Klein & Hummel 0300 Mastering Monitors | Old Cottage Audio

Skip to contentKlein & Hummel 0300 mastering monitors

Klein & Hummel (K&H) 0300s have become a staple in serious mixing and mastering studios the world over. These three-way active near/mid-field monitors cover the full audible frequency spectrum, providing an impressively flat response between 30Hz and 20kHz.

 

One of the standout features is their closed cabinet design. Many speakers use ports – holes in the speaker cabinet – to manufacture additional low-end from cabinet vibrations alongside what the woofers can produce on their own. The problem is that cabinet vibrations occur slightly after the woofer output, causing a small delay in the low end that can be deceptive. By avoiding ports, the K&H 0300s avoid this issue, making them exceptionally trustworthy for judging both low end and transients (the attack portion of the notes.)

What do K&H 0300s sound like?

K&H 0300s sound full, rich, and detailed. The bass extension is especially impressive for speakers of this size. And the 3-way design means that mid-range and highs are reproduced with extraordinary detail, saved from having to throw out lows from the same cones.

The sound of the K&H 0300s is roughly equivalent to the sound of high-end Sennheiser headphones. Incredibly revealing, technically neutral, but still a pleasant pair of speakers to listen to.

Why are K&H 0300s useful?

K&H 0300s are primarily used for mastering. Their accurate, full-range response makes them perfectly suited to tackling the broad-brush aspects of mix finalisation. They are especially useful for monitoring at lower levels, able to maintain energy even at quiet volumes – essential for protecting ears, and for dealing with detail at normal listening levels.

While I do use them to check the finer details of my mixes, I tend to reserve them for mastering, mixing primarily on the smaller Neumann KH120s and Avantone Mixcube before moving up to the K&H 0300s for an invaluable change of perspective for mastering.

History of the K&H 0300s

Klein & Hummel was a relatively small German audio manufacturer that achieved a stellar reputation over its 60 years, predominantly for studio monitors, but also for a handful of other rare products like the quirky UE-100 mastering EQ (now immortalised as the Lindell TE-100 plugin).

The company was bought by Sennheiser in 2005, which later folded K&H into Neumann (also owned by Sennheiser). As such, the current generation of these speakers is the Neumann KH 0310.

Interesting features of the K&H 0300s at Old Cottage Audio

The pair of K&H 0300s I have at Old Cottage Audio is pre-Neumann. They are almost exactly the same as the newer generation, though the woofer has been changed slightly for the Neumann model.

Having had these speakers for over a decade, they form the absolute benchmark for me – I don’t really know what something sounds like until I hear it on these.

Number of Vendors seeking consent: Use limited data to select advertising 2 2Advertising presented to you on this service can be based on limited data, such as the website or app you are using, your non-precise location, your device type or which content you are (or have been) interacting with (for example, to limit the number of times an ad is presented to you). Illustrations

• A car manufacturer wants to promote its electric vehicles to environmentally conscious users living in the city after office hours. The advertising is presented on a page with related content (such as an article on climate change actions) after 6:30 p.m. to users whose non-precise location suggests that they are in an urban zone.
• A large producer of watercolour paints wants to carry out an online advertising campaign for its latest watercolour range, diversifying its audience to reach as many amateur and professional artists as possible and avoiding showing the ad next to mismatched content (for instance, articles about how to paint your house). The number of times that the ad has been presented to you is detected and limited, to avoid presenting it too often.

Number of Vendors seeking consent or relying on legitimate interest: Create profiles for personalised advertising 3Information about your activity on this service (such as forms you submit, content you look at) can be stored and combined with other information about you (for example, information from your previous activity on this service and other websites or apps) or similar users.

• If you read several articles about the best bike accessories to buy, this information could be used to create a profile about your interest in bike accessories. Such a profile may be used or improved later on, on the same or a different website or app to present you with advertising for a particular bike accessory brand. If you also look at a configurator for a vehicle on a luxury car manufacturer website, this information could be combined with your interest in bikes to refine your profile and make an assumption that you are interested in luxury cycling gear.
• An apparel company wishes to promote its new line of high-end baby clothes. It gets in touch with an agency that has a network of clients with high income customers (such as high-end supermarkets) and asks the agency to create profiles of young parents or couples who can be assumed to be wealthy and to have a new child, so that these can later be used to present advertising within partner apps based on those profiles.

For instance, whether you saw an ad, whether you clicked on it, whether it led you to buy a product or visit a website, etc. This is very helpful to understand the relevance of advertising campaigns. Illustrations

• You have clicked on an advertisement about a “black Friday” discount by an online shop on the website of a publisher and purchased a product. Your click will be linked to this purchase. Your interaction and that of other users will be measured to know how many clicks on the ad led to a purchase.
• You are one of very few to have clicked on an advertisement about an “international appreciation day” discount by an online gift shop within the app of a publisher. The publisher wants to have reports to understand how often a specific ad placement within the app, and notably the “international appreciation day” ad, has been viewed or clicked by you and other users, in order to help the publisher and its partners (such as agencies) optimise ad placements.

Number of Vendors seeking consent or relying on legitimate interest: Measure content performance 8 8Information regarding which content is presented to you and how you interact with it can be used to determine whether the (non-advertising) content e.g. reached its intended audience and matched your interests.

This will be measured to know whether to produce more posts on hiking in the future and where to place them on the home screen of the mobile app.
• You were presented a video on fashion trends, but you and several other users stopped watching after 30 seconds. This information is then used to evaluate the right length of future videos on fashion trends.

Number of Vendors seeking consent or relying on legitimate interest: Understand audiences through statistics or combinations of data from different sources 9 9Reports can be generated based on the combination of data sets (like user profiles, statistics, market research, analytics data) regarding your interactions and those of other users with advertising or (non-advertising) content to identify common characteristics (for instance, to determine which target audiences are more receptive to an ad campaign or to certain contents). Illustrations

• The owner of an online bookstore wants commercial reporting showing the proportion of visitors who consulted and left its site without buying, or consulted and bought the last celebrity autobiography of the month, as well as the average age and the male/female distribution of each category. Data relating to your navigation on its site and to your personal characteristics is then used and combined with other such data to produce these statistics.
• An advertiser wants to better understand the type of audience interacting with its adverts. It calls upon a research institute to compare the characteristics of users who interacted with the ad with typical attributes of users of similar platforms, across different devices. This comparison reveals to the advertiser that its ad audience is mainly accessing the adverts through mobile devices and is likely in the 45-60 age range.
