Dynaudio Consequence Utimate Edition??

This is interesting.

Wow....quite a beautiful masculine looking speaker.

That is an odd looking duck, isn't it. Idaknow, I absolutely love my Dynaudios, so I'd imagine those really would b something to hear.

That's a heapin' helpin' of speaker. Just over 16"x24"x52" and 154 kg (338.8 lb). I'll find out how much they will sell for.

I found a review from last year that indicated they listed at £18,000. The module for everything above the bass rotates for the best listening angle, too.

The text also mentions a woofer completely enclosed inside of the speaker... Does anyone know of anyone else doing this?

Does anyone know what they mean by "Variovent" construction?

Variovent is an aperiodic membrane, which is basically a diaphragm that moves with varying internal pressure.

They have used them almost since they started making finished speaker systems and may have sold them as parts before that. They're not terribly expensive, either. IIRC, Madisound sells them.

They use a "compound woofer system" that's been used by Dynaudio before and also by Linn, and others, as far as I know, the idea is that it's two similar drivers and the internal driver sits within a closed cabinet, and "tricks" the outer driver to see an infinite size cabinet

My dealer just had an event 2 saturdays ago featuring the Consequence SE. These babies are just marvelous and they do not sound like a humongous speaker at all. Although it requires a big stage to perform at it's best, not to mention the need to mate it with stupid expensive and capable components After listening to the Consequense SEs, I could not even listen or look at my Dynaudio Blue Sapphires for a week

 

[haraldo]

He he he

That's the downside of listening to such equipment, it's just incredible what a very good system can do for the music experience...

And I have enjoyed all the Dynaudio's I ever listened too... I would really like to hear these speakers

Wow... and the Sapphires's is not exactly low end.....

Ima-dyna-ho

fixed.

Hey, why are the speakers upside down?

 

[Warpdrv]

that is the worst possible layout of drivers possible....

Tweeters on the floor... hmmmmm

Perhaps it looks strange, but some of these "upside-down" speakers works very well, like what they do in the much more affordable Contour range...

He he, and tweeters are not at floor, really

 

[Warpdrv]

Tweeters are generally very directional, I'm not sure how putting them so close to the floor can be very attractive in design or implementation..... strange... I would like to hear them, as Dynaudio doesn't make cr@ppy speakers - I have found them to be pretty darn nice....

You're right, tweeter is almost on the floor, and yes
You should lose some of the upper top end with this setup, because of tweeter beaming...

We discussed these speakers not long ago. This is what I posted back then.

There is a reason, the tweeter is at the bottom, as the Consequence uses first order minimal phase shift crossovers. The result is an upward 15 degree tilt in the lobing pattern of the drivers. So even though the drivers are facing straight ahead, they are in fact firing 15 degrees upwards.

In my last post you will see the history behind all this and my history with this approach. My rear surrounds are my old monitors from Grand Forks, and in my case the drivers are high with 15 degree downward tilt. The picture in the post will make it clear.

These speakers turned out to be a lucky accident, as they are now perfect for the rear backs, especially when playing an SACD like the Rilling Britten War Requiem, that has a lot of performers behind. I will post about this remarkable SACD set another time. But they require rear backs as capable as the fronts.

Why use Compound loading on the woofer system, it's very inefficient and presents an amp load with an impedance that's half the normal, since drivers must be connected in parallell I assume...

Wouldn't you get just the same performance benefits by using a sole driver in a properly loaded transmission line, is there really any benefits to compound loading at all?

You have put your finger on a problem. The only advantage on Isobarik enclosures is to save space. Vas is halved. However the enclosure volume is not halved as you have the displacement of a whole driver and the connecting tunnel to add to Vb to get Vt. You are right impedance is halved and amp power is doubled over one driver for the same spl. Actually it is worse, because if you used the drivers both mounted on the outside, then spl would be up 6 db versus one driver, but Vas is doubled so the enclosure would be huge. So that arrangement is actually costing 9db in spl. So when ever you are at a demo of those speakers the amp is hefty.

Not only that the parallel network required, and I'm assuming they are still using it, has horrid phase angles and impedance curve. That is probably the most difficult amp load around. However the speaker does sound good if you can afford it and the maps to go with it.

So do speakers need to be huge? No but it helps an awful lot.

Well...Just FYI the one closest to the floor is a super tweeter and not just a tweeter

Agreed.

Anyhow, If a person not having seen the driver configuration of these speakers, walks in the room and listens to the Consequense SEs with the grilles on, he would never suspect that it has a "unique" driver arrangement Trust me, I've actually heard them 2 different times at different rooms with different associated equipment and the imaging and sound staging IS NOT INVERTED and without audible high frequency reflection from the floor/carpet.

The drivers have to be in that layout because of the crossover. As I explained in my post the tilt is 15 degrees upwards, not to the floor!

I know that and I read your post and thread before replying! I was merely letting the other members know based on my actual experience with them, that the Consequence SEs DO NOT have an INVERTED IMAGE.
