Mystery Frazier Mark V Speakers

After reading numerous posts here, there, everywhere, and asking everyone I know on Facebook, I've decided to join your forum in hopes to find some answers.
I recently came upon a pair of what appear to be some form of Frazier Mark V speakers in ok condition. The cabinets are actually very well build, solid and sealed. I haven't found any particular method to get into them other than removing some of the speakers from the cabinet. They are a medium wood and very heavy. I don't have the dimensions handy, but will measure when I get home.
The drivers consist of a 12" sub, 4.5" mid and a 2.5" tweeter (if memory of the last time I measured is correct). I could be wrong, again I'll double check later. There is a "High Frequency Driver" pot in the upper left, as well as what I believe is the only port, a 3" port with a round honeycomb (black) grill over it.
The backsides have your standard "one touch" speaker wire inputs.
The grills are black fabric and each has a square badge with "MARK V" (with the "V" under "Mark".

So my question is: What version are these? Are they really Frazier Mark Vs? Does anyone have a schematic of the cross over in case I need to rebuild it?

I am going to do my best to insert pictures. It's been forever since I have done this so bear with me.

Interesting, but I don't think they are original Mark Vs. Some versions had a piezo tweeter and some had a horn. You may want to check the F.U.G. (Frazier User Group in the Klipsch Forum). They have a lengthy discussion chock full of info.

Maybe post pictures of the magnets on the speakers. Part numbers can help find out a lot. also the crossovers.
 
Welcome to AK!

Ditto on checking out the crossover. Dayton caps from Parts Express are a good value too, they are actually made by Solen I believe. Metalllized polyprop are cheaper than film and foil. You can use the nonpolar electrolytics for larger values, the films get huge.

That's a woofer, not a subwoofer, by the way. Subs are typically in their own cabinet.

Have fun with em!
 
Thanks everyone. I found the "FUG" group on Facebook (they've moved there, I guess). I asked there and they say they're not Frazier speakers. Someone had a pair just like mine in Colorado and sold them on eBay as "Mark V High Frequency Driver Speakers"... which, doesn't seem like a name more a description. I also cannot find any info on that name other than the guy's eBay listing. So, I'm calling them "unknown Mark V speakers".
I actually ordered what appeared to be used (but better shape than mine) woofers off ebay. I haven't cross referenced but may be the from either the seller of the "Mark V High Frequency Driver Speakers" or the one who eventually bought them from him. It'll be an interesting project, for sure.
 
Are there any numbers stamped on the back of the drivers? That would tell you who made them and possibly when.
 
Only a thin sheat of batting in their as well. If you get them up and running, and they sound boomy adding more poly fill would help. It's looking more like White Van specials so far. And throwing that out their they still might not sound half bad. Surrounds, caps and extra stuff'n is pretty cheap and they may make for a fun project!
 
That's my worst fear.. vintage white van imitation speakers. I'm still (currently) looking to see what the heck these really are. Definitely not Boogie Mark Vs, lol. Not Fraziers. They are truly vintage. The cabinets are very well made with the exception of no access panel in the back.
 
Most of the speakers I have and have owned didn't have access on the rear. I only have two sets of speakers that open from the back. A pair of speaker kits and Wharedale W90's. Everything being stuffed from the front is pretty common.
 
Yes the Facebook page of Frazier User Group suggested they are NOT Fraziers. Bummer. However I still don't have a brand. I did get pics of the woofer driver part number and the tweeter part number. The woofer is RTR 2302 Taiwan PT-81 7923 (8 ohm)
The tweeter is part number 117036 (4 ohm) Taiwan PT 93-7850 (might be 93-7350)
 
also I don't understand why the tweeter would be 4 ohm, while the woofer is 8 ohm. I am unsure but will check later today what the mid range is.
 
Googling the PT # I'm seeing similar part number speakers used in Pioneer speakers on eBay, though Pioneer speakers were made in Japan whereas mine are Taiwan. Did "PT" stand for part number?
 
Well, I'm not seeing any of the 3-digit numbers in the big list of EIA Codes.

http://www.davelevasseur.com/old/1994 EIA Source and Date Code Book.pdf

RTR was a speaker brand made by BIC I believe, but I don't find RTR as a driver manufacturer.

Quite often drivers have numbers known only to the maker of the driver and whatever speaker manufacturer they made them for. And some of those may be date codes as well. A 4-digit date code is sometimes the year followed by the week - so 7923 and 7850 could have been made in 1979 and 1978. It's feasible for those drivers to be used in the same original speaker.

The fact that both drivers have PT-XX on them suggests they were made by the same maker even though only one says RTR. Or, the PT numbers may have been specified by the customer for their own uses, and the drivers could be from different makers.

None of this tells you who made the speaker but you might look around for a BIC or BIC America or RTR speaker with the Mark V model number.
