Stereo Integrity's new HT Subwoofer - Page 31

PL,

Lulz on your avatar sig. Priceless.

Im going to a buddy's house this saturday who has both the SI and Dayton's in dual opposed boxes. There's another person going with a SubM, im gonna ask him and see if he'd be up to bringing it over.

I think that would make a GREAT comparison.

Interested to hear what you guys think! Will they both be using the same boxes and same amp?

I thought they sounded very similar - with the dayton having a slightly 'deeper' tone, but that's only to my ear and based only on some short listening sessions. Realistically in a blind test it's likely I couldn't tell them apart. I hadn't yet grabbed measurements and really didn't get to compare them as much as I had liked to since the one SI driver had an issue. I do have 4 more of the SIs now but it will be some time before I have them up and running in boxes.

I'm going to be making some speaker stands next for my new mains and I can't get the idea of cramming more subs into the stands out of my head.

Im not positive, but i think the cabs are the same size. Same for the amps.

Are you guys adding Polyfil in your boxes running these, or is there no need? Dual opposed at ~ 6.5-7 cu ft. should be good right?

Props to that Submersive owner if he comes through... Those three players were going to be the primary focal point of Rilla's 15 Dec GTG. Receiving a damaged SI Sub and not being able to find a Submersive owner interested in bringing out their their toy totally shat all over that idea...

Yeah no kidding huh?? To be honest after this comparison I would not be surprised if he did some changes to his bass system. Dont get me wrong his dual SubM's sound great! But after my last visit to his place i got the impression that he's looking for more. And unlike myself, he's got plenty of room to go with the Popa-special!

There the same size, approx. 6.5cuft. They will both get about 2000 watts/1000 watts each driver.

I only had a chance to take a quick 30 min listen a couple of nights ago but they do sound pretty similar.

Cool, looking forward to what you guys think. The consensus over here between the Submersive and the dual opposed Dayton was that it was very close in both output and sound quality. Most scenes the max output was almost the same db level. When push came to shove though on the x-men beach scene, the Submersive made a couple bad noises and the Dayton cruised through it.

Andrew I've seen you post this before and this is what makes me just a touch nervous. Like I've said, the Dayton sounded very similar to the Submersive - on movies it would be really hard to tell them apart. However, for music the Dayton has this "weighty" sound to it that may be what you describe as a "deeper tone". Whatever it is, I love it and hope I won't be losing that with the SI's. I need to chill, but I'm paranoid by nature. I guess if worse came to worse I could probably sell the SI drivers and buy Daytons, hopefully it won't come to that though.

I wouldn't sweat it. Andrew made a quick assessment without any eq'ing etc. The Si is spec'd for a larger box so this might have some bearing on the sound discrepancy. This is all talking out my butt, but I think the Daytons might have a slight advantage in a smaller cab than the Si's.

Is this me?

If it is, thanks.

I've been called many things in my day, but never glue. That's a first for sure...

Someone called me an ambulance once.
Okay, not really.

LOL. I was lazy and decided to slang abbreviate your name.

Gorilla is Rilla, Passing Interest is PI, you get the point.

This. The response from both the dayton and SI model almost identically, with a slight edge in output to the SI. Definitely no need to worry man. Now get started on those things!!!

Selling two Subm's would definitely free up the funds!


Man, with the T/S parameters being soooo close in almost every regard, it makes me wonder if this "deepness" could be from the cone matetial itself? Aluminum vs paper...or is that way out in left field?

Reminds me of my comparison between the SVS pb13 ultra and the rythmik fv15hp. The rythmik was super clean sounding. The SVS had what I called a "thicker" sound to it that I also preferred. Thing is, the rythmik was aluminum and the ultra was a type of composite so this would be opposite. Although they were very different drivers beyond their cone material.

I'm betting it had to do with EQ.

When we did the SubMersive and Dayton listening session, the frequency responses were almost identical. Like, it was scary how close they were. And I agree with carp, there was some (fairly slight) weight or thickness or something to the Dayton's, I subjectively liked it, but several of us agreed it was there. *shrug*

mrsmithers

it was my understanding they were purposely eq'ed to be close frequency responses for that comparison, no?

Dang. Isn't the Submersive dual 15"? That's impressive that it can keep up with the dual 18's. up to a certain level I'm guessing.

I'd like to compare the SI 15's I bought to the SubM. Turns out I just happen to have a DO box built to SubM dimensions...



Now just need a SubM to see how the SI's stack up...

No eq for either, but he did boost the low end (it's not called that but I'm ignorant and don't pay attention) to the Dayton's using the minidsp.

Nosir, no parametric EQ used at all. Just a SubM on top of a DoD, level matched.
Correct. You can make an awfully small single woofer "keep up" as long as the sweep is run down in the noise floor The SubM is an awfully capable subwoofer system, it's more bass than a huge percentage of people would ever want and it almost always sounds exceptionally smooth while doing it. carp's reference above to the X-Men: First Class beach scene is the first time I've EVER heard it make bad noises (and subsequently the first time I've seen either the yellow or red light come on..we saw both). Also Gorilla's Dayton's would have a touch more output than mine, and you could get a touch more with an even bigger box but the excursion would also increase and we're talking, if I remember right, like 1 dB difference between 7 and 8 cubes in a sim.

Correct, there was an L/T, I think it was 6dB and I wasn't comfortable doing more than that given that we didn't have time to test and fine-tune after taking the SMS out of the chain.

and just to add. were not both the SI drivers Gorilla had prototypes? not to mention there was something wrong with one. i know how you feel carp, but im personally not worried about it.

More money than sense.

This!
I won't give my subs away but things have to happen in my direction for me to change. I would gain zero output because I could turn mine up already and just have it coasting, the SI's would be turned down even more. Still I am thinking the dimensions of the boxes would perfectly create a baffle wall or I would build a baffle and just put these in the wall.

Looks like the Submersive is a GO!

They are about 7.5 cuft each so they would do well with 2 each at 1,100 watts per driver. Really I am rebuilding the two that i have, and adding two more for the final product, just adjusting the depth so the rear drivers don;t bang against the rear wall when they are running hard.


See above, but yes, polyfill will be used at least in mine. Not to make the drivers see a "larger" cabinet but to quell the resonant freq's of the box itself. I always use poly as well.




Not cone material but more the fact that the SubM if it was active, had a HPF setup on it where the dayton did not. I know you measured them equal but I would think the SI's with their extra displacement would be able to delve deeper than the dual 15's and that was what you actually were hearing. The additional displacement of the SI's even if the subM was passive would still account for this fact.
