If anyone local to 60504 or so wants to go in with me on some of these shoot me an email or hit me up via pm.
Your getting a deal. I picked mine up from the freight company and was around $200 for 2, and if you need a truck with a lift gate to have it delivered to your door, it’s another 80$ . Picking up from the shipper is definitely the way to go

Reason is this is the frequency response published by chane. Black is the raw response.

https://www.chanemusiccinema.com/for...1&d=1524746036

The drop starts at 60 and is down about 18dB by 20hz so I'm just equalizing the opposite of that to get a flat response. Am I thinking about it the wrong way?
I wouldn't do any response shaping until they are in your room and you take a base response sweep with REW. Fwiw I don't think 10-15db of shaping is out of the ordinary starting from no dsp. Many OEM's apply a significant amount of dsp to the response to flatten the response before putting that model up for sale. You can't get a smallish sealed sub flat without signal shaping no matter what driver is used. Look at SVS subs for example. You can tell subs like the SB2000 have a ton of boost applied down low by how flat the base response is when measured 2m rms outdoors. Then look how much upper end bass output there is in relation to low bass. The boost on the low end limits the high end, but SVS does a good job of employing compressor/limiters to keep things from sounding bad or causing damage. The dsp will clamp output down low as the sub approaches max output and let the higher frequencies play louder as you turn the volume up. The problem with low xmax drivers is room correction boosting frequencies down low on top of a sub that has had OEM dsp shaping applied. There isn't a lot of excursion left on the table to add the extra boost. That is when you add more subs. Sealed subs extend the deepest, but you have to keep adding more until you can get the clean output you seek down low. That is why the craze right now is low tuned ported subs. a couple LT ported subs can equal 10-12 comparable sealed subs.


That being said, at the price point these are selling for, a quad setup would be most would ever need. To bad you missed out on that Suntron amp Chane offered to drive these. They were closed out for 249.00.

I run 2 of them nearfield off an Inuke3000. I have the amp in bridged mode and the subs wired in
parallel. They work well for me as I have them. Well worth the money.

I am contemplating getting 2-4 of these and some Dayton SA-1000 amps. How do you think that would compare to a 2-PSA sealed 18 setup?

These were similar to the older PSA S1800 subs except I would say the ICE amp is a step up over the Dayton in quality.

The S1801 would likely be 2-3db ahead in the lower bass(<30hz) 1 vs 1.

3 dB more is really close to the UM-18 in max output.

Nothing right now

So is there an amp that you would recommend with these? I would like something with a built in EQ if possible.

I’m either going this route or leaning towards HSU ULS-15 Mk2 subs...

I didn't mean the Dayton's were bad, I was just giving you my opinion on the difference between the 2. Dayton or Behringer DSP will work fine.

So they arrived today.

Room is 12x30x9.

REW is seeing a response till like 14 hz before any dsp. No trends at all but a couple nulls/bumps. Smoothed these out with the NX3000D. When I run the sweep at a relatively high volume the driver barely moved. Jon Lane mentioned I should watch drivers to make sure they don't move more than an inch and so far it isn't close.

I don't want to bias anyone towards these though S I've said before, I listen quietly so to me flat response is a bit more easy to achieve when my goal is like 80dB not 105. Speaking of that though, 1 of these gets 99dB at 20Hz with CEA 2010 so even if you listen loud 2 of these in a small room would be ridiculous.

Do you think that it would have the same response with the Dayton amp? I really wish I could get the Chane amp, but those are nowhere to found!

I know next to nothing about this stuff tbh. I got the Behringer NX3000D so I could DSP. I have 2 sharp 10 dB bumps at 20 and 50 Hz to compensate for the nulls. Now when I play CEA 2010 bursts at 16Hz I can hear a legit response which is amazing to me given my last sub dropped off a cliff at 24Hz.

I don't know about the Dayton amp, sorry.

I like the behringer much better than the dayton amp, used both. The berries are stronger and extends deeper. Many people love the new pro drivers, especially the 21 inchers, these have the same response as those but with less excursion, two of them will have more excursion than the 21 Lavoce or B&C DS 21.

I will add that the Behringer is not usable without the fan mod. I got the noctua NF A8 and the difference is complete night and day. That thing sounded like a plane taking off without ever getting quieter. I wouldn't get the Behringer if you're not planning on swapping the fan or it's going to be in a closet somewhere with almost sealed doors.

Does anyone know how these subs compare to the Dayton 18" kits sold on parts express?

I have one I could sell you. PM me.

 
If you take yourself too seriously expect me to do the exact opposite...

I just placed my order for 4 Chane SBAE 118 subs!

I am not even sure what I am going to do with that much firepower in my 13 X 17 sealed room... lol

I like to consider overkill just "future proofing"
