BTW nu vi snakker historie:
Bjørn Børjas (SEAS) erindring om Dynacohøjtalerne
Dynaco: When Børja came to SEAS, Dynaco was a very important customer. The firm was founded and was owned by David Hafler, producing Hi-Fi and Stereo Electronics, both kits and finished goods. The Dynaco products were very popular and were very often combined with speakers from Acoustic Research (AR), which was a specialized speaker manufacturer. At one point AR launched an amplifier, and thus broke an unwritten agreement between these two firms. Hafler responded by collaborating with SEAS on the development of a speaker which in the spirit of the company should be of high quality, at an affordable price. Hafler and Lian quickly arrived at a construction based on 25TV-EW and H087 in a 25 liter cabinet equipped with an acoustic valve which gave controlled bass and favorable impedance. The crossover was an RC network in front of the H087 tweeter, while the 25TV-EW had a built-in roll-off because of the heavy and high inductance 4-layer coil. Some extra resistors and a switch constituted a 5-position attenuator for treble regulation. The cabinet was solid and well dampened inside with stone wool. On the outside it was covered with real walnut veneer. The front grille was a frame covered with a light linen fabric (not unlike what AR used on their products). Børja seem to remember that a speaker would cost 80 USD over the counter. It was not long before the sale was well underway. And when the product received the tag "Best Buy" in Consumers Report, demand became enormous. Rumors said that the management of AR regretted that they had launched an amplifier, which ironically was practically a flop.

Her er så den forstærker, som muligvis bærer skylden for at der blev taget initiativ til udvikling og produktion af Scandynaco A25.

David Hafler havde tilsyneladende et ønske om at producere en højtaler der umærkeligt kunne glide ind og erstatte AR, det er i hvert fald en mulig forklaring på hvorfor Dynacohøjtalerne kom til at ligne AR's højtalere.
