Dayton Audio RSS460HO-4 in VBSS cab?

Hi all, I have a VBSS type build with the typical Dayton PA460-8 in it, powered by a Dayton Audio SPA500DSP. The cab is 35 x 21.5 x 21.5, and tuned to 20hz. The box calculator I used says its 7.66 ft3, with a net internal volume of 6.66 ft3. The PA speaker is 8ohm so I'm only using 250ish watts to push it right now. What would putting a Dayton Audio RSS460HO-4 in it do for me?

Right now I only have the one sub but Im also building a 12" or 15" sub for the front of the room. This new sub will only have a 250watt plate amp but it can also be ported and fairly large if I need it to be. Not quite as big as the VBSS* Room is 15x16x8ish.


Thank you!

In a straight model (no filters) you would lose 4 - 5dB from ~35Hz and up, but gain 2 - 3dB from 35 to ~18Hz replacing the PA460 with the RSS460HO. That is assuming 250w into the PA currently, and 400w into the RSS460.

Wouldn't know where port velocity/1st port resonance hits without port dimensions. Obviously the RSS has more xmax, but a HPF would still be needed as well.

Wow thank you. Makes me wonder if it would even be worth the cost. The smaller 12" or 15" could help fill in the loss at 35 and up.
Why 400w and not 500w into the RSS460? Are the 500DSP amps under powered? Right now I have my DSP set to PEQ:1 - 20Hz 6dB Q=0.7, 2 - 20Hz 6dB Q=0.6, 3 - 15hz 6dB Q=1.0 per mtg90's recommendations. My port is 1.5" x 20" and about 22-23" long!

Thank you for the help!

You'd be better off building another VBSS to help smooth the room modes, and adds (up to) 6db.

If space is an issue you could look into dual-opposed ported, but that would likely require a new box and turning the existing one into firewood.

Haha well I definitely cant put another VBSS sized sub in my living room. My thought was I would put that RSS460 in the VBSS build for more lower end and then a smaller 15" or 12" for the mid bass in the front of the room and to help smooth things out. But maybe it wouldn't be worth it.

If you are space bound I strongly encourage putting the most sub you can afford in the space. Increasing cone area through more sub woofers is a great thing, better than chasing after power handling and excursion, but that strategy is not always practical. Since you are in a spot where there is not room for more sub woofers, chasing the power and excursion thing might keep you from wanting an upgrade sooner. Otherwise you might find yourself looking to upgrade much sooner than you anticipated and you have nowhere to go with the first sub to gain more output in the living room

You can always turn it down, but you can only turn it up so much (before you run out of power, excursion or structural integrity).

What do you mean? There is room for another sub, just not as big as the VBSS! Its a monster.... well maybe not to you guys but sitting in my small house and compared to my old 12" its a monster

Not super popular, because of the price and the 21DS115 only being around $100 more, the 18DS115 offers a lot of output in something the size of a Marty Cube. This is about as much as you can get out of a small form factor. Rounding the port corners off might help a little bit, but this is pushing it

2200 watts into 4 Ohms is what is listed on the iNuke 6000DSP at PE, the NX6000D is pretty much a new front bumper and a coat of paint on the old 6000.

If you really want to upgrade, I would suggest saving until you really cannot go deeper down the rabbit hole without doing something to the house, like adding an addition or moving

The nuke is closer to 1500w above 30hz.
