What is best center speaker?


I have an HT set up with bryston 4b amps (4 ) an AV 9000 marantz a 65in HDTV and Piega P10 as fronts Piega P5 as back and the Piega Center. I have now blown the center twice and am tired of sending it back east to be fixed. I need a center that will fit in with the Piega and will take 200 to 400 watts and sound outstanding. Does a center like this exist? (The Piega center is a wimp)Thanks for your input.

Nick: You can't expect a relatively low efficiency speaker using two small drivers to do low bass and play loudly and do it cleanly. As such, you have to accept that there will be trade-offs with such a design and either limit the volume and / or the amount of low frequency information that you are going to send to the speaker. As such, the suggestion from Foreverhifi to run the speaker on the "small" setting may help, but i don't know if it will get you all the way there.

By the way, what are you "blowing up" on this speaker ? Are you killing the tweeter, one or both of the mid-woofers, part of the crossover network, etc ??? If you are taking out specific parts, such as the tweeter, ask Piega to change the slope and hinge frequency of the crossover to something a little more conservative. If it is the mid-woofers, tell them that you want a custom model with four mid-woofers rather than just two. They can series-parallel the drivers. While this will will raise the impedance, it also increase power handling / maximum SPL capacity. You've obviously got plenty of power since you are smoking the speaker, so the change to a higher impedance probably wouldn't hurt you any.

If you want to avoid all of this, switch over to running another P10 for your center channel. That is, if it is possible. I agree with Sugar that running identical or a near identical center speaker to what you are running for the mains seems to work best. Piega may cut you a deal on a single P10 since you've already had problems and it may be cheaper for them to help you out than to have to repair the speaker under warranty. That is, if they are covering the repairs under warranty. Sean

PS.. Forever: You might be surprised how well my low efficiency, low impedance "audiophile type" center channel speaker does in terms of bass extension and high spl's while retaining good clarity. Then again, with 800 watts driving two 8's, a dome mid and dome tweeter in a 4+ cu ft cabinet, it's not exactly "under-powered" or "little" : )
Ksales: I agree that this "shouldn't" be happening, but we don't know all of the variables involved. The system could be severely out of calibration with the center being relied upon to provide the majority of information, the room may be VERY large, so more power is required to achieve the required spl's, etc...

Having said that, i have a hard time figuring out how people "blow" speakers, especially woofers. I have POUNDED very generic drivers with GOBS of power and never had problems with them. My Brother had built some 5 1/4" two ways using generic car stereo speakers that cost him about $40 total. He drove these with 200 wpc and throttled them on a daily basis playing "metal" and hard rock at very high SPL's. He did this for months and months and never had a problem.

In both cases ( his and mine ), we are talking nothing less than sheer physical and electrical abuse. If a commercially built product can't take what i would consider "normal" use, it is either built using parts that are below a "very generic" level, the designer has NO idea what they are doing or a combo of the two.

Russ 1: I agree that the lack of a center speaker CAN work better in many systems. This will depend on the mains being used, how far apart they are, the seated listening distance, if everybody is sitting in the "sweet spot", how the source is recorded / mixed, etc...

It is not uncommon for a center channel to corrupt the presentation. This is especially true if someone is running good sized mains and only has them spaced apart by 6 - 8 feet or so. I've seen WAY too many installations like this. I think that too many people are "fooled" into thinking that they "need" a center from looking at advertising and listening to money-hungry sales people.

In my particular installation my mains are over 12' apart, so a center channel does help to anchor dialogue in movies. At the same time, side to side special effects are more pronounced due to the wider spread of the speakers. If the speakers were a few feet closer, i wouldn't bother with a center. This is one of those things that is system / room dependent. Even if one doesn't have a dedicated HT room or system, just watching movies in stereo with "decent" speakers spaced a bit apart is a BIG improvement in most cases. Sean
