old EV MT4 designs?

Just curious if anyone had any designs for the old EV mt4 bass bins (4x18"), or the manifold loaded tops that went with them (4 x 1" i think)?

any help much appreciated

Cheers,

yea...just checked...(sorry.....my bad)

EV-MT4b it is..........

so......anyone?

 

First met at Bad Neuheim in Germany at an EV Seminar with the venerable Don Davis. After the seminar there was a demo of the newly introduced system. The venue was a 500 people house in fan shaped architecture. with about 250 of them  and with fairly dead cinema style acoustic.

First track played was a cd production from the first THX sound logo of that time.

 

What the hell, sooooooooo loudddddddd

 

The system energized the theatre with astounding amount of acoustic power and very low distortion or listening fatigue. No buzz, cracks et cetera at all. Just good sound, as we all listened. Crest 01 Series were the amps.

 

Next I had the occasion to listen to UB 40 tour in large (about 30'000) people in very bad rooms.

 

I felt the system had very bad alignment somewhere because arrayability was poor, or maybe severe phase concern happened. Then, the room was surely the worst possibile, a kind of places we call "Palazzetti Sportivi", in those you really cannot play almost anything except, maybe, large simphonic repertoire. 

 

The processor used by EV at that time it a was a stupid analog crossover, despite the work of Siegfried Linkwitz on filters, (now arrays sound better also because of the processing power of digital units).

 

Surely it was the loudest single loudspeaker system I ever heard.

 

No had occasion to place my hand at the mixing console with them, nor to try to lift them up in the truck, but that loudspeaker (system) was something really new that changed something in the the industry.

 

Large system of MT 4 were used in vertical line array fashion arrangement, long before any specific line array enclosure appeared on the market, but in some places due to weight they've been installed on the ground or stage (dont do it).

 

The weight of the package was maybe it first and foremost drawback,  while the summing device invented by Cliff Henricksen was surely its most elegant feature.

 

Would be good to have a pair of these to impress friends at home.

My only knowledge of these comes from the Hacienda...

(I could be mistaken but i think they only had 2 a side...and THAT WAS PLENTY!!!!!).....

 

Im just sick of fooking about with smaller cabs (outside anyway)........

I want something i can litterally roll out the van and leave where it is to do it job...From what ive heard they need very little engineering or looking after. (im getting lazy..........or is that busy?)

 

Thanks for the plans by the way....Any ideas on the manifold loaded top box (MT4h is it........erm.....4 x 1", 4 x 2" 2 x 10"....or something to that effect....)

 

peace and thanks,

I got a pic of a pair of them used at some disco or wedding. Will try find that pic in a minute, its somewhere on a disc.
