Default Which TB fullrange 6" to 8" CC in small BR enclosure?

My friend has a pair of 2 way Paradigm (8"+tweet), a 12" JBL sub. Space is limited to 1.5 cu. ft. for the Tang Band.

I don't have a polar response of the tang band w8-1808 but it should be conical I suppose. This fullrange seem to be well appreciated for it's midrange. The CC doesn't need to go low (100Hz). What would be the best for it? Ported or sealed? He doesn't want OB because of space constraint.

I talk about the 1808 but any TB between 6" to 8" that would fit in a small enclosure would be ok.

I would like the simplicity of a fullrange and a good horizontal dispersion. Probably a carpet on the floor for 1rst reflexion because it should be under the 52" plasma.

What do you think?

Thanks

Well, does it have to be a Tang Band driver?
The alpair 10.2 is a better choice if you only need it to reach 100 hz.
Better dispersion, better FR, much smaller box than the TB w8.

And why go vented if you are only getting it down to 100 hz?
Better off with sealed I think......
Or my favorite, aperiodic

fullrange speakers, especially larger ones (4"+), beam/aim the high mids and highs = not much dispersion in any direction! so there is only a small spot where you receive the full frequency range. an added bass/sub does not aliviate that problem imo.

if you are looking for a larger listening area two (or three) ways is called for.

Here, Bob Brines uses the lower Q model. It will have the same dispersion.

Sayrum is correct though only if many people are sitting around the TV.
If it's for 1 or 2 people sitting next to each other a full range is perfectly fine.
Although the CC will not match the mains as far as timbre.

as seen in the first graph (frequncy response) an bobs page, starting at 2k the dispersion narrows considerably...

i have listen to and enjoyed the w8-1772, but the only spot with decent highs was right smack in the middle between the two speakers = only enough room for one person imo.

Well, at 15 degrees it's looking good.
2 people can easily fit in a 15 degree window at 2 meters.
3 people could fit at 3 meters, if they were very good friends
But, I believe all front speakers should be identical for timbre's sake.

If what I see is the 6" would be preferable dispersion wise. The distance at the listening area is about 7 feet. The paradigm are (I guess) around 87db efficient . I should take a look to the size of their woofers too. TB 6" are around 91db(W6-1916)

A two or tree wayy (would prefer tree way dispersion wise if it is in a d'apollito config) but xover and cabinet height are of concern.

So in a sealed box for the W6-1916, the dispersion could be ok for the listening distance?

I'm shure that for what I've listened from hi CC d'Apolito (WTW) the dispersion is so bad, the sweet spot is much narrower compared to a single full-range or coax...

Maybe it's just mee

The oft seem horizontally oriented MTM is a sonic disaster, foisted on many by the marketing people.
