Lonman, et. all:

I am looking into tri-amping my system and need a good suggestion for my high-freq. speakers.

I already have Yamaha S115V main cabs on top of Samson Expedition 500 subs and know it would sound better with a pretty modest investment if I took teh high freq. load off of the mains and let them just handle the mid-low and mids.

I was thinking about adding either Yamaha BR10s or Samson Resound RS10s as the high freq. speakers. The Samson is a cheaper speaker by $50 each and actually has better specs on the tweeter than the yamaha, so it may be better for this purpose. Does anyone have any other suggestions for another speaker that would sound great as a high-freq speaker?

It is important for my setup that I am able to set the high freq speaker directly on top of my Yamaha S115V mains, as my space is limited. I would take out my spacer poles and just have a full-range stack on each side of my stage.

Let me know what yall suggest!! I have also already scouted amps for the two speakers I mentioned above, but if you suggest a different speaker, please let me know which amp you run it off of as well.

BTW, I am not in the market to go nutso on this. I realize something like a Mackie SRM350 or JBL EON10 G2 would be optimal, but I don't want to drop $1200 on this upgrade when the tweeter is pretty much all that will doing the work anyway!!

Thanks!!

By introducing a 10" + power horn in your system, will have a major influency in mid and upper range.  Your Yamaha S115V main cabs do not really represent true mid frequencies, due to the fact that you have a 15" driver in there. The 15" driver tends to be muddy when it comes to mid range and the horn only represents the top spectrum of the frequencies.

As to which speakers to compliment your current system, personally I would go and test-drive them.

If you do tri-amp, get yourself some good active cross-over's.

If that is the case, then why do pretty much all QUASI 3-way systems employ 15" drivers as the woofer that is not the dedicated low woofer (i.e., the one that handles the mids)? I understand what makes them QUASI instead of true 3-ways, but then why wouldn't they imploy a smaller woofer and driver as the non-low woofer?

Is there such a thing as a PA speaker that JUST contains a HF horn??

In that case, I could add just a horn to my system, feed it about 40-50 watts of power, and let my main cabs handle MOST of its normal frequencies minus solely the highs. Is that doable?

I don't know if I understand your question 100%, but looking at a speaker, in order to have a true 3way, you obviously need 3 speakers. Making the cabinets bigger and more expensive.

The 2-ways are full range, true. But it doesn't change the fact that they don't have the dynamics of a true 3 way. The 15" is quite happily flopping around, while at the same time, you try to push the mids through.

That's why a 15, 8 and e.g. an EV horn are so much cleaner sounding that a full range 2-way. The 15 in this case is NOT the sub woofer, just a bass driver.

OK, I may have the wrong idea when it comes to triamping. Could you please breakm down for me what kinds of speakers would be in a typical triamped speaker stack??

I thought I could stack my subs to handle sublows and some lows, my yamaha S115Vs to handle upper low freq and all mids, and a smaller speaker with a good tweeter to handle the highs and get a true tri-amped sound. Why would tri-amping 3 separate speakers not be as optimal as a single tri-amped speakers?

It seems to me that if my Yamaha S115Vs were DEDICATED to the mid freqs, they wouldn't be "muddy" like you stated above. What am I not understanding?

Yep, EV makes them, propably other manus as well.

That's kinda pointless, seeing that you already have a horn in the Yamaha S115V main cabs

You don't need tri-amping. 2 amps will do the job on a full stereo stack (Of course you need proper amps). 1 Amp pushing the sub(s) and amp with active cross-over for the bass(15", NOT a sub), the midrange (8" or 10") and the (powered) horn.

Oh, don't understand me wrong, tri-amping 3 separate speakers might be as optimal as a single tri-amped speakers, but your center speaker (Yamaha S115Vs) will take away the crispyness due to the 15". Use the Yamaha S115Vs, but let them X-over at the mids. Let your top bin handle the mids. Also, you can disconnect the horn in the Yamaha S115Vs , depending on the position (hight to ear level) With the new bin on top, you might over-do your tops.

The Yamaha S115Vs cannot be dedicated to mids, because you have a 15" driver. Mids need a tight smaller driver in order to better handle the higher frequencies. The muddy part comes in that the 15" cannot respond as quickly to the high frequency changes as a smaller dedicated mids driver.

I hope this makes sence. I am terrible in explaining

The Club series can't really be bi-amped without modifying the wiring inside.

You can tri-amp with a 15" with no problem.  The 18" sub would just be taking the brunt of the low frequencies like 90 hz & lower leaving the 15" to handle 90hz - 800-1600 hz (not sure exactly, but somewhere in that range is where it's at now) with the horn handling the upper range.

Its been awhile since I thought about but find a good tutorial on it....

OK, I was on the right track and we were just speaking a different language on the actual freq. ranges to feed to each speaker.



Could you please direct me to a link for this EV product?? It may be the most efficient option to handle what I am wanting to do.

They don't make them already built into a cab??

My carpentry skills are NOT good....

Toph have you considered getting a 3 way cab in the wattage range you want then amping each one?

Yes, but then I'll have to spend even more $$$ and I'll also have $675 of prefectly good Yamaha S115V speakers sitting at home doing nothing!!

You know, I have some old speakers that I don't use anymore. Maybe I'll strip them and put a decent horn into those cabs. Sounds like a fun little project...

Oh ok I did find a 3 way set of ev speakers on ebay (just the speakers) but I couldnt find any tweeters in a seperate cab...

Looking at your original question, the high frequency load is the minimal load out of the system, what is the power robber is the low frequencies.  
You can tri-amp with your current set-up, however again, you would need an external crossover - 3 amps & rewire the S115 to bypass the internal crossover to wire each driver directly - it will be controlled via the external crossover.  Now doing this will make them bi-amp only - meaning you will never be able to hook one amp to them in full range mode (well unless you rewired everything back through the internal crossover).

LONMAN: If Given A Choice Between These 2 Speakers Which Would You Choose For Karaoke YAMAHA-SII5 CLUB SERIES (Which Are Two-Way Speakers) Or CARVIN-1584 Which Are (3-way Speakers). The More I Read It Seems To Me That 3-ways Are Better For Vocals, Is This True In Your Opinion?

Tommy,

The reason I was looking into it is it is certainly better to have a separate sound element dedicated to the vocal range than it is to have everything going through the same element at once. It just gives you many more options for improving the clarity in that range when it is not having to handle lower frequencies as well.

I have heard some horror stories about Carvin Speakers, though, so I'll leave that accessment up to Lonman
