If you need a modular, scalable PA system designed for really large spaces, then the new HK Linear 9 deserves a close look. Offering onboard amplification, DSP processing and network control, these might be the most impressive PA speakers we’ve seen released so far this year.
You might not have come across the HK Audio brand before, so let’s fill in the back-story. HK is a successful German audio brand founded in 1979, originally as an OEM manufacturer. Today the company still manufactures its speakers inhouse in Germany, which is nice to see in this era of “badge engineering”.
HK Linear 9
If you glance through the specs of the new, flagship, active Linear 9 series, you’ll quickly realise that these are serious PA speakers! Importantly, the Linear 9 series is a high-power “long-throw” loudspeaker rage. If you’re looking for a PA system to fill a large venue or outdoor space, then this could be the ticket.
You have a choice of five complimentary enclosures, all of which are traditional, point source enclosures:
- 110 XA – 10″ mid/woofer, 700W RMS
- 112 XA – 12″ mid/woofer, 700W RMS
- 210 LTS – 2×10″ mid/woofer, multi-cell transformer HF, 1000W RMS
- 118 SUB A – 1×18″ subwoofer, 1100W RMS
- 118 SUB BA – 1×18″ band-pass subwoofer, 110W RMS
I was very impressed reading through the specifications of the Linear 9 series. Undoubtedly HK has poured some serious design knowledge into this range. For example, each enclosure in the HK Linear 9 series has on-board DSP processing to complement the integrated class D power amplification.
The on-board DSP gives access to functions such as a: 10 band EQ, variable filters (high pass, low pass) polarity, overall level, limiter, and mute. Furthermore, you can network Linear 9 speakers and access all functions remotely using HK’s DSP Control software.
I also like the ability to rotate the 210 LTS’ multicell transformer, by 90 degrees. This allows you to install the 210 LTS vertically or horizontally as required.
Applications and Highlights
But the two standout designs in this range are the 210 LTS high/mid cabinet and the 118 SUB BA. The 210 LTS promises pristine audio and great directivity, even at high SPLs.
The 118 SUB BA offers a cardioid response thanks to its bandpass design. If you’ve ever suffered from noise complaints due to bass spill, then the prospect of a directional subwoofer is very appealing indeed!
With a starting price of €1499, this is a professional system with a professional price tag. I expect the Linear 9 to be popular with hire companies, touring and theatre shows as well as club installs.
