Re: Finally! Omni 12 Tall Boy build

I am interested to see the results because inside I had a decent dip around 2250 that I couldn't get up no matter what. Yeah, when a dip doesn't respond to EQ, most likely causes are inter driver phase cancellation or reflective cancellation from the environment. A lot of times, if you change the m...

Re: Finally! Omni 12 Tall Boy build

Final detail question. Optimism is a good thing. :lol: I agree with Bruce. Since your going to want the test signal 10-20dB (20dB is better if it's not too loud) above the highest point of the noise floor in the frequency range you're testing, the further out you go, the louder it will need to be (...

Re: Finally! Omni 12 Tall Boy build

Oh... I forgot you also plan to build a J12 Lite. I'm V E R Y curious to hear your impression of the two once they're both all tuned up.

Isn't there a way to pair up 2 speakers to one Bluetooth? My imagination is running to a wireless, battery powered, sub and top.

Re: Another budget driver option?

I just went back and read through some of the conversations we had earlier this year. Don't you also have a 3015LF you can put in the T48? Running both drivers in Hornresp indicates a maximum SPL at 40HZ with the GRS 15PT-8 will be approximately 112dB. Max SPL at 40Hz with the 3015LF would come in a...

Re: Finally! Omni 12 Tall Boy build

It's the speed bumps that make the finished project so much more rewarding. That's what I always tell myself, anyway. Whether it helps or not in a moment of despair and frustration is hit and miss.

Keep at it. You'll get it sorted sooner or later.

Re: Another budget driver option?

...I'm also planing to run at rms power out of the cab for an extended period of time to look at the thermals. It's also worth mentioning, this is a really bad idea and could potentially damage the driver from over excursion, bottoming out the voice coil on the backing plate or the coil exiting the...

Re: Another budget driver option?

Hmm. Not sure where I got the notion that the cones of some HiFi, Car Audio, and budget drivers not being able to withstand the pressures of horn loading. I thought for sure I read it in the plans. But, that's not what it says. Oh well. Good to know. Thanks for straightening me out on that. :thumbsu...

Re: Another budget driver option?

Wait... I found a function in Hornresp I didn't know existed. If I Sample from the "Accoustical Power" window, it indicates "Horn throat peak sound pressure" Sampling from 40Hz to 125Hz at 41.8 volts indicates the highest peak pressure of 2014Pa occurs at 40Hz and also again at 1...

Re: Another budget driver option?

It's not likely at all that Bill will consider recommending anything outside the stated limits of the enclosure. I'd say, if you wanna try it, try it. If it's not actually loaded the same as if it were a frequency within the designed bandwidth, so what. My guess is that driver will do just fine and ...

Re: Finally! Omni 12 Tall Boy build

Looks like you can also adjust Q in the same way. Choose a point in the drivers native response curve that's about half way between it's highest point and lowest point in the bandpass to be your target centerline. It doesn't have to be exact. Bring the broadest deviations to target level first. Then...

Eh, it's really unimportant anyway. Was just curious.

Should be fun. I'm excited for you.

Re: Finally! Omni 12 Tall Boy build

As it sits with the same tune as in the video it does 29.2v to the woofer before clipping on a 36v DC supply. On 24v DC it made 21.4 and seemed like noticeably less output. I am just messing around getting familiar with all this stuff until I get the mic. Difference of 2.7dB. "Seemed like noti...

Re: Another budget driver option?

Yeah, I'm scratching my head over here. Thought we sorted it out. Anyone what?
