To directly compare retail costs (when originally purchased) of SVS Headphone only system, to Speaker only system, I'd like to compare exactly what costs I can compare to with my personal Speaker based Home Theater.
Keep in mind my SVS Realiser system sounds much better than my Speaker set up, so, I won't count the $200 spent on the Mi Casa calibration. Which is cheaper than any real room treatments for a speaker rig. (although mine's pretty ghetto). My real weakness other than the Room Treatment, are my Speakers.
Speaker Home Theater
NHT Super Zero Speakers $150 Each x5 = $750
Speaker Stands and Mounting equipment = $150
Velodyne HGS10 Subwoofer = $1800
Total = $2700
Smyth SVS Realiser "Stealth Home Theater"
Smyth SVS Realiser System = $3000
Crowson TES-100 Stereo Motion System = $599
Total = $3599
Please note that I am not counting "peripherals" such as Amps, PreAmp Processors, cables, wires, etc, as many of them are actually shared with each other.
If I were to have something that would be more equal comparison sound quality wise, I'd definitely have to up the speaker cost to at least $300 each and 7 speakers (because my Realiser PRIR is for a 7.1 set up) total for $2100 worth of Speakers
making the real comparable total = $4050 And I'm not including any extra cable, wire, stands / mounting equipment.
So, that's how I justified the math. Yes, it's not cheap. But a REAL speaker based home theater is anything but cheap, and is in fact more expensive.
So, do the math and it can very well be cost effective. And best part is it's easily transportable. How many people can carry an entire home theater in their carry on luggage?
