Tangband W8-1808 for Acousta cabinet?

[gshockd]

Hi all,

first off I would like to say that DIY Audio is really great filled with many great people. I’ve spent the last few weeks reading about how I should approach doing my own BLH.

it started with auditioning a pair of acousta 115s….then going through the Alfredo horn threads. I thought I was set on building the Alfredo horn with Tang band W8-1772 only to learn that the bass rolls off at around 60Hz. While the Acousta would reach 40Hz.

I’m not a big fan of Lowther drivers…..so I thought of replacing it with the W8-1808.

Could anyone give their opinion on this?

Tha Acousta does not go that low. And it wouldbe a really bad choice for the TB. Given the parameters of the TB no horn designed for a low Q driver (most of them) will not work well.

This TB really needs a specific horn designed for it. Scott & i have a rwequest to do such a horn but everyhting is currently on hold.

Hi Planet10,

Correct me if I’m wrong, I did a comparison with Lowther PM6A has a similar QTS? when I was doing research, I was even offered voxactiv AC1.9 which had a QTS of 0.66.

Are the other parameters the same?

To really know wyou would need to model it.

I built Acousta, i wa snot really impressed by the box.

Hi Dave,

Thanks for your inputs. I won’t same the rest of the parameters are the same.

I will do more research then. In any case, do you know of any BLH designs that can bring the bass down? Able to share them?
