Full Range EQ

There are 100 in the store already, and in process of being listed.

If you download and install MicroCap as described in the article, you should be
able to run this simulation and you can play with it, altering the values, running
overlayed curves for ranges of values and so on.

A good opportunity to learn MicroCap, which I think is the easiest thing for
beginners and lazy people like me...

I also have EQ files for some specific full range drivers, so I will post them as
I have time to go through them.

Up to this point I've resisted the urge to go into the rabbit hole of speaker building.

However this article has now pushed me over the edge.

May I ask what drivers Mr. Pass is using in his article? It seems like they might be a good place to start - always good to start with a known entity. It would also be wonderful if there was an enclosure plan to work with the drivers.

Some known examples are the SEAS FA22RCZ. It worked great!

Needs phase plugs: http://www.planet10-hifi.com/downloads/B200-phase-plug.pdf

You need to add. couple divots in the base to accomodate the not completely flat pole piece.

EQ:s 🎷🙂🎸

This is how they did it on my favourite old oldschool amplifier that i really recently finally bought back. Gonna fully recap it for good old times sake. ❤️😘❤️

The Bass EQ button was a favourite feature back in the days. If i remember it correctly it lifts the low bass around 6 db and does at the same time a light attenuation of the extreme low bass.

Nelson,

I am still laughing the result of your EQ. 20 years ago, it would have been just the ticket for me, but now, my hearing has a pretty good dip from 4-6K. In addition, the drivers that I am using are bass heavy (who woulda guessed). I have actually had to bi-amp with a sub to mostly solve this problem. Life is a head shaker.
Hell, I would of enjoyed building this if my system/hearing had warranted it.

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.

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

BTW, what kind of tweeters are on that picture? To the left of the amps? In your included PDF?

I do miss the old Radio Shack catalogs. They were great reading a great source of inspiration and expenses.

Thanks... sounds like a great project to get back into soldering.

Thank you.... I didn't know that. The perfect page to browse with my tablet while I smoke a cigar.... It makes me feel like a teenager again!

:):)

Wow... it looks like a Superscope with Marantz speakers in the background...

BTW. I still have my fancy Radio Shack analog multimeter from '79.. it works fine too. Like my wok and a couple of audio components, they predate my wife!

Anyhow... still waiting for the DIY audio store?
