Open baffle speakers


Open baffle speakers design is the simplest , to get bass response similar to other design , like ported, the baffle size must be huge to avoid low frequency degradations . Tipical size the baffle   width 10-20"  got weak  bass performance.   I am wondering how open baffle speakers design became so popular ?

I am getting an open baffle speaker in Dec. Do not know the name of it yet, but I heard half of it as a prototype in June (bass was missing). I have a lot of faith in the designer. I will be getting the smallest version which is made for recording studios monitoring consoles. That will also work on an office desktop though I will use stands.

My friend told me that his new speaker sounds better than my Yamaha NS5000 speaker that he heard and loved with my CODA #16 amp. I have my doubts about that but if it is in the same ballpark then that would be a home run for my office. His speaker can be driven by 8 watts so I will use the Schitt Aegir 20-watt Class A amp (for now).

 

 

 

I went to my friends Danny's place in Ventura, CA he is the owner of Requisite Audio. He is also a musician and has the best ears for audio of anyone that I know, genius level hearing and also commented as such by Stajan on an article on 6moons.com.

He told me his new creation is the best speaker he has ever heard. Now I know he does not BS but still it was his baby, so I had some doubts.  He had come to my place a year earlier and heard my Yamaha NS5000 with my CODA #16 amp and said that was the best box speaker he had heard in about 40 years.  I have it in a nice room with very little side reflections and a high ceiling.

When he told me the open baffle speaker he his creating sounded better than the NS5000, especially on the bass I was surprised. Yesterday, I had 4 hours available while I had to go to LAX to pick up my parents. I spent that time at his place listening to the smallest iteration of his new speaker. His place is not ideal for a demo of speakers, he will set up the top end model at his shop in Ventura soon. However, this demo reminded me of a demo of a DAC and amp by what is now Infigo Audio about a decade ago. They used a $500 used scratched up B+W speaker to demo the DAC (and amp). Even in a non-deal setup great sound was possible.

I had heard an open baffle system, that cost $160k for the speaker alone, at a local store and thought it was not better than the NS5000.,which they also sold. I was not blown away with the idea of open baffle based on that experience. That is until yesterday. What I heard yesterday was a very fast, detailed, and explosive speaker, The demo was one where I was either toe tapping or dancing to the music as never before in a demo. I had also taken my superlative Schitt Yggi+ OG DAC to his place to listen with it so that had something to do with it.  That bass was extraordinary and Danny told me that is what bass should sound like. He was a professional bass player for decades.

I listened to jazz, Mozart, rock (specifically Roller by April Wine).  There was something special going on with the open baffle design. He had a class D on the 15 -inch woofer and a device to control the top end from a 15-inch full range driver. That full range was driven by a Felx Envy 4-watt amp with $2k+ of tubes. The customization of the balance between the top end and the bass was all done on the analog domain. Normally, I would say digital was the way to do that but what do I know after hearing this.

This maybe the best speaker I have EVER heard. The wife may be a no go to having 2 speakers in the same Livingroom. I also need some cash to make this happen. 

I asked Danny if he would sell the NS5000 if he was in my shoes. He said he would not since it is so good, but he also said he will no longer listen to a box speaker. I totally get that sentiment now.

Due to space restrictions and the wife factor, I think I may be selling my NS5000 and the CODA #16 amp (or my Sanders Magtech amp) to get this speaker. I love the CODA amp and can use it in my office with my Magnepan Mini. I am getting the open baffle speaker but not sure about selling the NS5000.

The web site in not updated with the new open baffle speaker. He is expecting a December release with many customization options from a 2-driver setup to a 5-driver setup. For my Livingroom his 2-driver speaker would be good, but the 3-driver is ideal. I am getting the 3-driver. The customization is for extra bass modules, fancy finish, 2 levels of driver quality. I heard the lower end driver he will sell. I will likely go with the unheard higher end driver and bare bones finish.

He will offer me a discount, but I never take discounts from my friends since this is their livelihood.

 

 

 

Spoke with the wife about keeping 2 speakers in the Livingroom. She says she does not care and go ahead. Nice. It will be great to be able to do a head-to-head with the Open Baffle and the NS5000.

I met up with my friend who is designing the new open baffle speaker I am interested in. I noticed that he had his setup almost the same distance as I sit in my office (near-field). My office is the second floor of my home overlooking the first floor. With an open guard railing that makes the room seem sonically bigger.

After some discussion we came to the conclusion that the 15-inch top driver + 15-inch bottom driver configuration will work in this space. He will have smaller configurations but the 15-inch one is the one we listened too, and he said to go with that. The reason being that this system has a configurable bass and the bass dispersion pattern of the speaker is a figure eight shape. 

So that means I can get speaker to work in the current space and a future space when I eventually move.

Unfortunately, this is not going to be cheap, and the following items are going up for sale.

  • RAAL VM-1a tube headphone amp
  • CODA #16 amp
  • Audience FrontRow speaker cable
  • Sanders Magtech amp
  • Magnepan Mini speakers
  • KEF KC62 sub

 

 

@coltrane1 the one I am getting is still not released but I heard it with a Felix Envy 8-watts (maybe less) headphone amp. Only issue for me is that I will take a slight hit in the quality of amplification for the speaker that currently is driven by the #16. I am thinking of either the Schitt Tyr or Wutan for that speaker. It is a trade-off I am willing to make.

@coltrane1 I have read posts with people talking about Don Sachs, Decware, Dennis Had, et al. I never paid too much attention since they did not work for my power-hungry speakers, Magnepan Mini and Yamaha NS5000. However, now with the open baffle that I am getting a new world of listening opening up.
