Top notch speakers with their own sub

I have a pair of Infinity Prelude MTS complete with subs and towers. They serve me very well, don't require too much power because they have their own powered subs. The multiple components for upper base and mid range do have their advantage, giving a rather complete sound projection. This pair of Class A speakers certain have lived up to their pedigree, but the technology is about 10 years old. What would recommend for the current technology? I am looking for a pair of full size speakers that have their own powered sub.

Due to room modal issues I think you'll find most SOTA will recommend a separate sub that allows optimal placement. The main advance in the last 10 years has been the wider acceptance of active speakers in the market. Just as multiple drivers allow for complete and even sound projection at high SPL and low distortion, tailored individual amps paried with each driver can take things to another level.

Marty,

It may work on certain soft music but an extra 12 db boost below 35 Hz is a gargantuan and scary extra amount for a poor subwoofer to put out. If you do this then I'd be extremely careful not to blow them up through excessive excursion or from burning up the voice coils.

Most 8 inch subwoofers are unlikely to play cleanly at 20 Hz or much below 35 Hz with anything more than 90 sb SPL output (which is barely audible). Below 35 Hz is really really tough territory for ANY subwoofer.

Another issure is ringing.....filters that boost will ring like a bell - as you exceed 6 db boost with a narrow high Q filter then the ringing will become progressively audible. Therefore it is best to use notch filters (sharp cuts) rather than any boost.
