I'm confused


I like to spend time on Audiogon to educate myself. However, the more I educate myself, the more confuse I get. That shows how novel I am.

Here is my case. I have 7 power-hungry speakers with handling power from 50-250watt. Due to small room size (12'X13'), my current HT set up 5.1 Thinking 90wpc is sufficient, I received a free used Denon 2802 as a gift. My AVR got clip once when I was watching Tears From the Sun too loud. I learned that b/c 90wpc was not continuously power driven, the true wpc could get reduced substantially. So here are my options below.

1) Get 7-channel amp (100 - 200wpc) to go w/ current Denon AVR. Cons: some body said that I am better off saving my $ by using the amp from current AVR since multichannel amp is not any better. Is this true?

2) Use my current AVR or upgrade to better, more powerful one since multi-channel does not add much value to the quality of sound compared to the amount of money added. Cons: Sound quality?

3) Get 2-channel amp to drive main speakers during stereo mode. Get additional 3-channel amp to drive center and side rear speakers. In the future, get additional 2 channel to complete the 7.1 setup. Cons: really limited space, really excessive generated heat, and really expensive.

4) Go separate like the Outlaw combo -- 7X200wpc amp and a separate preamp/processor for ~ $2400. Cons: entry preamp/processor won't make a difference compared to other higher-end preamp/proc? Moreover, I can get a better quality pre-own combo for less amount of money, and if so DOES THE WPC ON PREAMP/PROC HAVE TO MATCH W/ WPC ON MULTI-CHANNEL AMP?

Even though the info provided is very limited, if you were me, which option would you pick and explain why you pick such option or eliminate others. I'm new to this, so I'm all ears. Each response got my full, undivided attention.

Gunbei: My HT system consists of "large" speakers i.e. the mains have dual 12's and an 8", the center has dual 8's in a large box, the rears have two 10's and an 8", etc... As such, i've not had to tinker with various settings. With that in mind, the simple but elegant solution that you arrived at was initially out of my scope. That is, i never use those controls so i never thought about them. : )

Your suggestion to Lej regarding filter settings is right on the money. Hopefully he'll try that and be able to obtain a happy medium between fullness of sound and the SPL's that he desires. Sean

Hey Marty, I wish 2 channels was easier, hahah! I'm finding it to be way more expensive as well!

Sean, your discussions always seemed to center around 2 channel and I never considered you might have an HT system. What kind of gear are you running? Your main speakers with built -in 8s and 12s is exactly the example of speakers that I was searching for that should be set to large. I use little NHT SuperOnes and SuperZeros, so setting them to small is optimal, but I have experimented with setting them to large just for fun.

It's interesting that your center channel has two 8s and that your rears have 8s and 10s. I've read about many systems including magazine reviewer's own systems that employ subs to operate in tandem with all their speakers EXCEPT the center channel. And I'm not just talking about multiple LFE subs, but one integrated with each speaker via its own crossover network. I've read explanations on why the center channel is excluded from this, but never truly understood why. Your system seems to mirror this philosophy in a way except that the "subs" are built into each cabinet, except the center channel. I hope this is another area you can help enlighten me, hahah.
Gunbei: Are you green with an odd shaped head and hang around with a horse named "Pokey" ? Oh, nevermind. Wrong fictional guy, similar name... : )

As for my center channel, the cabinet is quite large at appr 4 cu ft. This is an obvious advantage when it comes to bass reproduction as you probably know. As such, the "little" pair of 8's can do 30 Hz quite well ). The fact that they are only running up to 1.2 KHz allows them to make pretty long excursions without muddying things up.

As for LFE subs, i've been experimenting in that department a bit. I typically run two independent subs with each one housing a downloaded 12" driver. These drivers are identical to those found in the mains. As to why i downloaded them, this helps to reduce the audibility of distortion, reduces the effects of localization, increases spl capacity, lowers the cut-off frequency of the driver, increases "earthquake effects" via floor transmissions, etc... The drawbacks of downloading are that it reduces power handling and stresses the suspension of the driver to a great extent.

All speakers in this system are of a sealed design ( the ONLY way to fly ). The mains are solid down to 23 Hz with a Q of .5, the center is solid down to about 32 Hz with a Q of .7 and the rears are solid down to 27 Hz with a Q of .65 or so. If someone reading this knows anything about interpreting speaker specs, they would instantly know that i am a big fan of very tight, well controlled bass. Ported or passive radiator "slop" is not allowed in my house ( just kidding ) : )

As far as amplification goes, the two mains are being fed 1200 wpc ( actually measured at 1480 wpc @ clipping ) and the center, surrounds and each sub are fed 800+ wpc. These ratings are based on the nominal 4 ohm load that each speaker presents to the various amplifier channels.

As far as my responses primarily concentrating on 2 channel, i have four 2 channel systems and 1 HT system. You tell me what is more important ??? : ) Sean

Sean, I'm a little more yellow than green. I have a wedged head but not on one side, it's more in the front. I don't know any fellow named Pokey, but I do whiz around on one foot with the other one lifted behind me.

FOUR 2 channel systems??!!!! Wow.
Yup, 2 channel is a beyatch compared to home theater. We should rename this website "masochistgon".

Atleast, I am done for now. I haven't changed a thing since June. I will laugh at the rest of you guys.
