[Vintage audiophile equipment]

I ran across a few items in an estate sale - all new in the box.  Not sure why the guy who owned these bought them and never used them.  I have no personal use for them myself, but I might get them anyway to sell.  Before I put them on eBay, would anyone here have any interest?

Any interest?

[Restoring Heresey I]

Since the consensus is to get original drivers I found a K-22 driver that I just ordered.  I'm going to put that in and get new caps as well.  I've already bought new grill cloth from Crites so that's pristine. I'm In the in Pro AV industry (not consumer) so I have the tools to create a spectrum analysis.  I'll capture the frequency response of each speaker and have that available when I sell them.  Thanks again for the input.

TS - Thanks for the comments.  So to sell in the $500 range it would need to have the K-22 drivers?  If so, would a re-cone of the driver I have be better or finding a K-22 on eBay?

I did strip them down and refinish.  Why do you say the cabinets look rough?  I wouldn't want to sell with mismatched drivers either.  My question was if it would be better to find another K-22 or replace it with the 2nd new driver - thus making replacing them with Crite woofers unnecessary.  I've listened to them for a couple of days and considered refreshing the crossovers, but the highs sound crisp and sharp.  I didn't measure the response with a calibration mic, but from listening I don't think new crossovers would be needed.

 

I've seen Heresys on eBay in the $500-$600 range, so that's what I wanted to get for these.  What would be the best way to get them to  be able to sell in the $500 range?  1) Another K-22 or 2) replace K-22 with new "clone" woofer?

[Restoring Heresey I]

I bought a pair of Heresy I's from an estate sale recently. I already have a pair of Heresy II's and KG4's so my purpose was to restore these and sell them. They weren't taken care of all that well and even had stickers on them it looked like they had been used in a mechanic's shop and the stickers made them look like something from NASCAR.  The grill cloths were ripped in a couple of places and one of the emblems were missing.  I was able to use goo be gone and get the stickers off cleanly, some light sanding and stain cleaned up the wood nicely.  I was able to get new grill cloth from Bob Crite and an emblem from eBay, so cosmetically they are great now.

 

One of the drivers had a small puncture and a rip in the surround.  (pic attached)  My thought was to 1) re-cone, 2) find a user driver on eBay or elsewhere, 3) Use a new Crite woofer or 4) search the internet for a K-22 "clone" that would work in it's place.  Option 1 was seriously considered, used drivers were tough to find and somewhat costly compared to what I had spent already, the Crite woofers were incredibly expensive.  So I ended up searching dozens of sites that sold raw drivers and eventually found one that was virtually an exact match. 

 

I found the T/S parameters for the K-22 as follows:

NomZ=8 Ohm
Re=6.9 Ohm
Le=1 mH
Qms=5.3
Qes=0.446
Qts=0.411
Fres=35 Hz
Cms=359 uM/N
Mms=57.6 Grams
BL= 14 TM
Sd=.053 square meters = 62 Sq Inches
Vas= 143 Liters = 5.05 CuFt
Xmax= 4mm
Pmax= 100Watts
SPL=93 dB @ 2.83V

 

 

The driver I found has T/S as follows:

• Sensitivity: 96dB (W/M)
• Impedance: 8ohm
• Re: 7.2ohm
• Le: 1.213mH
• Frequency response:
• 48Hz~3KHz
• Fs: 48Hz
• Qts: 0.39
• Qes: 0.428
• Qms: 4.5
• Vas: 94.5 liters
• Xmax: 7mm
• Overall frame diameter: 12.28"
• Required cutout: 11.06"
• Mounting depth: 5.00"

This was as close of a match as I could find with any driver and the price was definitely right.  I bought the driver to replace the one that was damaged.  I installed it and the sound was great.  But - here is the point of this post...........since my place is to sell the speakers, how does mis-matched drivers affect the value?  If I were to keep the speakers, I would replace the K-22 with the new driver because personally I thought it sounded better.  But to the person that would buy a vintage Hesesy, would having non-Klipsch drivers severely affect the value?  What should I do to maximize the resale value?

 

I've attached pics.  The black driver is the new one and the grey driver is the original K-22.
