Yorkville / L&M drivers: any worth using?

I'm thinking of making a few econowave-style PA cabinets.

The affordable drivers most people have discussed to death are not as easy to get up here.

But there are a few drivers stocked at Long&McQuade (Canada's biggest chain music store) as replacements for their popular "Yorkville" speaker line.

Sadly, it's not as simple as picking out a favourite Yorkville design and buying CD/Horn/Woofer. But the drivers listed here look like they might have some potential for budget Econowave-style designs:

Of particular interest:
CDs:

B&C DE750 (not currently working on anything nice enough to justify a 2" CD, but it's nice knowing it's available to pick up locally for half the price of anything like this at Solen or Qcomponents)

Celestion CDX1-1410
$52 for 8 Ohm / 40 Watts Program / 104dB
Haven't seen this anywhere else, and I'm not sure if Celestion part numbers mean anything.

CDX1-1070
$43 for 1" exit, petp diaphragm,
8 ohm/ "24W" / 106 dB
Recommended min. crossover: 2200Hz
Seems very similar to the 1445, which is about the same price if you aren't counting shipping cost. Around half the price of the cdx1-1415 with aluminum diaphragm.

Woofers:

Eminence 122669 / Yorkville 7312
$200 on sale
8Ω 900WPGM 3"V.C. neo speaker


Eminence model - 121427C / Yorkville 7288
$120
- 4 Ohm / 100 Watts Program Power
no other specs


EMINENCE 151845B / Yorkville 7336
15" / 8ohm / "225 Watts Program Power / 550 Watts Peak Power"


Anyone know anything about any of these drivers? Any way to decode the part numbers and get more specs?

I'm considering buying a few of the 1" Celestions to replace piezo tweeters in some older PA boxes.
 
Any way to decode the part numbers and get more specs?
Contact Eminence support via email, provide them with numbers starting with "67-xxxxx" from the stickers shown in the L&M pictures, request help to ID the driver. They'll help you identify the exact speaker or even better, email you the drivers specifications.
I haven't contacted them in a while but they were very helpful in the past.

The "Eminence 122669 / Yorkville 7312 $200 on sale" might be the KappaLITE 3012LF 12" .... if so, very good value in Canadian dollars!
