Audioengine A5+ and AS8

post #1 of 5
Thread Starter 
Hi,

I'm trying to achieve a setup where the sub handles virtually all lower-end frequencies and the A5+ just focuses on the upper mids and highs. My setup is a PC optical out into a DAC. DAC analog out into the A5+ inputs. A5+ varibale audio out to the AS8 inputs.

The problem is despite setting crossover at 130 the A5+ are still outputting low-end frequencies and I'm getting a "double bass" effect. I verified that the A5+ was still playing low-end frequencies by setting the xover at 130 and turning the volume completely down on the sub, instead of hearing thinner sound from the A5+, I heard the full range. Checking the xover section on page 6 of the AS8 manual it should not behave like this. Any idea why the A5+ continues to play the full range. Do I need a receiver to manage bass? I thought the sub would handle it.

I also tried an alternate connection method with the same result (A5+ continues to play full range). For this connection I tried PC Optical out to DAC. DAC analog out to the AS8 inputs and AS8 outputs to A5+ inputs.



Thanks

You might want to contact the people who made the product you bought.

Yep, have an email into them... I'm hoping to hear from anyone who may have an identical setup..

The A5+'s internal crossover doesn't have a low frequency cut off and will play full range if given any chance, but im sharing your pain bro, it would be great if they did. The best i can figure is to have one line running to the A5+, set your crossover for them AND then run a separate line for the sub.

You need a electronic crossover like a Behringer DCX 2496.

The problem is that the most economical way to get such a thing seems to be by obtaining a low end AVR.

The practical and economic aspects of that solution aren't so good.

You end up buying a lot of hardware you bought the AE speakers to avoid.

Someone needs to make a box that is the DSP and inputs of an AVR with line outputs and no power amps. Trouble is, doing that for less money than a low end AVR is probably mission impossible.

Welcome to the wonderful world of economies of scale!
