2 x 210s: Vertical or horizontal stacking?

I once did some experimentation with the effect of a slot alone, as opposed to a full horn. A slot lowered the effective Fs of the driver by as much as 25%, which is a plus as far as the low end is concerned. But it also lowered the upper corner frequency by the same amount.

I wondered if these would get a mention. Bit of an oddity in the bass guitar world, and I recall them polarising opinion a fair bit too! Neat idea though, 4th order bandpass but a port that radiates directly and modifies directivity at the same time. Scoop city when you fired them up, it wasn't very hifi!
The contribution of chamber resonance to the output of a foam blocked cab is by comparison going to be negligible by guitar/bass cab standards though...

These little things sound stunning with a Precision through them. Not so good with a Jazz. But then I guess you'd probably worked that one out...

Is that a big problem if you also have a tweeter, as in the picture?

It is if you like mids in your sound.
Instant smiley face graphic for those who like that though.

Even best case there's an octave wide hole between where the useful high frequency response of a woofer stops and the average tweeter begins. This cab is a long way from best case.

Ok, I see what you're saying. Thanks Bill!

Ahh, but what if you set the EQ to a sad face?



Would you get the mids back or would you just have a sad face???

I hope it looked a bit better than that when it was new.

I was tempted to buy one of these about 10 or so years ago, it was one of the few small combos that the local "music" shop had.
I decided not to though.
