After a two-year development period we proudly present the new subwoofers in the 1723 Series. Improving what were already market leading products was not an easy task to tackle. Our statement series offers an exceptional balance between perfect music reproduction as well as sheer bass depth and output. A premium driver needs premium amplification. Actually, our new Avalanche 800 IQ & 1200 IQ amplifiers are the market statement of high-power amplifiers with a new mindset of features and usability.
STORY OF ARENDAL I was born and raised in Arendal 1978, Norway. As a kid I enjoyed many activities, such as catching fish for my cat Johnas, riding my bike, playing football and video games, and hanging out with friends. Of course not a day went by without wrestling with my older brother Dan Benny. My dad, Jan, founded an electronic store in the 70´s and it quickly became the top selling store of it’s kind throughout Norway.
and yet aesthetically beautiful, surrounded by a unique story - ours. Arendal Sound builds upon traditional and historic Norwegian elements, where solid craftsmanship and finish quality are a top priority, backed with pleasure in the use and pride in the ownership. We even want to show our beautiful country to our overseas customers and invite them to Norway.

PREMIUM BUILD QUALITY Rock solid HDF cabinets Higher density and naturally better damped than MDF (Medium Density Fiberboard), using HDF (High Density Fiberboard) results in a sonically inert cabinet. HDF was also chosen because it can be machined much more precisely than MDF, which is especially important for precision critical areas like the two part HDF & Aluminum waveguide.
Premium Finishes No plastic - “Green sound” All Arendal Sound 1723 speakers and subwoofers comes in four premium finishes; Well, you may find a cable strap somewhere in plastic, but all components in Arendal Sound which affects the sound are built up from non-plastic parts. High grade aluminium back plates on subwoofers and speakers. Even our logo is in anodized aluminium.
AVALANCHE 800 / 1200 IQ AMPLIFIER Intelligent Powerhouse We introduced the 550 IQ which already has set marketleading standards. The Avalanche 800 IQ & 1200 IQ build on the 550, but have been optimised, equipped with additional features and highly refined for our hi-end 1723 subwoofers. Impeccable performance, conservatively rated at 800/1200W, with capabilities that make the difference. Subwoofers are not the same anymore.

13.8” WOOFER Redesigned masterpiece We knew we could achieve more by investing all our focus and know-how to go beyond what’s already in the market. It’s still 13.8”. Looks about the same. But, it’s a different beast. The best we have ever made. With 50% higher excursion, better performance and increased dynamics. The new 13.
Lack of compression = extreme dynamics The airflow venting below the dust cap (venting holes in the cone body) and the spider (venting holes in the frame) have been added for two very important reasons: 1. We have improved the Airflow venting compared to the previous version by adding more vents in the bobbin body to further increase the air flow under the spider for better heat dissipation and to reduce airrush noises even further, resulting in less distortion.
PLACEMENT & SETUP Subwoofer placement can make or break system performance. As the foundation of rhythm, timing and impact upon which music or movie soundtracks are built, a poorly positioned subwoofer will deliver uneven, tuneless, slow and soggy bass. The whole system will not sound good. End of. The performance of a subwoofer is inextricably linked to the room in which it sits It is therefore impossible to optimize the subwoofer without considering the room and it’s contribution.
You will still get the first reflection from the opposing walls, but that’s half the number of first reflections and the resulting peak/dip structure in the room might be slightly increased, but it will be simpler and more likely to be similar across a wider number of seating position. This presents a far simpler proposition for the Auto EQ in your AV-Receiver or Processor. But there is more Each first reflection, sits on an indirect path to your ears, that is longer than the direct path from the subwoofer.
reduction in distortion for a given volume setting. Spread the subwoofers further apart, and that advantage halves to closer to 3dB. 3dB is still a useful output, but separation makes a number of factors more difficult to deal with. For one, rooms are rarely acoustically symmetrical.
But That Looks Awful! Nobody said this was an absolute, just the least compromised in acoustic terms. The reality of a harmonious domestic existence may decide otherwise, so side by side is a close second best, with any position that moves the subwoofers apart, progressively worse. We will note that there are many other combinations of multiple subwoofer installations including one in each corner, or the center of each wall.

HOW TO CONNECT How to connect the subwoofer Connecting to a stereo setup Depending on your subwoofer layout, we recommend two different methods of connecting the subwoofer(s) for a normal stereo playback system, where there is no dedicated subwoofer output from the source.
Dual subwoofer connection When using two separate subwoofers in a music system we recommend using L and R outputs to each subwoofer (L goes to left subwoofer, R goes to right subwoofer) instead of summing a mono signal on each subwoofer if they are located on each side of the front speakers. This will ensure a true stereo image throughout the entire frequency spectrum.
Connecting to an A/V-Receiver For a typical AV Receiver/Processor connection, we recommend using a single RCA (fig. 1) or XLR cable between the receiver’s Subwoofer output (SW Out, LFE Out or similar, please refer to your product manual) and connect to the LFE input on the subwoofer amplifier. Where an AVR/Processor has two or more subwoofer outputs, only use one to each subwoofer. There is no advantage in using two outputs into one subwoofer.
Unique combined A/V-Receiver and Stereo system connection The Avalanche 800/1200 IQ amplifier has the ability to utilize two separate systems on the subwoofer inputs. You can use the trigger signal to assign one of the inputs when it has a signal, and when it does not it will automatically connect to the other input when it receives a signal. This means you can have one subwoofer and use it both for your home cinema system as well as your separated stereo system.
AMPLIFIER OPERATIONS AVALANCHE 800IQ/1200IQ Quick panel overview 1. High resolution 2.6” LCD colour display. 2. Adjustment knob - To navigate the menu. 3. Menu & Back button - Enter the menu or back from settings/menu. 4. Enter button - Enter any setting in the menu or entering submenus. 5. 3-12V trigger - Triggers the subwoofer unit on/off. 6. Service input - USB input for uploading firmware. 7. Input 1 & 2 - RCA inputs. 8. Output 1 & 2 - RCA outputs. 9. Input 1 & 2 - XLR inputs. 10.
Amplifier operations When the amplifier has been turned on, and the greeting has been presented, the amplifier is ready to use. To check its status simply press any button or use the adjustment knob to activate the LCD screen. From there you can enter the menu by using the “MENU” button. To store any settings in the menu, press enter. By pressing the Menu/Back button, any adjusted setting will not be saved. Menu When you enter the menu, you will be prompted whether to do settings for RCA or XLR inputs.
Main Menu 1. Levels - Adjusting input gain and output levels of the subwoofer. 2. Crossover - Setting desired Low Pass Frequency, Phase and Signal invert. 3. Parametric EQ - 7 band parametric equalizer for optimizing the subwoofers frequency response to your room. 4. Input / Turn-on Make settings for which input is active under different scenarios. You can even use the subwoofer in two separate systems with automatic triggering between them. 5.
Crossover Menu 1. EQ Mode – EQ1, EQ2 & EQ3 3 modes for sealed subwoofers, 6 modes for vented subwoofers as they can be used in vented or sealed mode. EQ Mode • LPF Frequency • • Crossover Menu LPF Bypass EQ1 - gives a flat ground plane response to under 20 Hz, which will give great emphasis on the deepest bass in-room. For movies this can be especially appealing. We recommend this setting for larger rooms.
2. LPF Bypass - On/Off. If On is selected, then the Low Pass Filter will be disabled. For Home Cinema use, where an AVR is used we recommend LPF Bypass – On. For stereo users you may leave this setting Off, so you can adjust the Low Pass Filter under next step. 3. LPF Frequency - The Low Pass Frequency is adjustable from 30 Hz to 160 Hz in 1 Hz increments.
5. Subsonic Filter - Selectable subsonic filter settings, that will filter away the deepest frequencies. Selectable from 12 Hz to 31 Hz. In off mode the amplifier has an internal subsonic filter at 10 Hz to prevent instabilities in the power supply. Adding the subsonic filter will ensure the subwoofer has less excursion in the deepest bass, and typically when filtering away some of the deepest bass it will sound even “tighter”. 6.
7. Phase - Adjustable from 0-180 degrees. We recommend leaving the phase at 0 degrees when using an AV-Receiver/Processor with time alignment (speaker distance) feature. For music setups the phase needs to be adjusted so the subwoofer blends with the front speakers. Pro tip; Have a friend/wife/mom help adjusting the phase while you sit in your listening position. Play some music with a steady bass beat, and when you hear the most amount of bass, the phase is correctly adjusted. 8.
Parametric EQ 1. Band - 7 selectable EQ bands, to optimize frequency response in your room. 2. Freq. - Adjustable frequency from 12 to 200 Hz, in 1 Hz increments. This enables a pinpointed adjustment of any irregularities in the room response. 3. Q - The Q of a frequency adjustment means how wide or small area surrounding the selected frequency you want to affect.
Input / Turn-on Selectable input turn on process, choose from 4 different Auto-on modes, 4 different 12V trigger modes and 8 different Dual Source modes. The Dual Source turn-on control is created for customers that use the same subwoofer in two systems, one typically being stereo and the other being home cinema. This setting enables one input to be triggered and locked by 12V signal, and when the 12V signal is turned off, the other input will be active for auto-on function.
