And Magnapan 30.7s deliver deep and quite powerful bass.
I've never heard any Maggie deliver bass, let alone deep and powerful bass.
When Magnepan brought 30.7's to dealers on a tour of the country a few years ago, they were absolutely
horrible though they were literally the only pair that existed at the time. The sound quality was just weird…
There were all sorts of phase effects and other things going wrong that just made them not sound good. The designer was literally tweaking the crossover on the floor behind them using wires with alligator clips on both ends!
I had to go listen to a pair of Sonus Faber Amati Anniversario the dealer had it in another room just to cleanse my sonic pallet of the absolute terrible experience.
I hope they've improved since then, but I've never heard bass of note even from a 20.7.
Every Maggie I've ever heard except for a pair of the huge Tympani IVs from the late 1970s has sounded as if they were being run through the high pass side of a crossover that was directing the bass to a subwoofer except no such subwoofer was present in the room.
My local dealer has never again brought a pair of 30.7s in so I can only state what I heard from the prototypes they took on tour.
They've never even brought a pair of 30.7s to RMAF; maybe this year.
The Alsyvox are pricy, but are in the ballpark for what other speakers of that design cost today, including Graz's Apogee Diva Advance 9s.
