![]() If you aren't positive that your amplifier can handle four-ohm speakers, make sure you stick with a matching impedance, which is often listed on the back of the receiver. Higher-end A/V receivers may support four-ohm speakers, but this isn't something you'll see in lower-end models. When youre looking at loudspeakers across the board in the market, almost all modern models are using 4 ohms, because thats the way you get the best use out. That said, as A/V receivers continue to increase channel counts for home theater systems, we're seeing fewer and fewer with this setting. Other amplifiers have a switch built-in, usually on the back, that enables you to choose various impedance settings. You'll encounter some receivers, especially more expensive models, that are fixed but can handle 100 watts at eight ohms or, for example, 200 watts at four ohms.

Many stereos and A/V receivers are fixed and are only meant to be used with speakers of the same impedance. SV212 Studio Vintage 140-watt 2x12' Vertical Extension Cabinet.

The vast majority of amplifiers and speakers you see for consumer use like home stereos or home theater systems come in four, six, or eight ohms. In others, the amplifier will attempt to pump out enough current to match the resistance of the speaker, which is lower than its own, and damage itself in the process. 15' Replacement PA Speaker, 600W at 8 Ohms, 35Hz-3kHz Frequency Response, with Cast Aluminum Chassis and Glass-loaded Paper Cone. This is like pouring a one-liter bottle of water into a pipe capable of handling far more at a given time. Celestion FTR15-4080F 15-inch 600-watt Cast Chassis Replacement Speaker. In this case, the amplifier can't provide enough current because the resistance is lower than its own. The amplifier isn't going to attempt to pump out more than the speaker can handle.īut what happens when you have a mismatch? Say you've got an eight-ohm amplifier but a four-ohm speaker. Related: Audio Channels: How Many Do You Need for a Home Theater?Īssuming that the amplifier and speaker are rated at the same resistance of eight ohms, everything works as it should. You can pump all the water you want into that pipe, but at a certain point, no more water can flow through that pipe. One thing's for sure, I'm learning a lot here.Again, if you think of an audio signal coming from an amplifier like water pouring out of a spout, you can think of a speaker as a pipe. Am I getting more or less wattage, etc.? Is the amp working harder or less? Why have I always heard it was wrong to do this and why the warning? Publisher: Home & Studio Recording - Music Maker Publications (UK), Future Publishing. Now my question is why? Why is the 8 ohm tap providing better results for a speaker that is 4 ohm? Also, what is technically happening to the amp (my Dynaco ST-70) by using the 4 ohm or the 8 ohm. Bi-Amp Stereo Graphic Equaliser Quad 303 Monitor Amp Solavox TK60. Thank you very much for this tip and also a good demo piece to "hear" for myself. 5 Core Speaker 15 Inch Bookshelf Studio Speakers 200W RMS 8 Ohm Durable Speaker Cabinet W 3' Voice Coil Premium Passive Loudspeaker 15x1 200DX. I'm leaving the speakers feed from the 8 ohm tap (gee). I also listened to some other sources with both channels during the evaluation. Hi I bought a Marshall MX212A cabinet which comes with 2x Celestion Seventy Eighty speakers, 16 ohm each speaker, with parallel wiring (2x 16ohm speakers 8ohm load). The 4 Ohm tap use seemed a bit bland in comparason (kind of squeezed and not going anywhere/dificult to explain). Each bass note had a nice roundedness to it compared to the 4 ohm tap which lacked the same kind of "life"/lack of dynamics (especially when the drum bit comes after the instrumental). Kali Audios Lone Pine Series studio monitors are designed to allow you to hear every detail thats happening in your mix. ![]() The bass & drums were a lot tighter/more defined and it had more punch. For example, matching 4 ohms with 16 ohms sounds unrealistic and would result in an overheated amp if it’s not designed to handle big loads. The problem comes in when trying to match speakers with a huge difference. Okay, I spent two hours listening to 'I Feel Fine' (drums/bass side) and it does sound better on the 8 ohm tap. Intermixing 6-ohm and 8-ohm speakers shouldn’t be a problem because the range isn’t too much.
