Guys here is another one :

This one from Tru Technology's UK distributor. Mr. Singh



Toyota Altezza Supercharged







The legendary Clarion HX-D2 (aka DRZ-9255) above is a controller for UCS Pro digital equaliser and crossover.



Three TRU Technology Copper Series amplifers with stinger cables and distribution blocks



Another view of legendary amplifiers, the amps in order are C7.2 (2 Channel), C7.2AT (2 Channel 15Watts All Tube amplifier with EL84 Output Tubes and 12AT7 preamp tubes) and last one is C7.4T (4 Channel 100 Watts per channel Hybrid Mosfet amp with 12AT7 x 2 preamp tubes and 2BH7 x 2 driver tubes). All amps are Kimber Cable wired. And there is a UCS Pro processor at the back.



Lovely glow of the tubes (in 7.2 AT) and 7.4T (with blue LED's)



Complete view with three huge amplifier and RE sub in ported enclosure.

Drool guys...this is serious High End.

[navin]

that sub is beautiful. a very good compormise between space and bass.

[Autophile]

The subwoofer is RE Audio XXX in a ported enclosure made of plexiglass.

These subs are designed and engineered by Image Dynamics and are meant for serious SQL (SQ + SPL)

[navin]

what is the Vb of the sub?

[Autophile]

Don't know Vb..its not specified rest of the specs are as follows:

Fs = 27.0 Hz
Re = 1.9 DVC
Qms = 4.52
Qes = 0.44
Qts = 0.4
Sd cm2 = 480
Vas = 123.3
Xmax = 32 mm (One way Linear)
BL = 17.1
SPL 1W/1m = 85.9
RMS = 1600 W
Max = 2500 W

[navin]

Vb is Box volume. I would assume it to be
60" x 12" x 20" x .8 ~ 6 cu. ft. this is from visual inspection only.

[navin]

I would like to know Mms and Cms although I would guess that it would be a heavy cone with a soft compliance. if this is so please advise the client to not use this woofer facing up or down.

[Autophile]

Navin, The driver is neither facing up nor down. It is firing towards the back seat with the ports terminating in the parcel shelf.

The sub which has got such a heavy motor structure with diameter equivalent to cone. The issues related to heavy cones and compliance is already out of question. And also don't forget that this driver need 1000Watts continous power.

This subwoofer is capable of generating very high SPL in which the motorstructure and the powerrating is very important

[navin]

yeah i saw that huge magnet. Ouch. it even look like one piece from the photo not like Focal's Audiom series wher the magnet though huge is multiple smaller magnets stacked.

It probably has dual spiders as well. still with a heavy cone (it might have) you can have cone sag. I know that the driver is facing forward but i wanted to caution the user in case of any future application. I tend to use drivers from an older application to a new one and try different boxes etc.. so it was just a friendly caution.

[Autophile]

The owner of the car is a seasoned installer and one of the most respected people in the car audio business. He is our peer as the UK Distributor for Tru Technology and that total install costs upwards of 15000 pounds. I don think he needs any help because I cant find anything wrong in that install.

As far as the sub is concerned it has solid piece double stacked magnets and pulp-carbon fibre cone. The magnet arrangement of Focal are still there in their current Utopia series subs.

[navin]

neither can i the install is perfect. but even the best can make mistakes just ask them.

[Autophile]

The best part is in most cases...the installer themselves know abt the mistakes that they have made and no one other can :-)

[navin]

LOL! and they dont bother to correct it?

[Autophile]

Honest & good installers do...dun know about the others !!!
