This can be answered by David Gage or any customer of his. Do you notice any boomy-ness when you play bassy movies like Mad Max Fury Road or Transformers? If so, does having more than 1 subwoofer reduce/eliminate any boomy-ness? Does the powerful bass easily overwhelm and drown out the other frequencies if you're not careful with the gain, or throw off your bass-to-treble ratio/proportion? Granted, I understand that most DSS customers enjoy bass and have more demands/standards for bass than most other audiophiles. Your thoughts or comments?
Also, what kind of circuits is everyone using? I notice these sub amplifiers can max out a continuous 4,000 watts. Anyone using a 30A 240V circuit or anything like that to host these subs? Multiple circuits? Obviously, most people won't ever use all that power for that long a period, but I was curious.
Thanks for the kind words. I'd rather my customers respond on the sound quality and they have so now I can weigh in. My taste in bass was defined over 25 years ago when I installed car stereos while in high school. While I installed sub systems of all kinds including quad 15" ported monsters taking up an entire hatchback, my truck had a single Boston Acoustic Pro 10" sealed sub. I had plenty of output but the ultimate goal was tight, clean bass and that hasn't changed.
Many people new to large 18" and especially the 24" sub think they are too large to be fast and articulate. Sorry to disappoint the uninitiated but physics is on our side, an 80 lb motor-magnet has no problems moving a 1+ lb cone and making it move wherever it wants, whenever it wants.
I started this company due to the 24" as I was one of those surprised by how clean, accurate, and effortless it was and even more so when I found out the sub was crossed at 100Hz. When I was at THE Newport Show in LA a couple years ago, I crossed the Mariana 24 at 120Hz just to show what it was capable of. I should point out the 18" shares many parts with the 24" including the magnet-motor so it of course is strong, powerful, clean, and tight as well.
Now, one other thing that surprises many people is how much the room truly affects a speaker and sub system. You could have the most expensive/best speakers in an untreated room and an inexpensive set of speakers in a treated room and I'd be pretty confident the speakers in the treated room would sound better. So some of the boomyness you might be referring to could be due to the room, especially with a single subwoofer. I am a huge fan of multiple subwoofers as the more subwoofers you have, the more even the bass will be in a room, up to 4 subs as beyond that there is a diminishing return. I have exchanged Mariana 24s from two customers for a pair of Mariana 18s (each) so the bass is more even as well as the fact that they weren't using the full capabilities of the single 24. But the primary reason they both wanted to exchange was for more even bass in the room provided by multiple subwoofers.
So if the Mariana 24 has too much output, why go for it? I've measured it in many rooms and the 24s are flat to about 7 Hz in those rooms, in one case it was flat down to 6 Hz. So the reason for the 24 is for those that want deep bass to be able to reproduce anything in a movie and yes there is material down below 10 Hz though not in all movies. But you will find sub-10 Hz content in all types of movies from of course action movies to animated movies and everything in between. Another reason to go with larger subs is effortless, clean bass. If you're not having to push a subwoofer hard, there won't be any distortion and you'll get much cleaner bass than pushing a smaller sub some. And I should point out that a pair of Mariana 18s is almost equal to a single Mariana 24 and if someone is trying to decide between the two, I will push towards multiple subs.
Regarding the amps, I have run a rack-mount SP2-8000 on a shared 20A circuit without issue so you can generally run a pair of the SP1-4000 amps on a single 120V 20A circuit without issue though I wouldn't have a bunch of other stuff on the same circuit. A 20A circuit can pull more amperage in short bursts plus you have to realize the SpeakerPower amps were designed specifically for subs and are over 95% efficient. So you can't exactly do the 4,000w calculations against 20A in terms of power but realize that it is a true continuous 4,000w and has been tested to have more long-term power output than any other amp that I know of. Again, part of that is the amp is a purpose-built subwoofer amp while most other amps are full range. Now Snowmanick and Aareses both have quad Mariana 18S systems with the SpeakerPower SP2-12000 240V amplifier, which saves some money by using 2 amp channels but still providing 3,000w per sub. This is likely my highest performing, yet bang for the buck system as you get 4 subwoofers, great power, yet not spend as much for 4 amplifiers. The only issue with sharing subwoofer channels is you will have to equally position each pair of subs equi-distant to the listening position such as in the corners or left/right of the center and similar in back.
Thanks for your interest, I hope that answered your questions effectively, along with feedback from owners living with their subs. Thanks guys!
