    Good to hear you have the amps up and running.

    Do you have a high pass filter on the system that could help the woofer from bottoming out.
    Careful, those amps have a fair amount power for those...

    As for the left right issue what happens when you swap the cables at the input to the amp?

    Couple things here......

    First you CAN NOT disconnect the Fan on the MA2402.
    The fan in those is a one of kind fan, they actually call it a "fanformer" the windings on the motor assembly
    are...

    I would try them the other way around as well.

    Actually you could wire opposite so one side of your system has the 2402 on the lows and the K2 on the top
    and the other side K2 on the lows and...

    Unfortunately I never had the chance to do a side by side listening test between a K2 and MacroTech.

    Where I used the K2's they did sound very tight and fast, yes I know those are vague terms!...

    I'm going to say if your really whomping on a pair of MA2402's both on a single 20 amp circuit the breaker will be tripping.

    The K2's were good amps, I put a few in some installations that are...

    Like Riley mentioned about the high pass on the Mackie sub plate amp i'm going to guess is going to be
    around 40hz.

    I'm guessing you have some older Mackie plate amps, I looked up the older...

    I used to have some MA2402 amps.
    You may want to open it up and check for dust build up.
    Also it may come with a 30amp or 20 amp plug on it depepending
    on age and if anyone has changed it out...

    You answered a question in this post that I asked in your other post about the amp.
    Using an amp module out of a sub would include processing for the sub it came from.

    Your subs need to high...

    What Mackie amps are you using now?
    400 watts each for those is kind of under powered for those subs, unless your not clipping the amps you
    have now and the system is providing all the output you...

    Twice I have been the shipper where the FedEx semi truck was in an accident. Packages were about half way to the destination and then days went by with out a tracking update.

    It makes a difference and it worth the effort since you have the tool to do it with.
    You will be applying delay to the woofer to move it back in time to align with sound leaving the horn.

    A few...

    That unit is for time alignment of multiple speaker sound sources to a main stage system such as fill speakers 200 feet away from the main system speakers.

    I have a guess......based on the style of the name badge that they are C43's with the base extension cut off to make them more portable and or into an install cabinet based on the painted cable and...

    What ever they were loaded with had the magnet stuck into the fiberglass, I'm guessing the drivers
    were something JBL based on the square mark left from the pole piece vent trying to draw air in and...

    The earlier Hafler amps and pre amps were available as a kit and pre assembled.
    I still use my original DH200 amp that I built from a kit to originally run
    bullet tweeters in a tri amped sound...

    Let me add to the conversation Hafler power amps and pre-amps.

    Another pro power amp that was good were AB International power amps.

    They appear to be 4331's that have been loaded with the slot tweeter and additional crossover making them a 4333. The cabinets came with the extra holes pre cut but blocked
    over.

    Try rotating the...

    There's no real set position that is exact other than having them both sound the same.

    You could use an audio analyzing program like SMARRT or REW (that is a free download) to use as a reference...

    Keep in mind the JBL 2390 lenses were designed to be used with a baffle behind the lenses, I didn't see anything like that in your pictures.

    Taking bi-amping or tri-amping to the next level with a DSP with a speaker like the Metregon would let you truly time align the drivers. I have never listened to a Metregon but I'm sure it would...

    The solder job does not look "factory" as well as a lot of the resistors being upside down.
    From the looks of the one end resistor and dark look on the board under them I would guess
