    Monolith K-BAS Reference Series Bookshelf Speakers (Each)

    K-BAS Reference Series Bookshelf Speakers

    Enjoy great bass in a bookshelf space! The Monolith K-BĀS Reference Series Bookshelf Speakers utilize K-BĀS (Kinetic Bass Amplification System) technology to give you low bass extension that no other speaker at this size or in this price range can match. Featuring an impressive soundstage, pinpoint detail, and incredible articulation – all with bass you can feel - these speakers are perfect for apartment dwellers, audiophiles, or anyone that loves great sound!


    K-BĀS Reference Series


    K-BĀS: The Kinetic Bass Amplification System utilizes a specially designed cabinet and port technology to produce incredibly powerful bass.

    Style: While Monolith believes in function over form, there is nothing wrong with having speakers that look good, too. The simple yet elegant appearance of the semi-gloss, satin black finish is complemented by the black woofer cone and titanium dome tweeter. A black cloth speaker grill is also included.

    Imaging: Utilizing a 1" titanium dome tweeter and a 5.25 polypropylene _ mica woofer, the Monolith K-BĀS Reference Series speaker places instruments and voices in an amazingly layered and precise soundstage. Spatial focus, depth, width, and accuracy are hallmarks of the design.


    Kinetic Bass Amplification System (K-BĀS)

    K-BĀS is shorthand for Kinetic Bass Amplification System. This loudspeaker technology makes it possible to accurately reproduce low frequency sounds, while utilizing a smaller cabinet and drivers. This passive system is compatible with all amplifiers and receivers.

    K-BAS Reference Series Bookshelf Speakers

    How K-BĀS Works

    A unique cabinet design and a variety of existing speaker port technologies (acoustic suspension, bass reflex, and transmission line) have been combined in a way that simply defies belief! Low frequency sound waves travel through the internal cabinet into a specially designed chamber. This chamber amplifies the driver's backwave, significantly increasing the kinetic bass energy as the air is accelerated out of the vent. The result is that the frequency response is greatly enhanced and dynamic range is dramatically increased.

    K-BAS Reference Series Bookshelf Speakers

    The Monolith K-BĀS reference speakers utilize low loss polyester capacitors in the signal path to ensure a fast rise time. The woofer and tweeter circuits are assembled on separate boards with components arranged to minimize or completely eliminate crosstalk. Chokes are wound using large diameter wire, so these components will not add any coloration to the source. The woofer inductor uses the highest grade core material to eliminate any chance of saturation within the rated power range or hysteresis, which would color the input material.

    The price point of this bookshelf speaker, Monolith K-BAS Reference Series Bookshelf Speaker, is the same as Elac Uni-Fi B5. How its sound quality compare to the highly rated speaker?
    Vernon V on Nov 22, 2016
    BEST ANSWER: I have both and I can tell you Monolith has wayyyyyyy more bass than ELACs. Speaking of bass they're in a completely different league.
    Can the tweeter be rotated 90 degrees for use with the speaker sitting on its side?
    William F on May 30, 2017
    BEST ANSWER: The tweeter cannot be rotated.
    Why are there no reviews for this product? I am eager to learn more about how they perform.
    Robb W on Jan 26, 2017
    BEST ANSWER: This is a fairly new product. We are waiting for them as well. Thanks for the question though.
    Can Schiit Jotunheim power these speakers efficiently?
    A shopper on Apr 9, 2017
    BEST ANSWER: The Jotunheim is for headphones but its outputs CAN be hooked to a separate speaker amplifier to power these K-BAS
    Do these have a wall mount keyhole?
    Vergel O on Dec 1, 2016
    BEST ANSWER: No, they do not.
    is the inside of the square port in the face tapered to the back or just open to a larger inner chamber on the reverse side?

    Best for less
    Outstanding bass response is great for classical
    music lovers; the basses and cellos really shine.
    It's tough even to sit in a concert hall and get the
    energy here. The bargain priced Pioneers sound
    thin in this area, the 59-100 hz range. Also, since
    tweeter is nearer the enclosure bottom, it's
    closer to ear level with speakers set on a desk.
    Works well with Polk slim center channel.
    Thank you for this outstanding budget value,
    less than a third the price of the Solus Entre
    (see 8/17 Sound & Vision review.)

    bargain stereo speakers with high-end sound
    I honestly did not quite expect the total musicality that these well-designed speakers presented. they provide honest bass down to about 30 cycles, and at reasonably room-filling volume. their wide uniform treble dispersion creates a broad, airy stereo image with a very wide sweet spot [really a sweet area] wide enough for at least 2 people to enjoy the same stereophonic image placement. unlike most high-end speakers that require perfectly recorded "audiophile approved" recordings to sound good, these enable me to unreservedly enjoy the sound of my collection of old recordings, most of which were not well made or were worn. these speakers make ALL music sound good! highly recommended. :)
