That's true. It also depends whether they're using lab test results or in-room response. JA measured the S5 Mk2's -6db frequency at just under 30Hz, whilst MC measured the -6db at 24Hz (digging down to 22Hz @-6db with room reinforcement).
Ah yes, pure physics!...MC equated the S5 Mk2's twin 10" bass units to a 370mm (14.5") bass driver. And they have massive magnets, long-throw voice coils etc. As I understand it, with WB's isobaric driver configuration the two drivers are wired out of phase with each other, and the iso-group has the same resonance frequency, Qts, distortion, excursion etc as one driver with the same applied signal. Whilst all other aspects are unchanged like resonant frequency and maximum SPL.
Horses for courses. Not everyone will be able to accommodate a sub...for example those whose listening room also doubles as their living/dining room like me. But I agree WB's isobaric bass configuration is very punchy and dynamic...great way to get maximum output with less cabinet volume. This new model should do well for WB at it's price point (€35k, or approx $38kUS based on the current exchange rate + shipping, import taxes etc).
Fascinating stuff. It's good to get an AE's perspective on different design configurations to provide some perspective. Magico's design for the S5 Mk2 could be seen as the 'brute force' approach, with superb driver design & utilizing similarly advanced CAD/Finite Element analysis modeling tools. WB's approach is about more from less & design innovation. The common factor both marques share is superb engineering.
Not confirmed yet. That price was posted in Wizard's blog. Also note that is the European price. The US price will likely be quite a bit higher once shipping, import taxes/duties & the exchange rate are factored in.
You also have to add in a reasonable margin for the distributor, who has to invest substantially in the product line to adequately support it.
