T39 size

[billgwaltney]

I purchased the plans for the DR200 and the T39s. The width of my trailer is 48 inches. My understanding is the DR200s are like 22" wide. If thats true this leaves me with about 25 or 26" of space for the T39s. So the question is, can I build the T39s 25" or 26" wide and if so how much do I give up in performance. I also need to know if I do build them in the 25" to 26" range can I run 2X12" drivers? This rig will be used for live band. Typically 5 string bass, miced drums, keyboards, guitar, and vocals.

Thanks
Bill

All of your questions are answered in the plans.

Lay them sideways and build them wide.

[LelandCrooks]

Wide as you can tote. More extension the wider you get. My personal opinion is 2x cabs are pretty much a waste, except for the t60. Instead of gaining 3db for a driver, why not gain 6db and build another cab.

Emm after doing some more reading I think I could build two tuba 60 slims and they would fit the layout of my trailer. From what I can see those will out perform the Triton with little problem.

Its your back... not mine. The T60 will go lower than the T39

The 20 inch wide T60 will have similar pack space to the 30 inch T39. It will be 21 inches longer though, which is enough space to fit another 30 inch wide T39.

First, know your extension needs, after that you can pick the cab. That's why there's different disigns, they have different advantages and compromises.

5 string bass goes down to 30hz... T39 has pretty *decent* output at 30 (crossover will pretty much eat that though). T48 has a lot better. As far as I can telly, you have little to no need for the t60... Unless you run a pipe organ in your band.

The T48 might be just right. Its 48x24x24 which would make stack nice in the trailer with the Dr200 and carries the lows. Course I have monitors, amp rack. Roll around rack that my onyx 16 makie, drive rack, EQs, maximizer, effects are all in. Plus mic stands, a 88 key korg and a 66 key motif keyboard stand bass guitar, err no wonder i dont have enough space

5 string bass goes down to 30hz... .

The fundamental is down there, but the fundamental output is miniscule below 45Hz. If it were not so the Ampeg fridge withe a 58Hz F3 wouldn't be able to handle the low B. Even the T39 is quite adequate for 5 stringers, as are the O15s, O12s and Jack 12s.
As for subs for live sound, for anything less than pro-touring I'd go T39. What the T48 delivers garage/bar bands don't really need. IMO even pro-touring doesn't actually need what T60 is capable of, we offer it because there's a demand, if not a need.

For live rock, even the jack has enough extension. Anything from bass guitar below 60hz and it pretty much sounds like mud, IMO. Before I go my SLA's and t18 for my 2.1 home system, I used to run the jack full range at home. I never missed the extra extension when listening to rock. However, you do want the most output at 65-80hz for the kick. This is where live PA shines.

And nah, try as hard as you might, I would never expect my t39's to ever hit 30hz. But still, it's not needed in the situation I described above.

I tried cutting 60 Hz and it makes things Blah imo. One man's mud is another man's bass. But yeah, 30Hz is not missed on 5 str.

That's because filter bandwidths are quite wide; cutting 60 Hz will affect everything from 30 to 120 Hz to some extent.

It all depends on your preference. One of our local bands has a bass player who plays a 5-string that he intentionally tunes a couple of notes low, and he reminds me every time I see him how much he enjoys playing on my system with the T36s. Most bands wouldn't notice the difference, but for the few that care, that extra low extension is all the difference in the world...

The t39 might not *hit* 30 hz... but then again, most bass cabs used by bassists wont really *hit* 30 hz again. I still think he would be a lot happier with the t39/top combo than with a dual 15 or other bass cab.
