Sir ji it a hertz sub not a audison wala.

While on the topic... here is the 3" HF driver from the Genesis Studio 16 set, plays from 300Hz to 40kHz...



Navinji, do you recognize the driver?

The tweeter is having 450 hz FS in the big chamber.

The Illuminator series is developed for home audio application.

Gunbir Phaji it is a co-ax driver. The tweeter is set inside the cone midrange.

It is not the tweeter alone there. But a very nice concept.

I called it what it is... a HF driver, I never called it a tweeter...

Studio 16

"The full range driver crosses over between the midrange cone and dome tweeter using a controlled flexure interface".

Only 1 voice coil, I suppose. Wouldn't that mean that the main cone fails to / does not move at higher frequencies (rubber XO)? Only the 'dust cap' works as the tweeter then?

Simple improvement over ye old whizzer cone fullranges?

Not for car audio but looks interesting..100hz - 20 khz

LBM last time I checked this thread was called "New ICE products for 2008" and not "Not for car audio but looks interesting". We all know there are a million interesting things on the internet, but can we please stay on topic... phaji thoda control karo.

There are lot of drivers which can do this including the one mentioned below. But the question is can they be used in Car Audio Environment successfully.

FYI : "Manger Bending Wave Driver" 80Hz - 35KHz

I fear that is not true..rest you are the guru here.



I think scanspeak driver are used in various application from home to car audio. So considering them only for home audio is not correct.

Also the above informatin is a preliminary details of there new line. Requirement suited for every application will be entertained.

The Illuminator series has been designed to offer the
customer flexibility in sound and cosmetics. For example,
raw frames are stocked with unfinished mounting flanges.
The drivers are finished, including custom mounting hole
patterns, paint colors, etc. according to the customer’s
preference when the order is placed. The flex frame option
allows the customer to get what they want without long
lead times or exorbitant tooling costs – even small orders
can be customized!

Phaji kya kare when it comes to audio control nahi hota. Chalo lets get back to topic before Navin Ji comes back.

High end driver manufacturer always releases the car audio version little later. After making some minor changes and treatment to sustain the environment.

But while designing and developing tooling they keep all the avenues in consideration.

The Alpine F1's are based on the modified versions of Scan Speak Revelator series used in high - end home audio like Krell, Sonus Faber etc.

Similar route is followed by others like SEAS, Dynaudio etc.

Dynaudio uses its famous 7" driver in homeaudio, studio and car audio with changes and modification as per requirement. But the basic tooling and design is exactly the same.

So its quite possible to see some high end car audio brands releasing the speakers based on Scan Speak Illuminator series.

The 2905-9900 was also known as the Revelator tweeter. I have extensively used the 9300,9500,9700,9900 and tinkered a bit with the 9800.

Yes I do but I prefer Jordan's J6 to this machine if I wanted to go 300Hz+. Another cheap option would have been the Fostex FF85K.

SS's modifications to the Revelator series (for the F1) were more extensive than Dynaudio's mods on the 17W75. The stock 17W75 (circa 1987-9) had a Qts of 0.7 and hence worked well in lossy cabinets like car doors. All they really needed to do was to mod the faceplate of the D28.

As far as the developemnt of drivers go (this is general statement covering all manufcturers) I am sorely disapointed with the progress by most manufacturers since the mid 90s. I would have thought that many simple technologies would have become standard on most drivers. This includes using FEA to optimise cone topology, using rare earth mangets and incorporating the same into phase plugs, lighter materials for formers, using edge wound anodised aluminum for voice coils, etc.. Some strides have been taken in the materials used for cone surrounds and basket geometry has become a bit more sophistaicated.

I believe that driver manfuactuers are giving us one improvement at a time so they can strech the sales of their drivers.
