I have a pair of Hi-Vi M8a 8" bass-midrange speakers and I need to pick up a pair of tweets.

Here is what I have for the 8"s can you recommend any tweet around 50 each that would work well with this (note i really don't like treble loud) maybe a planar tweeter are those any good?

Nom imped 8ohm
Fs 33
Sens 88
Qms 4.59
Qes .49
Qts .44
Vas 42.3L

thanks guys

I appreciate that!

Would you say that it is better to have a lower end product from a higher end company or the other way around. From what I recall about morel I won't be able to afford anything too far up on their list.

thanks,

Those tweeters would probably work pretty good.  They have high power ratings because of the ferrofluid in the voice coil, it dramatically increases cooling and raises thermal power handling.  I've played with the Morel tweeters before, they are hard to mess up....

good to hear about those morel's but if you have any recommendations that would be better for the money by all means let me know.

About 100 should be fine to spend but I can't really go too much above that.

Am I corret to expect spending about another 50 in crossover parts, etc for the pair?

and can I hire you to help me make a schematic for the cross over?

Unless you know of any tweet better than that morel for the cost I'l go with the morel, but I'm open to suggestions (I won't get mad if you rec something I don't wind up liking thats not your fault, and I'm sure you wouldn't rec anything shitty on purpose).

I would prefer to save myself the 20 bucks and order them through you, if thats okay. I can do paypal or send you a check (I don't know if I'm going out to where you are anytime soon).

If the morel is the best choice in your opinion you can go ahead and order it and I'll pay you but if you don't want to do that ahead of payment I understand. Just give me an email to paypal or an address to send a check to.

Anything else I should order at the same time? Xover parts etc.

thanks again,

bryan

Hey, I was looking and I think I found an even better tweeter for you for alot cheaper.  The Vifa XT25T630-04 dual ring radiator tweeter would be ideal for crossing over low to your 8.  It has been used in MANY high end designs similar to what you want to do.  I can get it for a price ridiculously low, I'll PM you the price.  I think this would be ideal for your set-up.

I think we could easily make a crossover for this.  And it could be a very simple crossover.

Right on! I'll call you tomorrow, thanks man.

And I sold my first house on Jan 20th!

"So I've read a bunch of articles from The Audio Critic's webzine and hardcopy and they keep ranting about how nobody can actually hear the difference between amplifiers as long as they are not clipping and they are level matched.

I believed this because they guys that write that mag typically hold Phd.s and have far more experience than I do. But after listening to my new separate 2way system on Mike's amp (very nice) and my amp (11yr old Kenwood from best buy) there is such a blinding difference it was astonishing."


Mike has a one helluva nice homebrew SS amp........the first time I seen that amp I about pissed myself. Very impressed with the craftsmanship involved.

There is way too many amplifier topologies out there to say they all sound the same. Even level matched and not clipping.

They all have some sort of sonic signature.

Compare my 6 watt 2A3 single-ended triode amp with no feedback to Mike's homebrew solid state amp.
There is going to be differences in sonic signature, even if they are level matched.

Speaker sensitivity/efficiency comes into play, as well as amplifier damping factor.

My SET amp would more than likely pinch up pretty quick on Mike's speakers, with a lack of bass due to lower damping factor.

OTOH, Mike's amplifier on my old Klipsch cornwalls might however sound shouty on the mids and top end, and possibly boomy. (Cornwall's are rather big resonate boxes....)
You never know until one actually tries it.

The SET amp on the Klipsch speakers sounds nice and open, airy with enough bass to suit me fine with my small abode.

Depending on the recording....granted a shitty recorded CD doesn't really fly at all too well, but I have CD's that are recorded well enough to really boogie enough to leave the subwoofers turned off.

It's a compromise/system/room size integration thing I suppose.......

SET amp's ain't for everyone.......Mike agrees they sound rather nice, but once you get a few beers in ya and want to crank it up you are fucked......
