LFR1100HP Active Omnidirectional Speakers
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.
DSP, 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.
“I have had the pleasure of owning the LFR1100 Actives for two months and still have that ‘kid in a candy store’ feeling whenever I sit down and listen to them.”
-- David, AZ
“I’ve listened to a whole lot of speakers, but THESE!!! they nail it.”
-- Hans, Spain
“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.”
-- Philip, CA
“It really is nearly impossible to go back to traditional speakers after listening to the LFR1100 Actives.”
-- Tex, AB
“Put simply, the LFR1100 Actives are the best music makers I have ever heard.”
-- Craig, PA
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.
