"You will have a hard time buying more musical naturalness at any price... (the A-25s) are quite probably the best buy in high fidelity today."
So said J. Gordon Holt, founder of Stereophile Magazine, about the legendary Dynaco A25 launched in 1969. That's no longer made, and this SEAS A26 is the A25 "re-invented" with modern drivers.
Strength of the A26 lies in its simplicity. A single 10" A26RE4 with a classic paper cone is driven full-range. It can be because it has an incredibly smooth roll-off down into the midrange. So this is completely unfiltered for a pure delivery.
Crown jewel is the T35C002 1,5" dome midrange/tweeter that is matched with the woofer's roll-off. The simplicity is here as well: a single capacitor (Mundorf MCap SUPREME) with one resistor (Jantzen Audio Superes), that's the idea. A single-order filter.
Having the built the filter, I've applied a few tweaks that I learned on these forums right here. First the Vishay Roederstein MKP1837 bypass condensator for an improved transient response. Second a Jantzen coil (not on photo here) to even out the response curve some more. This did turn it into a second-order network though without sacrificing much in the way of phase.
All in all a beautiful set that comes alive paired with a good (power) amp (I had it on a Hypex UcD).
I've built the set with much love. Now I'm offering them because I'll be focusing more on home theater in the living room, whilst real music listening will move towards headphone sessions.
A unique, home-built set for someone with the right passion. I built this for around € 1.000 (1,200 US$) and I'll consider fitting offers.
Of course they're available for listening though COVID-19 restrictions might hamper your way getting to Nieuwe Niedorp, The Netherlands.
As for color, I painted them white. At the moment they're covered with black grills as a precaution against toddler hands going where they shouldn't. Surely enough the grills can be removed and if you want, I will remove any glue remains, sand and repaint it. No problem.

Here's to hoping it'll find a new home with someone's that's been passionate about this set as I.
