What did you do to your stereo rig today?

OldmanSRS

Thanks! I read that doubling the cones quadruples the bass energy. I like symmetry and symmetry of sound in this case. One was good but I could tell where it was at times and that bugged me. A pair really hits hard, deep and tight when required.

Do you notice any drum hits/strikes that are more noticeable in stereo?

Also, when listening, do you pull them out from the wall? The ports are choked when they are up against the wall like that.

Also, do you sit with your left buttcheek lower than the right? If not, your not doing it right.

I bought this simple and unassuming looking Lumin U1 Mini from AudioThesis, and I'm amazed at how much difference a high quality streaming transport can make.

I've never heard Tidal sound this good on my system. Worth every penny.

I have it connected to my Ruby DAC via an Audioquest Forest USB cable. Would like to try a higher end USB cable with it to hear any differences.

Tidal SQ thru the Mini is very good. I’m impressed.
Before you finalize that review, try the Mini with a “higher quality” cable. I’ve not heard the AQ Forest, it may be a very fine usb for a sub hundie. I’m currently running a WW Platinum and all I can say is wow.
That said, I wonder what a Final Touch Audio usb could do for me? I’ve only heard great things about it ...

It’s all about the symmetry, isn’t it?

I'm not running stereo on the subs since the Adcom amp is driven from combining both channels in the left sub's preamp and feeding that mono signal to both channels of the Adcom which in turn feeds the driver in each sub speaker.

Downstairs in the garage I do run one stereo channel to each sub. I can't say I notice much separation. Sometimes the bass content below 40 hz contains some out of phase info that when running stereo subs mixes in your head instead of being cancelled out by making it mono first, and I can hear the results like a ghost bass image behind me but it's rare.

Not thus far. I listen pretty loud and the cones are not moving all that much. I ran a continuous 25 hz test tone through them and cranked it up until I could hear some port noise but I have yet to get them that loud with material. I will play around with distance from the wall and see if it changes their response.

Hmmm, thanks for your observations. I have my subs up on stands and at the same height with the tweeters. The signal is in stereo on a full range system. If you ever have a chance to do this? I would highly recommend it sir.

Great looking system!

I was looking at your setup and did not know those were subs on the stands. I'm sure having them inline with the tweeters helps with sound continuity. What subs are they and how much do they weigh? I was planning on running stereo subs in the main room but since I could no longer buy the HSU plate amp for the second sub, I went with dual channel mono. T he main thing my 1.2s lack is tight bass when the listening position is midway between the speakers and a rear wall. I fought this and lost in several homes. My last home had a 26 long by 14 wide room and I listened from near the rear wall. The bass was great but if I moved to midway, the bass and the punch disappears. These subs restored that and then some in my current setup.

I'm not a real high end guy or an audiophile. I just like stuff that works well enough for my taste, and to impress friends occasionally and I like to build as much of it as I can.

Dang, I just typed a long response to you and then edited it but it went away! It's too late to keep going. Signing off til tomorrow.

The subs are Rythmik F25's. As for the weight? Good question. They are heavy. Definitely a two person lift onto the stands. Once they are on? I simply twist them to make adjustments...although not easy given the space restraints.

Even full range speakers could use subs IMO/IME.

Although I am a KISS (Keep it simple stupid) kinda guy, the subs round out the system as a whole and offer yet another level of (in spades) listening enjoyment. When in stereo, the sound stage is at an even higher level of enjoyment/playback realism.

It can offer you pinpoint reproductive efforts with so many things other than the drums. With the drums, it can offer you pinpoint locationality cues to where one can point a laser at each individual component within the drum set and/or sound stage.

Trust me when I say that I have been there, done that. The guys on this forum have given me grief about it as well. It happens. TTY tomorrow.

Sending my Nordost Heimdalls out to be re-terminated from bi-wire to shotguns on Monday. But I will use a set of Canare 4S11 or whatever they are...

Wipe them down with antiseptic wipes and bleach first. You don't know where they've been.

Not a dang thing wrong with Canare wire.
I just happen to use a dual run to each speaker of 4S11. I can thank Frank at Signal cable for the idea. Is 8 gauge cable overkill???
Nope!

Good for you! I'll have to plan a little road trip this Summer. I'd love to get ears on a pair.

steveinaz

Very cool...get busy we want to see them!

displayname

Very exciting! I'm jealous, but hopefully at some point I'll snag a pair. Walnut would be my color of choice as well

I found there's a lot more to speaker cables than gauge when I tried a double run of Canare wire.
I had to try it and see for myself though

Is your Canare 4S11 10 gauge, too? That would make a double run equal to 7 ga? Specifically, what did you learn...? I’m gonna dodge a tomato or two before this is over.

IME doing internal speaker mods, one channel’s speaker at a time; (more recently) bit by bit, progressing towards bi-amping*, size made an undeniable diff especially in the lower octaves. In the case of Polk speakers of ~12 years ago I’m certain that’s due to their wimpy internal wire. Jess says it’s 16 ga. I say 18.
*and eventually tri-amping

https://forum.polkaudio.com/discussion/174880/tri-amped-rti-a7#latest

Upgrading the internal wire to 12 ga of my CC made most male dialogue heavier* and/or thicker*. Further, after I removed the passive XO filtering I upgraded to Canare 4S11 inside and out. More so* than before, I felt forced to make light use of my CC’s EXO’s PEQ capability to rebalance its tone.

I hope this helps you to understand why I must chime in anytime someone attempts to downplay the value of wire gauge. I realize gauge increases doesn’t always apply. If it didn’t make a diff, I’m sorry, but you won’t know till you try.

Sorry for the long winded rant. Tony
