Hey Folks,

NicksHitachi pointed out that the Dayton Audio DVC385-88 15" DVC Series Subwoofer is on sale right now for about 30% off for $99 w/ free shipping.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-190

This is a great deal for anyone who missed the buyout Erich did on the MFW's a while back and/or wanted to double up. :-)

I'm not sure how long they will be on sale.

Best,

John

Listen. It's All Good.

Definitely worth picking up. Low budget or not.

Hmmm... I've had an extra Adire 250w plate on me for nearly 10 years now, still fresh in it's box. Maybe it's time to do something with it. But what?

congrats joe, did you go for 16 or 32? :-)~

---

seriously, this is a great driver that works well with the behringer amps in a set of four.

a single driver wired in parallel gives 4 ohms and two wired in parallel gives 2 ohms.

hooked up to one channel of a ep4000 or inuke3000 provides about 1000 or so real watts per channel or 500 watts per driver, which is a good number for this driver in a 3-4 cubic foot enclosure.

so, breaking it down, for $99 for the driver, $100 for ~500 watts per 1/2 channel (or $125 if you get the amp with dsp which i recommend), and add enclosure either diy or erich's flat packs, i'm not sure there is a better deal going. one per corner would be great for most folks and two per corner is getting into insane territory.

Listen. It's All Good.

Gents... Ever since Ricci's test of the new HO 18", all Dayton subs have piqued my interest. With a published xmax of 12.75mm, the 18" turned out to be extremely underrated and was able to achieve about 20mm of travel before getting into trouble. I noticed this sub, nor the 15" RSS390HO have been tested at data-bass. I took the time to donate a few $ to data-bass and requested they add these to their test queue.

If the 18" HO test is any indication (i hope so) and these both test to be similarly underrated, this $99 deal turns from awesome to outright incredible!

I'm not the type to make assimptions, so I would rather see the objective data myself before making a purchase.

Man, imagine one dual opposed cabinet ($300) plus amp ($200) out performing a JL F113.

Another clear example of DIY Value!

^^^ I've got a pair of boxes that were meant to be for Polk MoMo 15" - before I realized they were junk. I ought to get a pair of these just for fun and stick them in those boxes. Going dual-opposed would only be a matter of taking a jigsaw to the back panel of those boxes. smile.gif

That would be an excellent option DK, I say go for it smile.gif For $200, you really can't go wrong there.

wouldn't even need to chop the backs off, just attach to each other. the benefit of the dual opposed is the opposing mechanical forces not the air inside.

"the 18" turned out to be extremely underrated and was able to achieve about 20mm of travel before getting into trouble."

on that driver, the usable excursion was about 20mm, with xmech (the trouble point) being up around 30mm.

don't expect that from this driver. this one probably has usable excursion in the upper teens.

So maybe slightly over it's 15mm rating?

Do you anticipate the same for the HO variant at about $50 more?

yeah, i'm conservatively guessing 18-19, though it could be more.

as for the 15" ho, i don't know and i don't want to wild ass guess that one.

How do i get on the list for your flat packs?

ported yes, 6 ft^3 is about right. sealed alignment you can get away with much less.

My guess is that the xmech where the coil hits the back plate on these is right about 25mm or slightly less. Also the surround is much smaller so probably less linear at high excursion. The Ho has less coil length and 2mm less xmax but should have 2mm more xmech so maybe 27mm for it.

What should I expect of this 3 cu ft flat pack and the DVC-385?

For example:
How much power would it need? 500 W?
How low in the frequency range would it go?

I know it's being used with LilMike's F20 with as little as 300 W and down to 20 Hz

The price is great and surely won't last.

"What should I expect of this 3 cu ft flat pack and the DVC-385?"

typical sealed box rolloff, -3db point around 37hz before room effects and eq.

"How much power would it need? 500 W?"

that would be good per driver.

"How low in the frequency range would it go?"

that depends on how you eq it, your room, and how loud you wish to play it.

"I know it's being used with LilMike's F20 with as little as 300 W and down to 20 Hz"

that is a good enclosure, but a hair larger than 3 cubic feet sealed. :-)

So this driver is rated 8ohm impedance. Am I better off spending a little more and getting a woofer that is 4ohm rated since most amps will push much more power into 4ohms?

The RSS-390 HO is rated 4ohm impedance and the Titanic MKIII is on a good sale too.

it has dual 8 ohm coils. they can be wired in parallel for 4 ohms net or in series for 16 ohms net.

a single driver wired in parallel gives 4 ohms and two wired in parallel gives 2 ohms.
hooked up to one channel of a ep4000 or inuke3000 provides about 1000 or so real watts per channel or 500 watts per driver, which is a good number for this driver in a 3-4 cubic foot enclosure.
so, breaking it down, for $99 for the driver, $100 for ~500 watts per 1/2 channel (or $125 if you get the amp with dsp which i recommend), and add enclosure either diy or erich's flat packs, i'm not sure there is a better deal going. one per corner would be great for most folks and two per corner is getting into insane territory.

Or!

8 DVC385-88 15" Drivers = $800
1 iNuke6000DSP AMP = $500
Construction Materials = $200

So $1,500 plus ones time and effort = Incredible dynamic capability!

Build two quad opposed cabinets, each wired at a 4 ohm load and one cabinet to each channel of the iNuke.

Hell, you can buy 9 of these driers for less that what I paid for a single LMS-U. Guess it all comes down to your space available.

18-19mm sounds good enough at this price point.

Man, I have no use for one (or more) of these but the urge to buy is soooo strong. I'm trying to justify buying a few but I'm actually having trouble figuring out what to do with them!

This is a great deal. If I had room for another F20 in the LR I'd do it but I don't. I have no room in the truck... Maybe a THT for the garage? Or one for my son's room...

I just don't think I can pass it up. Anyone else having this dilemma?

I built a thtlp for Burning Man (outdoor festival) and I also use it for ht at home. I love it and it works well for both, but I think a titan may be a better choice for outdoor use. The tradeoff is extension (tht) vs output (titan).
