Matches that measured which should be around.

Then you should lower Qm of the driver so that the Qtc Simulate the effect of the enclosure filling so that the simulated Fc matches that measured You want to increase the enclosue volume to Your simulation does not sound quite right. But that's another story for another forum. I had great success with loose poly fill in my previous 3-way tri-amped 120 liter box, where I achieved -3dB at 30Hz with a 10" Scanspeak woofer. Ear check confirms the LF performance is still there. I used a much looser polyamide fill when I restuffed and tore the pieces up into small chunks. You've saved me many hours of impedance measurements.Īnd boy did they tightly stuff the box with fiberglas!!!. It should be fine for my experiment which was to fill in the low end of the Dynaco A-35s.Īgain, many thanks. But at least I now know what the LF performance should be. Of course, the project described in my previous post removes the tweeter and inductor. But this also depends on individual taste. With today's program material the tweeter should probably be in "Extended" position to move the tweeter xover up in freq in order to tame its output. So I'm finally understanding their design which was to boost the HF response for "older" program material ("Decrease" position). The large inductor on the LPF was there because of the high woofer impedance (23-50 ohms) at the 3-7KHz xover point (xover depends on where the switch is). WinISD shows small 1dB peaking between 50-100 Hz and a -3dB at 47 Hz. The large Vas makes for a Q=1 in the box. If you are not sure, Ask Before You Buy.Thanks so much. If you have an 11" mounting hole, these will not fit, if you do not have about 12 1/2" between the frames across the face of the cabinet, These will not fit. Measure your mounting hole to make sure these will fit before you buy. Advent had several different versions of the Large Advent, each varied from the other. You need to understand that before you buy.
#Large advent speaker series#
So we are Clear, this speaker only fits into the Large Advent Series Like the one pictured below. Note that you can also get this speaker in an 4 Ohm Impedance.for a 11 3/16" mounting hole, and a 5 3/8" mounting depth. A Practical Frequency Range from 30 Hz.Stiff Pressed Paper Cone with Rubber Surround.In about 5 minutes you're done, it could not be easier to bring those, Large Advents back to life. Just undo the screws, pop out the old woofer, disconnect the wires and do the reverse to complete the install. Remember, it is a simple process to replace any of the standard Advent 10"/12" Woofers. Rubber Surround and Heavy Magnet Structure High End Quality at a Mid Level Price. It has a Practical Frequency Range from 25 Hz to 5,250 Hz. The T元006Y-8, is rated to 250 Watts RMS with a Minimum SPL of 90 dB. You know as well as we do, once you are a Large Advent fan, you will always be a fan of this speaker. Over all still a very good sounding speaker, much like we remember, with a bit more low end puch. Proven and tested, it sounds just as good, if not better than the original Advent drivers. You remove the existing screws, unmounting the old speaker, unplug the old driver, plug in the new one, and secure the new speaker, using the same screw holes. it is a drop in replacement for the Large Advents. Mavin's Own 12" High Performance Driver will replace the Hybrid 10"/12" Advent woofer.
