Driving 4 ohm speakers?

Hi guys, I was looking for some advice on driving a pair of 4 ohm speakers I picked up today at my favorite electronics wholesale chain. I've never heard of the brand before, but at $37 a pair I figured it wasn't a big deal if they were no good. The apparant construction quality won me over.

The speakers in question are MB Quart QLC104's, and according to the literature they are rated as follows:

Power Handling = 40-90 watts
Nominal Impedance = 4 ohms

I have a Sony STR-DE897 receiver, but it is rated for 100 watts at 8 ohms and I don't want to daisy-chain these speakers to create an 8 ohm load. So, what are my options for hooking these up? :confused:

More correctly, 4 ohm speakers are current hungry. You may be able to drive them, as Jayn said. Keep an eye (Ear?) on the volume. It really comes down to whether your amps are stable at 4 ohms, and whether the MB's are a constant 4 ohms, or do they dip down lower at some point. MB Quart for $37? Quite a deal.

I have a Sony STR series receiver (not the same model) and I can choose 4-ohm in the set-up menus. Does yours have that option? (I couldn't find it in a quick breeze through the 897 manual.) The audio section of yours specs-out very similar to mine however.

Over time I have had good (not perfect) luck with Sony Tech Support. Here's the link...

https://esupport.sony.com/US/perl/contact-email.pl?

Ask the question there. They usually answer within 24 hours.

I had MB Quart 2-way speakers installed in my truck some years back. Clear and "intense", could handle almost everything I gave them. I did add a sub, but for the higher ranges those pairs really rocked. Drove them with bridged amps providing 100 w RMS/ch if memory serves...!

jayn_j - I also reported a problem with a near-shorted speaker and that receiver. The unit would operate OK even with that short until I got to about -15dB or so of "reference", at which time the protection circuit would kick-in. You could fry an egg on the receiver at that point! I had even planned out a cooling system to help mitigate the problem. I musta damaged that speaker soon after I installed the system. What puzzles me immensely is how I didn't pick up on the problem sooner (d'uuhhh!) Once the driver was replaced everything returned to normal very quickly, no forced cooling needed, and I have never had a problem since. For most listening I can't get even close to "reference" without damaging the speakers and my ears. The receiver is at best only warm/warmer to the touch even after a forceful evening watching likes of Transformers and Ironman. Apparently it survived that short OK, but time will tell...

Well the Sony doesn't like the MB Quarts as rear surrounds at all. In 2 channel mode, it will drive them but not well. I need to turn the volume up quite a bit in order to get a comfortable listening volume out of them.

bhelms: My reciever does not have a 4-ohm option. Sony tech support has not answered me yet (I inquired prior to posting here).

In regards to going with a seperate amp, it seems the sony doesn't have any pre-amp outputs (other than the subwoofer) and according to the manual, the 2nd zone output only passes analog signals. Is this typical of 2nd and 3rd zone outputs?

I am looking at possibly upgrading my reciever and getting a stereo amp or two while I am at it. Reccomendations would be appreciated. As I said before, I have lots of speakers hanging around so I can put the Sony to use powering other rooms.

Finally, can you hook up some 4 ohm and some 8 ohm speakers as a surround sound sytem on a single reciever without powering some with seperate amps? If I bought a new reciever, would I be able to find one that can utilize the MB's as rear surrounds and my other 8 ohm speakers as mains, etc. or would I have to have an all 8 ohm or all 4 ohm setup?

Thanks for the advice! Gotta love all the friendly folks around here! :cool:

Comcast called fiber pricing "irrational" because the ROI is over three years. What is irrational to me is Comcast internet is based on lines they put in the ground decades ago at this point, for the most part. Is copper that much more expensive to maintain?

yes. even copper lines in a house degrade over 70 years, I doubt coax would last that long. Fiber Optic on the isp side will last over 70 years with very dedgration

The fiber coming in to the house looks like 300 ohm old TV wire I think that is the weak point.

Charter lost 77,000 TV subscribers, the bigger news, it lost 233,000 broadband subscribers.

You would believe both companies would of learned from what happened with their TV services, which was ignore that cord cutting was a thing, allowed competition ( streaming) to get a foothold in the industry.

Now, in today's world, there are more households in the United States without a paid live TV than those with.

Both companies charge too much, delayed upgrades, all because they believed no one would leave them, only game in town, competition started with the 5G services, Fiber soon after, enough said, Cord Cutting 2.0 is here.

Washington Post

SpaceX has held talks with Boost's parent company EchoStar in recent months about launching its own signature wireless service through a deal with the company, according to two people familiar with the negotiations.
Musk, the SpaceX CEO, has discussed the deal personally, meeting with EchoStar chairman Charlie Ergen last month, according to the people. The potential deal may result in SpaceX acquiring Boost Mobile or SpaceX gaining access to its network, which it leases from AT&T and T-Mobile US, the people said.
Access to those lease agreements would be a coup for SpaceX. The back door would allow Musk to make a play for a U.S. wireless market that equity research firm MoffettNathanson estimates is worth $235 billion. But the proposed service may need consent from those carriers for the service to actually launch, the people said.

Again, if so, why would he want Dish/Sling of all the providers?

He could deliver anything without actually owning, for example, watching the Lions game in my Tesla Y on it's screen via the YT app, while on the way to my future in-laws on Sunday.

Hate to say this no one is ordering Satellite TV. Both DISH and Direct no new customers.
After 25 years with centurylink DSL 80 speed i changed to Xfinity 300 speed for $50 wow lightning fast for streaming. Still have DISH 27 years with them. Americas 250 package for $103. What you think of superbox or vseebox for streaming is it legal?
Still dish is easy to operate and change channels. What will Charlie Ergen do with new super satellites with loosing customers with satellites and boost?

Song Name Game Part 3!

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....
