TTLS To Help Out TT

[osse]

Thats some crazy amount of Wood for a 8".. Thanks for the porn pics;) and very detailed build thread!

How do you think the TT sound for music?

Do you actually not think one TT is enought for home environment?

What crossover settings do you use for the TT?

I'm thinking of upgrading my music production system and is thinking of maybe sla and TT(yes I like it loud).. anyone got experience with this?

Sorry for hijacking..!

Howdy Osse!

Thanks! It is reassuring to have folks write in and let me know they are enjoying my posts. Makes the extra work of photos and posting worth it.
Yep that is a LOT of wood, but makes for one fine sounding sub!

How do you think the TT sound for music?

Just fine. For music, my mains do 95% of the sound reproduction, but the TT takes care of the rest.

Do you actually not think one TT is enought for home environment?

For my small multipurpose room (14'X 20') it probably is enough. You really can't believe how much clean bass one unit will deliver. My wife feels one is too much. I couldn't believe she would let me build another, but I have a feeling that decision is going to cost me BIG sometime in the near future.

I am trying to even out the response to get more than one sweet spot during movies. And the expletives from my buddies during movies is rewarding

What crossover settings do you use for the TT?

My amp is crossed over at 80Hz, the plate amp is crossed about the same. This took quite a bit of tweaking (along with gain level) to get rid of the bass localization issues. I'm hoping this second TT will get rid of it for good.

My only experience is with the TT, but if you start a thread with this question in the Home Music/Theater Area, you may get more answers. Good luck!

Hijack? I don't see no hijack!

I just recently joined, really enjoyed this thread, nice work Dave and thank you very much for the pics.

[NCDaveD]

Thanks Benjammin! I'm glad that you have enjoyed my journey.

It is liable to be a couple of days before I can get the TTLS up stairs as I messed up my back the first week of January, and I have to be REAL careful of what I lift and how I lift it. The wife isn't too interested in helping out with this, so I may have to bribe the neighbors teenage son to help out.

If you let him listen to it he will get one somehow and you'll never have peace again...you've been warned!

Smart looking paint job BTW.

Great Build Thread NCDaveD Very informative and most importantly honest. I find learning of others mistakes, especially educational and encouraging. Never ceases to amaze me how industrious we can be when there is BIG BASS as the outcome!

Looking forward to hearing your review of the extra oomph provided by the TTLS, supplementing the TT.

Could you please do an A / B comparison, nothing technical, of your perceived output level between the two. Which one you feel is louder or any other pro's & cons between the two. You are a lucky man, being "allowed" not one but two TT's.

My sincerest condolences on you loss.

From the main page:

Measuring 15 inches high and 60 inches long, use the Long Style version if the WAF dictates a rectangular shape... It's the same TT sound, only the shape has changed.

Same response, folded differently.

Yeah Titanium Hand you noob...

[Titanium Hand]

Oooh, be nice fellas ha ha.

I understand what the plans say, I'm interested on what a fellow users ears say.

Reason behind this - as funny and brutally loud as my titans are stacked in my study 1.98m or 6 and a bit feet high, my missus actually commented on them looking good. All jokes aside, they are impractically loud for their temporary position!
A TTLS on the other hand, not quite as loud - but deep mmm, its got me thinking. I could set one up with a little plate amp & Boom! Could play movies through it and all. A few shelves off it even!

Hello there Titanium Hand! Glad you enjoyed my little journey so far.

I will try to A/B them a bit when I get the TTLS upstairs, but I do expect to hear some differences due to their location. My existing TT is almost perfectly loaded, shooting into a corner with the appropriate distance from the wall. The TTLS on the other hand will be shooting up against the angled ceiling wall, and may be a bit tight against the wall.

I don't know how much this will affect the sound, but we will find out.

Right now I'm designing a multiple amp box to put my two Dayton 240's into so they fit into my stereo cabinet. Once I get that built and everything upstairs, the experimenting will begin. I don't have any hardware to make objective comparisons, but I will certainly let you know what my old ears are hearing.....

Fantastic, Thanks NCDaveD. Its all about Subjective Listening to me. I thought a song I like had massive deep bass, turns out it was only 69Hz! Still huge all the same

[NCDaveD]

Finally got the amp box made out of scraps and took the first amp out of my original box and stuffed it in the new box. Nothing really much to look at, especially since it will be in the bottom of my equipment cabinet. But in case someone is curious as to what two SA240's look like.....here ya go!. The overall width of the ampbox is 19 5/8". I had to take the doors off to get it in.

Moving the TTLS in is next, then the experimentation begins

Honestly I'm a little bit scared even thinking about 2 TTs in a room. I hope you have a well built house.

Finally wrestled the TTLS upstairs w/help from SWMBO. Set it up in it's place and fired it up. In a word...disappointing. Muddy sounding, but louder. Thought about it a minute and realized that due to placement and running off a single LFE output channel, the two sub's soundwaves were hitting me at different times, which is probably what was causing the "muddiness". So I laid the TTLS down, aimed it at the corner the same way my TT is pointed and sure enough, the sound cleared up and became louder. It still is not quite as clear as the one TT by itself, but I've got a feeling the only way to clear it up is to split the LFE channel so that I can alter the phase of one sub to match the other at the listening position. I will admit that with the two TT's together, I had to turn down the LFE level a bit to get close to my original sound level. Unfortunately, I cannot leave the TTLS laying down.

Of course this means another piece of equipment and more $, so right now I think I'll just run my original TT and be happy.

So to summarize, I believe if you are going to try and even out your sub response in a room, you may as well plan on investing the $ and time to obtain equipment that will let you OBJECTIVELY determine what is going on with your system BEFORE you build another sub.

But what the heck, I had fun building the TTLS, and now I have something to add to my Birthday "wish list"......

Using two subs will help fix some room modes but the combined outputs also will create others. The next step is to use an appropriate EQ, like a BFD, to get the room response as flat as possible. Then you have two options, getting the best response at the listening position or averaging a few room locations. You have to accept the fact that perfection isn't possible, but you can get it pretty darn close.
