Low-cost DIY practice/coffeehouse tweeterless 110 [long]

Edit: cheapo bathroom scale says 23.4 pounds. Take that with a grain of salt since this scale doesn't work very well at lower weights.

Weigh yourself holding it, the again not holding it. Subtract.

If you're reading this thread, you're interested in this little cab. If you build one you're entitled to membership in the TB110 Club! See here: http://www.talkbass.com/forum/f15/tb110-club-741202/

Good idea about spraying the bolt heads i'll think about doing it. One thing i noticed is that the box is actualy made from 5/8ths mdf but the front baffle seems to be 1/16 thicker than the rest.

tealrex: You're this close to TB110 Club Member #3! How much longer till you finish? By the way; I was wondering why my 3/4" screws were breaking thru the other side of my 3/4" MDF. Now I know.

 

[tealrex]

Haha. Man i'm so close. I'm still up in the air about contacting leland about the driver since mine is on bo till the end of the week at PE. Yeah the 5/8ths mdf threw me through a loop since i had bought a 100 3/4 black screws for the corners, handle, and jackplate. I ended up buying a bunch of stainless 1/2 inch ones from homedepot. Thats why i might leave the grill bolts stainless to match.

I didn't realize that - thanks!

Very creative build by the way, and nice job on the rat fur.

OK, got all my parts on Thursday night, put everything together on Saturday (I am a woodworker so the build part was straightforward for me); used 14 gauge lamp cord and soldered directly to the speaker lugs and 1/4" jack. fired it up for a test on Sunday and .....distorted sound! Speaker sounds like a fuzz bass, and at all levels and evenly. Checked my speaker cable to the head, bypassed the 1/4" jack, checked my solder connections, no difference. Pulled the speaker and direct-connected it to my stereo system out of the box, same problem.

Unless anyone has any suggestions, I'm going to contact PE and see what their policy is on bad speakers.

 

[mikeddd]

Hmm. That would be TWO bad S2010's from PE. Mine is not nearly as bad as yours, but same problem, more or less. I'm going to call their tech support and get an RMA# (you have to speak to tech support in order to identify "a broken/bad product") I don't feel so badly anymore. Thanks for cheering me up, bherman. In the meantime you can order another from Leland at Speakerhardware.com; PE is out of stock on these until 18 Feb, I believe.

Wow, major bummer!

I called my contact at Parts Express and he looked at his resources and said there were no notes about problems with this particular run of S2010s, so I think it's just a bad roll of the dice. He said they had a shipment coming in this coming Friday (the 18th).

I just got off the phone with a tech rep, they are a great company to work with. Sending me a free shipping label to return it, they'll check the replacement speaker out before they ship it.

I'm just bummed that I have to wait another week to fire it up. Thanks again Duke for a great gift to us TB members.

 

[tealrex]

Thanks Duke for the kind words and the idea for the build. Once i get the driver and the port tuning situated I'll be all set. I emailed Leland at speakerhardware he's all out of s1020's as of this morning.

 

[mikeddd]

@tealrex: PE told Duke they have more S2010's coming in this Friday. I do believe I got Leland's last one: I reallllllly hope it's not out of the same batch as the one I'm sending back to PE. *fingers crossed* BTW: I got my RMA# from PE; shipping it back tomorrow.

 

[tealrex]

Good lookin out Mike I'm on the PE bo list already so hopefully their projected due date is accurate. I get antsy when i don't have any new toys to play with. Haha

 

[tombowlus]

Oh yes!

And I suspect somewhere down the road we come across the reason teenagers have skinny arms, which is so they can reach that spinning T-nut on the far side of the woofer with those needle-nose vice grips, while dad tries not to cuss too much in front of them...

LOL! Man, you guys are great! This looks like a really fun thread. I may have to try and build me one of these cabs (not that I need another cab... ). It just looks like a fun project! Thanks so much for sharing Duke (and greenboy)!

By the way, you can lift this cab with just your pinkie.

Nice enhancements - looks good.

Duke i do have a question for you. I added 1 1/2 inches to the length of the port. Any idea how much of the port will need to be blocked now that it is a little longer? i play a fiver so i'd like to get that lower tunning you where talking about.
thanks

Sorry, I'm not Duke, but I'll comment. As I think you know, you've lowered the tuning by lengthening the port. Rough guess - maybe 4hz? Reducing the port width will further lower the tuning, maybe by a little more than the 1hz per 1/2" Duke quoted for the stock port. Duke would have better estimates, but you might have to experiment, since these narrow shelf ports act longer than they are.

 

[mikeddd]

So yeah...you know when you just finish a project and you're on that "building something" kick? Finished my TB110 only to discover that the woofer was bad; it's on it's way back to PE and hopefully a good one on it's way to me. So I'm thinking "What else can I do to this thing while I'm waiting?" Ah yes! SILICONE! Never too much silicone! Even though I couldn't detect any leakage, I did cut the terminal cup opening a bit too big. And, so I rationalize my itchy-fingered tinkering. I guarantee there won't be any air leakage now. Even gooped-over the unused 2+,2- terminals on the Speakon. All hail Ye Olde Excess of Goop! (Yes; I used too much. That would be "just enough") The silicone I"m using comes in the big tube you have to load into the squeeze gun thing. I pre-pumped the thing too much. When I pulled the cap off it just oozed all over. So instead of wiping and throwing it away, it got smooshed all over. Never too much silicone!

 

[Triad]

Now the cab weighs like a 4x10"

 

[mikeddd]

LOL! Darn near it. I had already cut the tube open the other night when I built it, intending on doing this very thing. But there were no air leaks, then I got distracted by playing this awesome-sounding little beast, then I got really distracted by the defective woofer...and I still had the tube. Being that the cab is open for at least a week...well, you know. SILICoNE!!!!!!!
