Music with the Duet15 Open Baffle Speakers is open and big, even in small rooms. Absolutely no compromises on tonality and music presentation.

In this blog post I want to feature a project that I built recently for Don Sachs of Don Sachs Audio. Don approached me a while ago looking for his "End Game" speaker and decided that something custom would be required since there was very limited selection in the market for a horn loaded open baffle speaker. I went t

When I was much younger, I thought loud speakers were boxes. That was why you called them boxes. I build quite a few. And was reasonably happy with the results. Then I bought 4 huge and old Electro Voice SP15B on E-bay. They sat there for a while, getting older. Did not really know what to do with them. Make a bass unit? I already built a Klipsch Eckhorn. You do not need more bass ever egain... While my tube amps were getting smaller, i needed more efficiency. Horns! Yes. The Klipsch already was a horn. That would do well with the rest... I also liked the idea of an open baffle. I listened to one (not two) in Holland. What's stereo about a piano or Norah Jones? Got hooked. Can you combine these two? An open horn? Using a small Fostex all range, the sound was amazing... It does need the Klipsch though... Here, next to the BOX boxes... The horns win. And I still thought I needed 40 Watts or so... Still the EV's were looking at me all the time. And at Vivienne. Are you going to do something with these things one day? The answer was: yes. One day. Julia is a great artist. We decided that she'd paint the horns in wood. She went to a special school in Brussels, the only one in the world, I believe, where they teach this art. The results are amazing. She can paint anything in wood or stone motive. Unless you put your nose straight on to it, you can not make out the difference. That took a while. But, once finished... The result is astonishing! The next speakers in "marble"? No problem for Julia In the mean while: A good reason to attack the EV's. The EV's go way up in frequency... I onlyx needed a food tweeter with a reasonably low change over point. Fostex again. Then cut out some wood. Mounted it all. And presto. Absolutely impressive. Don't need the Klipsch anymore with almost a square metre of low... And the 1 Watt is more then enough to have all the volume you ever need. Then I found these very old speaker in a junk yard.... Opened one with nobody watching.... Isophon. All paper. Nice. Bought them both for 20 Chf. Apart from the tweeters they worked fine. A new baffle was all that was needed to make these auditorium worth. Daniel again. In Wallnut no less! I even use the old filter, all hand made... And with the 30cm woofers, with "wizzer" no need for the Klipsch either... There is still one pair waiting to be finished... Well 2 pairs actually. A pair of loud speakers is always worth having lying around. You never know....

The concept is Open Baffle loudspeakers. It has no box. And that's the genius. Almost all loudspeakers have more or less a "boxy sound". Even those who cost +10.000$. An open baffle gives an open sound. Very open. The downside is that you need at least twice as big woofers to achieve the same amount of bass.

This is my favorite ‘full range’ speaker even tho it’s not really full range. It gets nearly everything right – but you must modify it in order to smooth out its roughness a…

* disclaimer: world's simplest two way active open baffle I've just finished the test baffle for my new bedroom speakers and I couldn't be happier with them. I call them Bobette because they are the sexy younger sister of Bob, my main speakers. The entire speaker is made out of one piece of folded perspex. Drivers are the

PureAudioProject just confirmed that its latest Trio15 configuration is now available for pre-order. As Ze'ev (Wolf) Schlik, the founder of the modular speaker company explains, the Trio15 Coax10 project is a step closer to the realization of its original vision. "For a long time we were aiming for a three-way Open Baffle Speaker made right; and with 2020 coming to end we are excited to announce the addition of Trio15 Coax10 to our Trio15 line."

Doubling the number of woofers provide further +6db of maximum output. Basically they are vertically-stacked W-Frame open baffle speakers. The arrangements allows the front baffles to be kept narrow. Follow the discussion at LinkwitzLab forum here. There are some cosiderations that needs to be investigated carefully, for example the effect of gravity to cone acceleration.

The Trio15 Classic Open Baffle speakers are an interpretation of our Trio15 Speakers in a unique, elegant, pre-build open baffle wooden enclosure.

This is the open baffle system that I have been listening to as of late. These beautiful condition Electro Voice SP12B 12 inch full range speakers. Extremely efficient and without a crossover connected to a single ended tube amp, these speakers project a huge sound stage that has got me hooked. I would like to get two more of these and make a new baffle for them, so two speakers in each baffle.

How big does your room need to be for open baffle speakers? My room is 4.7m wide x 3.9m deep and works quite well. I wouldn't want to go muc...
