Full Range EQ

[WBS]

Hmm... I don't see them...

I’m thinking they arrived at the warehouse but haven’t yet been made “live.”

It's great that NAD had turnover frequency options. I think that a few other brands did as well. Yamaha had the loudness control that really impressed me by reducing the mid frequencies as you turned the loudness dial instead of pumping in more bass/treble.

Yea, i think that you are on to something here.

Wether i am using all digital DSP processing as in high end car audio builds, or all analog EQ in home audio, or all digital DSP EQ adjustments as in home cinema setup:

Less is always more. Always!

Less BS is simply always purely, scientifically, and clearly less BS in your system.

Get everything tuned. The room, the crossovers, the placements. The enclosures.

And then, only then: Lightly EQ. Always aim to subtract, try always to avoid boost.

Because boost will always strain the chain.

$150 amp, $10k speakers. I know the amps good. Lots of really decent FR drivers for MUCH less, particuarily if you diy the boxes.

what kind of tweeters are on that picture?

JVC?

I recently found a very similar single while doing archeology in my office.

Well? Lets keep it powerfully juicy and real🙃

Absolutely No EQ what so ever needed here 🎷🙂🎸❤️

No tone deaf, fully ear waxed mixer dude/producer in sight? So crankit up 😎

Dave-

$150 amp in parts... + 20 hours to build/test + at least $40K in Nelson's time.

People underestimate the cost of IP (intellectual property) and labor.

What are those tweeters to the left of the amp in the background? Next to the XA25 huh? JVC you said? HSW1101-01A Leaf Ribbon?

​

 

[WBS]

Pioneer TAD ribbons?

 

[Nelson Pass]

BTW, what kind of tweeters are on that picture?

TAD ribbons. They go to 100 kHz...

eq in my main system...would be nice to make it analog with few jfets instead of adc/dac and computer in between

It would help if we knew the vertical scale.

The EQ for Full Range Drivers is now available in the store.

I wonder if the bass section could be used to "boost" the bass driver in a open baffle speaker?
Most have a bit limited output below 35 Hz.

It has been done already. Read the SLOB article. In the bass sectrion, after the active crossover, you will see this EQ. I tried that, and worked very well 😉

 

[MEPER]

Ok, I will take a look at the SLOB article.........

Papaled: adding special voodoo since 1973 🤣
[EDIT] Thanks, @Jason TAKEN!!

Hallo Mr. Nelson, i was half joking. Behringer ultracurve is pretty decent in being transparent. It does eq without adding much signature of its own. Unlike 31 band analog behringer.

For me, who constantly changes preamps, amps, speakers or other components, having an adoptable eq is essential. Ultracurve can quickly sweep and save the settings. So essentially, i am happy with it.

Marvelouso! Completion kit close or is it best to grab a board/basic kit at once?

 

[peppennino]

Would a 10K log pot be ok at input for volume control? I don't need a voltage gain since the power amp will be a little Moth Stereo and this board already has a buffer at putput.
Can I swich R3 to a 10K res in series with a 10K pot in oder to be able to vary from +3 to +6dB the bass bump?
Thanks

I have a pair of Liisong F15s. Even after extensive break-in, they still sound a little thin and require a high crossover point with my sub. Quite happy when this popped up...might be just the ticket!

there is no voltage gain per se, main cell being buiffer

Hump and Bump are adjustable in circuit

A series 5 watt resistor between your voltage source amp and speakers might get you a long way too (start with a pot, find the ideal damping/critical damping/your own fave. And then you can fine tune them with the EQ.

An igniramous question - is the dip at about 5K specificaly designed for a FR+whizzer? I had the Lowther so know the presence it gives. Now I have a whizzerless FR - Fostex 4 inch.
