Tuba HT Low Profile (THTLP)


Beechnut

Recommended Posts

Looking at the plans, when you build the width (or height not length) can you go anywhere from 15" = 36"? Idea is to build 2 to flatten out the room response.

 

From what I've gathered, a 72" Long, 18" High, 36" wide should be apples to apples with a 36" x 36" x 36" Tuba HT. Many steer away from the 36" cube of the Tuba HT because they can't get it through the doors in their house...usually some of the interior doors.

 

I'm many years from a final home so the 72" x 18" x 36" THTLP seems good for me as I move around from place to place. Should be able to manage that in any home.

 

I'll be able to either stand them up behind my entertainment center towers, or lay them down, stacked on top of each other, behind it. Could also use them as risers it seems.

Those are space monsters for sure, but the low response must make the jaw drop!

 

I believe that alone (without room gain) they're good to 25Hz.  Not jaw dropping but very clean sounding.  With the room, it's lower.  Personally, If you need that "shape" I'd build F-20's.  3 Hz lower, the same efficiency, clean sound and the plans are free.  They're infinitely easier to build as well.

Yep. The F-20 is super easy to build, can be done in a day. My tuba table build (which is easier than the bigger THT) took a lot longer to put together and much more of a PITA both in number of cuts, angled cuts, and assembly. Both are good designs however.

The THT uses 1/2" plywood and the F-20 uses 3/4". The little money Bill charges for his plans will be made back with the less expensive plywood.

 

If your room is very large or open to other areas the full size THT is the way to go, frequency response is much flatter than the F-20 or the smaller THT designs.

If the room benefits from room gain you probably dont need a full size cabinet and can get away with a smaller version(s).

 

Build what suits your room or needs best and don't worry what is easier unless you're just lazy, once you are done you won't worry about the extra time you spent building what you really needed in the first place because you won't need to do it twice.

 

Follow the plans,read them over a few times before you start building and don't skip any steps, you will be done and listening to your new subs before you know it.

 

Just an option. You can mix width THT versions or use a Table Tuba in the same setup if the full size just dosent fit your space for any reason. Don't let the 8" or 10" driver scare you off as they still beat most mass produced models in volume + much lower distortion.

Yes you are correct in everything you said. You can see my two thtlp's facing into the corner in my profile pic. Both are 72" x 18" x 24. (the small one) I loooove my tht's and i highly recommend. They are also very helpful at the bill fitzmaurice forum. Hope i helped and pm with any questions. Yes they can be used as risers just male sure you bring out the tape measure and measure, these are some big suckers. You can also face them down....

Thanks for chiming in all.

 

Carl I hear you about the F-20. Honestly I'm still on the fence. Having the plans for the THT and THTLP certainly shows how much simpler the F-20 is to build than the THT versions.

 

More to follow on this. Time to stop being a dreamer and be a do'er. No better way to learn.

 

Regardless, I'll be adding some new tools to the ol' shop. Router being the main one on the list.

If money is an issue, you can use MDF on the F-20.  It's much cheaper but heavier as well.

I have a single THT and it fills my 4500 cuft basement with plenty of bass. Plan on building 2 more next spring. I'm good down to 15hz. So far I've pushed my THT pretty damn hard and I've never been able to push her into distortion. Watched MMFR today and had the sub trim at -1 through the receiver and volume at -14; sounded so good.

Good advice.

I hired a buddy of mine to build my THTLP.  Parts and wood were around $500 and I paid him $150 to make it from the plans.  I asked him to build it 18"x18" by 72".    I placed it against a side wall and stapled carpet to it, it lays down behind a couch but I sometimes use it as a seat when I have parties.
