Hi and thanks a lot.
I like them even if a side woofer is not my best choice.
i usually listen a speaker from the front.
For the price no doubt.
kind regards.

Side firing woofers can be addictive if set up properly, but you'll need a larger room to keep them away from side walls. My friend has a smaller room and is already complaining.

Hi again !
In my ideal listening room wall reflections are suppressed, like a semi-anechoic listening room.
I do not like at all "live" rooms, very reflecting.
Moreover only frontal emission and quite narrow sweet spot.
I do not like bipolar speakers.
Just to give and idea i like the Tannoy Dual Concentric concept immensely.
Actually i do not understand why it is not more popular.
Very very fascinating concept.
Kind regards,

I have Tannoy dual concentric speakers in my BR system. I bought them new in '76, cost about the same as one year's university tuition, my parents freaked. My money, and I know what's important. :)
Hi !
so i am not alone. However i listened to some Tannoy DC with plastic cones the DMT or DTM series and remained puzzled.
I like paper cones versions better.
For instance i would like to listen the Eaton drivers in decent cabinets.
I am sure the effect would be even better than what i heard.
Kind regards,

Wouldn't you just swap the speakers and have the woofers firing inwards if they have to be near a wall? If them firing at a close wall is a problem that is. Have to admit I've never seen, never mind heard, speakers like that before. I'm sure I could find a good use for them regardless at the price paid...
Remember that low frequencies are very long wavelengths, and much larger than the size of the driver. This makes them essentially omni-directional below about 150 Hz for 12" or 15" woofers. So, it really doesn't matter if the woofer is oriented to the side, the front, the bottom or the back, except for the upper frequencies involved in the roll-off. If a woofer is crossed at, say, 100 Hz at 12 dB/octave, 200 Hz is down 15 dB, which has a wavelength of approx 5.6 ft. Depending on the room surfaces, this may or may not matter. If the woofer is crossed at 75 Hz at 12 dB/octave, it's not likely to matter what orientation the woofer has, since 150 Hz will be down 15 dB with a wavelength of about 7.5 ft, and that frequency is still essentially omni-directional when produced by a 12" or 15" driver.The question becomes: What is the significance of a second or third harmonic which is 15 dB down in the low/low-mid frequency range?
So, the crossover point and slope are important variables in woofer orientation.

I have a pair of Coincident speakers with side firing woofers. Turning them inwards results in one note bass, which gets pretty annoying pretty fast. Luckily, I'm blessed with a decent sized listening room.

Ah, OK, figured there must be a good reason. But that can happen with subs too if not well-designed/integrated/positioned.
For Inmate51: yes, I know about that, for subs at least. Down-firing, side-firing, forward-firing, I've tried 'em all. Didn't realize these woofers might actually be (quasi-?) subs, but I did catch they had their own built-in amps for the woofs. So if they are quasi-subs, close to walls would definitely be "bad" IME, one-note and potentially boomy etc.
