You should probably run the DARO again

So I finally got to running the ARO which required me to move The elf knobs to zero. Wow! Really good stuff! Thanks so much for your input.

Why? Changing setting to L+R only results in a change in signal level.

The ARO had me adjust the ELF knob to zero in order to run. I did not realize I had adjusted ELF and so was missing some bass. Otherwise, the change in signal level has been welcome and I can adjust bass via the sats/sub knob on my cr-1.

Because it’s really easy.

Default JL Audio Fathom f113 Question

Would it be better or more importantly can you use 2 cables L/R output from the amplifier to got to the L/R inputs of the f113?



Thanks

This article below from JL Audio says that there no such a thing as stereo bass. One cable connection (mono) is all you need. The article is from March of this year and goes into lots of details about how to properly set up subwoofers. Beware that several of the points made contradict long held thoughts in the audiophile community (including the stereo bass).

I especially like the following from the article:

“Simply connecting a subwoofer to existing main speaker (or amp) terminals is the worst possible way to do this. Everything scientific and acoustic about this method is wrong, from the additive delay issues, to the back EMF of the main speakers affecting the low frequency signal. “

Default JL Audio Fathom f113 Question

Barry is no doubt very knowledgeable but these recommendations/opinions are based on his experience and knowledge of the JL Audio Subs. It seems a little over arching for him to so thoroughly diss the REL subs which I THINK are connected to the speaker terminals(???)

I now drive my f113 from the speaker terminals from my PS Audio BHK 300 mono's to a Jensen Transformers SP-2SX - 2-Channel Speaker to Line Level Converter to the JL Audio f113.

The integration of the f113 with the PSA BHK 300's is much more seamless with the transformer.

Jensen makes great transformers and it makes sense to use them in this application.

Technically Barry is 100% correct and a myriad of REL owners are very happy with their setups, so go figure.

It just shows that “sounds great” and “technically correct” are not necessarily tightly related.

Barry also wants you to close off all of the ports in your speakers, essentially changing the design. I’m not doing that.
