Nope, Clarion didn't make stand-out speakers back then. Their comp sets were decent, their subs were mediocre. Clarion's claim to fame back in the 90's was electronics. They made some of the best h/u's, made solid amps EQ's and crossovers. I ran Clarion decks back then, but wasn't at all interested in their speakers. I still have a Clarion deck from mid to late 90's that I keep around as a back up deck, Id put its sonic performance up against almost any new school deck these days.
Oldschool versus newschool speakers. Seems this topic has come up a lot lately around here. And I keep reminding people that Hoffman's Iron Law plays a large role in why sensitivity of subs has changed so much in the past decade or two. With watts getting so much cheaper, its a natural progression that speakers will become less sensitive. Cars are getting smaller every day, so enclosure space is getting more and more valuable, while watts get cheaper. So again looking at HIL, if watts get cheaper while space available gets more valuable, the only reasonable expectation is that manufacturers will build less efficient subs that work well in smaller enclosures.
But that's only talking about subs, not comp sets or mids, midbass and tweeters. There are plenty of highly sensitive speakers on the market today. Sure there are more high power handling comp sets than there use to be, mostly due to the price of watts going down, but not all of that power increase is by making heavier, clumsier mids. Cooling potential has gone up a lot by using things like better frames (cast alum versus stamped steel), higher excursion potential (pumps more air through the motor), and more sophisticated motor designs that concentrate on improving cooling.
MTX amps were solid back then. The Thunder series were quite popular and performed well.
The Kicker Solobaric was the first sub I ever saw that was designed and marketed to work in small boxes (was their claim to fame when they were new). It was the first step towards the lower efficiency, smaller enclosure using subwoofers that we now see so commonly. Yes, they sounded good too, especially for their day. But Im from the school of thought that newer subs have some pretty exciting new technology on them that subs of that era simply didnt have access to. More advanced motors that improve cooling, lower distortion (BL optimization most notably) and increased displacement potential (higher xmax). Its pretty easy to find a sub these days that can outperform an original solobaric. Even by today's standards they were/are a solid performer, but not a stand-out performer, and certainly no where near the top of the performance list.
Long story short, my dad keeps talking about how he had S10 with 2 6.5 Clarion Coaxials in each door (not sure which series) with matching 6x9s and a 12" Kicker Solobaric custom built into the center console firing at the windshield. All run on a MtX 4 channel and mtx monoblock He claims that as far as clarity, this setup murders any of mine. So my question is were there some Clarion speakers back around early 90s to mid 90s that were amazing or something? I've heard the latest Clarion stuff and its ok, but not GREAT. and were the old school mtx amps the ish?
You cant compare two system like that, especially when one no longer exists to reference, and only discuss brands being used. If his system really did 'murder' yours, it wasn't from the brands being used, it was from the install. If yours gets murdered, or actually murders his, its from the install. You both appear to have/had solid equipment, and imo its obvious that the biggest room for improvement (or failure) was in the install.
Your dad's install had some things going for it, and some potential problems, if Im going to judge only by the very brief description about it that you gave us here. First, small vehicle (S-10). Its tough to fit a 3-way in an S-10 and get everything right. They are small, not a lot of leg room. And, we dont know how your dad's front stage was mounted. Did he use the stock dash locations, firing up at the windshield, for his tweeters? If so, not a good sign. Did he use kick panels? Was his 3-way run active, with the 6x9's running as dedicated midbass? Or were the 6x9's another fullrange driver? The center console, assuming it was built well, it still lends itself to the concern over motor noise.
Id also have some similar questions about your install. I dont know the vehicle, I dont know how your power/xover network is set up, and I dont know how you've mounted the speakers in your front stage. I will say this though, you posses good enough equipment that if your install was done well, and his done not as well, you should have no problem competing against the sonic performance of his setup.
Convince dad to put his money where his mouth is, and build a new system that will 'murder' yours. Invite him to join ca.com too if you want. There's still some of us oldschool guys around that will be able to relate to his memory of what car audio use to be.
Cheers.
