Good call tigerwoodKhorns!!! 👏 I have worn Thorlo socks for over 40 years, best socks ever. 😎

Congrats from me as well Rich. I am running the same system, but actively (XP-4080) and with K-691 and can strongly echo Rich's description on how this set up can sound. Prior to this I had my DIY Tigerwood Jub-likes and can say that the Peavey/402 combo is not a huge distance behind the Jubilee. And also congrats to the new owner, who I am sure will be very happy!!!

I kind of like these ones better... https://www.canuckaudiomart.com/details/649711241-very-rare-set-of-belle-klipsch-speakers-100-all-original/ No affil.

You know you have a problem when... My name is Sancho Panza, and I am a Klipschaholic. 😉 Congrats on the them speaks!

I would bet that it is like MM said, loose crossover board or one of the components on the board. Years ago I had a PMC speaker with a similar symptom and we tracked it down to a capacitor that was loose on the Xover. The really strange thing about this... lately all the buzz has been on the new Heresy IVs. 🤨

Parts Express says that the UM18-22 18" Ultimax can be used for both sealed and vented enclosures. Not the 18in, but for the 15in, Bill Fitzmaurice recommends it as the premium driver for his 24 inch Tuba... "The RSS 390-HF-4 lacks a gasket on the front of the frame, so if you order it get speaker gasket tape as well. An inexpensive choice is the Dayton DCS 385-4, a premium driver is the Ultimax 15." I was going to go with the Ultimax 15 for the empty Tuba TH that I just bought, but they are out of stock, as was the RSS 390-HF. Solen had one RSS 390-HF in stock, so I went with it.

I should have also suggested CDT Audio. CDT is what I went with in my old Civic back in 2006, my front doors had 6.75in for the OEM front for speakers so I replaced them with ES-062 Braxial. https://www.cdtaudio.com/braxials/braxials/es062brax.php These were a very nice sounding speaker! After looking closer at the 2005 Camry I see that it did use 6x9s in the front doors, this could be a very nice drop in replacement... https://www.cdtaudio.com/coaxials/es0691cfx.php

I would suggest reading... For example, line 7 of the original post.

I agree Carl, but that is what Dynamat and a volume control with a big amp are for... to drown out those pesky noises. 😎

It has been a while since I did any aftermarket car HiFi, 2006 Honda Civic. My last 2 cars have been top trim level VW Golf and GTI, no need for aftermarket stereo in these, the Fender systems are fantastic! But, back to my Civic era. I would suggest doing the front speakers first and if you get good speakers from either Focal or MB Quarts (both top tier, at least use to be). Rear speakers would be unnecessary, other than ambient fill. 6x9s were more for old school North American cars with huge rear decks when we all thought music should come from the rear of the car. IMHO, music should come from in front of you, just as we typically listen to our home 2 channel systems. With a good speaker from either of the 2 brands I mention and a good installation, you should get a beautiful wide, full soundstage from the top of your windshield to your knees.

Yes it was a lot of driving, but I turned it into a weekend away at my college buddy's family cottage up in the Laurentian Mountains. Eating, drinking, and comparing the HIPs to his Altec Model 14s. We all agreed that the HIPs bettered the Altecs. 😎

I happened across a very nice pair 2 years ago on Canuck Audio, the very first day they were listed and jumped on them. The only down side was I had to drive to Montreal to pick them up, about 7 hours one way for me. Glad I did! https://www.canuckaudiomart.com/details/649496667-klipsch-heresy-hip-1979-1980/

junior, You could maybe consider applying some paper backed Walnut veneer, for a "real" Walnut look. I use Heatlock glue with a common household cloths iron. https://www.veneersupplies.com/products/Better-Bond-Heat-Lock-Veneer-Glue.html It really is not that difficult and when finished with Rubio Monocoat Oil Plus 2C (pics below are the "Pure" color), looks outstanding! https://www.rubiomonocoatusa.com/collections/oil-plus-2c/products/oil-plus-2c-350ml

Even thought I have had 4: LAB12 drivers sitting here waiting for me to build a quad of the LAB12 TH that Claude has recommended, I picked up this guy. 24in Tuba HT... The seller pulled the driver for another subwoofer project, so I ordered a RSS390HF-4 to plug into this beast. I will be interested to compare it to my F-20 that sits in the back corner of this room, with the same RSS390HF-4 driver.

And in more recent times... 5400 ES-SACD.
