    4344 tri-amp?

    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,

    Toro

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

    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

    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,

    Mirko aka Toro

    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

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

    Best regards,

    Wow! I've seen aluminum baffles before, but never anything like this. Amazing attention to detail. Congratulations.

    Thank you Rusty!

    In fact, nothing was left to chance. I designed 3D models and machining was carried out with the utmost precision and attention to detail.

    Best regards,

    Mirko

    You should consider having the thread moved to the DIY section, it's sort of buried down here in Electronic Crossovers.

    And amazing work on these, just stunning pieces.

    Hi Mac.

    My work is another, but being a mechanical engineer I have a great passion for the metal and precision machining. BTW my brother in law is the owner of a company that carries out machining with CNC machines, so it was not hard...

    Best regards,

    Mirko
