I must agree with TV. I would take a pair of Velodyne HGS-18 subs ANY day of the week. I cross mine with my Nautilus 802 speakers at 55 Hz fourth order using the Meridian 861. I can guarantee you will be happy with a pair of HGS-18 subs. What are your main speakers? I have to admit that I wouldn't run ANY subwoofer higher than 80 Hz. The velodyne will sound just as good if croosed at 55 Hz as 80 Hz. Although obviously, it is nice to be able to use lower crossover settings around 50 or 60 Hz if your main speakers will allow it. I would absolutely love to hear the difference between a pair of HGS-18 subs vs a single Aerial SW. The truth is, I don't think I would trade two HGS-18's for two Aerial subwoofers for the reason that TV mentioned.
Subwoofers operate in cuch a limited bandwith that 'expensive' "high-quality" amps are not required. They require dependable, efficient high-power, high-current amps, that's all. that's what Velodyne uses--decent 'switching' amps. I would hope that for the higher price of the Aerial subs that they use some higher quality components in their amp, but for subwoofers, it is a waste of money IMO. The bottom line for a subwoofer is how it sounds and how it measures.
As far as both HGS-18 subs in the same corner vs one in each corner, that is a tough one that deserves a trial run in each configuration.
I would lean toward one in each corner simply because the LFE channel often contains a decent amount of 80-120 Hz information unfortunately.
IMO, when you have one in each corner it makes the sub less 'locatable' in general. I chose to use 2 HGS-18 subs in each corner, for 4 total. I'm still waiting on 2 more HGS-18 subs, they should be here within 2 weeks. Calibrating 4 is not easy...
The nice part is that I will have headroom galore and can trun the gains way down. You'd be suprized how easy it is to use up headroom when you play a disc with 10 Hz Sound effects on it. P.S. the electrician is coming by this week to install 2 more lines https://www.avsforum.com/ubb/smile.gif
I'd look into DIY subs as the next step up from multiple HGS-18 subs..
That is my current thinking. I just can't handle that task right now.
