The night sooner than the events of January sixth in D.C., I found myself sitting on a small sofa contained within the workplaces of Linear Tube Audio in Takoma Park, Maryland. I had merely spent an exhausting day travelling down from New Jersey; getting the children organized in regard to highschool in my absence throughout the time of COVID-19 took far an extreme period of time. 

I had one toddler in Israel (now once more at SUNY-Binghamton), and two in school in New Jersey. Our faculty handled COVID closings greater than most, nevertheless we had been knee deep throughout the Zoom issue for almost 7 months.

Once more in Would possibly 2021, sleep was not potential on account of our eldest remained huddled in a bomb shelter as Hamas missiles exploded over her head south of Tel Aviv. Was not a superb week.

Fast forward to the middle of September and the Jewish Extreme Holidays and I used to have the ability to stroll proper all the way down to the seaside and start fishing until I caught one factor that I would drag home.

Life was that good. Yup.

Music has been previous important over the earlier 32 months.

I’ve on a regular basis been fascinated by open baffle, and single-driver loudspeakers nevertheless 2020 and 2021 had been very arduous years to get one thing like that for evaluation and there have been no reveals after the NYC CanJam which is targeting headphones. RMAF is kaput. AXPONA was pushed off for an extra 12 months and I couldn’t cross the Canadian border to attend the Toronto Current — and the Montreal Current in no way occurred.

Spatial Audio M3 Sapphire Audio system

Spatial Audio and Linear Tube Audio have labored collectively for years on the commerce current circuit and there’s some extreme synergy between their respective merchandise.  

Linear Tube Audio’s Z10 Integrated Amplifier is a extremely distinctive tube amplifier that solely outputs 13 watts of vitality, nevertheless blended with the open baffle Spatial M3 Sapphire loudspeakers, the usual of the sound is genuinely jaw dropping in the perfect room. 

Listening to a wide range of vocalists, I quickly forgot about the whole thing else occurring on this planet. The midrange was fantastically fleshed out and every single performer was ineffective coronary heart in-between the loudspeakers.

The LTA/Spatial Audio combination was not set-up in a extremely big listening space nevertheless the soundstage was remarkably deep and enormous.

Full-range single-driver loudspeakers have been spherical as long as the radio, and have been a definite section contained in the audiophile world for lots of a very long time; the form of product that has polarized listeners who each love their coherency and tone, or who detest them for a beaming top quality on the frequency extremes.

Detractors bemoan their limitations when listening to heavy metal, big scale symphonic works, or bass-heavy electronica, nevertheless my experience suggests one factor else; It’s dependent upon the room, driver/cabinet implementation, and what you ponder to be an acceptable listening diploma.

Over the earlier decade, producers equal to Omega, Manger, Spatial, Zu Audio, and Voxativ have launched the category forward with superior driver know-how, however as well as a model new aesthetic making them less complicated to place inside the home.

Open baffle loudspeakers work collectively a lot much less collectively together with your room which makes them (even big loudspeakers identical to the M3 Sapphires) less complicated to set-up. 

That being said, the Spatial M3s sound reasonably extra spacious ought to you possibly can pull them 3-4’ from the wall behind them.

In regard to vitality, my experience tells me that whereas chances are you’ll get away with 3-5 watts with a couple of of those loudspeakers, the usual of those 3-5 watts greater be very spectacular.

The Spatial Audio loudspeakers need at least 8-10 watts at a minimal. The M3 Sapphires are moreover 4 ohm loudspeakers and to allow them to cope with loads of vitality. I may not be afraid to drive them with a 50-watt amplifier.

The Linear Tube Audio Z10 drove the M3 Sapphires pretty merely throughout the small space and it’s a mixture that I plan on listening to as soon as extra.

If the LTA Z10 is exterior your worth vary, there are one other alternate choices that sound fantastic with these sorts of loudspeakers.

Decware provide fantastic tube amplifiers that sound phenomenal with these form of loudspeakers, and the prices are often not unreasonable.

The Decware Super Zen Triode SE84UFO2 is the true deal and among the many best tube amplifiers I’ve heard beneath $3,000. The prepared report is absurdly prolonged — I hope to see my mannequin by June 2023. The report is that prolonged.


The one scenario is that the Super Zen Triode solely delivers 2.5 watts of vitality.

They won’t be preferrred for the Spatial M3s, nevertheless they work fabulously correctly with the Klipsch Heritage audio system and one different mannequin of audio system that I’ve cherished for a couple of years.

If the Spatial M3 Sapphires are out of your worth vary, you may want to ponder the full-range driver loudspeakers equipped by Omega Speaker Systems who’re based in Connecticut.

“I constructed my first pair of loudspeakers as soon as I used to be twelve years-old using a full-range single-driver designed for a vehicle loudspeaker,” remarked Omega CEO, Louis Chochos

“There’s one thing about their immediacy, and the straightforward method that they convey that made me decide to start out out a loudspeaker agency in 2005. Full-range single-driver loudspeakers merely sound additional pure and reproduce the midrange in a fashion that connects you with the music.”

Omega Speaker Strategies wouldn’t be the first loudspeaker agency to utilize OEM off-the-shelf drivers, and its experience in that regard glad Chochos that he needed to design and assemble his private.

“Our earliest fashions used Fostex drivers from Japan, nevertheless when you’re a small producer and in addition you don’t order a whole lot of drivers from a vendor with loads of prospects, you will have little or no say as regards to the technical specs of a driver,” remarked Chochos.

“To compete and provide one factor actually distinctive that people would want to buy, we wanted to design various drivers in a number of sizes, with every Ferrite and Alnico magnets, and even experiment with completely totally different provides like hemp sooner than we had been comfortable that our drivers would sound good.”

Loudspeaker design is an expensive endeavor; the largest producers like Dynaudio, KEF, and Paradigm spend a whole lot of 1000’s of {dollars} on R&D, sooner than bringing new driver know-how to market. For a small agency like Omega, getting it correct with its private proprietary drivers was key to setting up its determine. 

Full-range single-driver loudspeakers don’t take advantage of a crossover because the one driver is attempting to breed as lots of the frequency fluctuate as potential; putting even bigger significance on the cabinet design and its have an effect on on the overall sound of the loudspeaker. Omega could assemble fantastic sounding drivers, nevertheless it does a good greater job with its cabinets which will be proprietary designs and by no means one factor you usually uncover at their respective worth elements. Chochos has been setting up cabinets for a few years, and his consideration to ingredient is obvious in every the engineering and finish top quality. 

Every Omega model makes use of triple-layer constructing, plus an additional finish veneer. Chochos prefers to utilize softwood MDF for the core, along with ladder bracing, and every cabinet is publish usual (veneered after the cabinet is constructed), so all edges are hand chamfered, filed, and faceted. Chochos believes that prospects are paying for the perfect top quality aesthetic, other than merely effectivity, so every Omega cabinet is veneered and accomplished on all sides. 

Omega Speaker Strategies Super Alnico Shows (SAM)

Omega Speaker Strategies provides various two-way shows, floor-standing towers, and subwoofers in various finishes; along with every EKO Teak, Olivewood, Ebony, and precise hardwood veneers.

The dearer Super 8 XRS, Compact Alnico Monitor, Super 3 Extreme Output Monitor, and Super Alnico Shows shall be ordered with furnishings grade Maple, Walnut, Quartered Macassar Ebony, and Zebrawood veneers that may not look misplaced in any room. Each Omega loudspeaker is made-to-order and Chochos is able to provide many wood finishes if the standard selections are often not distinctive ample.

Full-range single-driver loudspeakers are less complicated to drive than customary various driver loudspeakers, nevertheless they’re moreover very delicate to the usual of those watts. With a wide range of 92-97dB sensitivity, and impedances that infrequently dip beneath 6 ohms, Omega’s loudspeakers can work with amplifiers between 2-50 watts; my listening experience implies that 12-25 is the right fluctuate in a medium-large room with jazz, pop, classical, and even electronica. 

Tube amplifiers will be my selection with the Omega selections, nevertheless Chochos is quick to counsel First Watt from Nelson Pass, and one other solid-state amplifiers with a warmer tonal steadiness as easy ideas. 

“Prime quality over quantity wins the day with any of my loudspeakers, and based on the success that my sellers have had with Leben, Unison Evaluation, and Line Magnetic tube amplifiers, I really feel they work correctly with any electronics that emphasize tone, and immediacy,” replied Chochos.

That’s the wonderful thing about the single-driver loudspeaker. The simplicity. It has a lot much less probability of imparting a character sonically or musically on the effectivity, tone, and dynamics of the recording. It’s very convincing when carried out accurately,” 

If you go down the darkish path with these sorts of loudspeakers, you may in no way return to something.
