Default New HT subwoofer. Dayton Ref 18"

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!

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.

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.
