The two 6.75 woofers in my B&W 803 D3 in my room did not produce enough bass to sound satisfying. Adding a pair of JL Audio powered subs took care of that, delivering clean, quick, natural-sounding lower octaves that blend seamlessly with the higher octaves. Careful integration with adjustments of X-over frequency, phase, polarity, and level yielded excellent results.

Submitted ’cuz the doors are left open around here, and yet another ’girth truth or dare’ expo... *L* pi x ( .5 + 2.5 ) x 7.25 = 68.33 ; it’s the way the cone gets excited that makes a Walsh work its’ magic with a 6.5 basket. The trick is to xover to a sub when the cone goes pistonic, bass requiring sheer air movement to create those lower and naturally omni frequencies in nature. Vertical alignment with a tweet based on the Infinity 'ice cream cone', a pair of which I used to own with the towers it lived atop. Had it's moments, but still sounded 'restrained' to my earlier ears... It does require a magnet structure matched to a really robust voice coil that can shrug off heat.... But they’re out there. 👍 Quixotic perhaps, but beats windmills. Reverb bathing.... 😏 Love it or leave it. ;) Appropo for tomorrow. Go hang with your neighbors and make some noise. |
"How many 6.5in driver equals one 8in driver" multi-diver (at one band, LF/MF/HF) speakers have a problem to sum different sound waves across frequencies without frequency, phase and linearity distortions. thus, it’s not possible to replace one good large driver with multiple drivers, and to have same SQ performance. |
I don't know what you are attempting to convince yourself of, but if you are looking for an equality of sound, then you cannot determine that by the size of the driver alone. There are far too many variables involved, including materials used, what type of driver (eg, long throw), and especially the cabinet size, dimensions, shape & ratios, ported or sealed cabinet, stand mount or floor mount and the position of the driver with respect to room surfaces. as an example, yesterday I heard a pair of Fyne F1-5 speakers with a 125cm driver (5") that went as solid in the bass region as a KEF R3 Meta with one 5" aluminum midrange driver and one 6-1/2" hybrid aluminum woofer. The Fyne was twice the price of the KEF but held it's own (and then some) with the larger drivers in the KEF. |
