I use Room EQ Wizard's sine wave generator. Works great.
Use a voltmeter across the amp's positive and negative to monitor voltage going in. 15V is really the most I would suggest... it will be over 100dB at one meter by then, and probably rattling a few things. It amounts to about 25 watts or so.
The reason I suggest 16Hz is because this is at an excursion minima... if the drivers aren't moving much, and stuff in the building isn't rattling much, you will easily hear the chuffing sounds from any leaks.
200W should push these pretty good already... I'd wait and see if you even need a bigger amp.
