    it seems to be an exception to the rule
    It's an old model the ELX-200 series is the current version. If you compare the amp modules you will see the ELX amp is very basic and doesn't have any of the DSP features all the newer boxes have.

    Max. Measured SPL3 134 dB


    should a bassbin not normally go as far as 200hz? i always thought that was roughly the crossover point
    No, a sub generally should not be used abouve 80-100hz. The ELX118p isn't bad sounding but the main complaint is it just doesn't get very loud.

    what do i really need on the DSP?
    only thing i can see that im really missing without it is the phase reverse, but i believe i can buy a connector that will do that for me.

    Was going to say this. Most people including myself will setup a cutoff frequency at around 85 Hz. Anything above will start messing with resonance frequencies from low mids. Try a 200 Hz cut and find out how messy/bloated it sounds....

    Bass bin is what the low frequency part of the system was referred to before subwoofers were invented, roughly 30 years ago.

    The P stands for powered.

    Everything that it offers.

    actually, just to add another sub to the mix here
    what are your thoughts on the Mackie Thump 18s compared to what we have already spoken about?

    and does the rear firing design offer any benefits?

    Rear firing, side firing, down firing, it doesn't matter, because the output of subs is omnidirectional. But the Mackie isn't rear firing.

    I have one that I bought because it was inexpensive, has decent performance and I don't use it very often. It's not bad sounding but not the best either. However it's quite bulky and rather heavy, so it's not a a one man lift for most people.

    I wouldn't touch it with a 10ft pole. That is a bandpass sub which often don't sound great but it's also a Mackie and they have terrible reliability these days, I had 4 thump boxes at one point and all of them failed inside a year of new. I replaced them with EV boxes and have had zero problems since.

    ok dont wanna bore people with my questions but two other options have come up now
    how would you guys think the LD Systems ICOA SUB 18 A would stack up against something like the EV ELX200-18SP

    i had the benefit of renting the LD last night, and what can i say, to my humble ears it was amazing! i thought i would need 2 of these, but one seems like enough.
    it says it does as low as 29hz, seems like it does go nice and low in fairness.
    downside is its 44kg but has very nice wheels.

    the EV only says it goes to 47 hz, that seems very high to me, is it not? but its 29kg


    specs below
    https://www.thomann.de/ie/ev_elx200_18sp.htm
    EV ELX200-18SP
    Bluetooth
    1200 W class D amplifier
    Max. SPL level: 132 dB
    Frequency range: 47 - 105 Hz
    Dimensions: 636 x 598 x 518 mm
    Weight: 29 kg


    https://www.thomann.de/ie/ld_systems_icoa_sub_18_a.htm
    LD Systems ICOA SUB 18 A
    Power: 600 W RMS / 2400 W peak
    Max. SPL (sound pressure level): 133 dB
    Frequency response (-10 dB): 29 Hz (depending on the preset)
    Optimised bass reflex ports
    DynX DSP with 4 application presets (3 crossover frequencies, cardioid mode)
    Switchable signal polarity and adjustable delay line for up to 10 metres
    Dimensions (W x H x D): 626 x 672 x 637 mm
    Weight: 44.3 kg


    i have already placed an order for the LD as of now, but i have a week to change my mind, while they get in stock levels so do you think i have made a good choice? or a mistake
