I understand the mounting cutout is slightly different, but could someone tell me if the mounting holes pattern are the same as the Dayton Audio DVC385-88 15" DVC Series Subwoofer? They both have 8 mounting holes so would they line up with each other?
The bolt hole circle on the RS woofer is 368mm or 14.48" and the DVC385 is 369.8mm or 14.56".

I guess I'm having the same difficulty others have had and that is screw size. I tried a # 8 screw ans could not drill down because I was getting metal shavings. Anything less seems way to small. Help!
I would recommend either #10-32 or 1/4"-20 thread screws for this driver. We offer a cast frame driver mounting kit in both sizes.

I want to build a box for 2 of these with a crown dls 1500. I can go wide and tall . I want it sealed. what do you recommend for box detentions.
A pair of these require about 6 cubic feet for the overall volume. I would recommend a box with external dimensions of 45"H x 24"W x 12"D.

How will this driver perform in the 300-7078 sub box kit?
I have purchased 2 ea. of these subs and before I start to build enclosures I wanted to find out if the "Knock-Down MDF 3.0 ft³ Subwoofer Cabinet for Dayton Audio 15" Reference Series HO Subwoofer" should be a suitable cabinet.
This woofer performs very well in this enclosure with an F3 of 36 Hz and F10 of 20 Hz.

Good fit for a sealed 122L (4.63 ft3) down firing enclosure?
I may replace my old (and fried) Adire Audio Tempest 15" sub with this one. I built a 122L (4.63 ft3) sealed enclosure specifically for the Tempest sub with a Q of 0.707. It's also a down firing design. With that said, will this sub do well in this enclosure for music listening and occasional home theater listening?
That volume will work very well with this woofer.

Is this a good match for the Dayton Audio SA1000 amp?
To say the least, I have been very disappointed with my SA1000 sub amp from PE. As others have pointed out, the amp tends to clip very quickly and limits output to the sub at very low volumes. It's disappointing because it doesn't "feel" like a 1000W amp. My previous Dayton Audio 250W plate amp "sounded" louder. My disappointment turned to annoyance when the amp fried one of my voice coils in my Adire Audio Tempest 15" sub. In turn, it's time for a new 4 Ohm sub and this seems like a logical replacement. Can anyone tell me if this would be a good match for the SA1000? I will be using my existing 122L (4.63 ft3) sealed, down firing Q=0.707 enclosure. I will primarily be using it for music, with occasional home theater listening.
Yes this will work fine with that amplifier for either application.

Will this driver work in an infinite baffle design
I am looking to do a spare room IB set up with DA RSS390HF-4 15" speakers @4 any input would help. I know about the DA15" IB but was looking for a more robust driver. Thanks
Yes it will work for IB although the IB385 will provide more output with the same power and not require as much EQ on the bottom end. You will need some form of a high pass filter for either sub for protection.

Is there a metal grill made specificly for the RSS 390? The surround sticks up too far for standard protective grills...
how about the Goldwood bar-type grill? PE # BAR15/BLACK available in black or chrome. Has enough height for most subwoofers, but you can always use stand-offs or spacers to give it more height.

I have an 8.26 cu ft enclosure with two 4" ports tuned to 21hz. How would this driver function in this enclosure?
This woofer would be OK however you would benefit from a lower tuning frequency in this volume. Looks like your F3 is 20 Hz with this woofer as is which is not bad.

Will this enclosure work?
Would a pair of these work well in a setup like this? Each sub would be in it's own enclosure with 5.3ft^3, 4"x15" 55" port. They would be powered by a QSC RMX-850. This will mostly be for HT, with some music mixed in.
If you search for the WOOFER SELECTION GUIDE and find this driver - it will give you good starting points for sealed and ported versions of this driver. Porting extends bass much lower with the T/S specs of this driver - but for a port tuning of 21hz, you need a 9 cubic foot cabinet. When building a cabinet with a large port - split the port area into multiple tubes. JBL has done this over the years using 2 or 3 smaller tubes rather than one very large one. As for the QSC amp - the one you are choosing is under-powered. Options would be two of them in mono (ideal) or an RMX 2450.

300 vs 500 watt amp
If I put this in a ~4.5^3ft sealed cube with fiberglass insulation would a 300 watt amp be sufficient to power it, or would a 500 watt be better? What would be the volume(db) and frequency response difference between them? Or am I asking too specific of a question?
Assuming you have calculated the correct box size, etc, there will be a difference in performance between the 300 and 500 watt amp. It's like the engine in a car. You can get a BMW with a inline 6 or a turbo V8. One has more "head room". With the 500 watt amp, you will have a lot more dynamic headroom and it will perform better - especially on special effects for home theater. Don't expect dramatic increases in volume - but you will find the lower range much more controlled. As with any subwoofer - the more power - the more effortless the woofer will perform.

Dayton RSS390HF-4 15" with dual or single passive radiators?
I was thinking of using this driver a yung 300 watt amp and 2 css 15'' passive radiators in a 4.98 cubic foot box. is this a good design?
Passive Radiators are complex to make work correctly - especially in regard to phase cancellation. This subwoofer is excellent, and will perform best in a 9 cubic foot enclosure with the port tuned to an F3 of 21hz. 9 cubic feet may sound big - but it's just a tad larger than 2x2x2 internally, not including driver and port displacement. That will be the easiest for a project on a hobbyist level.Mark 26976 comments: "... which WinISD modeled as best for sealed cabinet Q... (WinISD is a software that helps compute this kind of design. Use it or similar.) Passive radiator designs not only eliminate port noise and allow for deeper extension in a smaller cabinet than ported or sealed designs, but also often deliver cleaner bass (when properly done) than ported designs due to quasi-sealed enclosure."

ported or sealed ?
i have a 5.5 cu ft. box dimensions are 19 3/4'' W 13 1/2 '' D 36 1/4'' H, would it be better sealed or ported with this sub ? i want good sQ and good spl im using a 252 watt dayton amp thanks in advance
Fs / Qes = 36.73 which says keep it sealed. Should perform well in 5.5ft^3.

Better choice for larger dedicated rooms
Which is better for SQ, Titanic 15" mk3 or RSS390HF. Prefer sealed enclosures. What about the Titanic 15" passive to add. Allready have a Titanic Mk3 15" sealed without passive.
Better is a matter of opinion and there is no right or wrong answer. I generally recommend the Titanics for home theater use and the Reference series for music. The Reference is designed to have less distortion which makes it a very clean sounding driver at lower frequencies.

I have an old AudioSource SW-15 sub and was wondering if this driver could be used in that enclosure. I'm thinking that I would need to block off the ports (2 - 3"x6") and stuff the box with polyfill. I've already replaced the internal wiring with 12ga OFC and added additional cross-bracing.
I'm not familiar with the SW-15. But the high qts of this speaker would indicate a sealed enclosure is definetly the way to go. A large cabinet of at least 2 cu ft would give the best low end response. I would also add some bracing.

I wanted to get 2 of these and put them in a sealed enclosure for my car. I'm trying to have a smallish size box. What size box would you recommend?
Going to be running both with a Jl 1000 1
I wouldn't go any smaller than 5 cu ft for two of these. The 3db down point is roughly 30hz this way so it should still sound pretty good.If you have more room you can definitely use it, but any smaller and the response starts getting ragged and sloped below about 50hz so you would lose a lot of what most people want in car audio sound.

What is the ideal sealed enclosure size for this driver with sound quality in mind?Further, what would be an acceptable compromise with how much fill?
Hi J168 Liters will be the minimun to get the best performance.The knee -3db will be arround 28 Hz and the spl will be arrond 114 dB.Make it well braced and sturdy. 1st quality Baltic Birch is my recomendation. Dont use MDF. Will come apart under his own vibration.will shake a lot.BestDavid

How much space is required between the pole vent and the back of the speaker enclosure?
With vents or ports, you want at least as much clearance as the diameter of the vent or port. For instance, with a 3" port, you'd want 3" clearance between the port and any interior surface. The same rule of thumb applies to the pole vents.

What would be a good amp match for this sub?
Just wondering what amp is recommended with this sub.
That depends on how you intend to use the speaker. Are you looking for a stand-alone powered sub for theater and/or home music use? or in a cabinet intended for live use. A great inexpensive built-in amp is model SA240-B ...a 240 watt module. I personally built my own sub with a 250 watt amp (@4ohms) that rocks the entire house.Stand-alone amps for subwoofers are also available.

Is this a good car audio sub?
The max volume is 10.5 cu ft that a trapiziodak box can fit in my car. I would like two of these but im not sure if i can get a great low end response with such a moderate box? I would get a 1600 watt amp to power them, also port distortion is a peav of mine. I allways put the biggest ports i can. They will probly be wired 2ohm mono. Im not look for sub sonic frequencies just something loud, low and distortion free as much as possible.
THIS DRIVER IS WELL SUITED FOR AUTO USE...IT GOES LOW BUT HAS VERY GOOD TONAL DEFINITION AND PLENTY OF PUNCH! JUST MAKE SURE THAT THE ENCLOSURE YOU USE IS THE RIGHT SIZE. IT CAN BE USED IN A SEALED OR PORTED ENCLOSURE. I WOULD SUGGEST A SEALED ENCLOSURE TO ENSURE MORE DEFINITION AND LESS BOOMINESS UNLESS YOU WANT TO REALLY WANT TO RATTLE YOUR WINDOWS LOOSE, THEN PORT THE ENCLOSURE.

What is the optimal ported tuning for a box around 5 to 6 cubic feet w/300 to 350 watts?
I've played around with winsid and have a 5ft cube w/2 4" 38" ports.
It looks good between 16 and 20 Hz, your tuning puts it right about 18 Hz. With 350 watts you reach your excursion limits at just under 15 Hz which may be low enough not to worry about a subsonic filter unless you really push your system.

Can this sub be used in a Pro Audio cabinet with a horn driver?
While it could be done, theoretically, I'd advise strongly against doing so. This driver is not built for the rigors of pro audio, and the frequency response does not extend high enough to really blend well with any horn driver of which I'm aware. I'd recommend going with a standard woofer that is designed for pro audio application.

Can these be mounted with screws, or only with T-Nuts?
If screws are possible, what size are recommended?
Screws can be used with this subwoofer (wood or machine type with T-Nuts). The screw hole diameter is 6.5 mm (0.256"). 1/4" shaft diameter screws (i.e. 1/4"-20, 1/4"-28) are recommended.
