HELIX IK S10

Flat design - deep bass
With the HELIX IK S subwoofers, the realization of particularly flat and compact enclosure designs is no longer a problem. The extremely shallow installation depth opens up new installation possibilities without any acoustic compromises. But above all, thanks to the use of large voice coils and the low resonance frequency, the HELIX IK S series delivers an absolutely superior bass performance that is in no way inferior to larger woofers.

Attention to detail and clearly thought-out
The extremely torsion-resistant sandwich paper cone in combination with our heavy-duty drive system converts amplifier power into powerful sound pressure in no time at all without compression effects, but also demonstrates sensitivity with subtle beats.
A special highlight: the magnet system has a threaded hole on the back, allowing the woofer to be screwed to the rear panel of the cabinet. As every millimeter of construction depth counts with flat designs, this effectively reduces cabinet vibrations even with thin walls.

"All inclusive" for self-made enthusiasts
In addition to the high-quality cabinet connection terminal with gold-plated screw connections, a solid protective grille and a cover ring are also included in the scope of delivery. For optimum bass performance in DIY installations, our technical data sheet includes recommendations for closed and bass reflex enclosures with all parameters such as net volume, tunnel tuning frequency or DSP settings.

Wiring wizard

Use our wiring wizard for simple wiring of speakers and subwoofers or to find the optimal setup for your cabinet! The right connection is important for your amplifier! Low impedance operation can damage the amplifier!

✓ Series connection: The impedance increases in number

✓ Parallel connection: The impedance decreases in the number

The data sheet shows you which connection the respective amplifier is designed for!

Port calculator

Our port calculator shows you which tuning your housing has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

The net volume design for your woofer size in music mode can look like this

Bass reflex:

✓ 6.5" (16.5cm) = 10 - 15 liters

✓ 8" (20cm) = 20 - 30 liters

✓ 10" (25cm) = 40 - 50 liters

✓ 12" (30cm) = 60 - 80 liters

✓ 15" (38cm) = 100 - 125 liters

✓ 18" (46cm) = 180 - 240 liters

✓ 21" (54cm) = 230 - 290 liters

Products

We use several indicators for sufficient transparency in the store. All products are marked several times with the corresponding availability and delivery time. The availability indicator shows a rough overview of the stock quantity; if there is excess stock, the indicator is automatically hidden.

Items that are not available cannot be ordered.
To avoid unnecessary waiting times, we have set up an e-mail notification function for you. As soon as the goods arrive, you will automatically receive a notification of availability after entering your e-mail.

Manufacturers who provide data sheets or operating instructions can be found at the end of the item description for download.

Unfortunately, it is difficult to give a general answer, as all woofers and speakers are constructed differently and have different coils, plus the amplifier, which must be designed for the connection impedance. You can simply use our wiring assistant, enter the number of speakers, resistance and wiring variant and have it calculated. If the amplifier can handle the connection impedance, nothing stands in the way of the wiring.

Amplifiers which have a release up to e.g. 1 Ohm can also be connected with 2,3,4 and higher impedance.

✓ 21" (54cm) = 230 - 290 liters

If you prefer to listen to charts, rock, pop or e.g. techno, the tuning should be a little higher and is usually in the range of 40Hz and higher. The range of RnB or Ami HipHop usually plays in the 30 to 40Hz range.

In short, clipping is an "unclean signal". You can usually recognize clipping in woofers when there is an electrical smell, the woofer stinks and becomes hot. With loudspeakers, it can also be noticeable through unclean reproduction. The fun is over when the coil has unwound from the carrier. Many amplifiers now have a clipping LED integrated in the output stage or in the bass control; if the LED lights up, you should definitely turn down the volume. If the amplifier does not have an LED, the only way to position the gain correctly is to use an oscilloscope or other aids. However, this requires a certain amount of basic knowledge in order to set the amplifier correctly.

We almost exclusively offer products and manufacturers that we use ourselves and install regularly, true to the motto "quality not quantity", so we can usually tell you what to expect. All products are sensibly designed and selected to cover a wide range, for reasonable sound optimization and, above all, to achieve the desired goal. If you have any questions about your setup or plans, please contact us!
