It's chipped because I tried to use it unwisely once, I don't even remember what I was doing, but I remember my reaction at ruining the edge! I just bought it to do a specific repair, fix a screen door I think. but I find myself using it once in a while. Even chipped and dull it is still useful. I don't have a grinder to sharpen it.

I like vintage speakers too, Roger. I am supposed to be helping a friend sell a pair of old Cerwin Vega D9 dorm party speakers. :eusa_danc

I am in your area, near Kildaire and 1010 and I can regrind and sharpen your chisel; I have lots of sharpening tools. Based on your description of why you bought it, I am assuming it is a fairly standard hardware store variety. The WorkSharp has a built-in fixture for those.

Welcome to the site Rich. :eusa_clap:eusa_clap:eusa_clap This is a wonderful group of folks and it's great to have you here. :icon_thum

Thanks Trent!

Andy, I'll PM you, see if we can find a time to g2g. It's just a 1/2" Stanley. I'm near optimist/westlake.

I got some pics posted. Please check out my gallery.

:icon_thum Are those "full range" speakers?

An acquaintance picked up these in Raleigh last week . . .

They are 6ft tall :mrgreen:

sapwood, I can't see the picture because I was not registered at audio karma, but I am now. Once I get activated I can look at your picture.

Yes, mine are full range speakers. They have flat frequency response from 50Hz - 20kHz, from one, very cool little driver with 3.5" paper cone and a powerful motor.

Thanks Matt! Sorry for the slow response. It's good to know there are a couple speaker builders here. I will get some pics into my gallery today.

Your speakers look great! Vifa makes some great drivers. I have not done a passive crossover from scratch yet, I know it's hard to do the final tuning well. I use a digital crossover for my multiway projects. But lately been just single drivers.

I've built a half dozen cabinets around a pair of Feastrex full range drivers that I got a few years ago. I've built horn loaded reflex boxes, sealed, open baffle for those drivers, still experimenting. I built a giant sealed sub for a friend last summer. I'm starting to design a 3 way with Audio Elegance drivers, or maybe Accuton. Waiting for weather to warm so I can get cuttin. I don't have dust collection, so I work out in the driveway when the weather permits. I'm also thinking about building a line array speaker. I like to experiment. I want to make a spherical driver enclosures so I'm looking forward to learning about wood turning on the forum.

I buy speaker parts from PartsExpress, and Madisound. Most electronic parts for amps and such from Mouser. I prefer low order crossovers, 2nd order is OK, and I have a pair of commercial speakers with 1st order 2 way speaker. The steep filters I have heard are not my cup of tea, it's so hard to make good LR4 filters. So I use a digital crossover when I need a steep filter like open baffle stuff.

Doing a lot of experimenting with single driver full range speakers now using current source amplifiers.

Rich you certainly make some interesting speakers, Very Nice:

Rich's Loud Speaker.

I have wanted to make a full range loud speaker from a Fostex speaker in one of the below designs. The first I think will still look pleasing to the eye, well my eye. I like the TL in this box and would love to hear how it sounds.

I'd like to try this one because I have a lathe and it reminds me of the older style.

This looks simple and pleasing to my eye.

And these would be just awesome to make if I ever had the room~! They are called the KleinHorn

Here's a link: http://www.6moons.com/audioreviews/firstwatt/firstwatt_2.html

I did read somewhere that they had these in a Gym and no matter where they turned them, the cops kept showing up, they were so loud.

Maybe we could g2g sometime,

Matthew

Thanks Matthew! I am getting better with practice.

Go for it! Single driver designs are pretty easy, it's almost all woodwork.

I would not be surprised. It is a common theme in all of these single driver designs, to use plumbing and a amplifying horn to mainupulate the wave from the back side of the speaker cone to filter out the high freqs and amplify the low notes. Since the low notes coming from the tiny driver are so soft, the huge horn brings it up to the same volume as the higher notes. But the whole speaker is very efficient and can easily play over 100dB. I've met Nelson Pass he is very fun and creative dude.

I'd love it!
Maybe when I get my latest stuff finished we can have a North Carolina Woodworker audio meeting at my place. :eusa_danc

Matthew, that horn picture you want to build looks like a "spherical" horn. I want to build a spherical enclosure, like a beach ball with a driver in it. That eliminates edge diffraction and sounds great, but seriously difficult to make without a lathe or CNC mill. I hope to learn to use a wood lathe, maybe buy one for making stuff like this. I have a miniature metal lathe with a 3" swing, but I think I need 7" swing to make a 14" diameter ball. I have a lot to learn there. Check out Earl Geddes for info on horn shapes. There are several different shapes all claiming to be "the best." His probably is...

Hello Rich, welcome to the site. Great bunch of guys and ladies here, and all are willing to help.

+1 on horns. Earlier in the year I visited an acquaintance in Raleigh with this setup. I'm in the blue chair and a ~1.5 watt tube amp is powering the horns. Gotta love efficiency!

That is so cool, Roger.

Thanks Jerry!
