Frugal 2:1 system for compact space

zman01 · 19th March 2011, 01:35 PM

I have an uncle who's been asking me to improve his "TV/movie expereince". The gentleman will be 70+ years and his hearing is still pretty good. He's not satisfied with the sound reproduction from the TV (Samsung Series 5 LED) - he wants more clarity in dialogue and bit more oomph at the bottom end. His main use will be watching documentaries, TV shows, and movies.

His space is compact 7' x 7' - but opens into larger spaces on one side. I've thought of small 2.1 PC speaker systems but I find they sound mostly horrible for most stuff.

Anything interesting I can do with low cost FR drivers? Off the top of my head I was thinking something like the Needles mated with a small sub (if such a thing is possible)... for amplifier, will probably use a small chip amp.

How about Fostex FE103En, together with a side firing Peerless woofer in a slim floorstander?
I guess this woofer will do the job pretty well, 2nd order crossover at 250Hz-300Hz will do.

By taking room lift into account, I suspect sealed cabinet will do. The speakers should be pretty usable down to 40Hz. I can already picture a pair of tight and extended range speakers with slim cabinets.

Borispm,

Sounds interesting... any ideas on the cabinet? Something like Tysen?

Something like that...
If high efficiency is not a must, I suspect the Tangband speakers will be even better than the Fostex. At least they are better built.
I wanna try the bamboo cone 3" and 4", as well as the titanium ones. Those flat diaphragm full range should be excellent for off axis but they are not really cheap... Think about $50USD per driver...

Alright, back to the cabinets. Something around 20L is good enough for the woofer. The volume needed for the full range driver is pretty little indeed, something like 2L will be good enough.

High efficiency is not a must, even high fidelity is not a must

Still have to be higher than that of Tiger Woods, right? =]

If you're on a tight budget, then you can try the Fountek FR88EX

Right on - budget will matter. Uncle will not be too happy if I spend too much

.

I've found something similar from the local market - but don't have any measurments on the driver - will try to get some and comapre against the Fountek driver.
