You need to change the capacitor value too. Good for the K-77, not so good for the B&C drivers which exhibit in-network rising response.

An Exorcist.

Would be more believable if they could only be seen with a camera outfitted with lenses designed for infrared or ultraviolet wavelengths.

Looks like a board from parts express.

Sennheiser HD660S2. On sale now for $450

Impressive. But I'm easy to impress.

Right, JBL did a lot of this with their monitors. It's not new, and Al certainly didn't invent it. Klipsch swamps some of their tweeters (I think).

Over the ear, or in ear. Big difference here in both sound and comfort levels. I mostly use IEM's for music, both Klipsch x20i and Sennheiser ie800s. My over the ears are Sennheiser 650's - which I mostly use for Movies. Comfort is important. No point in buying something that sounds marginally better than something else if you can't keep them on your ears for longer than 20 minutes.

It’s been several years, but Dave stopped building them because he developed carpel tunnel syndrome. After recovering from surgery, he went to kits only. He was typically reached through Al, who is now retired, but still has the energy to disparage anyone who steals “his designs” when they use a swamping resistor lol.

JC and Michael make valid points. I hadn’t considered that some (or many) prioritized support for the museum over possibly winning the La Scalas. I’m 65 and no longer have the disposable income for extravagant purchases - so yeah, I was in the latter camp.

Okay. Cool. I get it now. Thanks JC.

You are listed as an Officer/Trustee. How are you allowed to participate? It makes more sense to raffle them again. I wasn’t inferring anything was rigged, just that I didn’t understand the decision to buy tickets, knowing ahead of time you’re not going to keep them.

Just having a little bit of trouble understanding why someone would enter a contest for a loudspeaker they don’t want. Why not make a direct donation to the museum so someone still has a chance of owning a nice set of speakers? ¯\_(ツ)_/¯

Please use the right algorithm.

I guess if you didn’t hear anything, you didn’t win - so why care about it (which is where I’m at).

So you don’t understand Climate Change or how global warming works?

Who is “they”?

@kippy You must live in a mansion. In a typical room, the Jubilees can hit 105dB with 10-25wpc. Sounds like something is broken to me.

How big is your budget? 2-channel or HT? No one ever tells us how much money they have to spend.

Those are nice.

K-22 would be right for 78’s. BTW, they have a ceramic magnet, not AlNiCo. I have no idea what the DCR is. 11 ohms comes to mind. I have seen @Trey Cannon recommend the K-28 as a replacement for both the K-24 and K-22. This would boost the LF some, which isn’t necessarily a bad thing for the Heresy. At any rate, OP has original Heresys with original drivers. It’s up to him whether he fixes the network or not.

Should already be reversed on the network side.

The woofer is clearly stamped “K-22”. The midrange is the Atlas K-55-V with original K-77 tweeters. The correct network for these parts is the Type E. The Type E2 was for the K-24, 4 ohm woofer. The Type E2 used a 4mH low pass coil with a 33uF shunt cap. Polarity for the midrange and tweeter was reversed.
