Well i get the impression either the RMX1850HD or PLX1602 is the way to go since i dont want to have to mod my amp rack for extra cooling.
There are a couple of things im still not clear on however. A no. of posts are telling me 1600W is not enough for subs, doesnt that depend on the sub?! Apart from this im going to be running this amp real hard as it will be used occasionally for a drum and bass night. If im exceeding the long term capabilities of my drivers im surely not going to get more sound because of power compression and probably running the risk of voice coil failure?
Also isnt running at 2400W compared to 1600W only an inaudible 1.5dB rise or are the equal loudness curves having some effect here?
OR will the music still have enough peaks (even when run through LMS compression) to stop full sine power getting through?
Excursion is not an issue here, the drivers are only pushing 20mm max at 750W with a >30mm max. This figure should be even lower with a steep rolloff just above this point.
Sorry to ramble on again but i want to get this as right as right can be!
Thanks to all who have lent their advice and shared the knowhow, its much appreciated!!
