1) ok guyz I’ve gotten email from alot of you wanting to know the skinny on this amp. I’ve spent several hours playing around with this amp so here you go. But anywayz if your new on Elite-this is a hobby of mine(test audio equipment and talking a little about it) My honest Arc Audio 4150-cxlr review http://www.arcaudio.com (pics and info.) When this amp arrived I was impressed right off with not just its size but how solid it really is. I’ve always thought the appearance was sweet on all the arc cxl amps-what can I say I love the color Royal Blue. The 4150-cxlr has what is called “set and forget” crossover settings that are located on the very bottom of the amp. I like this feauture because sometimes wondering hands of other people like to push every button they can find lol. I replaced 2 arc 2100-cxl’s(110×2) with this amp and didn’t notice any power loss whatsoever, in fact because the 4150 is microproccessor controlled it seems before audible distortion hits on the 4150 it is more powerful than my arc 2100 I had. If room is a concern the 4150 would be a great choice because it is smaller in length than my previous 2100’s. At this time this 4-channel amp’s purpose is to power my whole “sq” system. I said this because I know alot of you guys are interested in using the front channels of an 4-channel to power a component set and the rear bridged mono on a sub or so. Even better is this amp comes with a remote bass knob so you can adjust how much sub bass(voltage) you want at any given time from the driver’s seat. Since I didn’t have my subs right off I had plenty of time to run my amp using just the front channels(85×2) on my components. As I said before, the 2100 power is very close to the same as just 2 channels of the 4150 and as I said earlier I give the edge to the 4150 to do a little more clean power. I was pleased with the 2100 on my rainbow pro’s and couldn’t say a bad thing about it. What I noticed right off with the 4150 is that it has a warm sound to it(even at very loud levels) and it seems diffrent to my ears than any other amp I’ve had. Well, I got bored and decided to bridge my amp to my component set and was told it is at a Wooping 300×2! AHHH headroom lol! This amp keeped it’s cool even bridged and my speakers even sounded better. This is why they say to get all the power you can afford! Headroom is always a plus as long as you use your head using it. But anyways a long story short, This Amp Rocked my Rainbow pro’s hard at 75×2 and 300×2! Now, what you all have been waiting for-Sum Mono! Since I’m on the “SQ” Quest like alot of you I have been slowly upgrading as I can. I did my homework and Choose 3 Oz 250L Matrix 10’s(ported @33Hz NET internal volume of 3.9). I know your probably thinking that an amp just rated to do 320×1 will not do much to 3 10’s but this amp moves them very very well. I’m just like most of you so evenually I’ll give these subs more power. But I will say for the everyday driver NO WAY is it a need for more power-unless you get rich and are bored UPGRADE to more power! But otherwise this amp imo is great to run a whole system. The guyz at Arc told me they had this amp running a component set and 2 IDQ 15’s and it was very loud, judging by what this amp does to my 3 10’s I can imagine. But anywayz this amp gets an A+ for sub bass in my ride, it’s very clean and loud. I don’t use the sub bass gain control myself because I have an eq with fader, the amp is configured because I wanted 24db p/o crossover for my subs which is only available on the front channels wired at mono. Here is a side pic on what the settings I have done look like: http://albums.photopoint.com/j/AlbumIndex?u=1147375&a=11790015 I use the peq7 front and rear fade myself and am pleased with it very much so. This amp is more affordable imo than most highend 4 channels and cheaper than two 2 channel amps. I’m not the dude to email for pricing-it is Mic Wallace at: mic10is@rocketmail.com but drop me a line if you have a question you want to hear from me. Also, if you have any other questions you can call Arc Audio at: 1-866-258-0288 or you can post them and maybe Erik will answer them if he sees this thread. But anywayz guyz all I can say is this amp is a keeper and if you’d like one get YOUR own hehe. by the way the service Arc has is very good thus far. –Jason 02-28-01

2) I was also very curious about why this amp is expensive because if u think about it, u can get 2 2100 for a little less than the 4150…well after i hooked it up, it answered my question..a friend of mine has the 2100 so i asked him to hook that up to my utopia and did a side by side comparison with the 4150..we both agreed that the 4150 sounds warmer and more detail and makes his 2100 sounded like it’s dead..not to offend anyone with the 2100 because it’s a very very good amp, but compare to the 4150 it’s just isn’t in the same league..it’s the same company, i don’t know why such dramatic difference..jason aka jason sizemore also compare the 4150 to the 2100 and said the same thing..u can email his for more details..even though the 4150 is rated at 85×4, i swear it sounds like it’s 150×4..very powerful and very flexible crossover section..i also compared it to ADS PQ40 MCintosh mc431 and i found that the arc has a warm sound like ADS but more power..the mcintosh is a very nice sound amplifier with smooth response but not as much impact as the arc.-Troy 04-15-01

3) I have to agree with the perception the 4150 is a very powerful and clean amp. I have run a PPI 4100 and McIntosh MC440M on Dynaudio 340’s with dual MW160s in the doors, mid/tweets in the kicks. The 4150 has more headroom, is very natural and smooth sounding, like it is not there at all, which is exactly what a great amp is supposed to do, it will stand up to any amp I have ever heard, period. At two ohm stereo for the midbasses I had to set the gains to zero! How many systems have that problem, talk about fast/tight drum hits, whew! The mids/tweets were on the other half through custom passive crossovers, very crisp and clear. I recently installed a pair of Rainbow Refs and dual 6.5 Pros. Incredible is the only thing I can say! One 4150, three large midbasses, two tweeters, hugh passive crossovers and just flat out kick in the seat midbass, super tight and such real mids and tweets, never heard anything like it. I will be installing an Arc 2100 for the pros this week, another great amp, the Refs get the 4150 all to themselves. Would use another 4150 for the pros but just could not make it fit in the install. The 4150 is one very fine amp indeed. -Rick 05-15-01

4) Hey guys, I figured since I’ve had a good deal of listening time on Jason’s 4150, rainbows, and 250L’s i’d throw in a few words on the amp too. First off I’d have to say for sure that the amp puts out a fair amount more than 320 watts on the pair of bridged channels. The bridged channels really seem to drive the 3 10’s rather well. I’m 100% sure the 10’s could handle more power, but the amount they are getting from the amp is still rather stunning once you have a listen. Now on the components I honestly figured that they would lose some output when Jason went from the 2100 to the 4150 since the 2100 is rated with a bit more power, but once again it seemed like they gained a bit more output. They seem to stay controlled a bit better at really high levels. As a whole the amp does a great job of running the entire system. It’s definetly up there at the top of my “list of amps for next system”. I guess that’s about all I can really say about the amp since I’m no great audiophile or anything, but I figured nevertheless I’d try to be somewhat helpful. If you get the chance and the amp fits your needs go for it. I don’t see how anyone could be disappointed in it. -Shane 02-26-01

5) I got to listen to this amp for 4 days at CES. Demotrios was running a 4 inch prof. comp. set and 2 IDQ 8’s. Due to ambient noise, the amp had to be pushed fairly hard to compete witht the surroundings. This amp performed flawlessly over the four day period (basically 10 hours per/day straight). Not one problem. I did not get to compare the 4150 directly to the 2100, but I assure you it has all the power you need. If I did not have 2 2100’s already I would definately be using this amp to power my front end. Once I finish my home theater project I plan on switching out the 2100’s for the 4150. I need to make room for a 2050 to run my rears (I will be adding DVD with dolby digital/dts). -Rich 02-28-01
