But please do read about what this classic topology can achive, while we wait for the successor for the F2 - a completely new loudspeaker with capacity and definition and controlled sound radiation.

A 12" woofer and horn on top - the classic style loudspeaker.

Effortless dynamics, large 3-D soundstage, powerful and realistic midbass and lower midrange.

The F2 also adds refinement and accuracy and definition to all this dynamics and headroom.

Updated technology brings out more of the potential and eliminate challenges that characterises this type of topology.

The sound

The F2 is different. The sound has a sharp and revealing character, almost like you can reach out and feel the texture of the instruments.

Overall tonal balance will in most rooms tend to be perceived as rather dark.

The soundstage is 3-dimensional with full depth, and instruments appear like objects with physical size.

LF section

Since the low bass is meant to be reproduced by a separate bass-system, there is no need to push low end extension. Then the speaker can be designed to perform even better in the frequency range from midbass and upwards.

LF driver with high thermal and displacement capacity makes it possible to satisfy sound pressure requirements using a 12" driver. A 12" driver is just perfect to match the AMT horn, it is still in the linear region up to the crossover frequency, and the radiation pattern is just right.

The parameters of the driver is selected for best midrange performance. High BL and modest moving mass gives excellent transient response, at the cost of low frequency extension. Initially this gives a system that rolls of from around 200Hz - too high, we want something that has reasonably flat response down to well below 100hz.

A special kind of enclosure with horn loading and internal damping brings low frequency extension down to 60Hz before it drops off. This is not a real horn, the acoustic port functions more like a bass reflex loading. The internal damping is critical to achieve a smooth response free of any resonances.

The result is a very dry and defined bass, with nice attack.

HF section

The large AMT driver is mounted in a conical horn. This horn controls the radiation pattern and improves headroom at lower midrange frequencies.

A diffusor in front of the AMT, together with carefully tuned acoustic absorption inside the horn, gives smooth and flat response and tunes the radiation pattern.

Crossover network

To make this work as a coherent sound source and eliminate any negative contribution from the drivers outside of their pass-band, a crossover with very high slope and controlled phase was developed.

Order and information request form

Order discontinued F2 loudspeakers

This is not a committing order. You will be required to confirm the order later, after receiving confirmation with all items and prices listed, including shipping cost and expected time schedule for delivery.

You can use this form to initiate a conversation about your desires, no obligations.

Process of ordering

You can contact us by using the order-form above, by mail, on the facebook page, on phone.

When you have decided your final configuration for the purchase, you will get an estimate for expected schedule of delivery. When the order is ready to be sent, you will get a notice, with payment information. Once the order is paid, it will be shipped to you.

As a customer you can make use of our expert knowledge on sound systems. We can predict how an installation will perform in your room. We can support you and guide you through all steps from finding requirements for your system, selection of installation including subwoofers, and finally setting up and calibrate your system to optimal performance.

This process often starts with some simple sketches of your room, perhaps you have a picture, we may look into how you prefer your sound and music. If you have acoustic measurements of your room, those can provide useful information.

You have a dream, a vision, of how the sound will be in your room. We will help you fulfill that dream, by making sure you select the best suitable equipment and are able to install and calibrate the system properly.

Delivery schedule

The F2 loudspeakers are built to order. This means there will be a delay from receiving your order until the units are shipped.

We may have completed units ready for shipping, but this will usually not be the case.


Prices listed here are NOK currency export price excluding taxes. For price in your country look up currency exchange ratios and find any additional taxes - such as VAT/MwSt/Sales tax, which you will be required to pay when the goods arrive in your country.

Norwegian customers should look up prices on the Norwegian language page.

Shipping is not included in these prices, and will be determined individually for each order.

Right to cancel the purchase

You are entitled to receive a full refund of the purchase price excluding shipping cost, upon returning the purchased goods in the same condition as it was delivered, within 14 days after the purchase, if the purchased items are not performing according to your expectations.


Warranty against failure due to manufacture defects are valid for up to 5 years on all components. Normal wear due to use is not covered by this warranty. The warranty does not cover failure due to improper use or any sort of usage not recommended for the specific item.

Disposal of retired electronics and electrical items

Old audio equipment - loudspeakers, amplifiers - that is no longer to be used must be disposed off in a way that ensures no risk for environmental harm. Some countries have dedicated disposal arrangements for electronics and electrical equipment, contact appropriate authorities in your country to receive information about arrangements and regulations.
