Has anyone tried this Horn sub Jr?
I tried a different horn for a 12" peerless a while ago. The horn was 3x the size of the sub Jr. My horn produced too much output between 33-40Hz compared to 40-80Hz. Maybe sub Jr will work better?

I will most likely be using a Beyma 15k200 or something similar.

I'm bumping this up because I'm curious about feedback on it and I know William is on the forum. I'm going to see what an Eminence BP102 looks like in this box.

G'day Guys

Well I've tried a few of them :-)

In a domestic environment where they can be pointed into a corner, they work very well. A few hundred watts into one of these horns will give you some serious levels of high quality bass (flat from 40 to 150Hz). If they aren't faced into a corner, don't expect too much below 55Hz from them. They are a very compromised bass horn that really needs a corner to work as expected. Many 15" drivers seem to work well. Let hornresponse guide you.

Hi William

I just checked http://www.etonesound.com/ and the Etone 135 is not listed.
They do have a 10 inch Etone 1020 for only $A 71! that sounds too cheap to be good?

Voice coil 50 mm (2.0 inch), high temperature copper wire
Sensitivity 98 dB/W/M

It’d need a revised design. But do these TS listed, seem suitable for 40 to 150 Hz
Fo 70 Hz
BL 17 TM
Qms 4.18
Qts 0.23
Vas 30 Litres

Thanks

Don't stress over the Etone, there are a number of other drivers that work well. You'll be better of with a 15" anyway. Let Hornresponse guide you.
