Faital pro 8pr200 !!!

[kringle77]

Has anyone seen this driver? Good x-max, flat frequency response and flat edges that could be put in a very tight pattern. Seems like this would be great in a killer 8x8 cab.

Looks nice, on paper.

Another driver to consider, although heavier, is the Ciare NDC8-3; I have a LDS 2-8 cab with them in it that sounds amazing.

[kringle77]

I talked to Don yesterday about doing an 8x8/tweet, he had to figure out how big the cab would be. The specs appear to be better than the 10's I was looking at. It seems like a 20"wide, 40" high cab with rear porting would be a fairly small, devistating punch machine. Like a fist to chest! Has anyone else used these drivers or have any opinions on this type of cab? I understand the dispersion aspects at this point. From playing some gigs I have come to realize that horizontal dispersion is great but, when you have a packed club and the crowd is practically on top of you, the mids and treble are getting soaked up by the first few bodies. You are farther ahead to get 90% of you sound from the cab and then let the pa tops get the clarity out to the club. You can even roll all the low end off the bass channel on the pa. This is why I will be going back to my 4x10 until the next LDS cab is done.

$150 per driver thats going to be one expensive 8x8.

At $150 each that's $1200 just for the drivers. It's nice enough, but eight will have a total displacement of 1280cc, which is far less than two 3015LF. Those, along with a pair of six inch mids, will go lower, higher and louder for about $400 less scratch.
I'd call this driver a good option for someone who needs a very small 1x8 or 2x8 with decent output, as in a subway/bus user. Once you get past two drivers other options are more appealing.

[kringle77]

Well, Im going through with this cab. Bill, you are right about the 1515/66 but, that cab will never sound the way I want it too. This cab should get what Im after with very little knob turning, if any at all. It should also sound pretty good with my old svt which, never sounded that hot with any of the 3-way cabs. Don said the cab should be roughly 20w, 36h, 15.75 deep, 65-70lbs. This thing should hit like a bat to the knees and sound great doing it. Also, it will probably cost less than what it would cost me just to buy the materials. Thats a plus for sure.

If you're going to do an 8x8, please, please, please, figure some way out to make the dispersion not suck

Start with a linear 4x8 maybe?

There are some ways to fix the dispersion by crossfiring the woofers too, but I don't know all the math behind that.

[kringle77]

This is going to work for me. Yeah, crossfiring would help. A vertical cab would be better but when it comes right down to it, this design will get the job done. Most clubs I play, the band is right on the floor level with the rest of the club. The first 3 levels of bodies soak up all the highs and mids anyway. In this situation, when using in-ear monitors and using the pa, an 8x10 would be just as effective as a mid loaded cab or the like. This 8x8 will be smaller, lighter and have as much output as an 8x10. Better lows and quick. This thing should just thump.....by my interpretation of thump.

[kringle77]

It will realistically have about the same dispersion as a 1x15 cab. Better than a 4x10 though.

[koobie]

Kringle, sounds like a cool, though not inexpensive, project. Have you owned an 8x8 cab before? In any case, thanks for taking one for the team!

[kringle77]

I've played the swr 8x8 and ampeg 4x8 and like them but, those had drivers that were crap. Especially compared to these. Traynor as a cool 8x8 but that cab won't be able to tough this one in any way but price. This cab still won't cost more than an ampeg 8x10 and will out perform it.

[rpsands]

I don't see why you don't just get a vertical 4x10 with deltalites There is nothing magical about 8's except that you pay as much for a 10 and lose the only advantage (dispersion) when you stick them side by side.

Hell if you want to be hardcore, get the crazy expensive Beyma 10's.

[kringle77]

These 8's have better specs than the deltalites. The cab would be akward and tippy. There are several practical gig reasons for what Im doing. It's a compromise. A vertical stack of these 8's would have good dispersion up to around 4k. Most 6.5's start dropping harder after 2.5k. That would be in a perfect world. I've never gigged in a perfect world though.

[rpsands]

Better specs than the deltalites my butt.

58hz FS destroys your low end and the sensitivity is 92db or so (I am nearly positive if you calculate the SPL it'll be quite a bit lower). It'd take two of these per deltalite and still they'll be vastly underperforming under 100hz. And you're reading the off-axis response graph wrong. Intelligibility is gone by 3khz (-6db) though it does creep back in a little. Once you set them side by side that's meaningless though.

* You need to model this box. The FS of those drivers is too high and the sensitivity is crap (for the money). Also, with their huge xmax you're still not going to have much more vD than a deltalite.

If you're going to use an 8, the B&C 8BG51 is a much better choice (although maybe not for full range..you're going to want to cross over to a horn anyway probably)

[kringle77]

For half the price I could build a sealed 6x10 using 4 eminence B810 drivers and 2 jensen mod10-70's and probably be just as happy. Thats the kind of tone I really go after but, Im thinking that the 8x8 will have more output, go lower and higher, be alittle narrower which means alot to me going through doors. It's a tough call but Im betting the 8x8 would do everything I'll ever need it to. The sealed 6x10 is very tempting though.

[rpsands]

If you're going to mix in the mod-10's why not just use a 3015LF to replace the 4 B810s, and cross over to the Mod-10s?

Frankenstein mixing the 10s when what you really want is the sound of guitar speakers breaking up on top and nice tight bass on bottom seems self-defeating to me.

I'm going to be experimenting with a guitar 12 and a 3015LF sub here pretty soon and will let you know how it turns out.

[kringle77]

I've experimented with the 3015lf in it's own ported cab with the mod10's in a sealed cab, crossed over different ways, etc. It still doesn't sound the same as my 8x10 cab with 4 sealed chambers. It just doesn't. I literally will eat my baseball cap the day someone shows me a 3015 loaded cab that sounds the same as what Im describing. After eating my hat, I will then buy the cab from that person for whatever they want to charge. Seriously. You wouldn't believe the amount of science experiments that I have run in my basement and still not achieve that sound. There have been some really good sounds, but not the same. I've used different eq's and dsp, there are just some things that......well it just is what it is. No matter how you eq my avatar 3-way cab, YOU WILL NEVER make it sound like my sealed cab.

[kringle77]

RP, if you are experimenting, I would definitely go for the jensen mod10-70 with a 3015lf. That jensen just has the tone of an old ampeg cab. It's just just enough high end to not really need a tweet unless you are trying to get a modern slap sound, even then you can get close. At gig volume that kind of top end is just great. Works so well in a band mix.

[rpsands]

Man, you should email Duke LeJeune and tell him about your 'pay whatever price' challenge. That guy is a wizard with crossovers.

Pretty sure Passinwind has done some work with a guitar combo and a 3015LF also.

[kringle77]

YES, he is. I've played through the thunderchild and it's the best 2-way I've ever heard. PERIOD. If anyone could prove me wrong, it would be him, and I'd be happy for it. Maybe that's something he would be interested in? hint, hint
