The only possible defence I can find for them is that the speakons are cheap china ones I bought when I was on a low budget. No idea if regular speakons are harder...

I did check the amp, it's fine

Not sure if I should post this here, yet here we go! Friends of mine borrowed my OT12's and subwoofer with my NU12000DSP amplifier for carnival this year! Installed them, and things were good. When I got them back, the guy told me: This speaker was making *plopping* noises (at day 1, before the part...

Hey, patrick! That reminds me, i still owe you an email! :oops: You're missing the point there, the chart was to show the lowered roll-off. That 6dB is because it also adds double power, i've put te cabs 4S 4P, so the same power is used. But let's compare it same way bill does with the(same sized) 2...

We are still figuring out howmuch battery capacity we can get, but we'd like to have 100-200Ah @12V. Coupled with about 100Wp of solar power. I'll be using a single TDA7498 for the OT's. They should get about 80W each. I'll use a single TDA7498E for each sub. 220W @ 3 ohms. Actually the nominal impe...

It will reach it's Pe and xmax at about the same level, 34V (400W). On it's own it will do 122-125dB. Not that it's important, because i'll be running them at half power. Can't supply that much power with battery's and cheap amps. Now i don't know what the max-spl of a t39 is. But IIRC it should be ...

Thank you! And will do! I don't build a bfm sub because i can build 2 tapped horns for the price of a suitable driver for one bfm sub. And if the hornresp sims are accurate, they shouldn't be underwhelming. Coupled they should have a sensitivity of 100-103 db/m/w. Useable frequency range would be 35...

Hey everyone, I'm Jory, from the Netherlands, and plan on building an OmniTop12, and some time later another. I'm 22, and almost graduated electrical & electronics engineering. My goal is to go loud with (relatively) little power. The sound system i'm planning on building will be low-budget, pow...
