I bought some Bravox 3.5 in drivers as a buyout several months ago.

I am thinking about buying these tweeters that are on sale.

I can go with a 6liter closed box that will have a f3 of about 125hz.or a vented 6 liter tuned to 85hz with a f3 of 71 hz..This is with 2 drivers wired in parallel.To my understanding this should show a 6 ohm load and a 6db spl boost..This should bring both woofers and tweeter to 89DBs.These calculations came from winisd..I am new at this and have built 2 or 3 pairs using buy ot nsbs and such..I was thinking 2 order butterworth at 2500..Any help on box size, Xover suggestions ,and mismatches would be helpful Thanks Lee.
