LM3886 parallel output resistors - Page 2

That's EXACTLY why I'm interested in these.

To use with an active system.

Audio is so full of contradiction, that I get distracted, and the past few days I've been thinking of building one of these 4" full range speakers systems (Fostex 127e in a vented box -- I'm sure you've seen the "hoopla").

I have a subwoofer and listen at low volume levels anymore, so it may be worth trying -- if I like it I may skip my active plans for now.

But I don't know -- the original plan was to use the sub and an MTM speaker which setup the need for (1) mixed mono sub amp with 2 LM3886 in parallel (1)
stereo LM3886 for the low/mid (probably not enough power) and (1) stereo LM3886 for the tweeters.

I have a USB preamp already built and thought I'd add the crossover to the board with maybe a simple jumper system on the board itself for crossover points.

I've been wanting to do something that in theory is a vast improvement over conventional passive crossovers and "a stereo amp".

Have you ever heard the 4" full range speakers in a bigger box?

I must admit when they are used in near field monitors they sound incredible.
