- Product Name: Q Series 6.5" 2.5-Way Floorstanding Speaker (Each)
- Color: Satin Black
Audio
- Speaker Type: Floorstanding
- Enclosure Type: Bass reflex
- RMS Power: 150 watts (The maximum amount of continuous power the device is able to handle.)
- Peak Power Handling: 150 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
- Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
- Minimum Frequency Response: 48 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 28 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Sensitivity: 88 decibels
- High Resolution Audio: true (Hear music the way musicians and sound technicians intended it to be heard. Products that support hi-res audio deliver audio signals with a dynamic range and bandwidth far greater than that of a standard CD so you'll be able to enjoy pure music with outstanding sound quality. The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)

Listen to natural cinematic sound with this KEF floor-standing loudspeaker. Its 6.5-inch aluminum low-frequency driver with an enhanced auxiliary bass radiator keeps the low-end details clean and crisp even at high volumes. The Uni-Q driver array of this KEF floor-standing loudspeaker evenly disperses crystal-clear, accurate audio frequencies at 48Hz - 28kHz.

6-1/2" aluminum woofer: Along with 1" aluminum tweeter for a complete range of sounds.
6-1/2" aluminum full-range driver: Delivers high and low tones.
2.5-way speaker system: Sounds like 1 source rather than several separate sources.
Removable black grille: Remains acoustically transparent while protecting the speaker's components. (Sold separately).
Bass reflex enclosure: With a rear-firing port promotes optimal performance.
48Hz - 28kHz frequency response: Ensures a wide range of accurately reproduced sound.
88dB sensitivity: Ensures crisp, robust audio.
8 ohms nominal impedance: Ensures efficient conduction of power through the speaker.

Q: What is the minimum frequency response of the speaker?

A: The minimum frequency response of the speaker is 48 hertz.

Q: What is the speaker's impedance?

A: The impedance is 8 ohms.

Q: It appears that the only ACTUAL speakers are the full range speaker with the tweeter in its center at the top. The other three seem to be just passive radiators that do nothing. I want to know exactly what I'm getting, so let's drop the "driver" BS please

A: 2 are passive radiators. ( no power to them or voice coils) the other is absolutely an actual driver.

Q: frequency range

A: I assume you mean frequency response, since giving merely a frequency range is meaningless. One could claim 1 Hz to 100 kHz without necessarily being wrong. What you really want know is: 48-28,000 Hz (±3 dB). That part in parentheses is important.

Q: How many watts per channel?

A: That's a strange way to ask the question. The recommended power range is 15-150 watts, as plainly stated in the specifications from KEF (download the manual).

Accurate sound reproduction
5.1.4 system using all Kef, 750s front, 350s rear, 250 center, with dolby atmos q50a. Did it this way so my 5 floors all had 6.5 inch drivers and an accurately dispursed sound field. I dont like the sound near the screen but everywhere in the room. This setup does the job. Accuracy is rediculous. 750s are so spatial sounds like the center is on when it's just the 2 speakers in stereo. These are paired with Paradigm v12 difiance sub, but Im sure the kef cube would do just as well. Ideally these work best in a home theater but will not provide the bottom end you need without a sub, with the sub they are spectacular. Runing denon 3600 avr but added marantz 7055 amp for extra power. Listening to streaming music in stereo on these is an absolute pleasure. Kef delivers wonderful accurate sound reproduction with subdued highs, not overpowering like other brands, everything is there, but its not an "in your face" overdone speaker. B ans Os and Klipsch are great but too much blasting highs for me, listen to them all, it's all about personal preference. This is British audiophile sound at its best!! Cons: purchase of metal saucers to protect floors from spikes, but you get much better sound with these elevated off the floor in the stands. Make sure you position these ar least 2 feet from any adjacent walls. Had to buy the grills separately.

Beautiful sound-beautiful design!
This is the second pair of hifi speakers I’ve had. I’ve always been know to my friends and family as the techy and audiophile. Lover of higher end quality products. KEF is not a brand everyone knows about. But those who do understand they hold weight in the audio industry. They hold their value as well. The KEF Uni-Q family of speakers are considered the value end of the spectrum. But they are far from budget. These speakers are high end and hifi if I’ve ever heard. The 4 driver design looks classy yet simplistic. But put out beautiful music/movie sound(use with projector). Sharp and crisp highs. They handle soo much sound that you wish these speakers 4 drivers were all uni-Q drivers. But the one is plenty. 2 speakers are active 2 are passive radiators I believe. Mids or vocals are clear. Not overly done. But balanced and punchy. You can hear every word clearly. The one part I would say that isn’t perfect is the bass. While great isn’t perfect in my opinion. I would say it’s strong but not as low as I like. But I’m running currently as a 2.0 set up. I’m used to an external sub. So that’s why. Still very very happy and border line in love. I love the cabinet in the walnut finish. I didn’t think I would love it as much. Because I’m an old school guy who loves everything black. But it’s real and lovely. Helps with the sound quality as well. These speakers do come with the sound saving bases which are very easy to install. Took me about 10 mins to install and adjust the height and level to my liking. I’m using 14 gauge pure copper oxygen free speaker wire without banana clips. And that’s perfect for me. Crystal clear sound. Music is pleasing soo much that I sit and just listen to music for hours. You do. It need to be right in the center. They disperse sound everywhere .Pushing these speakers with 125 watt per channel amp and that’s plenty tho these are rated for a little more power is need be. Overall these are the best speakers I’ve had thus far. Fair price point for the quality. You will not be disappointed with these KEF floor stand speakers. Amazing sound and beautiful to look at! Note: speaker grills are not included which is a bit disappointing as well. But not a deal breaker. My kids know not to touch daddy’s stuff. Good luck and happy shopping!
