Can the EP2500 be daisy chain

As far as EQing multiple subs in different locations, Sonnie sez he’s had the best results simply EQing them all as one, with a single set of filters:

As far as the eq'ing all subs as one... I do not know the technical aspects of it, but I do know it works regardless of the location of the subs. I also know that any time I have tried (and I have tried many times) to equalize two subs independently, that while the individual responses have looked very good, once they are combined, the overall response looks awful. It has never... and I emphatically repeat "NEVER!" worked when I have tried to equalize subs independently for an overall smooth combined response. Quite frankly, I do not recall anyone ever succeeding at doing so... and it does not make sense that it can be done either.

As far as daisy chaining the EP2500, Pg. 7 of the manual says that if you’re using parallel mode, the Ch. 2 input becomes an output that can be sent to another amplifier (of course, if you’re using XLR cables the gender is backwards).

Things are a little different if you’re bridging the EP2500, which I assume is what you’re doing since you’re using 4 amps with 4 subs. Since each channel’s XLR and 1/4” TRS connections are paralleled internally, theoretically all you’d have to do to daisy-chain additional amps would be to utilize the unused input to send the signal to the next amp. IOW, if you’re using an XLR cable between SMS-1 and the first EP2500’s Ch. 1 XLR input, you then could use a balanced 1/4” TRS cable from Ch. 1’s 1/4” jack to send to the second amp. Then another XLR cable between the second and third amp, etc.

Speaking of the SMS, according to one of our Shack members you really can’t get accurate equalizing from it without using REW and entering filters manually. If you have to go to that trouble, there’s no reason not to go with a BFD. It’s cheaper, to boot. If you’re set on the automated route, it appears the Antimode or SVS-AE1 are better options for the money.

I used to own the SMS-1 and I can tell you that it's not as simple as just flattening the response with filters. They don't tell you that in the manual though.

Creating a flat response is not good enough. One can create 10 flat curves and still have completely different sounding results every time. With my SMS-1, a flat graph equated to boomy, sloppy sounding bass and I never understood at the time why that was the case. Surely I should be getting nice tight, responsive bass, right ? Well, no, not really, although the level of bass had been reduced, the filters that were applied did not target the mode center frequencies with enough precision and the display of the SMS-1 was not accurate enough, in my opinion, to deal with those issues.

Like the other poster mentioned, it's essential that you use REW to input filters and see the results as the SMS-1 display is not reliable, in my opinion. So for now, it looks like the Anti-mode is the best (and most affordable and easiest to use ) automatic EQ on the planet.
