Sonic Barrier BlackHole in my SDA 1C's

george daniel

I'll just say this,, my 1C's sound like a much larger speaker,(SDA)

Good, I don't feel bad anymore.

Don't I feel the same way with my 1C's....

Dredging up this old thread i am under the impression that if i put BH5 just behind the Mids and tweets on the upper 2/3 of 2.3tl's i will see improvement.Staying away from the bottom 1/3 at the PR is recommended.
I would also replace the batting in the upper end as well?

IMO that is the only way to place it, just behind the mids and tweeters the clarity in the highs is fantastic!! Don't do the whole cabinet!!!

brgman

Great.Thanks!

Larry, if I remember correctly, you said that the Sonic Barrier Blackhole was better suited in your 1.2TL's? I don't remember where I read that a while back, but could you let me know if this is correct? That the Blackhole material was better siuted in your bigger 1.2TL's than the 1C's (due to the size of the speakers)?

Greg

P.S. I just read the thread and realised that it is not as good in the bigger SDA's. Sorry for the useless post. I had it opposite.:redface:

I used the Blackhole/Sonicbarrier in my 1C's,,BH on the bottom/back--SB on the sides--still have it in them.The only thing that I've noticed other than previously stated,is that I'm able to to hear a tad better bass than before.I'll defer to Larry,since he was the first to do this,,so Larry,whats your current status and opinion with your 1C's?

I have Sonic Barrier behind and to the sides of the mids and tweeters of my SDA2's, and I was amazed at the bass response. It seemed to help with attack where the SDA2's seemed to be a bit sloppy for my taste.

I started with the barrier just on the rear of the cabinet but on a whim I decided to try the side walls up top and that made the biggest difference.

This was on SDA2b's.

On my original SDA2's the dual tweeter version, the sonic barrier choked them up. I used dynamat on them. Full coverage on the back and an x patter on the sides.

I agree. If you do the whole cabinet you'll make the speaker dead. It's best to try and not overdo things when you're modding and tweaking....but this crowd is known for overdoing it. In my CRS+ I only did the sides.

Agreed!! and I over did it IMO!! George I trimmed everything back in my 1C's and I like what I hear much better then before.. I am working on my CRS+'s now and I did what Mark did and just did the sides.

This was a costly mistake on my end, do a little at a time and go from there, it is a worth while tweek but use it sparingly..

I see PE no longer sells teh BH5.Should i pay the premium and get this from speakercity or just use sonic barrier?

Toolfan66

BH5 can be had at Sonic Craft, but Sonic Barrier works well too and is cheaper..

george daniel

Add me to the list of "overcooked",I've got to install the tweeter rings this weekend,,and I think I'm gonna remove some of the SD/BH that I so generously applied.

dorokusai

Yeah George....its easy to do and you're not alone as I only know by experience as well. You can get lost in the fact that everything MUST benefit and be better than before idea....and it just isn't that at all. There's no one here that thinks they know more than Polk BUT the knowledge base here is solid.

I read with interest your earlier posts about the improvements you were hearing, and now this. I'm thinking about doing some version of this to my 2.3TL's.

Thanks,

Fred

Fred-- actually two things--first was the bass,,(did not seem right),,I thought it was the Adcom GDA,, so I removed it from the chain,,and after some recent listening,,something just did not seem/sound right,,and after reading Larry and Mark's posts,,I think they are right,,cabinet overdone--for me the 1C's just seem a little subdued,,,and yes,,initially I thought they were GREAT,, then only over time,it seemed like they were missing some sparkle/dynamics. I'm gonna remove the SB/BH from the sides/bottom to start with and go from there.Looking back,, what appeared to be better,,was just different,, not necessarily better.

From what I've gleaned on this forum, the optimum placement is the wall directly behind the MW's and tweeters. Sidewalls, maybe. Definitely not in the area occupied by the PR.

Sounds like you and Toolforlifefan confirmed this.

Toolfan66

That is correct and the back wall behind the drivers does not need to be covered either just some nice strips works very well, and IMO none behind or around the PR..

Never behind the PR. It just kills the low-end. Learned that the hard way.

+1 I'm removing the BH behind/below the PR--I'll report back.Gotta love this hobby.

thsmith

Have not reads the entire thread but do you also remove the OEM batting when you do this?

TIA,

do you guys recommend one over the other, Black Hole vs. Sonic Barrier?

george daniel

IIRC the SB was much less expensive than the BH

dorokusai

I use Sonic Barrier on electronics instead of Dynamat and Black Hole on loudspeakers.

Where or how do you use the SB on electronics?

dorokusai

On the chassis. Top, bottom and side panels. I've been using it, along with Dynamat, as a pretty much standard tweak for every piece that I've owned or sold for years. I'm almost out of SB so I may use that reason to try the Cascade VB-2 brand next.

brgman

may have to try that.thanks:biggrin:

george daniel

Whew-- well,,I just pulled out the "barrier",,most of it anyhow,,left the barrier behind the mid-drivers,and a little on the upper sides,and I'm gonna have to admit(yep,,I'm not too big to say it),,I overdid it,,,Mark and Larry are spot on--too much,as in my case just kills it,,,what am I hearing,,more "life" to the music(no pun intended)and a much less subdued sound.Lesson learned,,more is not better.
