Build Quality

KEF Q350

The KEF Q350 has one of the largest speaker cabinet sizes under the KEF’s Q Series. You can already tell that the speaker is durable and does easily topple even with strong vibrations in just one look.

Build Specifications of the KEF Q350:

KEF Q350Specifications
Dimensions35.8 x 21 x 30.6 cm (14.09 x 8.26 x 12.04”)
Dimensions (w/ Rubber feet)36.2 x 21 x 30.6 cm (14.25 x 8.26 x 12.04”)
Weight7.6 kg (16.8 lb)
Cabinet MaterialMedium Density Fiberboard
DesignTwo-way bass reflex

The speaker cabinet is made of medium-density fiberboard, an industry standard, and coated with vinyl. The speaker’s design can reduce the load on the cone, resulting in a cleaner bass.

The speaker now has a larger roll surround than older versions and a newly modified driver, giving it a better bass response even at high volumes. The speaker also comes with an improved Auxiliary Bass Radiator to enhance its overall bass quality and a new cone structure that improves its midrange clarity.

The damped tweeter loading tube in the speaker gently terminates the sound produced at the back of the tweeter, resulting in a better lower treble response. The overall design of the placement of the drivers is near-perfect, as it dramatically improves the dispersion of the sound without any problems.

The aesthetics of the speaker is refreshing, as you can see the integration of the tweeter and woofer into one driver only. The speaker comes with a removable grille, so you can choose whether you cover your speakers or not. Either way, both setup still looks impressive.

The speaker is available in three finishes: walnut, white or black. All finishes give a simple but elegant look to it. It is not that heavy, but it also comes with rubber feet, so it can help its stability when you place it on a table.

Overall, the KEF Q350 is an excellent option if you are looking for a durable bookshelf speaker with a beautiful yet simple design. The technologies used in the driver give it more protection to last longer, and the materials used in its external features are trustworthy to last for a long time.


Klipsch RP 600M

As I’m sure most of you already know, Klipsch is an excellent brand known for its build quality, and the Klipsch RP 600M is no different. It’s one of the largest and heaviest bookshelf speakers of all of the company’s products. It has a typically separated tweeter and woofer placement but still looks beautiful, as the baffle and the horn almost have the same size, giving it an almost symmetrical look.

Build Specifications of the Klipsch RP 600M:

Klipsch RP 600MSpecifications
Dimensions39.9 x 20.2 x 30.1 cm (15.69 x 7.95 x 11.85”)
Weight7.3 kg (16 lb)
Cabinet MaterialMedium Density Fiberboard
DesignBass Reflex via rear-firing port

An industry-standard, medium density fiberboard was used to make the speaker’s cabinet, which is coated with vinyl. The speaker is available in three finishes: ebony, walnut, or piano gloss. The ebony and walnut finishes are scratch-resistant, while the piano gloss gives a mirror-like finish.

Its Titanium tweeter and vented design minimize the distortion of the sound, resulting in a better and cleaner high-frequency performance. Its spun copper cerametallic woofer, a signature of the Reference Premiere Series, reduces the distortion, resulting in better speaker efficiency and performance.

The speaker also comes with Tractrix ports, which allow the air to transfer quickly and efficiently from the cabinet, resulting in a punchier bass and reduced noise.

The speaker comes with a removable magnetic grille, so you have the option to use these to protect the drivers or let them be exposed.

Overall, the Klipsch RP 600M is an exceptionally built speaker. The materials used in the woofer and tweeter are excellent, and you can trust that they will not easily get damaged even if you play them in a high-volume setting. The cabinet is also durable, so you can expect this speaker to last for a long time.


KEF Q350

The KEF Q350 has limited control options because it is a passive speaker. It only comes with a pair of binding post speaker terminals so that you can connect the speaker to a power amplifier. The terminals are durable, so there will be no issues with unstable and loose connections.

The speaker also has a built-in passive crossover with a crossover frequency of 2.5 kHz, which is perfect for protecting the speakers from blowing off.

Overall, the KEF Q350 is still a great bookshelf speaker, despite its limited control options.


Klipsch RP 600M

The Klipsch RP 600M has the same control options as the KEF Q350, although they differ in the crossover frequency of their built-in passive crossovers. The speaker has a 1.5 kHz crossover frequency, which means a lower crossover frequency than the Q350.

Overall, the speaker is still a great bookshelf speaker, as there is not much to expect regarding the control options for a passive speaker.


KEF Q350

The KEF Q350 is a bit expensive as its price is already close to a mid-level bookshelf speaker, but the price you are paying for the sound and build quality is already an excellent deal.

Overall, omnidirectional speakers are not cheap, so paying for this speaker at a near mid-level price point is already a steal.


Klipsch RP 600M

The Klipsch RP 600M is an excellent speaker for an entry-level product. The sound and build quality of the speaker is outstanding for its price point.
