http://cgi.ebay.com/ADS-335Is-CROSSOVERS-2WAY-PASSIVE-W-TWEET-LEVEL-CONTROL_W0QQitemZ5869753047QQcategoryZ79840QQcmdZViewItem.
The crossover point on these units is 2625hipass @ 12db and 2500 lopass @ 12db. There is a +3, 0 and -3db attentuation switch in the crossover for the tweeter section plus a car/demo switch for the woofer section for on/off axis listening. The crossover is a 4 ohm nominal load and can be either bi-amped, bi-wired or single wire hookup
THE DIFFERENCE BETWEEN THE 335 AND 336 IS ONLY IN THE "DEMO" CIRCUIT THAT YOU SHOULDN'T BE USING ANYWAY. IT WAS DESIGNED FOR BETTER SOUND IN A DISPLAY BOARD, USE "CAR" FOR IN THE CAR
dimensions of the unit are:
5 ¼ x 3 ½ x 1 1/16
hope that helps
