A single 18TBX100 has more displacement.

As for what gets louder, well, depends on the setup.

Guys thanks for the above info and links.

This is what i am after efficient and going low with 4 box per side

Most of the design using the lab12 or flh. if 2lab12 in a flh is more efficient and go lower than 2lab12 in a tapped horn. i would use a pair of lab12 in the bass horn Epa design for me.Bass horn would need modification to fit the lab12.

The 18tbx100 is known to be used in tapped horn, if the 18tbx is more efficient and go lower in a tapped horn than a 2lab12 in a TH or FLH. I would use the TBX in one of Epa design.

speaker price

2 lab12 $ 322.00

18tbx $294.00

Which way to go

Hi kornnylike,

Going back to wood1y's thread: 15" tapped horn with RCF I found a nicely documented tapped horn by Xoc1 that actually seems to work fine with the factory T/S parameters of the B&C 18TBX100. Hornresp calculates the V_net to be 454 litres, so this might be the volume range you could use to compare other designs to.

Regards,
