| Overpowering Speakers Just a quick add on to make the point of sensitivity and power. All other aspects being equal, a 93db sensitivity speaker will play a volume of 111db using 64 watts. A speaker with 84 db sensitivity will play a volume of 111db on 256 watts.Your sp... | |
| Overpowering Speakers You have to double your power to get a 3db gain. It takes 3db to get a noticable difference in volume. If you are listening to a speaker of 90db @ 1 watt, 2 watts give you 93db, 4 watts give you 96db, 8 watts give you 99db, 16 watts give you 102db... | |
| Overpowering Speakers I don't know that I completely understand your question. If you like to play your tunes very loud, it is possible to blow them up with any amount of power. You are more likely to blow up speakers with a 20 watt receiver than a 300 watt amp. When y... | |

| Help power pair of Infinity Kappa 9's please Hi Jtiesel2, I ran SpeakerCraft/Marcof electronics, back in the early 80's. I had my own Stereo Store a few years in the late 80's,early 90's in St. Louis called Sounds Right. I've been a manufacter's rep for high end audio and 12v. I've built an... | |
| B&W Matrix 3 Series 2 - To mod or not to mod? Even if you sell, I would still replace at least 2. The bad one and the one in the same position on your other speaker. People will wonder what else might be wrong with the dust cap off.Bmanz420, I've been building speakers for 31 years. If your c... | |
| B&W Matrix 3 Series 2 - To mod or not to mod? Hi Bmanz420, Those dustcaps should be fine. The harder the cap the further out in the midrange the speaker is capable of playing (typically) As long as the weight is very similar to the old cap and the crossover point is below where the dustcap af... | |
| Help power pair of Infinity Kappa 9's please Jtiesel2,Do the surrounds actually have holes in them or are they just becoming weak? I've posted it on Audiogon before. If you have some old latex paint sitting around, open it being careful not to shake it at all. The latex and pigment will be s... | |
| Help power pair of Infinity Kappa 9's please http://www.stereophile.com/solidpoweramps/sumo_andromeda_power_amplifier/Stereophile review on the original Andromeda. Stereophile says to use a impedance compensation circuit on certain electrostatics, because they can show a dead short to the am... | |
| Help power pair of Infinity Kappa 9's please As far as the Andromeda comment vs the Aragon. The Andromeda II or III would not drive this either, only original Andromeda, if that is what they compared the Aragon with, I still understand it. The Aragon had better midrange than the Andromeda. T... | |
| Help power pair of Infinity Kappa 9's please I do not have them, but if anyone can get proper driver specs a impedance compensation circuit could be added. I worked at SpeakerCraft/Marcof Electronics in the early 80's we used this circuitry then, we had great computer programs, but it was st... | |
| Help power pair of Infinity Kappa 9's please The problem isn't power, its current capability. The Kappa 9's drob at one point down to .8 ohms. Most amplifiers will crap on themselves trying to drive a 1 ohm load. I have heard Kappa 9's sound decent on a 50 watt amp. Dave Cofin of the old Mar... | |
| Help power pair of Infinity Kappa 9's please Jtiesel2 One last thought. You might contact a few people known for mods. My thinking is that you take something like an Adcom 565, double its filter capacitance, double the voltage capacity of the bridge rectifiers, possibly have to change the tr... | |
| Help power pair of Infinity Kappa 9's please Thanks Driver, I appreciate it. I understand, I'm getting old, I have been in or around this business for 32 years. Sometimes I bite a bit too fast in my old age. As far as the Ampzilla above? As I stated in other area's, I used to sell Sumo. Jim ... | |
| Help power pair of Infinity Kappa 9's please I copied this from Audio Review. I hope this helps. He drives them with an Upper end Hafler. I am still using them in my living room, in a stereo system, fed with a Hafler XL-600 or (alternatively) a Hafler 9500 Series THX Power Amplifier and a Cl... |
