The SAX would be a good match with the 60s. Also looking to MB QUART and memphis for a good multi channel amp. If your on a budget that is. Power Reference by memphis is a great series.
just placed my two in a 4th order designed by xander crews. on 200rms these things are loud and clear. for 32 bucks shipped for the pair i couldnt beat it.
600 rms is a lil too much for these IN MY MIND. some ppl depending on box design can run a little more to these but you only need to put 300-400 rms to these to make them reach xmax. some people would argue with me but i like my equipment to last? just saying
ok so i jumped on a calc really quick. its gonna be hard as hell to do a slot port depending on the freq. i could only get it down to 51hz safely. with enough port area. your best bet is to do aero ports.... i have a decent box drawn up for you that will fit. its tuned to 43hz. with 1.8cuft...
theres a difference with the internals but i cant remember what changes were made. the newer models you can drop to .25ohm with no problem. i just cant remember the change
