Just got an email through from a Christchurch Bose dealer about an exciting new wireless speaker - $5k, for just 1, but it has a 4500watt amplified built in and is capable of notes down to 14hz.

 

is it April1 already?

They probably don't plan to sell too many of these things .... doesn't look too appealing either

Funny how this incredibly powerful speaker that they claim is "4500 watts" plugs in to a 3 pin socket with a plug rated at 2300 watts or so.  Oh - it's "peak".

 

Then there's the spec that states SPL at 1m = 108dB.  That's not very loud.

 

I've got an active sub (professional PA sub) in our lounge room which is rated at "only" 600 watts RMS.  It's quite compact, but weighs about 70kg.  Max SPL is 128 dB.  That's a hell of a lot louder for a hell of alot less power.  To explain how loud, it's serious rock concert loud - your vision distorts from the vibration, things fall off shelves, children cry, cats flee.

I'd like one of those. 128dB at what lowest frequency? And to add - neighbouring partygoers go home.

I think it's fairly flat down to about 50Hz (and it's got an active 23dB/octave cutout above 100Hz - so we're really only talking about one octave), then loses about 3dB down to about 40.  IIRC that's about (41 Hz) low E on a four string bass guitar. Those low frequency SPLs are a bit of a difficult issue to measure.  The subs need to be on a floor to work, so some hypothetical test in an anechoic chamber is meaningless.   At those frequencies - you feel it as much as hear it, even at quite low volume.  It makes me realise how lame "hi-fi" is - if the objective is to reproduce live performance.

 

For "home theatre" (as opposed to music), subs might be designed for effects rather than music, at the cost of reproducing lower (than 40Hz) but with lots of first harmonics (seeing as Bose is in the thread title). There's a big difference between the "doof doof" of first harmonics from a kick drum or bass from most so-called hi-fi, and something that feels like it's knocking some air out of your lungs like sound reinforcement systems at concerts.  You can achieve the latter at home, at surprisingly low cost, but god help your neighbours.

They have them on demo at Harrods if you find yourself in London. Don't sound bad for the size really, but you would hope not for the £££.

Best bass I ever felt was with $20 worth of Aura bass shakers, removed from their gaming vest thing and installed in the sub-frame of a couch, being feed from splitting the LFE channel of my amp. Didn't need to have it loud at all, but you could literally feel every bass note. Made the action films such good fun

We saw these in London and France recently, he isn't kidding in that review when he says you can feel it in your chest. It was super impressive.

There's a good use for $119,760.00.... although there may be some sort of price break at that level...

Haven't these been around for a while now?  Or is this a new model?

 

They had them in stock at Paul Money in Auckland when I was last shopping for a new amp and that was over a year ago.

They have been out for a while and a few stores in Auckland have them on display/demo. I heard/saw them at The Audio Consultant in Ponsonby/Grey Lynn Auckland a while back. Great sounding piece of kit in my opinion. Bass is impressive for a Box that size. Expensive but they come in a couple of hi/lo powered versions. Devialet make some pretty good audio gear..but expensive. Give it a listen if you havent heard one...might surprise you.
