So... After getting a mic and screwing around with REW... 1. Here is the stock crossover with damping mods and the goldwood midrange: I am not sure why the top end waterfalls off a cliff at >4.5khz 2. Here's the same mods with a cheapo crossover: Almost 10Db down 2-5kHz...

So, hypothetically... if we were looking at the 15" woofer for replacement... there seem to be a bewildering array of options. The first thing that jumps off the page about the stated speaker specs is the overall 95dB sensitivity. I tried to match the midrange (Goldwood 85/8 @ 96dB) to this...

That looks more appropriate!! Thanks!

The adventure continues... After modifying the second speaker, I added the damping and the cosmetic "upgrades", and spending some time listening, the OE Xover is much better than the cheepos. Hands down. The cheapo is "thin" sounding, it's losing a lot of midrange and bass, and just inferior...

Next steps are in the books… here’s some shots of the stock cabinet. Polyester fill. Empty cab with the blanket removed, look at your glorious bracing!! That tweeter… And a few progress shots of my damping build, also did a midrange replacement, but no xover mods. (Yet) Happy to teak a...

Thanks again. If the mid and tweeter are fighting one another, my stuff isn't going to fix that! On the crossover side, I went ahead and got some Dayton poly capacitors, and will swap those onto the original xover, and give it a listen. Hoping for, but not expecting miracles. Hoping to get...

Thanks for the response. Replacing the midrange was sort of a response to the badness I interpreted in your graphs at 1 & 2kHz, as was adding the slight tilt (if badness happens off-axis - change the axis), as well as some negative stuff that Dennis Murphy had said about the mid. That, and at...

Thanks. Based on the cap ratings (2.2, 10, 17uf), I am trying to guess at the crossover points for the Bic. The 8ohm chart I am using me is giving me... strange frequency values. Clearly I am missing something. Or everything. Maybe 4500 & around 560?

Your secrets are safe with me. So... pushing deeper into the rabbit hole. I Identify 3 capacitors on the stocker: 1) 10uf, looks like a Dayton 10uf goes around $9 2) 17uf, Dayton for $8 (why is this physically smaller than the 10uf??) 3) MET 225J? Looking this up, it sounds like its a small...

Thinking more about your comment - I would think that 850hz is way high for that 15" woofer. Like you, I don't know what the crossover points are for the stockers - since my new midrange is published with a lower range of 500hz, I wonder how that factors into that low end and will play with...

Thanks Severian! I suspect you are right. I saw some interesting 3-way crossovers (not bi-ampable) on Parts Express, but was reluctant to throw Dayton money at it.... At $26 for 2 cheapos, I was willing to take a chance. Comparing the OE and cheapo, there are more bits and pieces on el...

Well, I did a thing. I took one of the pair of beasts apart, put damping in the cabinet, replaced the crossover and the body of the horn, and tilted the cabinet back a few degrees. Then I spent the next several days switching L/R (to the annoyance of the SO and amusement of my kids). Left...

Those look sparkly! What are they?

Cool thread, fellas. Thanks for all of your thought and work. I've had these speakers for 5+ years now, powering them with an Adcom GFA 5400 and an NAD reciever as a straight 2 channel (music only) in a huge room with 25 foot ceilings. Got the speakers off Craigslist for around $200 for the...
