126 + 9 = 135?
and that is just from 4.

and then I'll put them on the floor, in a corner.

This is going to be fun!

Very interesting stuff!
But I'm a bit confused, how low go these and what size are they?

That's not 1m testing...What voltage was Applied to the drivers to get that?

That's right. Testing was not at 1m, nor at a specific voltage. No such claims were made.

When I do proper outdoor testing with sine waves at measured voltages at 1 and 10m I will be happy to share the results. As said above, this was no more than playing the mono summed bass from music (using the iPod) through a basic dj mixer and 45W rms amplifier. This was in a relatively small room and too close to walls, the ceiling and floor to be considered a room suitable for measurements.

If you want serious data, this is not it. I only wanted to have a little proof of concept, to see that my work had not been wasted so far. When the snow has melted and the ground below it is no longer frozen solid I shall do further proper testing.

Regards, Ben

Not sure if it's been posted but the 5100's are on special from parts express right now for $880.

I still wouldn't buy at that price but just a heads up!

Talk about back from the dead. This project was scrapped when TC revised the pricing on the 5100 and it became 1500$. Even at the 880$ "special price", no driver is worth that. I think they were 550$ originally at the start of this one.

I built 4 18" loaded 23hz vented cabs with FaitalPRO drives and they kick serious tail. So do my new line arrays at +/-1db from 300-12k with 2 bands of EQ.

Honestly, I like the visceral quality of the vented cabinets. Standing in front of the 4 new 18s and a pair of 21s is a truly engaging experience. When the concrete floor under the rig modulates, I'm doing something right. My FR, waterfalls, and impulse response turned out exceptional. I still need to encounter the right conditions for THD measurements. The vented Faital cabs are the first I am happy with and would put my name on for resale. I'm going to build 4 more, they are simply nasty. The kickbins are going to get a redesign next. The subs and tops are settled. I do need to execute a few small baffle revisions on the tops.

I am the closest I have ever been to the system I have been envisioning for almost a decade.

Default Interesting - full circle then, but with much better drivers...

Wisounds,

thanks for inspiring the project that I adopted! Can we take a look at your new system? What are your frequency response -3dB and max spl specifications and drivers?

Regards, Ben

I just reviewed the thread, I'm glad you were able to get a cabinet out of it that suits your needs!
