The Attractiveness of Open Baffle & Single Driver Loudspeakers



The night before the events of January 6th in D.C., I identified myself sitting on a tiny sofa inside of the workplaces of Linear Tube Audio in Takoma Park, Maryland. I experienced just put in an exhausting working day travelling down from New Jersey obtaining the young ones arranged in regard to faculty in my absence in the time of COVID-19 took much much too substantially time. 

I had one particular baby in Israel (now back at SUNY-Binghamton), and two in faculty in New Jersey. Our faculty handled COVID closings greater than most, but we were being knee deep in the Zoom detail for just about 7 months.

Back in Could 2021, snooze was unachievable since our eldest remained huddled in a bomb shelter as Hamas missiles exploded more than her head south of Tel Aviv. Was not a incredibly excellent week.

Quick ahead to the middle of September and the Jewish High Vacations and I was completely ready to walk down to the beach front and begin fishing till I caught anything that I could drag household.

Daily life was that good. Yup.

New music has been outside of critical around the previous 32 months.

I’ve generally been fascinated by open baffle, and single-driver loudspeakers but 2020 and 2021 were incredibly really hard years to get nearly anything like that for review and there have been no exhibits following the NYC CanJam which is concentrated on headphones. RMAF is kaput. AXPONA was pushed off for yet another calendar year and I couldn’t cross the Canadian border to show up at the Toronto Display — and the Montreal Exhibit never occurred.

Spatial Audio and Linear Tube Audio have worked with each other for years on the trade display circuit and there is some serious synergy between their respective merchandise.  

Linear Tube Audio’s Z10 Built-in Amplifier is a very exclusive tube amplifier that only outputs 13 watts of electricity, but blended with the open baffle Spatial M3 Sapphire loudspeakers, the quality of the audio is truly jaw dropping in the appropriate room. 

Listening to a array of vocalists, I rapidly forgot about anything else likely on in the entire world. The midrange was wonderfully fleshed out and just about every solitary performer was dead centre in-between the loudspeakers.

The LTA/Spatial Audio mixture was not set-up in a extremely massive listening room but the soundstage was remarkably deep and wide.

Full-range solitary-driver loudspeakers have been close to as lengthy as the radio, and have been a specialized niche within just the audiophile globe for many many years the type of solution that has polarized listeners who either adore their coherency and tone, or who loathe them for a beaming excellent at the frequency extremes.

Detractors bemoan their constraints when listening to hefty steel, massive scale symphonic operates, or bass-weighty electronica, but my working experience indicates something else It relies upon on the space, driver/cupboard implementation, and what you contemplate to be an acceptable listening stage.

Over the earlier ten years, makes these kinds of as Omega, Manger, Spatial, Zu Audio, and Voxativ have introduced the classification ahead with superior driver technological innovation, but also a new aesthetic earning them much easier to area in the dwelling.

Open baffle loudspeakers interact much less with your space which tends to make them (even big loudspeakers like the M3 Sapphires) much easier to established-up. 

That being said, the Spatial M3s audio significantly a lot more roomy if you can pull them 3-4’ from the wall guiding them.

In regard to electricity, my expertise tells me that when you can get absent with 3-5 watts with some of these loudspeakers, the good quality of these 3-5 watts far better be very remarkable.

The Spatial Audio loudspeakers will need at minimum 8-10 watts at a minimal. The M3 Sapphires are also 4 ohm loudspeakers and they can manage a whole lot of ability. I would not be concerned to generate them with a 50-watt amplifier.

The Linear Tube Audio Z10 drove the M3 Sapphires quite very easily in the smaller area and it is a blend that I plan on listening to once again.

If the LTA Z10 is outside the house your spending budget, there are some other solutions that audio great with these varieties of loudspeakers.

Decware provide great tube amplifiers that seem phenomenal with these variety of loudspeakers, and the selling prices are not unreasonable.

The Decware Super Zen Triode SE84UFO2 is the true deal and one of the finest tube amplifiers I have heard below $3,000. The waiting around checklist is absurdly very long — I hope to see my version by June 2023. The record is that prolonged.


The only situation is that the Tremendous Zen Triode only delivers 2.5 watts of electrical power.

They may possibly not be ideal for the Spatial M3s, but they get the job done fabulously very well with the Klipsch Heritage speakers and an additional brand of speakers that I have beloved for lots of several years.

If the Spatial M3 Sapphires are out of your spending plan, you may perhaps want to contemplate the complete-assortment driver loudspeakers made available by Omega Speaker Techniques who are centered in Connecticut.

“I designed my first pair of loudspeakers when I was twelve decades-old using a total-variety solitary-driver developed for a motor vehicle loudspeaker,” remarked Omega CEO, Louis Chochos

“There is one thing about their immediacy, and the easy way that they communicate that made me determine to start off a loudspeaker enterprise in 2005. Complete-range solitary-driver loudspeakers just audio a lot more pure and reproduce the midrange in a way that connects you with the music.”

Omega Speaker Techniques would not be the to start with loudspeaker company to use OEM off-the-shelf drivers, and its working experience in that regard persuaded Chochos that he required to structure and develop his own.

“Our earliest models applied Fostex drivers from Japan, but when you are a little maker and you really do not buy 1000’s of motorists from a vendor with a lot of clients, you have very minor say when it arrives to the specialized requirements of a driver,” remarked Chochos.

“To compete and supply something genuinely unique that folks would want to acquire, we experienced to style various drivers in distinct sizes, with each Ferrite and Alnico magnets, and even experiment with various products like hemp in advance of we had been pleased that our drivers would audio superior.”

Loudspeaker design is an high priced endeavor the biggest brands like Dynaudio, KEF, and Paradigm devote tens of millions of pounds on R&D, right before bringing new driver engineering to market. For a little business like Omega, getting it appropriate with its own proprietary motorists was essential to creating its identify. 

Entire-array single-driver loudspeakers do not benefit from a crossover as the solitary driver is attempting to reproduce as considerably of the frequency selection as doable putting even larger relevance on the cabinet design and its impact on the total seem of the loudspeaker. Omega could possibly build exceptional sounding motorists, but it does an even greater career with its cabinets that are proprietary patterns and not anything you generally locate at their respective price points. Chochos has been building cabinets for a long time, and his attention to element is apparent in both the engineering and complete excellent. 

Every Omega design makes use of triple-layer development, furthermore an added complete veneer. Chochos prefers to use softwood MDF for the main, alongside with ladder bracing, and every cabinet is publish formed (veneered immediately after the cupboard is developed), so all edges are hand chamfered, submitted, and faceted. Chochos thinks that buyers are paying for the best excellent aesthetic, aside from just functionality, so just about every Omega cupboard is veneered and concluded on all sides. 

Omega Speaker Methods Tremendous Alnico Screens (SAM)

Full-variety one-driver loudspeakers are a lot easier to travel than typical numerous driver loudspeakers, but they are also incredibly delicate to the excellent of individuals watts. With a array of 92-97dB sensitivity, and impedances that not often dip below 6 ohms, Omega’s loudspeakers can function with amplifiers between 2-50 watts my listening working experience implies that 12-25 is the proper selection in a medium-significant place with jazz, pop, classical, and even electronica. 

Tube amplifiers would be my preference with the Omega choices, but Chochos is quick to counsel First Watt from Nelson Pass, and any other good-point out amplifiers with a hotter tonal harmony as simple tips. 

“Quality above amount wins the working day with any of my loudspeakers, and dependent on the achievement that my sellers have experienced with Leben, Unison Investigation, and Line Magnetic tube amplifiers, I think they operate nicely with any electronics that emphasize tone, and immediacy,” replied Chochos.

Which is the attractiveness of the single-driver loudspeaker. The simplicity. It has much less opportunity of imparting a character sonically or musically on the effectiveness, tone, and dynamics of the recording. It is incredibly convincing when carried out appropriately,” 

At the time you go down the dark path with these kinds of loudspeakers, you could by no means return to anything else.
