Stentorian build - Page 3

I think the designer made a cost decision on this one. The cost on these is less than a pair of decent CDs and required waveguides.

Sorry dusty shopfloor, great build log so far!!!

very nice build dusty. really looking forward to the finished products.

btw, what's your experience with titebond II? i like pl premium, but the excess glue is a pain to get rid off. does titebond ii hold up as well?

Dusty, I hope you don't mind if I hijack this thread for a bit, but you mentioned that you were interested in my mod and I know Curt is following along. So I'll like to post my proposed cabinet mod for the Stentorians here and get some feedback on how much impact it would have on the design.

Here is a quick mock-up I made in Sketch-up:



As you can see your Howitzer Build was a huge influence.

Basically my plan is to use the baffle dimensions from the Stentorians (with rounded tops), flush mounting the drivers per the instructions, but then attach that 3/4" thick baffle to a second wider baffle to produce the same effect you got with your baffle cover on the Howitzers. The problem is that this changes the baffle in ways that I know will impact the sound. I don't know enough about speaker designs to anticipate how much the sound will change or figure out how to update the crossover to compensate.

At this point I have not calculated the rest of the cabinet dimensions. if I decide to move forward with this design I know I'll have to redesign the rest of the cabinet to keep the volume the same for the three chambers.

So, anyone with design experience care to give a thumbs up/down on this change? I'm not starting this build until next year, so I'll have some time to take feedback. I am also more than willing to build the Stentorians as is, so if this design changes the sound too much please let me know.

" The problem is that this changes the baffle in ways that I know will impact the sound. I don't know enough about speaker designs to anticipate how much the sound will change or figure out how to update the crossover to compensate. "

that will work fine for most folks. if you really want to pick nits, the multiple steps around the tweeter will create diffraction points. ideally the baffle would be a smooth curve around and away from the tweeter and mids. revel salon2 and b&w 802 have decent approaches to this problem.

Me! Me! I called it first!

I know this has helped me out a lot in my builds. I dado all my panels. Then a decent amount of Tightbond Original and let the glue squeeze out an then use a finger to smooth into a bead along the seam.

If I was in the area, I would love to check them out.

thanks. i always use that trick to seal as much as i can.

i assumed that you're using auraco ply?

i've always used baltic birch (13 ply) but those are expensive.

i wonder if i should switch to auraco for less than half the price of baltic birch.

These speakers are close to the JTR Quintuples.

lol, thanks man. i built some stuff recently with aruco. just not speakers, yet.

Lol, always crackin' me up Dusty.

I bet they're pretty good speakers. Wish I could make it down though.

If you're going to give the away as a Christmas present, perhaps you could finish them to compliment the decor of whoever you're giving them to. What does the room look like?

Red Mahogany Sunburst using transtint/transfast if the arauco grain is nice enough...put your skillz to the test! Dark towards edges so ply endgrain is essentially dark.....

JSS

May I ask where did you find the Aruco around here and how much did you pay? I've looked at my local HD and Lowes and haven't found any around here before.

Do you care if the plywood edges are visible? Is laminate or veneer an option?

6 days and counting...

Great, thanks for the reply. If you wouldn't mind I would also like to drop by to hear these if just for a moment. However, I'm more interested in picking your brain on the curved cabinet builds you have done. I'm wanting to do my first curved sub cabinet and you did some great work on those Howitzers.

Although, I'm might be slightly off base because in your first post you seem to be PI, but a later post you sound like you might be just a friend of PI.

Great pics and narratives!
