Hello everyone. I got a gift from a friend a of mine it is a new pair of yhe Tang Band W6-789E driver's. So There are so many box types out there to choose from? So Here's the two box types am looking at building? The first one is a Bass reflex and the second one is ported box? ( I hope they don't mean the samething? ) So am looking at a nice stand mount or monitor speakers that I could use in the corners with out to much trouble . ( Like audio note does with there speakers?). I Hope you dyers can point me in the right direction? Jeff.

Welcome to Diyaudio! The members here have a wealth of information and some have very strong opinions. Enjoy the information, and don't get upset if somebody disagrees with you.

Bass reflex is a ported speaker box. It uses the box volume and port dimensions to get the best bass response.
There are actually many types of ported box designs. Bass reflex is the simplest to design and since you only need to worry about the box volume and port dimensions.
Your speakers only go up to 10,000 hz. You will probably need a tweeter for these drivers. You may need to ask your question in the Multi-way forum to also get tweeter and crossover recommendations.

. Thanks I will look up the program and see how it works? Jeff

You should do some searching on the internet about this driver. I did a quick search and find that it is a woofer - meaning meant for lower frequencies. It looks like a nice driver, but you may need to pair each one with a suitable tweeter to get full range. I just saw this thread: http://www.diyaudio.com/forums/multi-way/265310-tang-band-w6-789e-driver-help-best-possible-box.html
Thanks for your help. Still new to this driver. I know it doesn't go to 10khz. I do have a test ribbon tweeter already am going to fool around with in-till I find what crossover point sounds good. 
Jeff / Also thanks for the post link. Here's the description from the help function on the speaker designer website;
The most important question is what type of enclosure to use. For the novice builder, conventional thinking says a sealed enclosure will typically produce a more accurate sound. A ported enclosure will produce louder deeper bass at the expense of sound quality. The ported enclosure also requires a more volume. A 4th order Butterworth Ported enclosure is even larger than a standard ported enclosure, but it should provide a smoother roll-off.
Note, where the help file says "The ported enclosure also requires a more volume." it means the box is bigger than a sealed enclosure.

Hi,
Easy as pie ? I don't think so.
The driver has nice sensitivity due to a lightweight cone,
and consequently has a high Vas for a not too low Fs.
It peaks a little at and rolls off from 5KHz, so a two
way design is absolutely mandatory to use it well.
Power handling is low, a ribbon tweeter might work well.
A 4th order butterworth bass alignment will be a one note
wonder, and is the "standard" ported enclosure used by sims.
Classic butterworth vented is a huge (for a 6.5") 65L tuned to 44Hz. 40L
tuned to 40Hz looks good to me. 20L sealed and stuffed is good for a sub.
rgds, sreten.

Well I guess not as easy as pie. I was using the ribbon as a test point because I have it on hand and it was free. I planned on crossing the speaker to tweeter at 4,000 khz. As for the box type I will keep looking around in-till I find the one I like ( a one note will never do this driver justice ). Thanks for the heads up and your insightful wisdom on this subject and my driver. Jeff
If you don't mind me asking? What box program are you using to get the box sizes? I just would like to learn like everyone else. Jeff
P.s. Why is my typing so small?
FWIW, I looked at this driver awhile back and it's suitable for a wide range of cab alignments, though for corner loading this narrows the field quite a bit since it will boost its bass enough to either reduce cab size or at least tune it lower and if hard in the corner, such as a triangular shaped cab to fit, sealed is probably going to be the best choice overall.
Anyway, for ~best power handling in a corner vented alignment: ~ 28.3 L net tuned to 47 Hz, otherwise sreten's 40 L/40 Hz.
This assumes a typical high DF SS amp, so if tube, then these may be anywhere from a little to a lot, too small.

Get a bigger monitor.

Thanks for your reply on the box program you use. Also yes a reg. Computer monitor is better then typing on a phone. Jeff
The W6-789E is an interesting high sensitivity driver. Thanks for bringing it to light as I was unaware of something like this. The published response is remarkably smooth and this may be useful as a mid in a transient perfect B&O hole-filler 3-way.
I had a suspicion it might work in Decware DNA, re-sized to 10in internal width. I ran the sims and it looks good with a smooth roll-off in the low frequencies. Even after 5dB of baffle step loss, the output is a respectable 87dB with an f2 of 50Hz. Not too bad.

Here is a 2-way implementation with an RS28F-8 for the tweeter with a 2kHz Harsch XO:
You could pick a much higher XO as this driver really goes up past 8kHz.
I use Akabak software.

You're welcome!
Then you can 'have your cake and eat it too' with a triangular shaped, tall floor monitor to raise the drivers up to seated ear height using 1/4 WL TL design except with a vent [aka MLTL] to get more bass and sound quality [SQ] referenced to a typical vented alignment [aka BR or reflex].
