Probably the most important tutorial in car audio. Thank you for this!

it is a pleasure to see someone actually doing true tuning and not just apply crossover at the software and thinks he has the best sounding system .

Good job dude!! you're a legend. Audio forums are filled with very rude people with whom asking anything is a death sentence, good to see someone who can take his time to make these videos especially for a guy like me who's getting into 3-way active with dsp.

I don't often comment but I feel the need to because your videos are so helpful and so well explained. I have learned so much from you just in the couple videos I have watched thus far. I just keep having more and more "ah ha" moments. Thank you so much for the work you put into these videos!

This is by far one of my favorite channels when it comes to REAL details. Anyone can make videos on crossover points . And how you can play with different slopes to create a flat signal. But is it flat? It’s the phase !!! Thank you!!!

Really great job giving detailed explanations......you along with pssound have taught me so much about sq in car audio

Google must have sold my voice data to this man, because I was just talking about trying new crossover points for my setup, excellent video!

You are a great teacher! Thank you so much for your easy-to-understand detailed instructions and information. I would still be lost with tuning and REW if I didn't have your guidance, thank you thank you thank you

Hands down one of the BEST explanations I've seen. Nerijus..glad you fired your channel back up!

I found it very helpful for tuning my new DIY Desktop/PC Speakers. Actually just the understanding of how each factor affects the other factors is priceless. Electrical crossovers with certain slopes and power outputs may be a good starting foundation, but the actual Rew acoustic responses are what you want to tune for as they are what you are going to hear coming out of your speakers. I cannot imagine using Analog speaker tuning like all of the 20th Century and part of the 21st. Now with DSP you can cut out the cost and tedious labor of Inductors, Resistors, and Capacitors and ultimately achieve a very fine acoustic tune of your speakers.

I'm very gratefull for your videos.

Bro... you are amazing, thanks for share your knowledge I really learn a lot from your explanation...

great video ... the collection of information is starting to make sense .... that said Ive never seen a car with front AND rear sub ....

Very informative video❤

I currently run some 2.5in full range drivers on my dash and they are crossed over at 200Hz. I let my rear deck drivers cover 200Hz to 60Hz, and let my sub (IB18) cover 60Hz and below. Eventually I would like to get a couple more amplifier channels to try and do a bit better. But as is, it's very enjoyable and my 2.5in drivers handle 200Hz+ like a champ. Plus them being $10 each driver, I'm never going to blow one, but if I did, they're dirt cheap to replace. And sound 100x better than in door speakers. Thanks for the awesome in depth videos!

Thanks!

I really appreciate your videos and the instruction. Does the Left side acoustic speaker response dictate where the Right side speakers should be crossed over?

This was very good and thorough thank you. As I know when a driver is acoustically following a smooth response after crossovers and EQ, their phase response will typically be smoother as well. Will choosing a non-linkwitz crossover electrically in a Helix DSP cause any concern with that? Such as a bessel?

I’d like to suggest discussing crossover parameters and the results using the term electro-acoustical. You refer to it as acoustical but, that’s no more accurate than saying electrical only. The response that you end up with is a combination of the electrical from the crossover itself plus the acoustic response of the driver/enclosure. At its heart it’s equivalent to having two filters in series and you can’t expect to arrive at your target response without taking into account the characteristics of both. They impact each other in both magnitude and phase. The end result is to get the combination to perform to your target, not to make the crossover somehow deal with the driver response. You sort of allude to the concept but, don’t clearly point it out.

Perfect timing. I'm selecting crossover points right now. In REW on the EQ tab, I don't have the crossover selections at the bottom. I believe you have a Helix and I have a JL twk. Assuming the twk doesn't have the ability to model crossovers in REW, how do I get around this limitation? Take readings of each type of available crossover types with different slopes on each?

Perhaps I missed it as it was a fairly lengthy video but its worth mentioning the potential phase issues as you change the order of the crossover.... a possible follow up tutorial?

Nice presentation with REW. I have a question that how can I get a target curve shown in 'All SPL' windows and EQ windows. I know there is a target setting in EQ option but can't choose the filter type like Linkwitz...

how to choose subsonic filter setting plz tell me

QQ...if say you're aiming for a 400-3500 LT4 XO for your mid ranges to the tweets. It is okay to have different electrical cross overs in your left and right Mid ranges to get there? Or should they be the same? I assume it is okay based on the video but double checking as there is differing opinions on the web!

I have a 2007 GX470 the Mark Levinson audio system. The entire system uses 16OHM speakers. It's becoming increasingly hard to find car audio drivers that operate at 16OHM. The rest of the system is impressive, but I can't help but think that it would benefit from a driver refresh & upgrade. What should I do with lower impedance speakers in order not to put the amplifier in jeopardy? I've looked for the ML specifications without result.

What software are you using?

your videos are good but here I just wanted to point out that in this video at 2:23 min there's one small correction that is to be rectified. For tweeter hi-pass should be of either 3kHz or 3000Hz and not 3000kHz

using REW how do I see frequency / driver summations ??

If my mid bass was cross at 900hz HPF in Rew to match the acoustic crossover of 75-250hz Should I use the 900hz as HPF at my DSP or 250hz?

I never see anyone using xovers with steeper slopes for example 48db/Oct. Anyone know why that is?
