mode.

Late to this party…just wanted to thank you for confirming what I’ve been experiencing with zero baffle. You have a tremendous amount of experience and knowledge compared to myself. Good luck to you!

Hi. Thanks for sharing all of your buildings and tests. I spent a great deal of time checking everything that you did. I have finally built similar bass unit's and can confirm it's amazing. I use 18" RCF drivers. Many many thanks for sharing. I have the 18" on behringer as you to 95hz then two sets of 4 x 8" scanspeak isobaric traditional sealed towers from 70hz to 800hz passive on traditional xover then a pair of original Heil AMT tweeters from around 750hz. Not sure if you read these comments but if you get a chance to hear ESS Heil amt's try them i am sure that you will love the sound.

oh sweet lord

Imagine how much that system cost, wow

Congratulations ! This is power energy ! The sound is amazing !

These look amazing i would love to actually see how they are built, and some better detail, maybe a description on how you did everything….. they look really nice thanks for sharing

Nice speakers. Thanks for sharing. That music does not tell us much about their ability. I see the bass units running to the limits of their excursion but I just don't know if I hear it. If you play a natural well recorded acoustic piece with full range covered, we might know what these can do.

Very cool setup. I found your stuff just recently when I was looking for open-baffle sub designs. I've been a fan of open baffles for a while, but now I have to try this baffle-less design I think!

HELLO ; KIRK HERE. THANK YOU FOR SHARING THIS AMAZING "DIY" SYSTEM. I'M ALWAYS TRYING TO IMPROVE SOUND FIELD AND SND. DYNAMICS. I TRULY THINK YOU SHOULD ( PATENT) THIS DESIGN AND CONSIDER RETAIL MARKET !! THANKS A ZILLION ; KIRK'OUT'PEACE

What exactly did you do to the Kef 3001s? Please help me understand.

Re

Great setup, what is the song name or album ?

I would like to hear some normal music on this, like"Keith don't go" or "beautiful life"

Super sound

Great work, thanks for the inspiration. I'm planning to buy UM18s in the next days and start building my own monster. Most likely with Quad ESL in mid/high. I saw you went active. How did you deal with potential timing issues between the woofers and the speakers?

are the subs wired out of phase?

Very nice. Great build. More no baffle than Open Baffle. Sounds good but no justice to sound when played back on a PC watching a youtube video.

What's the purpose for woofer face to face? Wouldn't the back wave of the first woofer just cancel out with the front wave of the 2nd woofer? Doesn't look like the isobaric load either. Does this improve sensitivity?

Hi, I am building a similar setup. Please could you explain you 18" woofer mounting. it looks like it is floating how did you accomplish this please?

Very interesting

Turntables and speakers. You can build your own for 1/10th the price. DIY something like this for $3k, don't pay 30k. Open baffle speakers for $1200 in parts will sound better than anything under $20k.

When will you bite the bullet and redo the subs using the Dayton Audio Kraken 21" subs? That would be a revelation to hear.

Hi. Interesting solution! It's without crossover, what a scheme connection?!

bravo ! speaker mis is faithall ,no?

Those things are straight up prototypes to KEFs top of the line Blades. Thats why they're so oddly over engineered. Their siblings the 3001SEs became the LS series.

"Cheese burger cheese burger cheese..." Awesome lyrics!

Do you offer plans to build such spesker I have no crossover experience can you share crossover file

Excellent design and demo! Aaahh just imagine what those subs can do if they had a box. Dj magic mike feel the bass baby😂

And did you try to turn the 18 elements other way magnets facing other magnet ?

Have you done DML speakers ?

Very beautiful! Best speaker !
