A great find came my way in this pair of Noresco NE 561 speakers, these are Canadian made with a well revered Isophon PH2132E dual concentric Alnico 8"X12" woofer with a 3" tweeter center mounted.
This pair of speakers has a beautiful walnut veneer cabinet that was a little sun bleached but a few nice coats of Circa 1856 Naturoil brought out the best in the cabinets.
I have swapped to this oil versus Minwax as the Minwax off gasses for 48 hours and this product is all natural.
I opted to upgrade the internal speaker wire to 16 gauge and replace the tired caps with Solen Fast Caps and it has completely opened up these speakers.
It looks t me like Noresco built these speakers to Isophon specs according to the data sheet.
So how do they sound, absolutely amazing on the Single Ended tube amp. They need a little bump up in the bass region but the mid range imaging is incredible. The cone tweeter is nice and smooth without any paper harshness, almost horn like. The dual concentric driver really shines in placement of instruments and musicians, the sound from one origin source is a real joy to listen to, no wonder the Isophon PH2132 drivers are well sought after.
The efficiency is pretty high of at least 95db at one watt, which suits the tube amp perfectly.
I have become a real fan of well designed speakers that use natural roll offs and a single capacitor in the crossover, it means that the drivers were designed to work together and they are not off the shelf drivers.
Speakers that do this the best are EPI 100's, AR 18B's these Isophon drivers, the Tannoy Oxford Gold's and the Sound Dynamic Concert 500's all have a 1st order crossover and they all sound best on a tube amp.
These Noresco'c image incredibly well as if they are a window into the music. If you are a tube aficionado these speakers should be on your list of must hear speakers.

I cannot find actual plans for this cabinet anywhere. The plans posted seem like they are for the the larger speaker in the line? Any tips would help. Thanks. Great site!!!
