Center channel
Howdy,
I was looking over the plans for the FH3 and FH3 Lite and noticed that there aren't any plans for a center channel speaker on the Lite plans (or XL for that matter). Have any ever been drawn up? I'm considering a 5.1 home theater set up and would likely use the Lites due to space limitations. And perhaps just the stock enclosure for the surrounds. Any thoughts or suggestions?? Most likely go with the Fostex FF85WK since I already have a pair of those drivers.

Thanks Dave,
I've seen the miniOnken plans on one of your websites, are those what you are referring to? The center channel speakers on the FH3 plans all have a more rectangular (and in landscape mode) enclosure, all of the Onkens I saw were more of a traditional (portrait) format. The driver I'm most interested in at this point is the FF85WK.

Depends on how loud he likes to listen, and his room.
And most amps that size are SE tube amps and the output impedance can affect performance (ie an FE126 really wants one, mpst pf the Alairs don’t care so much.
More info?
dave
So the alpairs will be fine, although perhaps not quite as loud as the Fostex? I believe he is talking about an amp with 8ohms output impedance. He was showing me the plans and talking about power transformers. Not sure what you mean about the Alpairs not caring and the FE126 wanting one. One what??

Yes. About 4 dB. The FE126 will sound like he has 2 x the power. But with the FE126 it is much harder to get bass (even with the aforementioned hiOutputR amp.
The 8Ω he said is the nominal speaker impedance and is related to the OPT. OutputR is a different thing.
I am working on a tutorialish thing on amps in “The Fringe”. A teaser.
Your guys amp probably falls into the same range as the ACA. Anyone in, or near the fringe needs to start to think about how the speaker impedance interacts with the higher output impedance of the amplifier.

I think Dave was referring to amplifiers with a relatively high output impedance, like single ended tube amps.
Ok, you beat me by 6 minutes.

Hi Dave,
Are you saying that this center channel is a miniOnken design? And if so, do you have drawings somewhere for one using the FF885WK?
Thanks,
Bob

It's not super awesome, but it is effective for keeping the dog off the driver cone. It's an 8" woofer protector that I stuck on the front baffle with some 3M Command Strips that I cut to make them a little more narrow. I couldn't bring myself to drill holes in the hardwood baffle...

driver clarification
Ok, I'm in the process of acquiring the flat packs, Thanks Bob! I'm confused, is the Alpair 10.3, the same as the Alpair 10M? I'll be running these with a 15W Son Of Zen. I have a pair of Alpair 10.2 that have been sitting in a box that I had planned on putting into the Pensil 10.2, haven't put that together yet. I've read here that those should be ok for the FHXL....any thoughts on a driver selection with the SOZ?

Yes, it is a miniOnken, I checked, no i have not done the FF85wk one. It will be the same as the one for the A5.2 but with different venting & driver mounting details.
I will get onto getting a finished drawing done.
dave
Yes. Officially Alpair 10.3a (a for arrester). Your amp should be fine)
A10.2 will fit into the same cutout and work well in FHXL.
