Default TangBand W4-655SH?

I need to make something cheap for my bedroom (again) as my brother nicked my W2-803SM towers. So yesterday I randomly picked up a pair of these drivers at my local dealer since they were on 50% discount...

Anyone have any experience with this driver?
Searched around a bit on the interwebs without getting much smarter.
It looks similar to the W4-655SA (which is used in Cyburgs Sticks) but there are some differences according to spec sheets.

I know it cuts of relatively early, but otherwise it looks quite nice to me.

I am also interested in this wide baffle type of design simply because I like its look, but what exactly are the Cons and Pros of such a design? I am trying to avoid using a BSC, so large baffle/face plate seems to be a possible way to go, yes?

Just an idea - Fruhal Horn FH Mk3 maybe? It accepts a wide range of 4" drivers, though not sure if anybody has used this particular TB.

You might need a tweeter later to augment the highs.

I am no expert, but making the box very shallow might have a risk of the backwave bouncing back and causing coloration to the sound.

Thanks. Putting it in a Frugel might work, and of not I could always use the boxes with proper drivers later..

But back to the flat box idea for a second, how about if I make it as a TL or something internally? That should get rid of bouncing waves?

Sorry for bumping, but I have searched on driver placements in Transmission Lines without really finding a answer for this - can the driver be mounted on the side on a folded TL like illustrated?
I have some materials and really want to get started this weekend

AggroMagnet,

I have no idea on TL design. Have you looked up the TABAQ TL? It's for 3" drivers, but 4" TB drivers have also been used IIRC.

Edit: Here goes the link:

I will (probably) be building those for some W3-871 I have, but thanks for suggesting them.

My saw is calling me.. Flat speaker needs to be tested. Will report back with pictures.

So I stopped by Ikea and picked up some kitchen closet doors.
Still in the test phase, but it seems to work just great. Deep and dry bass.
Ports are placed on the end of the underside (2x8cm opening on the port, might be a bit on the small side, but barely any air seem to come though it anyways..)

Used these for about a year now, very satisfied with the W4-655sh.
However I found them to be lacking treble after break-in so I added a tweeter with a 1,8uF cap. Happy with the end result, keeping these for a while.

A little clip for anyone interested (sorry for the quality as usual):

Your wide boxes look nice. What does the inside look like? Is it a TL or BR? If you like flat wide baffles look at the flat BIB or FIB - details in the Foam Core thread.

It is split in the middle under the driver and down, ported on one side facing down. So a kind of a folded TL I guess.
I have considered BIB in the past, but haven't seen those FIB-horns - man those looks interesting..
Might finally have found an excuse to buy seas coax drivers, thanks!
