t-line sub power

[memphissound]

Is there a power trade-off for going with the t-line design of a woofer? That is, in reaching down near the Fs of a speaker can it still operate under the published rating (coil rating)? If that rating is 100 watts RMS will it still operate to that level of input, or do you have to watch for other things (excursion limits, thermal limits, etc.)

peace,

Yes. There is no change in the power handling. That is dictated by the coil design in the speaker itself. With tranmission lines people have generally seen them as less efficient that bassreflex models but that will mean less sound per watt of electrical power that is put into them. It won't change the power rating. And due to being "unloaded" at low frequencies some people like a filter to limit excusion.
