Mmmm I can only imagine how hard 8x dual loaded T30s would punch... do it!

G'day mates! Just did a gig with my 2 OT12s and noted one of the boxes HF to be significantly lower than the other. It was to the point we had to attenuate the amp channel of the louder box and boost the HF of the quieter box in order to get roughly equal HF output. Does this mean I have bad element...

May I ask why you want to convert them? Interested to see what you end up doing.

Cheers, she punches hard

Interesting, thank you. May i ask you what genres you run through your t30, how you stack them (experiences with v-plating?) and what venue size indoor/outdoor you cater? I mainly do outdoor gigs/private parties (that being said, got a semi indoor gig coming next week on a rooftop). Usually anywher...

2c from a fellow bass lover. I chose T30 for the extension and I can tell you that with modern day track mastering being as beastly as it is, volume is NOTHING if you can't hit the low notes. But, I'm fussy. I dont like hearing low end drop off when content is there, it is not pleasing at all. Choos...

Merry Christmas fellow enthusiasts! May the bass flowww

Just a quick review on this. I ended up loading the subs against the house as planned and it worked out perfectly. Plenty of headroom with the pair of V plated T30s. Didn't get many photos of the setup but can see it below.

How good!

Question regarding the damping foam inside the OT12s. Looking at the sketch up and build threads I do not see people putting foam on the backs of the horn panels. Only on surfaces facing the back of the driver cone (top/bottom/back/sides). I assume this is just to damp the direct reflections from t...

Hehe guilty as charged.. I definitely am more biased to the low frequencies

If I do setup against the house, the subs will be a foot from the wall.

Yeah ok. So at 35hz that's about 2.5m.. I'll see how viable it will be to aim at the house.

Cheers!

Thanks Bill. Would I be better off then setting the subs up facing the house to fire out onto the grass? Or just setup firing directly out from the stone wall. I could try a few different setups as I'll have a bit of time to play with.

Brains trust, I am doing a small 2xT30 / 2xOT12 setup in a mates backyard on a rural property this weekend. Examining the low quality pictures below you will see my proposed setup idea. In the interest of maximising SPL I'll be Vplating the subs, and I'd like to utilise the small stone wall structur...

Mate, solid build thread! It's easy to see progress pictures and think how easily those cabs are coming together, but once you've built some you know just how much work has gone into each progress pic! Looking forward to seeing your herd fully assembled
