impedance

I recently bought a pair of Beyerdynamic DT 770 pro 80 ohms. I mainly use them for listening to music from my vintage Sansui AU-317 II integrated amplifier connected to a turntable and CD player. My amp produces too much power so the lowest volume setting on the amp is already a little too...

Hello. I recently purchased an LG HT355SD for dirt cheap at a local fair to replace my failing LG LH-T6540. The new set uses (5 x 4Ω) speakers and (1 x 8Ω) Woofer. However, the speakers on the T6540 set sounded much better, so I was wondering if I can hook up the older speakers to the new set...

I have been trying to figure this out reading the different threads but haven't had much luck: I have an Onkyo TX-860 receiver which has a minimum 4 Ohm impedance. Now this amp allows for 2 sets of speakers to be connected to it and has a selector, Speakers A and Speakers B. The question is, if...

Hello, I recently purchased a Kenwood KR-1000. Which gets some flak in these threads over the design of the unit, but regardless of its looks, it has some serious power. I see this on the back of the unit, and begin asking myself..."does that mean I can run two 4ohm sets of speakers (B+C) and...

Hi All, One of my friend bought a 4900Z in a very bad condition. It was a long repair, including output transistor, preamp transistor, so called "protection circuit" (even the resistors were blown), some resistors and capacitors. Anyway, after All adjustments, I tested the system with 8 ohms...

Hi All I have a freshly restored and recapped (Shout out to Arnel Bautista for the amazing resto job) Sansui 5000X. I have a set of Sony ULM SS-7330 which are 6 ohm and a set of JBL LX44 which are 8 ohm. The 5000X manual says to use A+B both should be at least 8 ohm. Can I reliably run these...

Hello! Lately I've been struggling to wrap my mind around impedance and wattage. I have 4 ohm 90 watt rated speakers and amplifier rated at 8-16 ohms and 50 watts per channel. I have searched and searched for information but i can not make it sound logical. If amplifier wattage for 8 ohms is 50...

Optimus 4s have a woofer two identical tweeters, each of the tweeters are 16 ohm. None of the tweets were working so I disconnected the tweets from crossover and none had continuity. Didn't appear to be a simple fix on any of them (broke tinsel lead, etc), so I've ordered replacement 8ohm 2 in...

Hi All, I'm looking to put together my first HiFi setup and I'm keen to get a late 70s, early 80s receiver/integrated amplifier to pair with some entry level audiophile headphones. I'm struggling to understand matching headphone and receiver output impedance. With info like headphone output...

Hello all, I have a question about speaker impedance and the corresponding amplifier speaker terminals. I recently purchased a set of 8 ohm speakers to replace a set of 4 ohm speakers, and I neglected to swap the cables over to the 8 ohms speakers terminals. While I did notice a major difference...

My boss gifted these to me awhile back. I need to get an amp (as I just got into audio) I've seen other forum posts regarding these, but nowhere on any of them mentions impedance information. The speakers don't have it on them. Old brochures I've found also don't have the info. So now I'm...

Tube newbie here: So, depending on what I'm listening to, I use both 8 ohm Wharfedale W60s and 4 ohm Smaller Advents with a Magnavox 9303 modified (not by me) with Edcor transformers that have 4, 8 and 16 (I think) ohm taps. Currently the 8 ohm taps are attached to the binding posts, because I...

Hi, I've had a Yamaha RX-A770 for a few years with the Zone2 output sent to a pair of 6-ohm outdoor speakers. I wanted to add a second set of 6-ohm outdoor speakers in a different location, but be able to use either the first set of speakers, or the second set, or both. They would all be...

So I decided to do a recap for my Sansui SP-2000's. The story started here: https://audiokarma.org/forums/index.php?threads/need-opinions-sansui-sp-2000-replacement-woofer.899787/#post-13427340 I also have access to an impedance-frequency analyzer of sorts so I thought I would do some...

This is, I hope, a simple question. After reading lots of positive reviews, I've decided to go with a Hana moving coil cartridge. I still need to choose between the EH (high output) and EL (low output) models. My phono preamp is a Pro-ject Tube Box II, with these (fixed) specs for MC: Input...

I have the following components: Pioneer SX-3700 Continuous Power Output: 45 Watts per channel, min. Impedance: 8 Ohms What range of speaker specifications would I need to get some good sound flowing? I'm new to this speaker-to-amp match up. I just get more and more confused the more...

Hi all: I'm having trouble figuring the correct impedance matching for my setup: • A Pyramid/Sequerra 8w subwoofer (2 or 4 ohms, depending on strapping), Met 7 (4-8 ohms), and T-1 ribbon tweeter (12 ohms) for each channel • Each channel driven by a McIntosh MC2100 in mono/bridged mode (which...

I recently decided to experiment with my speaker configurations by hooking up my Paradigm Signature S8 in parallel with vintage Polk Audio RTA12's. I am unable to find the impedance of the Polks, but believe they are 6 ohm. The paradigms are 8 ohm and my Macintosh Amp has speaker taps rated at...

Hi Everyone, I have a receiver (vintage Sansui G-301) being shipped to me that is rated "8 ohm minimum" but the highest rated speakers I have are rated 6 ohm. I need to test the thing when it arrives and here is the question: will it be safe to hook up those speakers to the receiver, keeping...

I'm trying to ascertain the specification of the MC Impedance for the CA-2010. Service manual states 10ohm impedance, 50μV sensitivity. I'm considering a Audio Technica OC9-mlii and am not sure if I need a SUT. I spoke with Audio Technica and they seem baffled by the spec listed for the...

I got myself a pair of Sennheiser HD 424 some years ago. With aftermarket strange blue hard foams (see photo) which I replaced with NOS yellow ear pads. Lovely headphones to use while at work, etc. Fast forward to last week. Visited the local thrift store and found a pair of Sennheiser HD...

Hello Karmic Seekers, I'm hoping to make a list of all 4-ohm bookshelf speakers that the forum members have loved. Vintage and modern; economical and pricey.... (In my case, for a project in which I want to wire pairs of identical small speakers in series and have the final impedance come out...

Hey yall, So I have this kinda old Onkyo tx-904 av receiver. It has 2 sets of speakers it can output to: 2 main and 2 remote. On the back it says: "Main: 4 Ohm min/speaker" and "Remote: 8 Ohm min/speaker" I have 2 4 Ohm speakers and 2 8 Ohm speakers. However, for each speaker (both 4 and 8...

While chasing a problem with a receiver, I decided to check resistance of my speakers and speaker wires. What I got was this: Realistic T-120: a) 4.2 ohms b) 4.3 ohms Infinity SM120: a) 3.5 ohms b) 3.6 ohms These are all three way speakers rated at 8 ohms, and I just put the meter across...

What does anyone think? Safe to run 2 sets of speakers (8 ohm and 4-6 ohm) on a recapped 2270? Results in a 2.6 - 3.4 ohm load.... Would be only at very moderate volume for shortish periods... Safe or not?
