If you are using multiple amplifiers (and if you are going to have a sub you will need to) these amplifiers need to be hooked up in a way that each gets the input signal.
Having said all this, those Swans you are looking at already have an amplifier built into them. This means there would be no way (easily) for these speakers to communicate to the subwoofer what sound to play. Instead of looking for powered speakers, you need to look for speakers, a mini amp, a subwoofer amp (plate amp) and a subwoofer.
If you want a basic inexpensive system here is what some people have done in the past. They use a basic Lepai amp
. Make sure it comes with the power supply, not all do. A subwoofer plate amp
and a subwoofer. Most people on this site swear by the infinity 1262
. There's also a lot of build on here for some great sounding boxes. Then get a pair of non-powered bookshelf speakers.
The reason you want something like the Dayton amplifier vs some of the other plate amplifiers, is it has speaker wire in and out. A typical subwoofer for home application uses RCA's to hook it up. In most applications you would use a special preout on your amplifier to hook the sub up. Most inexpensive amps do not have this output. So instead, you run speaker wire from the Lepai amp, into the Dayton subwoofer amp, then out of the Dayton Subwoofer amp, into the bookshelf speakers. You now have everything hooked up perfectly. The only problem is I do not know if they carry those parts in India. If not, that is the basics of what you would be looking for.
Thanks for the links man! You've been very helpful
I checked out all the parts you suggested... and wow those infinity 1262 subs are really powerful for the price and popular too. I may have to reconsider my decision for going with the Sony xplod sub! Oh, so a powered speaker cannot be hooked up to my setup.... have to start looking for passive speakers then... please suggest any good passive speakers with enclosures built in. If I go for infinity sub, then I have to buy the sub enclosure separately .. and I don't want to buy another enclosure just for the bookshelf speakers! btw, that Lepai amp you suggested is available here in India but it doesn't come with power supply! (there you go). I have to hunt for other amplifiers.
I have these under my consideration btw:
also this one:
it's sick how much power this one packs in for the lower price!
500W x 4 Output at 4 Ohms
1000W x 2 bridged Output at 2 Ohms!
I guess all these amps don't come with power supply and I have to find a way to power them using external power source right?
I doubt it's overkill for Infinity 12" sub having a 300W RMS rating (continuous)
Interestingly, I found sonicelectronix selling a pair of Infinity 12" subs along with nice ported enclosures built in here:
they suggest 200 - 600 watts RMS @ 2 ohms operation for this beast.
Should I go for a single 12" sub (with enclosure having to buy separately) or a pair of two 12" Infinity subs with built in ported enclosures?
I also prefer ready to hook up speaker parts rather than trying to drill my way into making a sub work inside a third party separately purchased box! I am sceptical of assembling speakers at construction level as I am not a speaker expert but a Computer engineer
Also, I will be using my speaker setup for my personal room not the main hall. So, my room isn't that big. It's the size of a usual bed room.
summery of my current considerations:
1) subwoofer: Infinity 12" single/dual sub
2) Amp: Alpine MRV-M250 Mono subwoofer amplifier - 250 watts RMS x 1 at 2 ohms (for single sub)
Lanzar VCT4110 2,000-Watt 4-Channel High-Power Mosfet Amplifier (for dual subs with enclosures)
3) power source for the amp: STILL UNSURE
4) passive bookshelf speakers: STILL UNSURE
