    Default Tuba 30

    werthliving.com

    Hey all I am building a pro sub for my local church and just thought I would start a thread because I am feeling motivated at the moment. So for the driver I will be using a B&C tbx 100. For the amp we will use a qsc rmx 850. Funny the guy in charge of the sound booth used to be the regional sales manager for Bose and Danley sound labs, so I am seriously trying to make an impression on him. Who know's maybe this could be the ticket to getting into the sound industry for a living!!!! Also I want to send out a special thank you to ckone180 without him this would have been a much tougher road, and will add that if you are interested in any kind of DIY hit this guy up he is a great source of info and a nice fella to boot. Any way enough of that I actually got all of my panels cut today and assembled the first two parts of the interior horn design so I should make allot of progress tomorrow and have some pics for you guys to take a look at!!!

    I gotta tell you guys this thing is a ton of work, but I think it is coming together nicely, I should have the cab built tomorrow if I have time to go out and work on it.

    Dude that is some nice looking work! The first is always the most difficult and time consuming, but the sweat is worth the end product! Congratulation on the motivation. I can't wait to read your impressions once its done!

    Thanks ckone It i is allot more work than I thought, I really am shocked at the amount of work that is involved, but since it is a sub the pay off will be huge and allot of fun! Realistically I could bang one of these out in a day easy if my back wasn't jacked up, but if you don't do this kind of work for a living or haven't done much wood working at all you should plan on something like this taking you a good week or so. So far I have about 5 to 6hours into it. Hopefully it will be done tomorrow and I can move onto finishing it next week.

    I took me and two buddies 13 hours to cut and assemble the THT, then after the glue cured an additional few hours mounting the driver and wiring it up. It was difficult but fun as anything you can do with friends. Well worth the effort.

    Sorry no pics yet, but I am too excited to mess around with the final pics. I just got back from hooking up and calibrating this thing. I am speechless right now this thing is absolutely phenomenal!!!!!!!! WOW WOW WOW is all I can say. The thing is sooooooo musical and just tonally SUPERB The guy running the sound used to work at Danley sound labs as a regional salesman and he really doubted this sub big time. After hearing it he wants me to build more, he was beside him self and said this sub was every bit as good if not better than a Danley product and loved the craftsmanship of the build I did. Now to my knowledge Danley is one of the best pro sound subs you can buy. He says I can sell this sub for $2,200 easily!!! Man seriously guys this was one of the greatest days of my life to be complemented so much by a guy of his stature. I really feel this has opened up some opportunities for me. I will post pics soon.

    Ckone is the man for turning me on to this design BTW!!!!!

    So we had the first service today with the sub and again wow does this thing sound woderful, not only is there a ton of output, but it just flat out sounds amazing. Every note just comes through with accuracy and authority! Any way here are some finished pics. I and many other's are just floored by the sound of this sub, I must say I had my reservations about DIY before this, but damn this thing flat out over exceeded what I thought it would sound like by far!!!!!

    Oh I am, everyone else is singing my praises. This thing is so good it absolutely puts my HSU vtf3 mk 2 to shame!! It does not have the extension of my HSU but damn it has allot more output with much much less power and sounds way, way better!

    The more I look at this sub I wish they would have let me do a nicer finish on it. The box looks great but they wanted something that would not stand out at all and just wanted it painted white like the walls. I started another build it is a much smaller one and the finished product is going to be really cool looking, cause it is just for me so I can do what ever the hell I want this time. I will post some finished pics of it when it is done!

    What design type are you making for yourself?

    I'm very glad you like the Tuba! If you want extension and output, look at the THT or F20, or even Danley DTS 10. There is a guy from another forum that asked me what I'd recommend for a sub, and he went with the THT 24. He loves it and had it finished in a piano black lacquer that looks like a very high end mfg made it. He used a contractor from Chicago who put many finishing coats to get it that way. Looks spectacular. I can't wait to start my Seos build.

    You know ckone I think I am going to go with a line x type finish with flat black paint, since it will be for pro use. The lacquer black would be awesome for in home use, but for DJ use it would just get scratched to hell. However on the next t-30 with the line x and flat black paint I am also going to have a logo and some 28" long by 1.5" slats cut out on a cnc machine and painted a gun metal grey for some professional looking decorative pieces. I know a guy who has a cnc machine so cost will be very low on that.

    Right now I am doing this same design on the AT that I am in the process of building. I will take some pics and show you how it turns out.

    Man we had another service with this yesterday and HOLY S**T I just cannot believe the sound of this thing!! Me and the guy in charge of sound showed up early to have some fun with it, and the output is just tremendous. You know what is cool about this is that the output is flat out insane I mean the sound booth is in the back of a 100 x 50 x 10 room and all of the stuff on the counter by the sound board is walking off of the edge, papers are picked up and dropped with the push and pull of the sub, yet sound quality is the best I have heard. No wonder you thought REL was not impressive!!! BTW I won't look to danley so long as bills designs are around, the sound guy that worked for danley says this sub is every bit as good as any danley product he has heard!!

    ckone I hear guys are saying if you go with T30 to go with at least two, now this thing has 3 x the output we need so I don't get this rule. Now I can't help but wonder if the b&c driver has anything to do with my results?? What do you think?? I have asked bill and he says "no", but why do others feel the need for two of these bad boys.

    BTW do you know what danley uses for their drivers???

    The reason for 2 is for even FR in large rooms. Silly as it sounds, adding a second TH30 would only increase output by 3 dbs, but that is for any sub or speaker for that matter. As doubling the power is 3 dbs, adding a second with the same power as the first is just doubling the power. Thing is you're using this in a church, for services, this isn't needed unless you need to cancel nulls in the room. When you are filling a 250 person crowd with rock or some other music/PA gig, flattening that FR while still full pressure, you'd want at least 2.

    The finish you're talking about sounds great. I just mentioned the piano gloss as a reference for anyone who doesn't think DIY can look as nice as a high end mfg, as that THT looks the best of any large subwoofer horn I have ever seen.

    The Danley DTS-10 uses 2 modded Eminence Lab12s with 3" voice coils. The drivers in tapped horns usually don't make big differences in SPL or FR, they just need to be able to fit in the enclosure, handle the orientation,wattage and etc. The drivers are usually more affordable due to their lack of requirements, like great Xmax and wattage handling because its like an amplifier. It is actually like what Klipsch does with their tweeters, but for LF, so you don't feel its harsh due to unidirectional waves and such. Its really a fantastic design type, IMO.

    Well I knew adding another sub was only a 3db increase, I was just under the impression that many were saying that was needed, when in reality when you have roughly 200 bodies in a room no matter how you slice it a second sub would be a major advantage.

    I am going to try the AT out in my home and see how I like it. If I do I will likely part with my HSU and try out piano black finish. I also am very intrigued by the table tuba. I know the AT won't reach down deep like the HSU but these horns are so incredibly musical I think it would be worth the sacrifice. To think you really had to twist my arm to get me to try these babies out!!!
