now that i know about speakers, biwiring etc.

should i get another one and bi wire my speakers to the two amps?

i hope you can tell from the above that i dont' know what the hell im' talking about.

i just thought two amps means more power yah?

what do i need to do to my powerwave to make it rock the casbah?

and by that i mean work with my wharfedale diamond 7.2s?

Wharfedale Diamond 7.2's aren't biwireable.
If you're dissatisfied with the sound, the only alternative I can think of is a powered subwoofer for more bass (there's a limit to how much bass a 5 inch "woofer" can produce). I'm not a fan though of cheap subwoofers, so I'm not sure this alternative is a good audiophile solution. Maybe you could borrow someone else's sub to see if it improves your system???

I diy'd a sub to add to my system. Oomph.

just one powerwave?

I can't speak for ooheadsoo, but I suspect his sub is self-powered somehow.
Parts Express has some sub amps for the DIYer--

I can't imagine the 15 watts of a Powerwave would be enough to drive a woofer of much size. With the sub amp

the PowerWave COULD be wired to the sub amp and the Diamonds connected to the binding posts on the sub amp: the Wave's 15 watts would then be powering the Diamonds AND supplying the musical signal to the sub amp. The sub amp's 250 watts would only power the subwoofer (125 Hz and below).

Yeah, my sub is self powered. Sorry for the confusion. It's not a cheap solution. I think a preamp could help you in the dynamics department too.

Your question about adding the second PowerWave for more power to "rock the Casbah" might have gotten us thinking along the subwoofer line.
If you find the Wharfedales OK sonically, don't worry, be happy.
You MIGHT even be worse off if you only add an inexpensive subwoofer,.

i guess i meant, will it be loud enough?

ooheadsoo · « **Reply #9 on:** 13 May 2004, 01:21 am »

Are you saying that you haven't tried the powerwave yet and aren't sure that it's going to be loud enough?

For reference, I had a NAD 3220 20wpc amp at one point and it drove my psb image 2b's just as well as my NAD 3300 65wpc amp did, for my purposes anyway. You probably won't be able to drown out 20 loud mouths crammed into a dorm room with it, but I'd be pretty impressed if you could cram 20 people into a room and still have a good time.

You would be surprised how little power most speakers need when you have a powered sub.

90% of the power requirements in music are below 300 Hz.

I remember trying a hookup to measure the power delivered to your speakers. I can't remember the details now but I hooked up my digital multimeter to the speaker connections of my old Magnepan 2.5Rs. They were always known as power hungry. I cranked it up as loud as I could stand in a very large living room (Beach Boys if I recall) and the power requirements based on a calculation from the multimeter readings was something like 20W.

Speaking of Subs. I have kind of a dumb question. Where is the best place to put the subwoofer? Right now I have it in a corner about 2.5 feet behind my front right speaker. It is basically next to my audio rack. I had a buddy over and he told me to put it clear at the back of the room. By the way, it is just a two channel setup, no surround sound.

Sleepkyng, sorry to HIJACK another of your posts..., but I wanted to chime in on this sub question.

I had my Nakamichi sub in the front corner of the room also, but switched it to the center of the rear of the room - essentially directly behind the listening chair, but an equal distance from me, as the main speakers.

For me, this is better, having reset the phase, crossover, and levels.

For you, it is tough to say - MANY say that the sub should be right where you have it - others no - if it is not too big, and you feel like playing with it, move it around, and see what you think.
