Actually this is an interesting subject. I'd like to learn more about how good self-assembled speakers can be. What are the components that go into it, and how do you ensure that they are of high quality?
I haven't actually heard the MX5021s, but from whatever I've read about them I know that those are the only ones that can interest me. A friend of mine bought FX5051s some days back, because he wanted a 5 channel gaming set. Those are not satisfactory to my ears. The sound is thin, no roundedness, and is generally dissatisfactory. The bass is good as it's tight and not boomy, but the midrange is poor. Moreover they start distorting just above 60%.
I'd have bought the MX5021s but I'm thinking that for 8K odd that they cost, if I add some more grands I should be a able to get a proper bookshelf music system. But one can't really say without hearing. The 5021s might turn out better than systems twice as expensive.
But the audio-equipment industry in India is just disgusting -- they simply want to focus on how loud and boomy the speakers can be, with little concern that the music is getting totally drowned by the overpowering beats. I couldn't find a single set with non-ported speakers in the market for the life of me.
sorry for going OT , but its good information i think everyone ought to have.
buying the drive units , then assembling the cabinets here seems cheaper to me than buying teh whole thing abroad. woofers from local brands like bolton/dainty and Phillips dome tweeters are available in electronics shops . they're quite VFM, and can beat any PC speaker setup when it comes to the sheer authority of the sound. for personal/near field listening at low ~ medium volumes , these PC systems are quite alright, but the assembled systems come into their own when you start cranking up the volume
my current setup was assembled when i was in college, lots of time and limited money (when people were off buying FX 5700's , i saved up to buy 8 inch woofers and dome tweeters). but now the sony Xplod sub turns out to be a limiting factor( its bass is quite inferior to the floorstanders i have
)
You can get high quality drivers like peerless, vifa etc in india, or if you can buy from abroad, practically anything
Crossover design, you'll have to take care of , because most neglect it. then the cabinet design, you can go overboard with it , because you dont have to worry about shipping, and it will cost much lesser for you to make it here . use 1 inch MDF and reinforce the heck out of it
The electronics, well, its a bit hard, but there are a lot of electronics stores which do make amplifier boards. they usually quote the power figures quite generously.. something which claims to be 40+40 W might turn out to be just 12+12 :| by looking at the supply voltage requirements , you should be able to judge the output. also, some allow DIY board (with components and a spare PCB or ready soldered boards.) if you know your way around electronics , you should be able to buy a good one if you have some fluency with DIY electronics !
you can do all this , or get an assembler, just like local PC assemblers to make you a speaker system by you quoting a config ( ie 8 inch bolton speakers , i inch dome tweeter, 60+ 60 W amp, no bass and treble controls ( they usually put it by default , and that is usually implemented with some suxxy op amps like the LM 324) so avoid them at all costs
, and wooden floorstanding ('tower') cabinets .
