The most realistic-sounding speakers ever? Indulge your wildest audio fantasies with these hear-it-all wonders.

Omnidirectional speakers have had a cult following among music lovers ‘in the know’ for years. Why? Because their wide-open 3D soundstage transforms your room into a huge concert venue. Traditionally they have done this at the expense of the pinpoint detail, but now you can have both! By using a Digital Signal Processor (DSP) between the front and rear drivers the LFR series of omnidirectional speakers have both a wide-open 3D soundstage and pinpoint detail. They provide the most immersive, transporting musical experience you have ever experienced.

When our LFR omnidirectional loving customers challenged us to take things even further, we were intrigued. We decided to take the DSP control from just the front and rear to all five driver groups and create the LFR1100 Active. The Active version of the LFR1100 loudspeaker creates even more accurate playback than the standard passive version through more detailed control over the Family of Amplitude Response Curves. We were able to make the Sound Power curve and the Listening Window curve the same and the results from doing this were beyond our wildest expectations, the realism of the sound is scary! It also plays louder and more dynamically through the elimination of the passive crossover networks.

Each speaker has its own DSP, tightly controlling each driver group to give you unprecedented dynamic range. Voices are crystal-clear. Cymbals shimmer and bass can be felt, not just heard.

LFR1100 Curves

Axiom's DSP
Axiom's DSPDSP, customized for the LFR1100 Actives

There is one DSP included with each LFR1100 Active (two per pair). It has one input (RCA or XLR) and six outputs (RCA or XLR) which separate the information sent to each of the five driver groups in the speaker along with an optional subwoofer output for each speaker. The outputs are designated for each driver group. By clicking on “More Finishes and Options” above you can have a set of 14 cables made-to-order in whatever length you need. This custom set of cables is color coded to make it easy to keep track of all the wiring.

The DSP included is in a stand-alone case. The input to the DSP is connected to the output of your pre-amp, receiver pre-out, or AxiomAir Transformer. The AxiomAir Transformer gives you music streaming via AirPlay, Spotify Connect, TIDAL, and UPnP. You can also store songs on a USB Drive or NAS and control the playback from the AxiomAir App. It has both an Analog and Optical input for other sources like a Turntable and TV. For those who are into Karaoke you can plug the AxiomAir Karaoke Module into your Transformer and control the music and microphones from the AxiomAir App.

The LFR1100 Active provides serious sound power: the amount of energy radiated into the room from 11 drivers will blow your mind! The front baffle features three High Powered 6.5-inch woofers, two 5.25-inch midrange/woofers, and two 1-inch tweeters, with our signature vortex port in the bottom. The rear baffle adds three more vortex ports, two more 5.25-inch midrange/woofers, and another two 1-inch tweeters. If you haven't guessed already, it takes some serious amplification to drive these speakers! A total of 10 amp channels of amplification, in fact: 5 channels per speaker; front HF, front MF, front LF, rear HF, and rear LF all need to be powered separately and it makes these speakers truly sing. We have three amp power levels to choose from, all available in a 5-channel version to run each of your LFR1100 Active speakers: The ADA1000-5, ADA1250-5, or the ultimate ADA1500-5. You will love the dynamic range you will experience!

Questions We Get All the Time

If my room is an unconventional shape or I need to place my speakers close to the back wall, will the LFR1100 Actives still work properly?

Absolutely! The included Digital Signal Processors (DSPs) have a Boundary Compensation control to allow you to tailor the information from the rear drivers to suit your environment. For placement close to the rear wall, experiment with the NEAR settings. If one speaker has no rear wall behind it, choose one of the FAR settings for that channel. The LFR1100 Actives have an uncanny ability to work with your listening room, rather than against it, in part because of the omnidirectional spread of sound.

What are the main differences between the passive and active LFR1100s and what can I expect to hear?

Removing the passive crossovers from the LFR1100 and directly driving each section with a dedicated amplifier gives us full control over the operation of each driver group. This in turn means that we have the ability to tailor the overall system to produce an ideal Family of Amplitude Curves. Another important benefit of the LFR1100 Actives is that removing the passive crossovers also removes a source of distortion and losses, meaning that the entire speaker has a higher sensitivity for better detail and dynamics. These things combined allow the LFR1100 Actives to deliver more clarity, revealing fine details in your favorite recordings that you have never heard, along with stunning dynamics, impact, and bass control that will shock you with well-recorded drums and percussion.

The LFR1100 Active DSPs offer both RCA and XLR connections, which should I use?

With a system that involves as many low-level connections as the LFR1100 Actives, much of the conventional wisdom regarding connections and wire lengths no longer applies. If your receiver/processor/pre-amp and power amp(s) have balanced XLR outputs and inputs, we recommend using XLR for all connections as it will reduce the likelihood of ground-induced noise and the overall system noise floor. Regardless if you are using RCA or XLR connections, all interconnect cables between the DSPs and amplifiers should be of the same type and identical lengths and all connections should be XLR OR RCA, not a mix of both.

With two DSP chassis and two or more amplifier chassis, what is the best way to place them?

Ideally your equipment rack or stand will allow each component to be placed on a dedicated shelf with adequate space above the amplifiers for cooling. If the components must be stacked, we recommend placing the amplifiers on top of the DSPs to allow for proper ventilation.

I am now 7 months into my active LFR1100s with an ADA-1000-2 driving the woofers and an ADA-1000-8 for the rest. I continue to be amazed with how sound pours out seemingly unrestricted at any volume level. With most recordings, I am unable to tell sound is coming from two speakers; the speakers are acoustically invisible. With well-recorded music and louder volumes, I experience immersion. It's not uncommon to hear sounds originating behind me. My M100s were 1080p and the LFRs are 4K.

I've used the active LFR1100 in my 1900 sq.ft. living room and 4200 sq.ft. A/V room. In what is a first for me, these ultra-dynamic, highly resolving speakers have not needed Audyssey room correction in either of these acoustically-challenging spaces. These, with Axiom sealed subs fed off the DSPs, give me a large soundstage with crisply-defined images and accurate, articulate acoustics from infrasound to near ultrasound.

- Hans
The M5s, M100s and active LFR1100s are skillfully-crafted, high fidelity sonic holography engines that carve out a 3D space and sculpt acoustic images within. The active LFR1100s are considerably more refined than the passives and offer greater stage width and depth (right out my bow window), improved image placement precision, higher image spatial and acoustic resolution including more "black space" between the images, improved quantity and quality of bass and mids which must be heard to be believed (they sound better than my passive system with three Axiom sealed subs), improved macro and micro dynamics and an enhanced ability to acoustically disappear particularly with high quality recordings. The active LFR1100s add up to a more emotionally satisfying experience than passives at not only high SPLs but also lower SPLs where passives only start to perform. It really is nearly impossible to go back to traditional speakers after listening to the active omnis. The technical differences between the passives and active omnis are transparently revealed in the frequency response curves on Axiom's product pages. As one moves up the line of products, the listening window and sound power curves extend further across the audible spectrum, are more linear, and closer aligned. The active LFR1100s offer a textbook example of aligned listening window and sound power curves that decline at 3dB per decade and are free of acoustic resonances. Such a speaker response is impossible to realize with the inherent limitations of passive cross-overs used in traditional speakers. Use of digital filters enables bespoke roll-offs to optimize driver integration and linearize mid-band response. Unlike traditional passive speakers, the filters are located upstream of the amplifier resulting in higher speaker sensitivity, improved stability in the response at higher power levels, lower thermal noise and improved control of the drivers. The result of this implementation is a speaker system that "plugs into a room and plays" with no EQ required and effortlessly renders the performance the sound engineer intended.

I have had the pleasure of owning the LFR-1100 Actives for two months and still have that ‘kid in a candy store’ feeling whenever I sit down and listen to them. Words do not do them justice and I don’t believe I can accurately describe how good I believe these speakers to be. You have to listen to them with your own ears, which Axiom make possible with their in home trial. That being said, below is an attempt to give you a sense of my experience with them to date.

Firstly, my music background includes playing big band saxophone for a number of years along with live mixing. Faithful reproduction of sound is what I care about and my top three genres include jazz, rock and classical.

I sat down with the Actives, put on Dire Straits’ Money for Nothing and shivers went down my spine as the intro built into the opening guitar riff. The realism of the guitar floored me. It was as if the guitar amp was right in my room. I gave Dave Brubeck’s Take 5 a whirl. The width of the sound stage was immense, the clarity on the percussion so good my wife commented she’d never heard a drum kit sound that good through speakers. She has since stated this a number of times on other recordings. She also has a music background playing the piano and trombone but tends not to comment too much on music being played in the home, so for her to consistently comment on just how good the percussion section is sounding is worth noting. Speaking of sound stage, I put on Mile Davis’ So What and the contrast of Coltrane coming in at 3:27 on tenor at the left to Adderly hitting back on alto on the right is superb. For something a little different I moved to Amber Rubarth’s Full Moon in Paris… Warm rich strings, crisp guitar, silky voice and an incredible sense of understanding exactly how the percussionist's hands are hitting the drums… truly phenomenal!

Axiom knocked this out the park and then some…

Yesterday was a complete listen of "The Wall" with the Yamaha CD-2100 SACD player, and it was AWESOME! The kick drum centers at 35 Hz, and it was hitting me in the chest. The LFR Actives are again making music fun.
