    I’m thinking that question is for me (sorry if I’m mistaken lol)

    Later that day I ran the 402 with the following heads in a fairly low volume comparison with a few basses.

    120 head: sounded good, I’ll say, thought the 120 seems to benefit from a more substantial partner like the 406w to augment a light bottom end.


    Peavey VB-2: 200 watt tuber. This sounded great. Suddenly the bottom was full and there is an amazing amount of flexibility with this particular combo. One of those rare situations where almost any setting is still useful. Very nice.

    330 Head: Now we’re talkin’. This combo makes me re-think how big is too big for a few more rooms that I routinely work.
    Egads the tone AND flexibility. Power seems no issue even though these were low-volume assessments.

    The EV Force speakers sound excellent to my spoiled-by-vintage-original-white dome Eminence ears.
    The specs and reviews place their behavior very close to the factory originals.

    Nice man. That 120, did it came standard with the black eq plate or was it modified?

    I decided to part ways with my 126 combo by the way, will trade it with a SWR 350X that I will end up selling probably sooner than later. Need to prepare myself for a 320, 330, 370 popping up, still regret not going for the 320 when I had the chance. When having a 220 and 406 in the garage, the 126 has not been used since

    It came that way. I’ve seen 1 or 2 others that way.
    Found on GC used in excellent cosmetic and operational condition for $120.

    yes the Acoustic logo lights up in the front. It fades on and off. I was surprised the LED still worked

    Anyone knows if the 15 inch speaker in the 126 combo is 8 or 4 ohms?

    Seeing that the 126 Combo is 100 watts, I would suspect that the speaker is 8 ohms. Unfortunately, the Acoustic product brochure that I own doesn't specify what the Ohms rating is.

    From the notes I've taken, I'm pretty sure both the 126 and the 136 before that used the same 4-ohm 15" driver, Acoustic house number 130024.

    It’s 4 ohms to allow the 120 amp to produce its full 125 4ohm rated wattage.

    Thanks for the swift reply. Unfortuntaly I noticed the cone of my 126 driver is ripped on the bottom, and produces an awful noise when the E is hit at too high volume. I have two original square magnet 8 ohm drivers but this means they are not correct. Damn what to do now

    This is what I would probably do:

    https://www.musiciansfriend.com/accessories/eminence-legend-ca154-15-bass-speaker/h67863000000000?cntry=us&source=3WWMWXGP&gclid=EAIaIQobChMI1vHz6pCr2wIVj4zICh1jmQeUEAQYASABEgKcPPD_BwE&kwid=productads-adid^221957295827-device^m-plaid^376911716327-sku^H67863000000000@ADL4MF-adType^PLA

    It’s a fairly close match.
    Of course that would be after looking into reconning the original, if I have it.
    Some speaker guys can recone with period accuracy.

    Indeed the Legend CA154 could be the solution. I have no clue on a good reconing specialist, maybe worth to check as I have two other square magnet 15"s lying around

    Looking to load my empty 406 - should I aim for a 2ohm total to get the most out of my 370?

    Not sure if working your 370 to its max potential is a better long term plan than simply matching the wattage and very important sensitivity rating as the lower power handling drivers often rival total volume output of heftier woofers due to higher sensitivity or volume per watt. More conservative 4 ohm rated operation (275 watts vs 375 @ 2) with properly matched sensitivity ratings will yield great yet sustainable results long term. That was a major part of ACC’s strategy and resultant high volume reputation.

    I have found a CA154, for about half the new price, and also got an offer to buy a JBL E140 8 ohm speaker for about the same price (50€ without transport). Maybe the JBL would really be the perfect match with the horn of the 126, even if it means I need to sacrife power of the 120 by running at 8 ohms. Any ideas, besides buying both? :)

    Personally all my ACC gear closet runs at 4 ohms. All my cabs are 4, so unless I stack 2 cabs, which there’s no need for it’s 4.
    I’d be afraid to “commit” to running at 8 “permanently” w/o being able to test first. So trying the JBL makes sense to me tonally, not so much efficiency-wise.

    Another way I would evaluate is output vs weight. Any time I can increase output safely w/o weight increase I choose that option. 8 ohm operation with ACC gear (which was planned to run at 4 primarily-2 secondarily) is counter-efficient because the weight can’t easily be changed, but ohmage can.

    My optimum setup would be to find a 4 ohm woofer with at least 150 watt and 97-100 DB sensitivity rating.

    EV Force 15” nails those and has very good high frequency repro as well. Those are traits to make the 126 as efficient a tone machine as was possible in that size in the 70’s.

    The more parameters you compromise on the less satisfying it becomes to move and therefore use. Unless your plan is studio use, that is.

    Great stuff. James Gang played Michigan State Fair that summer ‘70 or ‘71 (in Detroit) and I could swear they were using the exact same gear when I saw them.
    I was just getting started and paying close attention to any acts I could. They definitely stood out.

    Scored me a Legend CA154 to load the 126. Oh yes and picked up a 125 on the way.
