To get the best sound quality out of … To contact the forum owner hit the Contact Us link. The amplifier can only operate correctly if the amp is wired to the speaker the right way. View cart for details. My research, thanks to an older Sound and Vision article listed the specs of the speakers as being a 3-way port-reflex designed speaker at 88dB sensitivity at 4Ohms with a frequency response of 27Hz-20kHz and featuring a 1″ silk dome tweeter, two 6 1/2″ aluminum cone mid woofers and a 12″ aluminum-cone woofer. What About Sensitivity? Chad didn’t specifically mention it in his e-mail, but I assume this will be a two-channel music setup and not a home theater, multichannel surround setup. I wasn’t able to confirm the exact spec’s Chad sent. I’ve followed Michael Fremmer’s in Sound and Vision and Stereophile and now Analog Planet for many years and he’s always been one of my favorite audio reviewers. This is why you never play a tube amp without a speaker connected. There seems to be a problem serving the request at this time, {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}. For instance, a 4-ohm amplifier can run any total load of 4 ohms or above, including 16-ohm cabinets and speakers. Never halve it. For a tube amp doubling or halving impedance shouldn't be a problem. 14 product ratings - Stetsom Hl 2000.4 2000w 4 Channels 2 Ohm Car Audio Amplifier 3 Day Delivery, 6 product ratings - Power Acoustik 5000 Watts 4 Ohm Class D Monoblock Amplifier with Bass Remote, 73 product ratings - Taramps TS400X4 Full Range 2 Ohm 4 Channel 400W Class D Car Audio Amplifier, 3 product ratings - Used JBL CLUB 704 4 Channel Class D Amplifier 100 Watt RMS x 4 @ 2 Ohm 1000 Max, 7 product ratings - Stetsom IR 400.4 2 Ohms 4 Channel Amplifier EQ 400 Watts Car Amp 3-Day Delivery, 50 product ratings - Alpine BBX-F1200 600 Watt 4/3/2 Channel Amplifier Car Stereo Amp Class-A/B 2-ohm, 2 product ratings - Soundigital 800.4d EVO Series 800w 4-channel Car Audio Compact Amplifier 2 OHM, 1 product ratings - NEW JBL Stadium 1000 4-Ohm Stable Monoblock Class-D Car Amplifier w/ Bass Knob, 5 product ratings - Alpine S-A32F S-Series 80x4 Watts RMS @ 2-ohms 4-Channel Class D Power Amplifier, 14 product ratings - BOSS Audio Systems R1100M Monoblock Car Amplifier 1100W 2/4 Ohm Stable Class A/B, 6 product ratings - MASSIVE AUDIO E4 4000W MAX 1 OHM STABLE MONOBLOCK EDGE SERIES AMPLIFIER CAR AMP, 4ohm Amplifier Indiana Home Audio Amplifiers & Preamps.

Otherwise, you can’t go wrong with either the Emotiva/NuForce separates or NAD integrated. What’s the Difference Between FLAC vs ALAC Lossless for audiophile recordings? There isn’t much else that I’d confidently recommend that you consider given your email, your requirements, and what I know good clean power can do to help the overall presentation and clarity of a good set of reference speakers. Wiring a 4 ohm amp to a 2 ohm speaker is done often by car stereo enthusiasts. To see the prizes and rules: no, it won't damage your amp,just make it quieter. The transformer stores energy as a magnetic field as that field changes it induces a voltage potential in the windings, this is voltage on top of the B+ voltage from the power suply. These speakers retail for $2,899/pair and Chad got a steal of a deal on a pair through an auction—Congratulations Chad on your new purchase! More importantly, an integrated amplifier typically has superior amplification vs. a receiver. I received an email from one of one of our readers, Chad, who got an incredible deal on a pair of RBH Sound1266-SE speakers. eg an 8 ohm cab is fine with a 4 ohm speaker out. © Copyright 2016 - The Poor Audiophile - Site Designed by, NuForce MCP-18 preamp (on sale now from $995 to $599). The higher the sensitivity of a speaker, the louder it will play at a given power level than a less efficient design. Cambridge Audio Yoyo (L) review: The perfect audiophile streaming speaker. An integrated amplifier is another name for a two-channel receiver. I’d pair up the Emotiva with either the NuForce MCP-18 preamp (on sale now from $995 to $599) or the Parasound Classic 2100 Stereo Preamp ($695 retail).

MartinLogan Dynamo 1100X Subwoofer: High tech and earth-shattering bass. Enter to Win one of two Strats we are giving away! NEW JBL CLUB 704 4 Channel Class D Amplifier 100 Watt RMS x 4 @ 2 Ohm 1000 Max There is a pretty big safety margin built into the transformers, but at some point the voltage cam rise to an unsafe level and arc from one one winding to the next, shorting out that winding and basicly killing the OT.

One caveat I want to mention: at your target price point of $1,000 you aren’t going to find many options giving you lots and lots of power. If there is no path for that voltage potential to cause a current flow, the voltage can get very high, like several thousand volts. Determine the load the amp wants to see and match it or double it. Assuming such a two-channel setup, I’d recommend an integrated amplifier over a multichannel receiver. An American Pro II Strat HSS and a Squier Classic Vibe Strat. You can operate 4-ohm speakers with an 8-ohm amplifier if you use caution and understand how impedance works. Let me know how your search goes Chad and I hope you find a great deal to go with your new RBH-1266 SE speakers! 1 - I was told by a tech to follow 1 simple rule. The Sound and Vision review was done by Michael Fremmer. eval(ez_write_tag([[580,400],'pooraudiophile_com-medrectangle-3','ezslot_2',187,'0','0']));I’m not intimately familiar with the speakers so I did a bit of research on their specs. https://www.strat-talk.com/pages/2020_Fundraiser_giveaway/, https://www.strat-talk.com/account/upgrades, (You must log in or sign up to reply here. Copyright © 1995-2020 eBay Inc. All Rights Reserved. Improper wiring can cause malfunction of the amp and speaker. Deal of the day for today only. Something went wrong. By “superior amplification” I mean in both watts per channel or power and the ability to handle lower impedance speaker loads.

If you can stretch your budget, I think you will be ecstatic with the Krell. Where that point is not predictable, as a rule of thumb, you can go one step up, often you can go two steps up, but no one is going to tell you 2 steps up is safe. Eight-ohm speakers can be run with a 4-ohm amp. ). How to play high-resolution audio with Apple iTunes. Power handling is listed as being between 20-250w. An integrated amplifier (typically) assumes analog or digital (non-HDMI) sources. Now less extreme then an infinite load would be a speaker of higher then rated impedance, There is some current flow drain off the energy, but it is not happening as fast as it would with a lower impedance, so the voltage will rise higher with the higher impedance then it would with a lower impedance. I’ll give you some options I’d consider given what you mentioned in your email. But it is 2 steps in the wrong direction for a tube amp, so the chance of damage does exist. Discussion in 'Amp Input - Normal or Bright' started by BluesRock41, Apr 22, 2012. Pioneer receiver $199 from $499 on sale. One 8-ohm speaker plays loudly with only half the current from the amp, but if two 8-ohm speakers are connected in parallel, the resistance in each speaker falls to 4 ohms to match the amp. It probably will not damage anything. A well designed 4 ohm speaker system will usually present a more ideal load to an amp than a poorly designed 8 ohm speaker. Most modern amps can be used with speakers that have a total load at or above the minimum impedance rating.

what will damage an amp is using a 4 ohm load on an 8 or 16 ohm amp. Chad wrote in that they are 4ohm speakers and take a max of 300w for amp power. Michael gives the RBH speakers a glowing review. A 2 ohm cab will tax the output tranny so don't do it 2 - I was told by another tech you can go up or down one. eval(ez_write_tag([[580,400],'pooraudiophile_com-box-3','ezslot_1',138,'0','0']));Chad’s specific question was, now that he has the RBH Sound 1266-SE speakers, he feels as though he has nothing strong enough to power them and is asking for guidance on a good receiver under $1,000 that would be a good fit for the speakers. On sale now for $314, this 125wpc into 8 ohms and 200wpc into 4 ohms amp will give you plenty of power for the RBH 1266-SE speakers.

With tube amps (transformer coupled amps really, there are transformer coupled transistor amps and there are output transformerless (OTL)tubes, but they are rare so I will ignore them for now), the killer is "flyback' voltage.
