Dayton Audio ND90-8 3-1/2" Aluminum Cone Full-Range Driver 8 Ohm
Hey Matt, quick question. If I'm planing on using these as full range speakers with a sub and crossing them over at 80hz, should I tune the enclosure to 80hz or what would you suggest? Much appreciated, have a good one.
You can tune anywhere between 60 and 80 Hz and have a similar effect on excursion performance above 80 Hz, so it will not matter much.

In B&O CX 100 enclosures I was hoping to run two ND90-8(each ) in parallel with AMT mini 8. If I use the Dayton XO2-2.5k will that bring the Xover frequency to 5000? Problems with this set-up? The drivers all fit these quirky but beautiful little boxes.
Using this tweeter which is 8 ohms and wiring the woofers in parallel to a 4 ohm load would still be a 2.5k load. You would be better off with a XO2-4.5k as it will be better for the tweeter

I dont know much about bracing but do you have any simple suggestion i could implement on my boombox?
Bracing isn't an exact science, using scraps or small dowels to join the larger sides of the enclosure together is all that is required.

what is the size of the spade terminals I should buy to go with this driver?
This driver uses a 3/16" and 0.110" terminal.

I want to use two of these speakers to make a portable speaker. I was wondering what volume or dimensions i should make the enclosure and should I separate the drivers by putting a divider in the middle? this willl be ported
I would recommend an enclosure with external dimensions of 6"H x 17"W x 8"D using 1/2" thick material. Two 1" diameter, 4" long ports will tune the enclosure to about 50 Hz. This is assuming two speakers per enclosure. You do not have to add a divider, but a brace or two can't hurt.

Can you wire one of theses speakers directly to a amp without anything between it. But have it crossed over on the amp at 80z with a sub? Or will it sound bad at higher frequencys?
These can be used full range without a problem and a high pass at 80 Hz is recommended if you have a subwoofer.
