Question What do you think about this 15" sub vs VBSS/Marty etc

I'm looking into building my first DIY sub. I like the VBSS for the price point, and the Marty for the geek factor, but I think it's too much money. I have a new home theatre room that's Dedicated to 50% movies and 50% Xbox not really any TV. I'm looking to "Feel the boom" in movies and increase that immersion experience. I'm purchasing my 120" screen and projector here soon. I have a friend who is a home theatre guru and he suggested this speaker.

Dayton Audio 15" Classic Subwoofer for $90

He mentioned that unlike the VBSS this doesn't need DSP to tune correctly and is a true sub with flat response curves. He thinks I can build 2 of them (1 ported and 1 sealed) to get both sides of the spectrum if I want. I think I'd want to go with ported first to hit the 20htz movie range.

Is he on the right track here? He mentioned this also affords a more normal amp and levels and crossover can be set on my X1400H receiver just fine. I'm pairing this sub with my 5 piece Elac debut 2.0 B6.2 and C6.2 setup (LRC&Surrounds). No sub yet hence the build.

Thoughts and comments?

Bonus question is an amp suggestion that I can expand later to add bass shakers.

No offense, but your friend seems to know just enough to be dangerous. I would not follow his advice.

It’ll work ok but the vbss driver is about the same money and you’d likely want dsp to tune your response to your room anyway. I’d go vbss over this all day long. Plus you’ll want dsp in the future for integrating shakers too.

I'm sure your friend has good intentions, but the tried and tested advice on a thread like the VBSS thread is too good to stray from. Someone suggesting to not use DSP and then mix sealed and ported with the same driver in the same room just does not bode well. If you were to mix the two types of sub enclosures, DSP would be the only way to get them to even come close to working. Even then, it would work better if you simply didn't mix the two types of boxes.

The inuke 3000 can, could put up to 4 VBSS subs on one channel then the bass shakers on the other.

The VBSS is a very capable system as designed. Four in a moderately sized room would be pretty potent.

something that you may like is a pa460 in a 6-7 cubic foot cab tuned to the mid 20's.
the yung plate amp with 500w and 6db of boost will provide a pretty flat response to the mid twenties and extension to the low 20's.
one plate amp could run two subs because the drivers are nominal 8 ohm.

the plate amp is on sale right now too.

Listen. It's All Good.

frequency response no eq. pa460 is red. classic 15" is black. 1w1m.



frequency response including eq in the plate amp.



the pa460 driver will have more max output across its entire operating range as well.

This was extremely helpful to see. Thank you for that. That makes a lot more sense to SEE it.
