NEW SUB FROM PARTS EXPRESS DAYTON 18 HO"

COOL. I wonder if an HF variant will follow? Too bad about keeping the same xmax, though (I'm guessing the same motor?). For a $250 sub, it seems lacking compared to others similar in price.

F**K YES!!! Thank you Dayton and PE!

Now make the HF version.

*scrambles to Unibox*

The price is right, it cosmetically looks great and the triple shorting ring should mean that the top end is clean and efficient. Xmax rating isn't much at 13mm but it may be an over achiever in that dept. like the rest of the RS/RF line. Judging from the pics the suspension is certainly capable of more. A relatively clean 20mm may not be out of the question. Maybe they will do a HF version with more xmax. I wish they would post the coil wind height and gap dimensions so we could atleast see what the geometric xmax is. One of these might have to end up on the DB test bench at some point.

Actually lower xmax.. kinda disappointing. Maybe theyre conservative about their xmax ratings. just has to beat the xmax ratings of pro woofers near that price

I was really hoping you'd come in and post your thoughts on this Josh. I know I promised you some 15hf's in the past but this might be the one I'll have to send you or throw in on. I'd really like your take on it.


20mm would make this thing so super awesome as it would easily add an additonal 3dB of output across the board but yeah, I'm hoping like what Josh said that it is a bit underrated but I won't hold my breath. I will however for a possible HF model though.

I've been hoping for an 18" version of these since they came out.

13mm xmax for an 18" is good if it's a Pro sub, home theater sub your probably better off getting the Titanic 15" with 20.5mm xmax and saving $50.

This guy sims well in multiples. Four of them in about 3.25cuft with 400w each model within a 1dB of my proposed dual RLp18 (4cuft and 2,200w per driver) system. Imho, that's pretty awesome! These would be great for someone who doesn't want to use a lot of super expensive amps and has room for the total system size which really isn't that large anyway. A single ep4k could make four of these keep up with one of my dual-opposed high power monsters.

At a glance, yeah, these seem kind of underwhelming but.... I like em.

Just don't look at them in singles. Multiples is the key with these guys. Are there more affordable choices? Of course. Total displacement isn't everything about a subwoofer system though, imo. It's just a really important part.


EDIT: Here. I made a comparison of four of these new guys from Dayton and compared the four of them to a single LMS-Ultra as the price for four is roughly as much as a single LMS-U. Now...obviously the LMS-U is the superior driver and blah blah blah. I would not say that these are better drivers than it. However, if one can fit the space and just wants to use a single and simple ep4k... the choice looks obvious to me.

So you order 8 of them yet?? Come on man, dont fight the feeling. You know youre gonna do it.

The pictures suggest it's a 3" VC variant of the 10/12/15" versions. I suspect it's the same ~0.375-0.4375" thick top/back plates and the Xmax is probably the geometric overhang. I'd bet 15mm is a safe guess for lower distortion, and probably 20+ for audibly good/acceptable range.

Again, a shame as it's sooo close to being something quite impressive vs. just pretty nice.

Stereo Integrity is getting into HT subs, their 18" has 20 mm Xmax, much better performance compared to the Dayton 18.

I don't order 8 of "everything" sheesh, your making me sound nuts

Well said

I have been out of the DIY building for a bit but wouldn't an eD 19Ov.2 be a better buy? Are they still around? Their website isn't up anymore. From what I recall its around the same price with a little more than twice the Xmax.

Well then I will!


Yeah, agreed. This would be a pretty good stand out driver had it had more throw I think and definitely would compete with the new Stereo Integrity 18" that is coming out sometime in the next century.


....aanndd pretty much this. However, this is the current leader in displacement for the dollar now, I believe. Except.... it doesn't exsist. *sigh* I hate that but the pre-order on these starts next week but the owner says it could be 100 days until he gets them. There is no saying that one could end up waiting forever for these like all the poor guys who got in on the AE group buy. The Dayton's are available now. With fastest shipping possible someone here could have a finished product next week. This doesn't mean much to some people but it is something to think about. Also, the Reference series in general have SUPER low distortion and inductance traits which we know nothing about wrt the SI 15's/18's.

All that being said, I've simmed the SI's and I wouldn't mind having them either.

eD is no longer in business.

"Stereo Integrity is getting into HT subs, their 18" has 20 mm Xmax, much better performance compared to the Dayton 18."

they look reasonably good and very reasonably priced, and there is a dearth of xbl drivers, BUT...none of them can be ordered.

"I wish they would post the coil wind height and gap dimensions so we could atleast see what the geometric xmax is."

looks like 10mm is the top plate in the pdf. also, the pdf has different specs for qes/qts than the sales page. i'd guess a 30mm hc, but that is just a w.a.g.

"Again, a shame as it's sooo close to being something quite impressive vs. just pretty nice."

yeah, they seem to have kind of figured out the inductance piece and the frequency response suggests no nastiness/resonances anywhere near the bass region (even though i have no idea what "under 200hz is not representative" means in a frequency response plot of a subwoofer). if the suspension is there, why not just a little more coil?

YES!

Good point. I've been waiting 2 years for the CSS SDX15 MKII. Believe it when you see I guess.

Made another sim that includes the SI 18's in the exact same size enclosure (trying to keep it apples to apples) and same power and another with more power than it could be powered at with it's extra throw.

Oh ... just a simple fyi for you guys, a ~95liter box is equivalent to a 20" cube using 3/4" stock.

Sensitivity is way short of pro woofers.

Didn't know about the SI HT woofers when i ordered the obsidian 18's, not that it matters much since they will be IBed, oh well.

Going from the build quality on the obsidians, those SI's will be an amazing value. Also i know Nick had mentioned sending samples to Ricci for testing. Would love to see the results of both the Obsidian and the SI.

Somebody has one.

Ouch. Nearly 1mH/ohm! Repurposed car audio motor for "HT use"?

Whoa, when did this happen? I spend very little time on this form in comparison to what i used to, so this is all news to me.
*edit* Google search provided the answer. Mismanagement.

That's right. Okay, so one dude on the internet named baniels has one but that's it til sometime in 2013.

That sucks. I liked them as a company. One that was always trying to put out new products at decent prices like that doesn't come along often. I guess there is a reason.

Indeed this occurred. I have an Obsidian 18 sitting on a workbench in my garage. The SI HT driver will be sent later.

Awesome looking forward to it.

I have to say I'm impressed by your ability to visually dissect a driver's internal structure from a few pictures. You must do this for a living.

Maybe a titanic version will follow......  who knows.

 

xmax is underwhelming indeed as smarter dudes have stated but who sells a superior 18 with that low of a Fs for $250 I don't know of any......
