- As displayed by Ken Blecher at InfoComm 2013 in this exclusive video for FRONT of HOUSE magazine's FOH-TV, Powersoft unveiled its M-Force system, a revolutionary drive system for subwoofers that uses fixed coils and moving magnets (rather than the traditional moving voice coil and stationary magnet structure). Intended for high-performance professional sound reinforcement applications, the technology will be offered to other companies as an OEM system and can be used with various types and materials of woofer cones -- a 30-inch is shown and up to 40-inch is supported.
145 db at 30 Hz with polypropylene cone is massive out put and future technology
These things have so much power they can break your fingerbones if you would touch the cone while its driven.
They need to make a home theater version of it. Not as efficient but, can hit so low that you cannot hear it but you can really feel it. Also differences in the motor structure, cone surround, and enclosure design for maximum sound quality.
They did :D Its the Powersoft CineSub
Trust me, you would not want one of those in your house.
They use the 21 inch mforce at the caverns for shows with aka production. They hit 20 hz fairly loud absolutely no distortion
Imagine one of these in a huge tapped horn.... Rat Sound and Funktion One already use them.
Exactly what I was thinking too. I'm very surprised Danley Sound Labs hasn't integrated this yet.
its now being used by function 1 they have it at the red bull clash today
140+ db at 30hz? Holy moly.
it looks like a huge phono catridge nice!!
30" cones with 3" of linear stroke should do 140 easily..
140+dB, sure... but measured where? 1 Meter, or a millimeter?
Pk sound gets 147+dB out of this on their gravity 30s
@@TheTrudell93 147dB, at an unknown frequency, unknown whether it's full space / half space / quarter space / etc, and with unknown THD. And with a crest factor of 10. It is impressive for sure, but Outline's DBS 18-2 for example will also do 147dB half space w/ +10dB crest factor, and it weighs 30 to 60 kg less, and it's about half the size.
Same low frequency extension in a smaller cabinet = less efficient. There's always trade-offs.
How does it sound? Would it sound good enough for Hi-Fi use or is it only suitable for where you want something really loud?
Why the shit would you want to use it for hifi use? Obviously is for PA applications. What a ridiculous comment.
ShedSessions Official People use JBL PA drivers for Hi-Fi... Everyone has their own ways of achieving their perfect sound.
Also, in terms of low frequency extension in a smaller cabinet, the unit effectively has a variable output impedance and you can effectively optimise the t/s parameters for your design goals. Therefore you cant really use traditional design principles to create your enclosure as you'd end up with a box that was too small for the actual driver or way too much port noise. It really is pretty clever.
So no cabinet,I don't know how that works,it's designed for that no cabinet,I wonder if put it in a devastator cabinet
i need 2 of these subs for my bedroom.
I like to know the price!
2500-10000
3 inch excusion... what about THD... 4yr in R&D but no one has mass produccion?
@@peterwing2617 wrong. these dont produce sound, period. so they dont compensate for anything.
145dB @ 8KW = 109 dB 1W/1M.... Seems awfully optimistic! 8KW = 10 Horsepower. Through that little aluminum frame? Seems too good to be true.
Most of the power is heat... We rate speakers by how much input they can take, not how much out put as we would an engine
Wouldn't it be 106 dB 1W/1m or are you factoring some power compression?
Know I’m way late to this conversation but wow what an ad for Cadac.... Just saying
Need it
