I like my music loud and my HT can't sustain the SPLs.
Room is appx. 12 X 12 and open on one end, behind the listening position to another room. Because of the home layout, this can't change.
I sit about 8? from the TV. I calibrated the receiver with the mic from the listening position, I am using 5.1 and watching DVDs of different bands. Speakers are rated at least twice the power my receiver and or amp can put out.

Blew all but the sub in one main speaker with Sweet Child O? Mine.
Had the speaker repaired and removed the Parasound amp.
Just tripped the thermal overload in the receiver with Stranglehold. It sounded so good it was giving me chills before the snafu.
Air flow across components is fine and receiver was not hot.
What am I doing wrong?

Specs:
Main Speakers: Def Tech BP 2006 TL rated @ 250 watts
Center Channel: Def Tech CLR 2300 rated @ 250 watts
Surrounds: Def Tech BPX rated @ 350 watts
Receiver: Denon AVR 3805 rated @ 110 watts
Amp: Parasound HCA 1000 @ 125 watts RMS x 2 @ 8 Ohms
TV: Panasonic TH-50PX500U
Interconnects: AudioQuest


Disclaimer for the dweebs: I never said any of this was funny.

A guy at work is a guitarist. He said the Nuge sucks. I asked him to bring his guitar in and play Stranglehold for me. He was embarrassed because he couldn't play it.

Hmm, I can max my Harmon Kardon AVR-500 on volume with my Klipsch RF-3's with no distortion. My ears can't handle it though...

Edit-Sorry, I don't know how to help you with your problem...hope you get it figured out though.

Do you have an SPL meter to see how loud you're getting? I imagine it wouldn't be a problem to get the volume up to dangerous levels with the equipment you're using already. "Fixing" your problem might result in you going deaf.

His Parasound 125x2 amp is throwing out PLENTY of power. He needs more cone area.
The BP2006's only have 2x 4.5's and 2x 1" tweeters... nowhere nearly enough to fill up a good sized room with the volumes he's looking for.

If you want to stick with Def Tech's, I'd recommend the C/L/R 3000's across the front stage. They have a pair of 6.5's and a 1" tweet as well as a 10" 150w pwoered sub.
You're looking for cone area, and the more the better for SPL.

The Kuze array from partsexpress would do QUITE nicely though ;)
Finding a center to match would be slightly harder....

If you want to go DIY, I'd recommend the Adire HE10.1's or this kit from acoustic-visions.com: http://www.acoustic-visions.com/~acoust...s/speakers/complete_kits/kit_lcr.shtml

Actually I somehow missed that you were running the Parasound. I thought you were trying to play these all thru the 3805. To be honest I don't know that much about Def Tech's product offerings, however, I was running my KEFs (also small drivers) with a Krell then a Classe Audio 15 and they had plenty of juice to fill the room.

I tried to do the same with a stand alone Rotel amp and it just didn't have the guts (even though it was rated at 200 watts / channel)

If you are into great sound then start with a great amp. Solid state amps basically last forever (15-20 years easily), never really get outdated, and hold their market value very well.

for a less expensive fix, try a proamp like a Crown. They usually give more watts per dollar. It is possible, even if your room is small, that your listening volume is just too much for the 125 Watt amp. Also, your room is not sealed, so a lot of acoustical energy is wasted to filling the space outside of your room.

The Parasound amp is pretty nice though.... You definately do not want to use the amp section of the denon which you aren't doing in the first place anyways.

How much ventilation do you have for your amp?

It is odd that you blew more than the tweeter in the floorstanding speaker. Either you have an insane amount of distortion being produced from the amp at high volumes, or something was already wrong with the speakers.

Id check out Rotel RB-1090, or something like the crown K2.

I used to own the 1090. It is nice, but just ok. I don't know how much of an upgrade it would be over the parasound.

Don't the 2006s have an 8" 250watt "sub" also?

I agree, you are probably already plenty loud, and it's a small room.

What mode are you listening in? Direct I hope. Or are you using 5.1 stereo or surround?

the 3805 doesn't have a whole lot of power, and I think the def techs are 4 ohm speakers - harder on your amp.

So if you're melting tweeters/mids then you don't have enough power or it's just being played too loud.

The 2006's have 8" 250watt powered subs.
I have an SPL but Haven't used it. The system gets plenty loud, I just like it loud.
Listening in 5.1 on Dolby discs and direct on non 5.1 discs.
If the Def Techs are 4 OHM, then I am putting 200 watts to them. I assumed they were 8, I'll check.
There is plenty of ventilation.

well if you're trowing the termal protection, you're playing it too loud.

Also, check and double check all your wiring to make sure there are no stray strands touching each other.

The 3805 is a decent receiver, but it isn't a power amp.

Huh? I can't hear you. My ears are still ringing.
;)
The remote for the Denon has a backlight that comes on when you move it. The air moving in the room turns the backlight on. :D
I was actually getting chills down my spine from the music. :cool:

He has an amp. It's listed in the specs above but I don't really know anything about that amp...or amps in general. I just use my HT receiver to power my system.

Have you tried it without the amp?
