...I do not find in power amps what is the voltage given to the drivers...

To calculate Watts from Volts: Volts times Volts divided by Ohms equals Watts

To calculate Volts from Watts: The square root of the product of Watts times Ohms equals Volts

Alright.....after all the mind-numbing repartee about crossovers and impedance and other crap I don't understand. Here's what I'm doing while ya'll are talking theory....... Pfffft you're not fooling me. "what would I know, I'm just a truck driver". "what would I know, I'm just a farmer". "what wou...

Hahaha. You give me too much credit Rich.

Alright... https://www.facebook.com/bruce.weldy.3/posts/10222778003191846?notif_id=1626398033587407¬if_t=feedback_reaction_generic&ref=notif Had to put my headphones on to get a good feel for it. Bottom end is definitely there. The singers are nice 'n tight with the harmonies. Good mix too :thum...

Hey Joey :thumbsup: I assume this is for your J12 Lite. I haven't (yet) built one of those. I'm sure there's actual experienced opinions to follow, but my inclination would be to do the simplest solution. Then see if there's any vibrations and go from there. Also, try your best to keep the screw len...

Cool little KL3010LF review on Amazon...

KL3010LF-8... Amazon has 2 in stock and I saw 1 in stock for a Reverb seller at about $20 less than Amazons price I sent an email to Leland to change the order, I want the 3010lf now. I am waiting for his answer… The alpha 6 are sold out too and I will have them at the end of this month. Regarding t...

...I don’t know how much power I need to take advantage of the speaker system The Kappa Pro 10LF in a T24 needs to be limited to 45volts. To calculate watts from volts... volts times volts divided by ohms equals watts. So, the subs would need an amp of at least 250 watts to get the most out of the ...

Ismael... welcome to the forum. :thumbsup: Contrary to J's opinion, I personally like to minimize my use of rack space. There's good reasons for either avenue, so it just boils down to your preference and goals. Personally, I'd run highs and lows on one 2 channel amp before going to 2 amps. I haven'...

Searched the HOLMImpulse user guide and can't find any indication of the value (peak or RMS) it uses. Also, here's a little excerpt I found in the SMAART SPL Quick Start Guide that may be insightful Peak Measurement Peak C Peak C shows the absolute maximum value reached within a measurement period. ...

Unless specified otherwise my charts are 2.83v/1m half-space, measured with a pink noise signal.

I remember having the conversation, but forget what you said you use for your graphing... is it HOLMImpulse?

...which way should i measure my subs to compare to a TEF chart like danley uses? flat db peak, or flat db regular/rms? do bills charts use 2.83v 1 meter db peak or rms/none peak? I'm gonna stick my neck out and say RMS on both accounts... I did a quick search through the SMAART User Guide and foun...

They're not a global economists, but it's still good to hear indications that things may returning to normal in the lumber market. Maybe. Fingers crossed.

That's another good point to bring up :thumbsup: I don't know if it's the case for all curves or not, but Linkwitz-Riley is already down -6db at the designed crossover point. Butterworth -3dB. Will be interesting to actually measure that too. Mmmm yes that's true. What is "odd" about that though is...

Oh, and one thing I forgot to add. Crossovers/filters reduce power by a set amount in dB per octave So, if the reduction is 12dB/octave from 100Hz then there will no or minimal reduction at 100Hz, but should measure -12dB at 200Hz as an example... That's another good point to bring up :thumbsup: I ...
