The OA60 is not yet in production but it is not to far away. It has been shown but not played to the public on the “High End 04” exhibition in Stockholm. The Carlsson OA-60 is the top model for the new series in the new millennium.
The Ortho-acoustical principles will be upheld and developed.
The new models are designed according to Stig Carlssons unique OA-principles, this result in a natural music reproduction in normal living rooms where the effects from the recording room is also present. No information is added or removed.
The design work behind the new speakers is done by “SSC – Stiftelsen Stig Carlsson” (The Stig Carlsson Trust) and their sound- and loudspeaker experts.
Designing speakers after the OA-principles is a very time consuming activity. Using traditional design-programs for loudspeaker building is not enough, too many new and different factors affects the sound-reproduction. It takes a deep knowledge about Stig Carlssons methods and theories to be able to develop a speaker that Stig Carlsson would approve. Due to this the waiting has been long. The work with the OA60 is nearly finished now but no time for introduction on the market has been set.
Placing the speakers
The Carlsson OA-60 like all other OA speakers shall be placed against a wall. The room is a part of the design of the speaker where the bass-boost supplied by the wall is included in the design in order to have a correct sound-reproduction.
The design
This speaker is like other Carlsson designs designed from the function of the speaker. This results in a speaker that is higher but with a smaller footprint compared to earlier models. On top there is a hood with two slanting sides. Under the hood you will find the baffle and the two absorbent panels. The horizontal panel is 51cm above the floor as on all the new coming models. There is also an absorbent panel beside the baffle, alongside the back wall. Together these absorbent panels removes most of the early reflections that otherwise would have influenced the sound-reproduction.
No specific details can be revealed at this stage as the finished design is not yet determined.
Principle
The OA-60 is a 36 liters twoway bass-reflex speaker.
Woofer
The information is unsure but probably the woofer will be a totally new 7-inch mid-woofer, designed by SSC specifically for this model.
Tweeter
The tweeter is probably a special luxury version of the new Carlsson T-11oa found in the new model OA-58. The T11-oa is a silk dome tweeter designed by the Carlsson trust with extraordinary low distortion and wide sound dispersion.
