speaker size and crossover settings. - 12/31/12 07:36 PM

Hey all, couple quick questions.

What is actually happening when you select small or large for speaker size?! I had guessed by selecting small it would limit your crossover freq to maybe 80hz or something similar but it looks like either small or large speakers can have their crossover freq set to 40hz.

Following that, what if you don't want your Front L/R speakers to but cut off at 40hz?? I'm not saying many towers will do a whole lot below that but assuming you have something that will go lower, is there no way to have the full range passed through??

Thanks!

Typically setting the speaker size to large removes a filter to allow a full range signal to go to the affected speakers. For instance I have Klipsch RF-82 speakers with a response down to 37hz. If I set them to large in my system then they receive full range input. If I set them to small, I have to tell my system where to limit the signal to them. What I typically do is set them to small and cross them over at 40 or 60 HZ. The advantage to that is the below the crossover frequency the LFE signal is sent to the subwoofer which has its own amplifier designed to power those power hungry low frequencies. That saves a lot of power in my amp to supply to the mains which means I can play my system to its full potential without detriment to the sound or challenging the amp or speakers to play outside their designed areas.

Consider any speaker that cannot reproduce bass as well as the subwoofer as Small. When set to Small, the speaker is rolled off below that frequency and the bass is redirected to the sub. When set to Large, the speaker receives a full range signal (regardless of the crossover setting).

Set to Large.
