Tannoy DC2000/3000

[bremen nacht]

I have a pair of DC2000s that I like a lot. I've just found out that the DC3000s use the same drivers in a bigger cabinet for extended bass response, so I'm thinking about copying the dimensions of the DC3000 and putting my drivers in.

Anyone know what thickness MDF the DC3000s are? or of any pitfalls? The DC2000s are very nicely braced internally, I'm guessing the 3000s use a similar design.

thanks

Thanks, Andropov - looks like a juicy site! I'm sure if the answer isn't there I can find someone to help.

hi,

i have a pair of DC1000, i wish to re-house them into some compact floorstanders, any ideas?

thanks

FWIW the DC2000s (same drivers as DC1000 plus an extra bass driver) are a closed box, unusually for tannoy. The bass is very controlled and un-boomy but not as 'effortless' as bigger reflex Tannoys.

You could try putting your DC1000 drivers into a similar sealed box and adding a subwoofer.

hi, thanks for that, if anyone needs any infomation about past Tannoy models, look at the Archive in Tannoy on-

is there anywhere that sells a crossover like the one in the DC2000, or can i adapt my DC1000 crossover for an extra bass driver?

thanks

I'd keep the existing crossover as is. Don't mess with the HF section, it includes a notch filter to get rid of a 3kHz (ish) resonance. I guess the LF section is no more than a 1.2mH inductor in series with the driver?

The DC2000 crossover for the LF units is simply an inductor in series with each driver, with a slightly larger value for the extra bass unit, so it's rolled off at a lower frequency than the DC. The value of the inductor you'd use depends on the driver. It's 2mH in the tannoy.

As the two LF drivers are effectively in parallel below a few hundred Hz, the DC2000 has a very low impedance at these frequencies and some amplifiers might struggle...just thought I ought to warn you! You might be better off using a separate amp to drive the new drivers.

good luck, let me know how it goes.
