Default low level fullrange?

OK, strange title but bear with me :-)
I really need you guys to help me here please...

I got myself a nice new LEDTV (looks good, sounds awful) but there is no room either side for speakers. The only place I can put them is in the cabinet below which has straw grill doors. The whole thing sits into an alcove.
Is it feasible to put a fullrange set into this cabinet and get reasonable sound? WAF dictates that I dont have anything above the TV
I could make a couple of enclosures and slide them in behind the doors with wadding around them. I could also angle the front face to raise the axis of the drivers away from the floor

Size of the enclosures (max) would be 10" x 8" (front face) x 16" deep.
These would sit right up against the door grills
I could also put some tweeters around the back of the TV and fire them against the wall?

They could be sealed or maybe even folded horns ... now that would be cool

What do you think?... Silly idea? I have many class D amps that I can use for this, they are all around 20 watt ......

If feasible then could you recommend a driver for such a position & enclosure volume?

Any help you can give would be VERY much appreciated chaps.

Cheers
Lee

Would a simple FF85 base reflex work OK do you think... or should I go for bigger drivers? I can mount the drivers at an angle so that they are pointing up and away from the cabinet.... I'll shut up now and wait for the experts

That's a tough one!

Your size requirements and low power amps would need all the help they can get. Throw in cost and it gets dicey.

Aurasound NS6 Speaker Kit - 4 ohm Woofer - Parts Only: Madisound Speaker Store

The above kit includes two 4 ohm (8 ohm also available) six inch woofers, two dome tweeters and two crossovers to build a speaker for $95 US. That would fit your budget but I have no idea about shipping. I do know they are quite efficient so would provide plenty of sound volume with your chip amps and at 0.45 cubic feet--they will fit in the space. Ported they go down to 65Hz so if you feel the need (or can hide one) a subwoofer can be added later.

FF85wk is a very good driver, but you hardly need the kind of volume you have available.

Given that blueplanet has CHP70 (1st gen) on sale, i'd consider them.

These work quite well in fairly small vented boxes, certainly small enough to fit in the cabinet, although you might need to "make adjustments" to the doors' straw grilles. It wouldn't be too hard to juggle dimensions to allow for a 5 - 10 degree tilt of front panel.

Movies require good bass for maximal enjoyment. Easier with a bigger driver. It seems that the fostex ff205wk can offer that, in a simple bass reflex box. However you will need to add a tweeter as it lacks sparkle in the highs.

why not do one cap for more internal volume/smaller size and tilt it slightly up to get all the highs?
