LFR1100 Active Omnidirectional Speakers

LFR1100 Active Omnidirectional Speakers

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. 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.

Axiom's DSP
Axiom's DSPDSP, customized for the LFR1100s

There is one DSP included with each LFR1100 Active (two per pair). It has one input (RCA or XLR) and five outputs (RCA or XLR) which separate the information sent to each of the five driver groups in the speaker. The outputs are designated for each driver group. By doing this we have even more control to tailor each one of the measurements that make up the LFR1100 Active family of amplitude response curves. This heightens the accuracy of the performance you experience. It also gives you the advantage of a higher achievable dynamic range as you now have an amp channel designated to each driver group, eliminating the need for a passive crossover in the speaker.

The DSP included is in a stand-alone case that sits between your preamplifier or receiver and the amplifiers.

"The LFR1100 is absolutely crystalline in its output and the level of detail is just mind blowing. I cannot believe I am saying this, but it is literally like having the artist in the room with you."
-- Dale Rasco, HomeTheaterShack
"I always look for speakers that melt the walls away and transport me to the concert hall; or into the world of the movie I'm watching. The LFR-1100s did this in a way I didn't think was possible; especially for a speaker pair that costs less (way less!) than $25,000."
-- Chris Eberle, Secrets of Home Theater and High Fidelity

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. You will love the dynamic range you will experience.

Questions We Get All the Time

Why a Digital Signal Processor (DSP) for the LFR1100?

In order to get optimal integration between the front and rear drivers each set of drivers needs to have a very unique set of amplitude response curves. This isn't possible to do with a passive network, so we employ the power of a DSP to ensure we end up with the desired family of curves measured all the way around the speaker. This ensures complete control over the midrange fidelity of the omnidirectional speaker, and keeps it from suffering from a lack of image focus or spectral neutrality which is so often a problem with omnidirectional designs. The DSP tailors phase response between the front and back sections, as well as the amplitude response characteristics.

I’ve listened to a whole lot of speakers, but THESE!!! they nail it
- 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…
- David
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.
- Craig
Played the soundtrack from the Accountant for a client. The drums hit so hard he literally jumped out of his seat.

The sound quality of the LFR1100s Actives is incredible. Most excellent work Ian.

Thank you for the music!!!
