ls90 with 8 watt tube amp

[ohskigod]

I'm buying that little Raddii from Russ 8wpc tube push pull (a future question will be...what does push pull mean :) )

anyway, I'm looking at my currrent speakers and wondering what would be best to run with it.

I have a pair of B&W DH550 bookshelves I am currently usinf with my Dodd pre and Sonic impact amp (dont laugh, this rig sounds surprisingly good, but no low end). Since the Radii will replace the sonic inpact, the B&W's are obviously on the list, but at 86db efficiancy, I know I can do better

I also have RT55's and LS90's, would it be kosher to use them, they actually have higher efficiency ratings but are bigger speakers, any comments as to wether it will be kosher or not?

[cmy330go]

I would think the RT55s would be the best of the 3 since they have the highest efficiency and are still a smaller speaker. I would think the LS90s and the B&Ws would be about a toss up. But I wouldn't be afraid to try any of them. I think it's amazing what little amps like that can do.

Just my .02 worth.
Congrats and ENJOY!

rt55 smaller and more efficient is a good point. and easier to carry into my basement :D

sounds like an plan, at least to start. thanx

Spend more money.

One of my goals is to build a SET rig using these unless some peep beats me to it. Then I will just build something else.!!

I'd try em all and see which does the best job. Don't always look at the specs.

OUCH!

I am considersing a possible DIY project, high efficiency full range driver speaker someday :)

just out of boredom you can count on it :D

Damn, dude... don't buy those! Go to madisound, pick up the drivers brand new for $160 and build some better cabinets yourself. If nothing else, they're using the wrong drivers for a bass reflex- those are FE206's which are good for BL horns, TL's and Voight pipes.

EDIT:
Ok, so fostex does have plans for them in a bass reflex- It's the sigmas that won't work well there...

I found my SDA1Cs to sound much better on my ASL AV20s than my RT55s. The 55s pulled much more out of the amp than the bigger box speakers. I would hook them up to everything you own, even the Amazings to hear what the low wattage can do. We rarely get the chance anymore to see how tube power can be different and the right match can be lots of fun. I think the synergy of a tube amp with right speakers makes more difference than with solid state.

[ohskigod]

sounds like a plan

those fostex plans look interesting too, might be a project for down the road. ah, but let me get the amp in the door first :)

[unc2701]

Yeah, the Fostex are fun to play with- They'll go every bit as loud as my LSi's but do it on only 80 watts. They're ideal for low powered tubes...

Everything I've done has been ugly as hell MDF, but they sound great- especially female vocals.

[ohskigod]

dude, i'm all about lookin ugly as hell but sounding great when it comes to my DIY projects :p

[unc2701]

If I get sick of playing with these Fostex's I'll be sure to pass them on to the forum- Right now I've got the 8" ones in my sig, plus the FE168 sigma's that only work in BL horns. At some point the wife is gonna get sick of it :)

[dragon1952]

The LS90's are pretty efficient and they only use 6 1/2" drivers so I think you'd be fine with those.

Not worth the chance, you'd probably cook that amp. Tha Amazings or that amp are will suffer dearly...

Just curious...but why?

[Dennis Gardner]

They are real tough impedance loads to drive..........

[amulford]

Well, the Amazings are power hungry. REAL power hungry.

Trying to get them to perform will probably overdrive the amp, and distort. If the distortion doesn't kill the ribbons, it won't drive eight 12 inch woofers...

the platinums are 8 ohms, but they still require alot of power to get em moving. sometimes it seems like my carver 4.0 works real hard during certain parts of music, the power meters really start dancin
