4344 tri-amp?

[Toro Italo]

Hello everyone!

For some time I follow with interest the forum that has inspired me with the realization of my beloved 4344 MkII clone (entirely built of aluminum).


At the moment, my 4344 are bi-amplified. Bi-amping brought significant improvements in terms of acoustic performance compared to the mono-amplification.


I was wondering if any of you had experienced the tri or quad amplifier on 4344. In the event, I would like to know if I can expect a further improved performance.

In other words, spending money on the adaptation of the system then justify the acoustic result?

Thanks a lot for your support which is very appreciated.

Greetings from Italy,

I'm sure many here would love to see photos of your creation.

Welcome to the forum!

Hi BMWCCA.

Here below you can find some pictures of the customized 4344:




The cabinets are completely built with 6082 Anticorodal Aluminum plates, 20mm thick, except the front panel which is 30mm.

They are HEAVY and SOLID and practically do not resonate

I can send more photos if they are of interest.

Thanks,

Toro

WOW!! That's amazing work - thanks for sharing!
Glad you have a new thread for talking about this system!

Impressive indeed!

It looks like Guido build the networks: http://behringer-electric.de/index.p...=79&Itemid=203

Thank you all! I assure you that 4344 is even better when seen live.


I confirm that the passive crossovers were made by Guido, which I entrusted also reconing of 2235 and 2122. Guido is a true professional and did a great job. Also he continues to support me (and bear me...) with my crazy and exotic ideas .

BTW, have some of you triamped the 4344/4345?

Thanks again,

Good evening gents!

First of all, thanks to JeffW for the suggestion and to Mr. Widget for having moved the thread in the correct section.

Thanks also to Space is the... for his comments.

The aluminum plates were first micro-sandblasted and then chemically nickel plated.

Unfortunately the result did not meet my expectations (you can see the effect in the interior of the cabinets) . In any case this treatment makes the surface very hard and resistant.

So I decided for a classical liquid coating (epoxy metallic painting and successively transparent two-component painting).

Looking closely, the finish is spectacular (I also carefully selected the paint shop...).

I'll post some pics of a special aluminum 18" subwoofer box I am actually working on .

Best regards,

Mirko

Wow!

Exceptional workmanship and they look great. Please post as many pics as you can provide.
I'm very interested in the machining if you gave any pics of that process also unfinished components.

Thanks Mac

Here is a man after my own heart! I love metals and machining.

This is one of the coolest projects I have seen in a very long time!

It appears the dazzle of this project has obscured your original question.

I have not had 4344's but have gone as far as five way full active on my own systems. Passive or active it takes tools, skill and experience to really integrate a system as complex as yours really well. Is it worth the effort? In my opinion? Absolutely.

What are you thinking?

All the best,
Barry.

Hi Barry.

Thank you very much for the appreciation!

As for the multi-amplification, I'm seriously considering going in "all active". I'm currently using a fantastic electronic crossover Pass Labs XVR-1, but I intend to soon add a supplementary main unit to set at least an active 3-way.

At first I would just set cutoff frequencies identical to the original (290Hz, 1.3KHz, 10KHz), working only on the levels. Afterwards I could experience slightly different cutoff frequencies (being careful not to damage especially tweeters and super tweeters).

Besides, I just can not put the word "end" of this project ... since it is giving me too much satisfactions ...

Best regards,

Mirko

Ok, the BASS^3 looks a bit like a washing machine (and also the dimensions, in effect...) but it is not yet finished :

Thank you Mac.

Here below you can see additional details of the assembling:












I should have some photos of the milling phase, performed on two different centers (Yasda and Okuma). I will verify.

Thanks Mirko , I guess you work in that industry ? Nice to have such tools at you disposal
