there will be at least 1 pair of foam core using TB W4 616s Drivers. Drivers were obtained from one of the generous Ottawa diy members during Sunday's door prize session.
there is a place in Montreal called Addison that sells speakers. Unfortunately very little information for the speakers is given.

Since we're now talking about speaker-building, perhaps i should mention that at least 3 speakers that I hope to get Mark to measure are smallish 2-way vintage bookshelf speakers that were possible candidates for a mini-econowave conversion for use in L-C-R in a HT.
fyi - I'm talking about 3 Noresco NEC-562 (Canadian product) that seem to have an 8" alnico woofer and an oval mid/tweeter driver. Possible plan is to pop the oval driver, and the hole might be pretty close to the right size for Denovo DNA-150 compression driver on EOS-8 waveguide (both from diysoundgroup, when they restock). I haven't run across much info about the NEC-562, but I'm going to suggest that this would be something like the AK miniwave of a vintage KLH.
So after we get some specs, maybe I can hit up Mark & Dave for some input.
Looking forward to the weekend!

Rework of a little fun project.
Well in the tradition of getting things done months ahead of time, I sacrificed my remaining firewood to make up a little redo of the two way horn loaded speaker I did a few years back.
I'm going out to clean up the unfinished parts now actually.🙄
Sorry to say there will not be any undried glue this time.😀
Although I may have to screw in some drivers and tweak a crossover.
Minions, I need minions.....

I'll be along shortly after lunch. I might have to borrow a few good men to help me out of the car 🙂
We're too sick, I'm not going to make it. If whoever is treasurer can send me an IM, I'll email the money we would have brought for the hall.
Well we all survived another one.
In typical Ottawa tradition we had minus 16 on the first day and minus 6 on the second.
Highlights:
Gabriel’s beautiful tube amp. Always a pleasure to listen to someone explain with reason and direction as to why choices were made in the design of a product. Again, no pictures.
Owens H baffle and horn setup was great again.
Rick brought a beautifully built pair of two ways that I forgot to photograph.
John (Mulisync) brought a set of large baffle spiral horns that again I forgot to photograph. But they sounded pretty good.
Dave's (DDF) speakers are always top flight. The Napoleons were very smooth, and the JR's(?) We listened to last were a very well worked out bit of audio excellence.
Other highlights. Owen's (OPC) massively paralleled buffer amps. Very clean sound. No pic.
Pierre's carefully tweaked system. A very clean sounding horn loaded compression driver with a 15" TAD sealed enclosure. Very well damped but not to dry. No pic.
And saving the best for last.
Pierre (PierreQuiRoule) did a very informative presentation on cartridge alignment. I learned some new things there. Very impressive Pierre. And quite a bit of time spent on practicing what he was talking about!
John (Bearberry) did a very neat presentation on all the stuff he has been working on using a laser cutter available at one of the maker type co-operatives. John has been doing enough laser cutting work that he has a great understanding on the Pros/Cons of the method, and has used his experience to great effect on his projects. A hearty chuckle on the “Maker” name assignment. Schools should put back the shops classes, or reopen the Tech/Voc schools of old.

Many thanks to the organizers. First time in a couple of years I've been able to attend. Brought a pair of speakers and a turntable. Mark tested the ZRTs and Pierre looked over the old Systemdek. Thanks guys.
Was only able to attend the Saturday but got a chance to hear some good music through some great equipment and chat with some knowledgeable people about all kinds of things audio...and not. Pierre did a great job with the turntable adjustment seminar. Looking forward to next year.
Got to get to work on a new set of speakers. Here are a few pics I took:
Not sure why, but the portrait oriented pics are compressed. Just click to see them properly.

Saturday and the evolution of speakers.
I showed up on Saturday and met the crew for the first time. Sort of like a wedding with all the new names when you guys have been hanging around for a couple of years ;-). Give me a few get togethers and I'll know names.
Friendly group (thank you) and a log cabin in a park in the middle of the suburbs. Isolated and you could blast a lot of speakers and not bother any one. The acoustics weren't ideal but what a neat place with kitchen facilities and all. The talk on setting up a turntable was interesting. I never knew one side of a record was one channel the other side the other and setting up the table properly made the difference. No wonder I like digital .
Mark showed up with some speakers I didn't get a chance to hear on Saturday but they were very much under construction. How'd they turn out?
Thanks to all involved for a good time.
