So does this mean that PartsExpress is becoming the new Walmart of the subwoofer world?

Don't know if I'd use the word superior, but certainly regarding displacement at least, I wouldn't forget about the fi ib3 series. Vas isn't that much larger, they work well in largish sealed enclosures (ie need not be limited only to ib), and in that environment power handling is plenty high.

I'm interested in the Dayton distortion numbers at similar displacement. This is nearly impossible info to gather though.

Man i didnt realize how close their (vas) ratings were but the relatively low BL number on the FI IB 18 concerns me in any reasonably small sealed alignment.

I havent modeled them so just thinking out loud but id think the enclosure resistance on a driver with that low a motor strength would bog it down?

Guess i should model and see but sometimes i like to dissect the T/S and discuss, then model and see where i'm wrong...... wink.gif

If you have the room for a big enclosure they model well. I agree about not forcing them into small enclosures. That requires high motor strength and all the baggage that entails.

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......

When you think about it the only competition at this price is low throw high sensitivity drivers. If you have $500 you cant go wrong with buying two of these and putting them in your two front corners.

If you have $1000 then buy two UXL-18s.

Interesting that the RSS460HO 18" models almost identical to the Titanic 15" in a 5 cubic foot box, Xmax at 20hz with 600 watts.
Cone area vs cone travel I guess. I wonder in real world testing and listening if in fact they would be indistiguishable.

How would a sealed 18" RSSHO compare to a ported 15" RSSHO?

I was all set to begin a 15" RSSHO in a 5.5 cubic foot box, with twin 28" long ports tuned to 20hz on the recommendation over at PE. I have a Mac and I don't know how to model a sub. So I'm just wondering if the 15" is still the way to go. I'm assuming distortion levels are similar.

Thanks
Dan

Thanks guys. So if I'm looking at these correctly, it looks like the 15" HO ported does better getting down to 20 hz and looks a little flatter. I'll stick with that then. Much appreciated!

Is this Dayton 18 inch sub better suited for a sealed enclosure or a ported enclosure? If sealed, what would be the optimal box size? Same question with regards to ported?
Also, concerning sealed vs ported, how much power would be needed for both sealed and ported?

Both work well with this one.

Sealed: 3-4cuft or more if one wishes

Vented: 6-9cuft

250-500w for either alignment

How do you think this 18" Dayton HO would sound in both a sealed and ported enclosure?

Lol. I have no idea, man. About the same that any driver would in either a sealed or vented enclosure. wink.gif

Just depends on your needs. Both alignments would work well.

8 MFW-15's in dual oppossed config or 4 of these in four sealed enclosures?

I recall someone equating one of these in output to a titanic 15, From memory two MFWs had a slight edge over a single titanic but required a larger box.  Assuming the aforementioned correct, I would think the MFWs would win on output, but distortion etc IDK.  BTW, The MFWs are NLA unless you have a lead on some......

I have eight of them and have planned to build 4 five cu ft boxes for them. Just checking options I guess.

if these things had double the Xmax, they would be killer. Parts Express would not be able to keep the shelves stocked.

Seriously

If somehow we could campaign the design to Dayton for the HF model to shoot for a 20-25mm Xmax.....

Someone should get 1 of these to Erin to get it Klippel tested. I'm suspicious it may have more xmax than rated. Then this thing would prove to be really good.

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

I think if Mark Seaton is close with his guess I think its a very capable driver.
I'm either going with 4 of the 390HF's or 4 of the these 18's.

As most here already know, I chose it for my first DIY build which I should have done within a week so I can provide some feedback.

As a guy who really only knows enough to be dangerous right now, I simply extrapolated the hurrahs that seem to be wide-spread for their other RS subs. It seemed reasonable for me to do so, given the anecdotal accounts re the aforementioned that are all over this forum and elsewhere.

Hopefully that 12-13 mm xmax will be exceeded as well as overall expectations.

again, for me, at $275 for the driver and cab, I fully expect to be more than satisfied.

Same here. Already have it planned to use four of them stacked in a cube, all sealed, as a rear subwoofer system.
