sounds like an excellent plan. the "made in england" pretty much confirms those knight drivers are goodmans.

Yes. I’m curious about the mids. They don’t have much on them to denote manufacturer.

Likely I’ll sell the knight branded drivers. They don’t interest me.

Cleaning up the drivers I pulled and the midrange speakers do have Made In England on the side of the magnet cover. But I can’t seems to find any instance of a Goodman’s 6” with a solid basket.

That’s a great looking cabinet design, I prefer them without the wood lattice grills. I think in a cool off-white fabric they would really pop.
 
That tweeter crossover is a J-Rob special: just a cap and a pot centered at 5,000hz. The first thing I would do is connect the 414 full range and connect the tweeter through the existing crossover. The 414’s are about 96dB so I would hope that the Trebax can match that.

If you continue on your plan with the 802’s and Emilars I would suggest looking into the 32343 crossover. The HF section includes an equalization circuit that works really well with the 802. The LF may or may not be connected. If you use the LF section you may choose to eliminate the zobel. Based on the advice on someone online, I bought a pair off of Ebay specifically for a HF inductor in the tweeter section. I’ll reuse the faceplate and HF level knob in a pair of outboard crossovers. I have a pair of Mast Mutter 1dB autoformers that I’ll connect to a 12-position switch.

I happen to have giant roll that meets that description. The brown cloth was stapled on... I just ripped it all off and cleaned up all the dust behind. The design makes it pretty clear how grill frames are designed to work on these. Shouldn’t be hard to whip some up.

I love that your workbench amp seems to be a McIntosh 2205:

And were you making bitters?

That’s one of my pair of MC2205’s waiting their turn to head to Audio Classics.

No bitters. Those bottle were from a whiskey tasting I hosted on Friday night. Just filtered water for dripping into the tasters... gotta get that bloom!

i'm no expert but i do have 604s and tried them in a series of progressively larger cabs. 612s were certainly too small to get any bass. even with the much bigger cabinets billfort has he is using subs. i am using JBL 4648 cabinets, each with one 2225H driver for bass assist with my 604Es. your mileage may vary:)


Hey, I just bought a pair of JBL 4648's with all the woofers just for what you made....


How does it sound altogether? What XO are you using? I'm considering using 2 minidsp 2x4's....

Hey Woody,

Not trying to throw off the subject, but I'm wondering how's your 604/minidsp project is coming out/sounding?

cool! i am using a miniDSP to bring in the woofers. i forget the slope right now but pretty gentle. i think my crossover point is around 150hz (everything packed away right now; in the middle of moving...) i run the 604s full range but, of course, there is a crossover for the 604 itself (i can post the details of that but it is modified JE labs). i have separate amps for woofers and altecs and separate volume controls so can boost/or reduce the bass on the fly.

sounds wonderful! that midrange to die for that everyone talks about. but i need a woofer helper of some kind (same w my open baffles, i use a helper woofer). the 604s are sooo efficient, you can use fleawatt amps. i use an amp that runs 2A3, 45 and 46 tubes.
