Hartke Bass-stack vs. Table Tuba

[thijs666]

I bought this stack off of Ebay last week

It worked pretty well, although for 'my sound' I had to open the 30 and 40Hz slider all the way (+15dB) and close the 60HZ to about -10dB, 100HZ to -8 dB and so on...

...And then I connected my Table Tuba . MYGOD!!!! What a difference . I had to set the equaliser completely flat to not overtone the low E (Too bad I don't have a 5-stringer yet ). We're talking about a FULL STACK Hartke i.e. 1x15" + 4x10" vs. ONE ten-incher (the HL-10c) in the TT. Way , way, way more efficiency in the lows. I knew there would be a difference, but that is was this big . The Hartke is specd at 96db/W, 8Ohms, but I think that's at 1kHz or so

Now I want a TT to complement to my yet to finish DR250

But I'm guessing already even the TT doesn't keep up with the DR250, SPL/W's speaking...

So I will have to build a T39 or even a T48

Woohoo, my DR250 is finally done . It took some time to finish; more than I expected, but that's probably because I'm a rookie .

I tried it yesterday at rehearsal. I took my Hartke 1x15" and used the DR250 instead of the 4x10". Man, I'm spoiled . It performed almost the same as the 4x10" . Off course this was with only one 10" and way better highs, so I'm not at all dissapointed. Far from it . I still had to turn the 30&40 Hz sliders way up . But when I was standing in front of the DR, I felt quite some air coming out of the bass-reflex ports . I didn't hear any distortion whatsoever, but I wasn't sure:
1. you could hear distortion from the DR
2. I was overpowering the Deltalite II
3. the maximum excursion had been reached
4. it would keep this up the full rehearsal, because it started to smell like a new speaker being heavily abused, though I had been loosening it up with 50Hz/8V foor some 8 hours.

So I turned the 30Hz down to normal. Clearly I was asking to much of it in the lows, because the 60Hz slider had so much more effect when I moved it than the 30Hz one (just a little adjustment made a hell of a lot of difference ). Luckily I brought my 1x15" cab, so I ended up with a sound I could live with for that evening.

After rehearsal I tried some normal music with the DR. Man, is it ever gonna end . The loudness coming from only one 10" and a load of supercheap piezo's (I paid 1,70 euro's a piece, including shipping) is simply amazing. If you stay out of the sub-40Hz range, this cab just doesn't give up . And that's just one. I'm only beginning to comprehend the capabilities of a stack of these supercabs . And to think it only gets better due to coupling.

For most bassplayers I think the DR250 does a good job, but for me: 1 T48 coming up , ok, maybe two Or as a compromise, 2 T48's 14".

One question though, since the HL-10c is going out of production, is there a good replacement? Doesn't the 2510 have less Xmax, so heavily needed for the low-lows?

Don't run your DR250 with a lot of content below 50 Hz, you'll either toast or break the driver. Used alone I pull my 32 slider down, and never raise the 40 Hz above flat. It is just one ten, and the box is tuned to 50 Hz, so it does unload below that. For high LF output use it with a sub, and cross it over at 100 to 150 Hz.
