Posted By: Syxx Question about M80ti's - 08/13/02 02:48 AM
hello im fairly new to home theater and im about to buy some new fronts and i want good ones! im getting the M80ti's, but i dont understand why does it have 2reds and 2whites for speaker connections on the back? all the ones i have ever had have just the one set, could someone explain why, and if it would work with my Kenwood VR-510 Receiver, or if i need and special wires or something.
also i should mention i am only 18 and just started getting some stuff, if you would like to know my setup im running right now thats cool. i just started this summer getting things from my part time job and computer work i do.

Thanks for your help

Those two pairs of posts are for bi-wiring/bi-amping. They are for bypassing the internal crossover and using an external one. One set is for the highs, one for the lows. The advantages are debateable but if you don't want to bi-wire them then you put a jumper between the red posts and one between the black posts and use a regular two wire cable to connect them.

thank you i think i will get them. i found them at a local audio store on sale for 800.00 Canadian!!! they look like they will rock once i get them.

Okay Syxx, let's have it, man! What retailer is mad enough to offer the M80s for only $800CDN? Are they A-stock, or blemished models? Your choice of colour? Thanks for the info! Cheers!

Yes, do tell right away. That price in U.S. Dollars is reason enough to skip the M40,50,60 dilemma I'm having and buy the 80's NOW.

Hi Syxx,

About that special speaker wire,.... you really don't need it. There have been volumes of discussion about it in this forum. If you do a search for "sreaker wire" you will see what I am talking about. If you would like some pretty good info on speaker wire, search for a post I did on 6/10/02 and go to the link in the post (Speaker Wire). I think most in this forum would recommend a good grade 12ga. vs. the $10.00 per foot material.

i would tell you but then i would have to kill you...

its a local store that is going out of business..[how sad ] so i get a nice price! i already put down 200 to hold them so i will have them in a day or 2.

i couldnt beleive the price when i seen it. they had them for 1500+tax regular and i thought that was already a nice price.

oh and i cant pick the color...but there black which will match all my others anyways. and they are A-Stock

i also noticed now that the speakers are 4ohms....how can i tell if my receiver can handle that?? btw i have a Kenwood VR-510.

Syxx,

Others here will tell you to ignore the impedance issue, your Kenwood can handle it just fine, but I'm not among them. I'd definately think twice before subjecting your receiver to that load, but again, that's just me. You've got a few options, however: you could always buy the 80s, and sell them (likely at a profit) if they're a poor match for the Kenwood. Or perhaps your super-secret dealer has a pair of M60s to sell you at a cheaper price instead (the 60s nominal impedance is 8 ohms, much less of a potential difficulty with the VR-510. Or you can live with 80s driven by the Kenwood for a time with an eye toward upgrading your receiver to a more robust model in the future (the oppurtunity of buying the 80s at this price will not likely present itself again; strike, while the iron's hot, man!).
Lastly, for pete's sake, Syxx! I understand your not caring to post the retailer's name here in the open forum, so how's about e-mailing it to me? Your choice, mate. davestrot@hotmail.com Cheers!

Hi syxx,

Nor will I tell you to ignore the 4-ohm impedance of your M80's. Look at the back panel of your Kenwood near the speaker binding posts. What does it say? Is there a switch you can move "For speakers of less than 6 ohms impedance" or it might say "For low-impedance loads--4 ohms".

It might also say "do not use speakers of less than 8 ohms (or perhaps 6 ohms)", in which case, be careful. The M80s are very sensitive, which means they'll play very loud on only a few watts of input power, but their impedance curve touches 4 ohms in a couple of places. That means lots of current will flow through your Kenwood's output transistors. Put your hand over the top of the receiver: it should never get hot (warm is okay) and be sure it's well ventilated.

If there's a switch for 4-ohm loads, that will impose some current limiting on the output stage, which is okay as long as you don't try and overdrive the Kenwood at high levels. If you do, it may just shut down until it cools, or you reduce the level. It's a protection mechanism so you don't blow your output stage.

Regards,

i would rather not say at this time...since someone might try to outbuy me!! j/k but i would rather wait until i have them in my hands. because i noticed alot of ppl on here from my area. heh. but i will let you all know in a day or 2 when i have them.

-Syxx

also i think i will test them like you said and see how they handle. afterwards i will update my receiver,

thanks all

Good enough, Syxx! That's way outta my way, anyway! (But your deposit secures your purchase, so no one could scoop you, right?) Enjoy the 80s, mate!

Cheers.
