Based off the Magico's I've heard in the past, if I won the lottery these would be at the top of my wish list.

I can't even imagine 136 dB at 20 Hz. Is that a total pie in the sky piece of manufacturer press or has anyone ever been in a room that got close to that?

I call BS on the numbers as well. Is this sealed or ported? It looks to be dual opposed sealed and two LMS5400's which have similar x-max, as well as the UXL-18, can't do those numbers, even in room. This better be a dual driver tapped horn tuned to 20hz to reach those numbers. I mean dual GH's would reach 128 dBs at 20hz outside so they can do it indoors, but not at 1% THD!

I've experienced 137 db's in a room with dual Orbit Shifters but no way it was at 20hz.

And just for reference and for those of you playing the home game, TWO TCSounds LMS-Ultra drivers together can produce a maximum of 118dB @ 20hz at 1 meter in an acoustic suspension alignment. Room gains will boost this number of course.

Luke, if anyone can hit that number of db's at 20hz it's you.

What 'real world' commercial (non-DIY) sub would get closest?

Funk 18.0? Danley DTS 10?

Good find!biggrin.gif

It's back!! Wine of the Week! Clos Martinet Tinto, Priorat DOCa, Spain ~$60. If you've not had a good Priorat, you've not truly tried Spain's smallest, yet most unique terroir.

Scanning through here

http://www.data-bass.com/systems

Shows that only PB13, a Chase sub and two Danleys were above 110 dB (excluding DIY). No JTRs or Seatons measured here though.

I 90% want to say the claim is BS, but Magico really does make cost no object speakers...so it would be interesting if it actually ended up being real, or at least close!

I don't see why 136dB can't be achieved. It doesn't state the conditions. Let's consider the following

Let's assume the Magico is a ported sub.

A single ported PB13 can do 110dB with an above average quality 13.5'' driver.

Considering a top quality 13.5'' driver like the JL has 3-5dB more output than the Ultra 13 (when comparing sealed vs sealed), a top quality 18'' driver should be able to produce at least 6dB more, so 116dB.

Adding a second driver will increase output by 6dB, so 122dB

Converting from 2 meter GP to 1 meter GP adds 6dB, so 128dB

Measuring it in room, you can add at least 8dB of room gain at 20Hz (probably more like 10-15dB), and we have our 136dB number if you do a 1 meter in room measurement.

Well stop there because it isn't.

This is pure marketing hyperbole.

Not necessarily, with sufficient power handling and excursion it could be done, and for $36k it should be done. But for at least $20,000 less with four high quality subs it also could be done, and with room mode smoothing to boot. For $35k less a pair of my DIY THTs will do it. wink.gif

The QSub can reach an internal sound pressure level of to 175dB - the equivalent of a commercial jet at takeoff

Sounds like typical marketing fluff to me.

Some poor bastard with too much money to burn might actually get one and expect 136dB @ 20hz at the listening position. A sucker is born every minute.

So honestly is it even possible to hit 136dB @ 20hz with only 1% THD? That just seems like total bull***** no?

Looking over at data-bass.com I can't even find a single sub that has less then 5% THD @ 20hz.
