Hello everyone,
i'm about to build a ported subwoofer and i need some advice in the driver selection.I'm between the dayton DCS385-4 and the DCS380-4.The dcs385 plotes a little bit better, but it's not in stock and it says that it's going to be at around 50 days.So do you see any other real difference those two drivers can have?
Right now i'm considering of buying the dcs380 , cause i would like not to wait that much.Do you think it's worth to wait to get the dcs385?
Also what mdf thickness do you recommend for the enclosure? i would like as uncolored sound as possible, weight is not an issue(120-130 litres internal volume).
Thank you very much!

I thought that Parts Express provides the suggested alignments.
For enclosure material thickness, look at the Dayton sub cabinets that PE offers.

The thickness of the pre-cut cabinets is 3/4" MDF...the front baffle, "double thick" at 1 1/2"....OK.
All their subs are sealed, & rather small in size.....no doubt a concession to the WAF.....At 41.66 & 43.87 worth of EBP....the two are virtually identical.
Since the EBP is right at that "one or the other"....point of sealed or ported....I would opt for the ported variety....get the simulation programs fired up & model a ported version. I have no doubt whatsoever you'll get some super-deep performance numbers, limited only by Xmax numbers vs. frequency....at the concession of enclosure size...they will model out really big...

For those who don't readily have access to sims...
The Dayton DCS380-4 sub...........
Sealed, cute little enclosure, but "only" -2.99Db @ 34.64 Hz...OK
Ported, serious sized at Appx. a tad over three feet, by two feet, by some thirty inches ....(355.6 Liters)....a very deep -3.07Db @ 18.61Hz.,
A port, 152mm (Six inch) diameter, 277mm (10 7/8")..long....
Just how much picture frame rattling power?...really only power & Xmax...

Both drivers get very deep but only with huge enclosures. Unfortunatly right now i'm limited to only 4cu.ft. due to room limitations. Both plot okay at such enclosures and with some dsp they are going to be perfect for me.
From what i heard, i think i'm going to go for the dcs380, since there's no big difference.
Thank you all!

Actually a was wrong, it's 5cu.ft. not 4.
That thing you showed is a beast and i bet it would have an f3 of something like 10hz. It would need a crane to be lifted and a specially built room, so not for me really😀

Wow....too big?...It IS just one of these, oh well...PS, just Yesterday I simmed up an enclosure of 97 cubic feet (2754.8L) ...I was juggling dimensions for a decent "footprint"....driver height in relation to the ear.....ceiling height & doorframe width.... a bit too big, my wife said a few minutes ago...

The notation F3 is a notation of frequency down, or minus Three decibels worth... a falling off in response if you will, on the bottom end.
The notation is commonly written, abbreviated, as I had in a previous post...as in..for the sealed version -2.99Db@34.64Hz....this "translates" out to Minus two point nine nine decibels at Thirty four point six four hertz.
The ported version bests that figure, -3.07 Db@18.61Hz.
By punch...what exactly does "punch" mean anyways? By applying these types of adjectives we have no way of knowing what your meaning is...same applies for such wording as "bright, warm, soft, articulate, harsh", etc.etc.

hey Rick, great input, btw what sim s/w are you using?
One thing to note if you are using active eq for the bottom end, a sealed box is still an option. I think it would be easier to compensate the gentle roll off of the sealed config vs the sharper ported design. I could be full of crap too 🙂
I still like my 15" woofer in a sealed 3cu ft heavy box. Now in generation 3 of upgrades to drivers and xover.
Good luck with your creation.

I use WinISD beta...it is somewhat basic, it doesn't have calculations for the likes of Xmax vs. frequency, among others, .....to find out when you run out of cone travel..as you go further & further down in frequency.
No, a seven foot high, six foot wide, four foot deep sized enclosure...uh huh, too big...it was for an 18" driver. Won't happen.
Yeah, of course one could EQ out any shortcomings....adding gear in the signal path invites artifacts you likely don't want.

5 ft^3 is technically much too small for either driver even if sealed, so vented alignment per se is out of the question unless you want a ~ 'one note' boombox or a way too small, power limiting port, leaving only ~aperiodic [heavily damped ~open back cab].
Anyway, based solely on its published specs, the 385 is only worth the wait if a really large cab is an option. Can you go tall or lay down long [like for behind the listening area, etc.] to get a big cab?
WRT to cab panel thickness, braced 18-19 mm no void [BB, appleply or marine grade] plywood is sufficient for subwoofers and to get a ~matching MOE [stiffness] requires at least 1.25" thick MDF.

Which EXACT version are you using ? If it's WinISD beta V 0.44 then i'm Not surprised as it's 14 years old 😀
The next versions onwards eg, WinISD Pro Alpha V0.50a7 Did/DOES calculate Xmax vs. frequency.
You should update WinISD to the latest version, which also DOES calculate Xmax vs. frequency etc etc 🙂 http://www.linearteam.org/download/winisd-07x.exe

I understand you, sorry for that. By saying "punch" I mean dynamicness, that ooomph from the kickdrum for example.
Finally I ended with a 5.3 cubic feet enclosure with an f3 of 30 Hz, I think.
I am going to power it with a Behringer NU1000DSP, which has the headroom to EQ a bit, for an f3 of around 26 Hz. Right now I am double-checking everything in order to order them in the next days.

Notice that boom/punch is in the mid-bass, so above a typical sub's bandwidth [BW]: Interactive Frequency Chart - Independent Recording Network

Thought that part of the punch was lower than the midbass, okay I'm not an expert so I'm not going doubt it.
As for the boombox you said, yes without EQ the FR looks like a boombox, but with 600 watts, the amp has plenty of headroom for some generous EQ.In addition the EQ needs to be applied around of the fb, so it's not going to affect Xmax much.
I have planned it quite a bit and so far it seems very satisfactory.

As my tag line strongly implies, I view this much EQ/power required as way too much added distortion, so will always recommend alternatives.
Regardless, good luck with it and hope it meets your expectations!

Thanks, of the three newest computers, one for each of the last three years...I dropped the first editions I found.....I guess i should have read more on the downloads...I thought the extended versions cost $$, oh well, time to start simming up some of my favorite drivers...trying to get them to perform.
