| Break In Question? Only mechanical things need some run-in to reach optimal performance. Electronics - no. How simple minded. That is how a layman understand the universe. There is no such thing as "mechanical" or "electrical". It's just a way human beings cl... | |
| Help me clarify, is there a difference between 'forward' and 'bright'? The word "forward" and "bright" could mean a lot different to different listeners. Being forward can actually a good thing if implemented properly. If not it can sound too forward and hollow. Implemented correctly, it can have a soundstage slig... | |
| If It Ain't Broke, Don't Fix It The speakers are fairly priced at 1700.00USD. My take is the upgrade is quite expensive at 500.00USD or more. It's probably not worth it. He might have picked the wrong speakers to upgrade the xover. There might be case to upgrade if the origi... | |
| What Could Cause Center Image To Present Lower than Expected Ok, I fixed it. I'm in a 15 X 10 ft room. Speakers were along the short, 10' wall. Today, I moved them to the 15' wall, which means I'm sitting very close to them - but that fixed it. Soundstage went from on the floor, far away and teeny to com... | |
| What speaker is this? I didn't realize that the Ref 5 is quite a bit bigger and taller vs. the R11. | |
| Unable to hear back of the head sound effects The more coherent the speaker, the easier the effect is to hear. The information is mainly carried by the high frequency components of the signal, so clean high frequency response helps. As we age, we lose high frequency 'reception' so a combin... | |
| Unable to hear back of the head sound effects Please clarify...are you listening to multi-channel or to stereo (2 channels, speakers in front, maybe a sub)? It's on two channel stereo. It is most easily heard on a pair of headphones. It's not room reflection. | |
| How many 6.5in driver equals one 8in driver Here is an example of driving four 5in. driver. Basically it is two in series and then each two in parallel with the other. It is from Zaph, a very well regarded speaker designer. You can see below how the drivers are being driven. The speaker... | |
| How many 6.5in driver equals one 8in driver By faster I mean that a smaller woofer inherently must move further to move the equivalent amount of air that a larger one does so to keep up with the signal & remain tight & clean But if you have multiple smaller drivers that equal one... | |
| How many 6.5in driver equals one 8in driver The Math tells us 2.5 is the answer. I would up the ante to (4) 6.5 inch drivers equaling a single 8" driver. When designed and properly enclosed, an 8 inch driver/woofer can sound outstanding! Same goes for running (2) 8-inch driver/woofers in ... | |
| How many 6.5in driver equals one 8in driver Here is the impedance plot of SB Satori Textreme 5in. woofer. It stays pretty flat. | |
| How many 6.5in driver equals one 8in driver andy, how do you define driver impedance of 4 Ohms? It's the nominal impedance within the usage freq. range. For woofer, it is about up to 3KHz, after that the voice coil impedance kicks in to a gradual increase as freq. go up. The plot you h... | |
| How many 6.5in driver equals one 8in driver With my example above, if we consider the cones as "pistons" the increase in volume with double the distance traveled is 6 dB. If the combination of smaller drivers equals the surface area of a larger driver, then the cone excursion is the same... | |
| AXPONA Chicago April 10-12, 2026 - Who is going?? I am waiting for The Show in Newport beach from June 26 - 28, 2026. | |
| How many 6.5in driver equals one 8in driver in series drivers will modulate each other due to difference between all drivers involved in Z(f) impedance vs frequency behavior, thus is not common! If you drive four 6.5in. all in parallel, the total impedance will be each/4. If each 6.5in ... |
