In mint condition. Sonab OA-5 is, without competition, the most widespread speaker in Sweden, ever. In the end of the sixties everybody in Sweden wanted a pair of the strange and wellsounding speakers. The standing matchbox design struck well with the pure design trends and the omnidirectional sound suited the modern man who mingled in couches, floors and on beds.

OA-5 Typ 2 (Mk II) is a development of OA-5 Typ 1 (Mk I). It was equipped with 1 of the cheap but well sounding fullrangespeakers, Philips 9710 and 4 inward facing/omnidirectional conetweeters of the same type that made the Kolboxen (Coalscuttle) and OA6 Typ 1 (Mk I) successful, the Peerless MT20HFC. The filter components were aircored inductors and standard capacitors.

“OA-5 Type 2” differs from its predecessor in one major area: The baffle has been elevated up to level with the topside of the speaker. This leads to sonic advantages: The tweeters can now radiate freely in all directions, the mid-range radiates more freely also. This makes the sound clearer and airier. Furthermore the stereo-image becomes clearer, although the width is not a strong area in any of Stig Carlssons models from the sixties (they were actually mono-designs). The increased boxsize should also allow for a deeper bass-response. For now there is no technical data available for “OA5 Typ I” and therefore it is not possible to say how much deeper it goes. (If you have a manual please scan it and mail it to Carlsson Planet to be published in the future.) The downside of the simplified design without port tube is something that MkII has inherited from its predecessor. This is a cheap solution to save costs in the production. Apart from this the speaker is well designed with good-quality crossover components, braced boxes etc. This results in good soundreproduction for its era. OA5 Typ II (MkII) was on the market from approx. 1970-1973.
