Griffin Aperiodic 27 (1980's)
Design by Paul Griffin, made by H.K. Griffin & Co (Electronics), West Bromwich, UK
KEF B200 Bass Unit, 25Hz ~ 2.3KHz
KEF T52 Mid/treble unit, 1.6KHz ~ 7KHz
Coles/S.T.C 4001K hand-picked super tweeters, 6.5KHz ~ 25KHz
Power handling > 70 watts continious, 8 ohms
I purchased two sets of these back in the early 80's from a fancy HiFi store in Redcar, Yorkshire, England. One set has been in storage for over 30 years, the other set has been used from time to time. I recently connected to a modern Marantz amp and really enjoyed the sound in a larger room. What I have noticed recently they sound so much better at slightly elevated sound levels in a larger room and good quality amp.
Their agility and accuracy with Jazz, Classical, and Vocal music is astonishing,

A "unique crossover" makes the impedance of the speaker remain very close to 8 ohm at all frequencies, while the bass unit resonance is acoustically removed by a "twin angled port system".
Not your usual "aperiodic" arrangement of a resistive vent then.
The speaker is new to me, so thanks for sharing.

A new one for me, i do have some info on the Griffin 95. Sitting on 16 B200s, the loading is very much of interest.

Thanks, Dave. There's a nice photo of the Griffin Aperiodic 27 in that link.
The outlets of the two bass resonance removing angled ports are at the top of the enclosure.
Out of interest, I've found details of the Griffin 'Studio Electronic' 85 speaker & the Griffin Pheonix: https://jasperpye.wordpress.com/tag/griffin-loudspeakers/
