Re: Another subwoofer GTG, Southern Style

I went to the Danley site to read up on the TH50. Interesting!

So even if the TH50 was down 7-10db between 20 and 30Hz, it still had more output down low than the sealed 18s when playing program material?

Re: Another subwoofer GTG, Southern Style

The TH50 is basically flat to about 22hz in Danleys measurements and had a 20hz HPF used with it. Yes above 20hz it's output is tremendous.

Re: Another subwoofer GTG, Southern Style

Listening to the 50 alone has made me want more bass. In doing this I will probably need all my audio upgraded, but I at least want one more sub.

Oops. I was looking at the wrong curve. Those two shades of green are so close.

Re: Another subwoofer GTG, Southern Style

How did the Shiva-X play the Bass I Love You song? Like, did it have quite a bit of bass?

Thanks

It did pretty well. It obviously didn't hit the dB levels the larger subs did, but it did perform. With the tuning at about 22 hz, the low 16 and 7 hz tones were below what it was designed for, but at levels we had it playing it didn't overdo itself.

Re: Another subwoofer GTG, Southern Style

I'll just echo what Brandon said because he summed it up pretty well. The Shiva was impressive and had good output with that track but was obviously outgunned by the more powerful subs there and was missing the lowest notes due to the 22hz tune and the 20hz HPF.

LMS 18
$1900 (driver, beefy amp, box, hardware, cords, EQ, etc) sealed 18", 21.5 x 21.5 x 21.5", or about 6.2 cu ft external.

I won't say too much here because it's mine. No HPF was used. I pushed it up to where it was driven very hard on the THX trailer, but was still ok and then let it rip with the 8002 bridged. It ran through everything with no further adjustment needed. It was dimpling the surround a bit on Bass I Love You (16hz). Uneventful other than that. I thought it had the best pure sound of all of the subs.

XXX 18
$1900 (driver, beefy amp, box, hardware, cords, EQ, etc) sealed 18", 24.5x 24.5x 36" or about 12.5cu ft external

This one was mine as well so I won't post much. Similar to the LMS, I used the THX trailer and set it to where it was ok with that but being pushed very hard. No HPF, bridged 8002. On Bass I Love You, the excursion got out to the "outer limits" (16hz, 7hz) it ran through everything else easily. The most sub 25hz bass of the day up till then IMO. Sounded similar to the LMS (very good) on the music with a tad less punch and extension up top (music) but more reach and headroom down low (HT). Probably the highest output levels of the day up to that point.
I am disappointed you had to be modest, cuz those were the two I most hoped to hear in grave detail.

At any rate, I think these GTGs is a wonderful idea, I thank you all for your information and hope you all had a great time.

After experimenting with different tunings with my LLT in-car, I retuned to 18Hz rather than 15.5Hz because of Bass I Love You, as I was told it was an 18Hz tone. Once I get my driver recone completed and run a sweep to test tuning, I'm going to once again cut the port out and redo it back to 15.5Hz! Steve Callas gave me a little guff over my Bass I Love You excursion vid, but that's OK... Steve, YES! I thoroughly enjoy it! Thank you very much. hahahaha. At any rate, I now have to find that THX track, and re-look for Bass Mekanik: Toccata and Fugue‏ as I always searched as "Toccata in B" and just couldn't find it...oops.

Thank you guys so much!

btw, pics link didn't work for me...

thank you! I got a LOT out of this thread, it is really appreciated. wish I couldda been there. BTW, how were the tones in "Bass I Love You" determined? reason I ask, is I have run and rerun my math on an old enclosure, it should be tuned to 15Hz but it had more excursion on the 16Hz or 18Hz tone than it did on the 25Hz and 30Hz tones. NO leaks, everything is sound.

Thanks again.
