No, it's not bridgeable. If it was, however, the output at 8 ohms would be around 600 watts. I don't think that's quite right. I think you meant 300 watts? No, because when you bridge an amp it "see's" the load as half the impedance. So when you hook your bridged amp to an 8 ohm speaker it sees it as 4 ohms. Take my xls 1500's for example. They are rated 300x2 at 8ohm 525x2 at 4ohm and 775x2 at 2ohm. However, it's rated at 1050w bridged at 8ohms and 1550w bridged at 4ohms. Exactly double the 4ohm and 2ohm stereo rating. Notice there's no bridged at 2ohm rating? That's because it would present a 1ohm load to the amp. This is also why the xpa-2 was only rated to be bridged into 8ohms.

Can't run the A-300 as bridged but I got this response from Emotive customer care. "If you were to biamp a single speaker with the A-300, you would be essentially providing 300 watts to the speaker."

Part of the Biamp problem is that you DO NOT gain anything with the as-issued speaker crossover STILL IN PLACE. Each amp STILL produces the entire bandwidth and you don't get the BIG power boost you may expect. Gutting the speaker's crossover and inserting a LINE LEVEL crossover between the preamp and the power amp Will yield benefits. In my case, I have 2x200 per speaker. With the crossover about 600hz, I stand to gain nearly 3db and have the rough equal of 2x400 per speaker AFTER the install of a line-level crossover. Something like the MiniDSP would be neat. thespeakerguys.blogspot.com/2010/03/is-bi-amping-woth-it.htmlThis is the short form article, but if you are a real overachiever, go to Elliot Sound Products (ESP) and look up articles about biamping. The above is a good summary without much detail I've never heard a bridged amp sound as good as the 'prebridged' version of the same amp. Don't know why.

Are thereally any plans for a three channel variant of the basx?

I saw several YouTube videos from CES 2017 about Emotiva products and several new BasX offerings. It looks like a BasX cd player is on the way, and another multi-channel power amp (BasX 5125) with 5 channels at 8 Ohms/125 watts rms all channels driven. The new 75 watt BasX power amp is now up on the website, but not the CD player and the 5125 power amp. Pricing was given but not upcoming release dates. I saw some stuff that I'm interested in, but don't know when of if it will be released. It was not clear if the BasX line is above or below the Emersa line (or when or if the Emersa stuff will be released). The videos were interesting, informative, and frustrating.

Mark Actually I'm not sure if it's supposed to be above it. They said Emersa is their lifestyle line. I mean I guess it could be, above the basx line but I was under the impression it wasn't. More like a "different strokes" line.

Some of the Emersa amps do cost more, but they are apple to oranges comparisons to the BasX amps. The BasX has a 150 watt rms power amp, and, if memory serves me well, the Emersa was 300. Also, the amps are different designs, the BasX are class A/B amps. The Emersa two-channel pre-amp has several configurations and options, while the PT-100 does not. The Emersa line appears to offer more options, but I do not know if it sounds better or not than the BasX line in like products. I feel more comfortable with a traditional class A/B amp.

Dismissing Emotiva's BASX line as "lifestyle" (ala Bose) does the line a gross disservice. If you haven't HEARD the BASX components, then you're opining based on price and specs (both equally foolish). The BASX line is the best value in the entire Emotiva lineup. But let's throw out all considerations of value and compare the sound of the BASX components to Emotiva's best, regardless of price. One of the best systems I've heard is garbulky's Stealth DC-1 and Gen. 2 XPA-1s driving his Axiom M80s. Now that Gar's coated his entire room with acoustic foam (somewhat to the displeasure of Mrs. Gar), his system, despite the small room, images wonderfully, has bass, and sounds amazing. Now let's compare that system to my own - BASX preamp & power amp + Tekton Pendragons (no subs). I get much of the sound of Gar's system (say 90 to 95 percent) with the BASX components. Even more remarkable since my system has significantly less room treatment. In fact, we've thrown the BASX preamp into Gar's system before & it came amazingly close to his components. Gar needs the power that those XPA-1s provide - His speakers are 4-ohm and far less sensitive than mine. His DC-1 (in his system) is a synergistic match. But for my system, the Tekton speakers (8-ohm and high-sensitivity) allow me to get by with less. Now there's much that the BASX line lacks that Emotiva's more expensive gear provides: Bass management Balanced circuitry Selectable phono loading LOTS more power etc. But the point is, you either need those things or you don't. If you don't need the features or the power, what are you spending more for? I'm saying that my BASX components provide (to my ears) nearly ALL of the sound quality (and in the mythical double-blind test, I couldn't tell the difference - so toss out that "nearly") of Emotiva's best components. But (and this qualifier is the killer) your speakers must be "BASX compatible" to get that quality. Hook up my modest A-300 amp to Gar's speakers, and I (strongly) suspect that the performance would nosedive. I haven't tried, so this IS speculation on my part. But in my system, I like the A-300 every bit as well as the Gen. 2 XPA-1s I've previously owned. And in fact, I think I like the A-300 even better than the XPR-2 that I've previously owned AND better than the Gen. 1 & Gen. 2 XPA-1Ls that I've owned / lived-with. So is the A-300 "better" than those amps? It is not. Those amps will drive a far wider array of speakers than will my A-300. But with my Tektons, the A-300 can be "better" - and to me it is. So let's not dismiss the BASX line - it can hold its own with the big boys (IF you have the right speakers). Calling BASX a "lifestyle product" is a grievous mistake. Boomzilla

Boomzilla Boom, pardon my ignorance and knowing your fondness for the dragons, do less efficient speakers bring known benefits due to their configuration?

Hi foggy1956 - In fact, less-efficient do not bring known benefits. To the contrary, less efficient speakers require more amplifier power for the same volume. The extra power required generates more heat in the voice-coils. As the voice-coils heat, their resistance increases. As their resistance increases, their interactions with the crossover components change AND their power demands on the amplifier increase even more. In general, less-efficient speakers' cones also have to move further to generate the same volume. This increases transient intermodulation distortion. So in general, the more sensitive the speaker, the less distortion and the less demand on the amplifier.

I saw the CES2017 announcements for new BasX gear YouTube with Dan Laufman. But, so far, they are merely teasing me. Products announced at earlier CES events are still in la la land. Does Emotiva only announce new products and then not release them, and never admit they will not be released? Does anyone know about the upcoming soundbar? I was interested in the 125 watt per channel 5 channel BasX amp I saw on YouTube. But, so far that is merely a tease. Outlaw Audio has the same product with similar specs for $100 less than the "announced" price. I'm new to Emotiva and am still trying to figure out if they are trustworthy or not. Having the president announce and then nothing happens is not a confidence builder. If you change your mind after announcing, please do me and others the courtesy and have a press release where you state plainly the product is withdrawn and will not be released.

Boomzilla Thanks for this info about your observations. I have an Emotiva XSP-1 with KEF LS50 speakers. I'm making a decision on what amp to use. My natural inclination is to gravitate towards best price/performance ratio if I'm not taking a hit in sound quality. In the Emotiva line it looks to me this would be Basx A-300 rather than a new or used XPA amp. I'm planning to run 2.1 and the XSP-1 handles bass management, so I'm covered on that. All components will be within a few feet of each other so I'm not sure there will be a benefit for me to have an amp with balanced inputs. Is there any downside to Basx with my other components that you could anticipate? I'm auditioning the A-300 right now and the LS50s sound really good and three dimensional, but I haven't done very extensive testing.. What in your view makes speakers Basx compatible? When I asked Emotiva the rep that responded suggested the A-300 as it would provide ample power for the LS50s.

IMHO - A BASX compatible speaker has relatively high-efficiency and reasonably high impedance. Beyond that all speakers are BASX compatible.

The LS50 specs indicate: Amplifier requirements: 25–100W. Nominal impedance: 8 ohms. Minimum impedance: 3.2 ohms. So clearly the A-300 has enough power at 150W a channel. But I just wonder about how it will do with the impedance needs.
