Small or large sub for music

Have you tried daisy chaining all four?

Sorry for being so brief. I meant to say daisy chaining the four powered HGS subs via the Dayton's EQd line level (RCA) connection using each subs 1000 / 1250w amplifiers. 

I'm not sure of the ohm rating of the two HGS drivers. I'm assuming if they're anything below 8 ohms you may have presented the Dayton amplifier with a less than its combined 4 ohm minimum load which could affect the subs performance and possibly damage the drivers.

Blue Jeans or MonoPrice cable offer reasonably priced custom lengths of RCA cable.

Yeah, my daisy chain remark was directed to the original poster dbphd but I failed to make that point in both of my posts. 
I then confused your use of the Dayton Sub amplifier and High level conectivity with dbphd's HGS subs.

In the word of Rosan Rosanna Danna, "Never mind"!

When I did a half baked subwoofer comparison between my Velodyne DD-18 with two other sub owners of a REL Studio III and a JL Audio Fathom F113 (v1) using the JL Audio ARO there was a slight but audible peak just below the main speakers crossover point.

This was clearly visible using the Velodyne Room Optimization program. I was able to dial some of it out using the F113s LP freq. (Hz) dial. Bypassing ARO and using the Velodyne Manual Optimization I was not only able to clean up the crossover point make some Q adjustments and cut and boost a few other places to really smooth out its response and improve the F113s overall performance.

I understand JL Audio has made improvements with their v2 and is also marketing an ancillary companion crossover component. Regardless, the JL Audio is a very fine system that provided nearly the same girth of output of the DD-18 that seriously belies its 13" drivers size.

Some people and rappers don’t care about sound quality. Low-Fi is fine for them. For the rest of us, subwoofers only belong in the home theatre.

You know I always thought that Wilson, Magico, and Vandersteen were Low-Fi with their subwoofers blasting along with their statement products at audio shows.

Thanks for clearing that up.

Finally, I think DSP is a great idea when placement and room treatments have not worked. I see the three all working together as a system.

Proper positioning of my subwoofers and their onboard customizable Room Optimization has always improved their performance. I've never been satisfied with low frequency room treatments. A mater of taste and probably just lucky with my last three rooms.
