New HT subwoofer. Dayton Ref 18"

[m R g S r]

I'm tempted to try this bad boy out!
Any experience here with it?

Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm 295-472

I have the 15" HO in my car, and enjoy it.

I think this sub would be nice with a lot of power for Home Theater (I have a THX approved QSC mx1500a for sub power)
The price is right as well. I may sell my current JL audio 12w3v3's in order to do a large sealed box in its place with EQ with this driver.

For now a horn is out of the question, I've moved into a small apartment and space is very limited. Next year ill have my own house / dedicated theater room for large horns. So until then....

Btw space available is 16"H x 30" W x 24" D. So a low tuned horn will not fit there.
This is strictly for home theater. Only music which will be played through it will be from movie sound tracks.
Control provided via marantz sr5006 receiver. Audyssey for auto setup, but can also do manual EQ / delay etc.

Ive dealt with the 10"s and 12"s (10" HF in my old car, used all others in various installs for home use). Those subs are solid and very hard to beat for the money. Always kept me satisfied... curious how the 18" turns out. Hope you pick one up and share the experience! 😉

Does it have the shorting rings like its little brothers?

 

[m R g S r]

It says triple shorting ring motor...so I'm assuming it does and it's not a typo!

Hi,

Make a closed box.. If the enclosure must be Ported:This driver requires a refrigerator size of volume in order to keep Port issues at a benign level.

Thanks B! That's only 44 volts to reach Xmax. My amp provides way more than that into 4 ohms. But I can just dial it back a lot.

Will be Low Passed at 80hz so group delay appears acceptable.

 

[bjorno]

..That's only 27 volts to reach Xmax..

..Will be Low Passed at 80hz so group delay appears acceptable..

Yes, a low tuning eats cone displacement capability... The IR peak at ~50 Hz disappears as soon as stuffing is introduced. No EQ/Signal-delay for the Mains is needed for either of the suggestions but a HPF/LPF is mandatory ,of course.

I read the wrong one. I meant 44 volts to Xmax.

I don't have high pass capability right now, but I rarely listen to it at levels which would bring it to high drive voltages.

I will introduce a mini DSP for high pads when I construct the subwoofer because I know it's necessary / will save the driver!

 

[m R g S r]

Okay mini DSP on the way. Gotta sell the old subs then ill get the new one! (Told myself I wouldn't order any new audio stuff until I sell older stuff lol)

Did a BR simulation to compare to the Monacor SPH-450TC (which IS available to me)
Pitty, the Dayton is nowhere to be found on this side of the earth. 🙁

I think you can't go wrong with this puppy...

 

[m R g S r]

Have you contacted parts express about shipping to you?

 

[ßart West-VL.]

Some time ago I just went ahead and put something in the shopping cart until I got to the checkout. There I could see the shipping cost... phew
And what if I have to send it back for warranty? etc....

I did this again, just now, I got this:
Error-FedEx: Rates are not available at this time.
So, I'll get back with this, thanks for pointing me to PE

O yes, Could be taxed at the border too... (that's another 30% or so)

 

[m R g S r]

Yeah that could kill the value aspect of the subwoofer for you that I am excited about 🙁

Looks like the minimum size box (sealed and QTC=0.8) is about 6 cubic feet with an f3 of 29hz. However, a Titanic 15 in the same size box with SBB4 vent tuning is fairly flat in the passband with an f3 of 23hz. I think the Titanic is still the best buy out there. That said, I must confess that I built a pair of 18" three way prosound speakers that I occasionally crank up and enjoy the hell out of.

 

[m R g S r]

Edit:

Space available is 22" Deep, 23" High, 33.5" Wide. That's external size. Which leaves about 8 Cubic Feet internal volume after a few braces. Not including driver displacement. (Roughly 225 Liters)

 

[ßart West-VL.]

In a BR, you're stuck at 20hz tuning with 225l (if you want a nice looking curve)
f3@21hz
f6@18hz
f10@15,5hz

This driver would cost me an additional $207.12 for shipping...
Already ordered other drivers from Germany, 2x Monacor SPH-450TC (shipping was €14.90 😉)

Good luck with your build, I'll follow this thread...
