How well does the 45b's handle music?

For a time I used monitor 40's, the predecessor to the 45b, as computer speakers and listened to music frequently at the computer desk and enjoyed them very much. They don't go super low and can be a tad sloppy in the low end, but still sounded decent enough. If I were to give them a grade score they would be a solid B. Good for the money, but better options exist, generally at a higher price.

I held a surprise birthday for my wife over the weekend at her sisters house. They didnt have any speakers for music & I decided to take a pair of 45b's there and hook them up to their stereo system. Party was great the speakers were sounding nice and near the end of the night I took the speaker cover off & noticed the woofers blown. A few minutes after that I smelled something strange & then the tweeters blew. I showed my wife what happened and I said oh well I need new speakers now so she agreed to buy me floor standers for my birthday. That will be Black Friday so I will look for deals. Volume wasn't too high dont know how they perished so fast.

Yeah, the music volume seems to go lower with more alcohol. As the drinking progresses, the volume knob usually goes up. That's actually a cool way to get approval (WAF) for new speakers man. Nice move! tongue.gif

Was alcohol involved? It's my understanding that speakers lose 12 dB of dynamic range in the presence of good spirits.

Hey fellas,

I know I asked for advice on this already but ran into a issue so need further advice. I need to mount my surrounds. My ceiling is unfinished and I'll be mounting to the floor joist. I can't mount parallel to the main seating row because I have ducting in the way. So I can go 2ft in front or any distance behind. So what are the thots on this? As always thanks!biggrin.gif

Definitely behind the main seating are is better. Never in front.

Hell yeah. A9s will rock the house.

Keep this in mind though, without sufficient power (250 - 300W+) you can still blow the drivers if you crank it and clip your AVR or amp.

However, (pause for effect) with a good 300W or greater amp, you can easily go deaf way before you blow the drivers. Those bad boys are monsters and can deliver the goods. cool.gif

Ummm I wouldn't say never. If you already have rears, the side surrounds could go a tad bit in front, even a couple of feet but not more than a couple. Yes, behind would be better than in front IMO, but like I said, if you have rears, in front could be doable.

Very true Sir. I guess that would be especially true with dipole speakers. Thanks for keeping me on the straight and narrow. biggrin.gif

I don't mind going used, where is a good place to buy amps?

My home theater is my home theatre. I would have never thought about taking any speakers away from my setup only in this occasion for my wife. Otherwise noone touches it.

Craigslist, eBay, avs classifieds. Also consider new if you have the budget. Emotiva or outlaw audio both have great amps for even greater prices. You could also check out pro audio amps, crown has a few good models that are affordable, check out their xls series.

I agree with Crown. Just bought Crown XLS 1500 DriveCore Series Power Amplifier. It will power my two 15" subs. Bought from Parts Express. One down side is no remote and no 12v trigger. So it's either "always on" or you need to manually turn it on each time. Not a big deal but for someone like me where all components are behind a wall it's not handy. But great amp and great price. So I suppose I will walk the extra 10ft to turn it on. mad.gif

^^^if I didn't end up with my emo's I would have likely ended up with a crown. I actually demo'd a couple of crowns at guitar center. I like the look of more traditional ht gear better though, and when it was time to buy it just happened to be during Emotivas holiday sale....made it hard to pass up for the price. But those crowns xls amps are some very good amps and I would have no reservations, other then appearance, running them.

I agree. It sticks out like a sore thumb in my av rack. But my stuff is all behind the wall and ran with a Harmony 900 so no one will see it. But I know it's there.eek.gif

Look up the Adcom GFA 555 II on ebay.

Here is a review by Ken Rockwell.

The only problem I see driving subs with a crown xls is the 20hz hpf that is built in. Other than that its a solid amp for driving floor standers...I was going to pick one up.

I never even considered that. That would essentially negate any benefit of having 15" drivers over 12" ones. Wouldn't it?

Reading the discription I can't find that info. It does have an adjustable crossover.

I've re read the manual and don't see this anywhere. Also you can set each channel for low pass or high pass individually.

Yeah, I couldn't find it in the manual or the data sheets. The only low frequency reference I found was something about 50hz. Not sure though.

Yea I read about it in a few threads in the diy section...

http://www.hometheaterequipment.com/mono-stereo-amps-59/crown-audio-xls-drivecore-series-amplifier-official-thread-1319/index13.html

Look at the amp specs 20hz-20khz with a 12db per octave slope below 20hz.

12dB per octave below 20Hz... 102 times lower signal... Dang. That's a quick falloff. eek.gif Pretty much non-existent.
post #21927 of 35352
As far I know the only pro sound amps that offers FR below 20Hz are QSC amps and not in all models. I think only in DCA series (8Hz - 55KHZ and THX) and RMX series (5Hz - 50KHz) you will find an usable amp to drive a subwoofer, most if you want subsonic frequencies.

I've read many threads about using Crown amps to run subs. They all seem happy, even the ones referred to above. I think these amps are very well built and more than capable for the job. Especially for someone like me who likes bass but doesn't LIVE for it. smile.gif

Advice on Integrating Sherbourn Pre-1 into my HT:

I am a recent owner of an XPA-5 which I am enjoying quite a lot. During the recent Sherbourn fire-sale, I also picked up a Sherbourn PA 7-150 amp. and a Sherbourn Pre-1 pre-amp.. The XPA-5 is currently servicing an all Polk-audio LSIM based HT speaker system, with an Onkyo 818 already serving as a Pre-pro... My question is whether there is place in that configuration for the Sherbourn Pre-1 at all, or whether it would be superfluous. The Pre-1 is the first pre-amp that I have ever purchased, so please cut me some slack if I am sounding somewhat ignorant about basic functions of pre-amps.

I gathered from the little research I did before purchasing the Pre-1 that I could possibly integrate it into my Onkyo receiver + XPA-5 grid as the hub of an independent set-up dedicated to 2.1 channel music (the pre-1 does not have bass management, but that could be handled by sub attached to the Onkyo, at least in theory, but correct me if I am wrong)... This was all supposed to work quite well, because the PRE-1 has HT pass-through, and defeatable tone controls...

Now, my PRE-1 is here, and all of a sudden, I realize I have no idea how to implement my plan of incorporating it into my rig, or whether it is feasible at all, as everything I have outlined above was hastily conceived in theory, when I saw the price of the clearance sale pre-1.

In short, I need suggestions as to how best to set up this configuration. At best, the Pre-1 ought to find its place in the following set of components:

1. Onkyo 818 receiver
2. Emotiva XPA-5
3. Polk LSIM 703 Fronts, 704c center, 702 f/x surrounds, and 505 sub.
4. Miscellaneous music sources: CD player, Blu ray player, Playstation 3, HTPC, Apple TV. Roku 3 (maybe even a turntable)

I did mention purchasing the Sherbourn PA 7-150, but that is meant for another HT rig altogether, so it should not be factored into the above set up.

Any suggestions would be highly appreciated. If the Pre-1 does not fit well, I could just sell it, but I am sure you guys can help me come up with some role for the Pre-1 in the system to generate some kick-ass 2.1 channel music. Thanks again.

That would be redundant and a waste of a Sherbourn IMO. In a blind test you likely won't hear a difference. Of course your ears may be better than mine. That's my escape clause for the guys who have golden ears. Personally I would sell the Sherbourn or use it in a 2nd system where you don't need the receiver's bells and whistles.
