Dayton 6.5" classic 295-305 $13/each

[jimbag]

Has anyone used these in a line array? I would like opinions of how they sound compared to others in the price range.
I am considering 8 on each side, using active c/o, in sealed cabs, from 80 - ~2500hz.

2.5kHz is pushing it IMHO; I'd cross these no higher than 2 kHz, as Wayne J did. Unfortunately, that makes tweeter selection problematic. At $13 they're a steal, though.

Any reason why you want to run them sealed? Almost all designs I've seen use them vented. You should be able to get a LOT of bass out of a line of 8 of them; that's the equivalent of the cone area of a 15" woofer.

The DA175 is superior and only costs $16 now. Ignore that 88 dBsensitivity figure. Look at the graph and you will see that it is more like 84 dB except in break up peaks which you certainly do not want.

Thanks for responding.

I'll be using 2 18's for subs so no reason for the larger ported enclosures.

I am looking at 2.5khz because I'm using 4 Dayton PT2B-8 planar tweeters with a 4th order c/o. I plan on getting 4 more for better vertical coverage. They sound great until you stand up.

Right now I have the Vifa made Infinity buyouts that were $14 each, (299-493) 4 on each side.

I was just hoping that being the same price they might compare since I didn't buy enough of the Vifa's when PE had them.

I wasn't really looking into the sensitivity of them because of the quantity on each side and having more than enough power. I guess the price is what got me to thinking of making some bigger arrays.

Can you give us the whole channel?

How many tweeters, and what, how many mids and what, what the crossover is, and whether you are using electronic crossovers? How far away is the listening area?

Have you read Jim Griffin's white paper on nearfield home line arrays?

I don't think that four planars is enough to put you in the nearfield for the listening area. If you're crossing over to a woofer then its not necessary for you to use a big 6.5 for the mids, which will allow you more flexibility in the mid to tweeter cross, and more detail in the midrange arena.

It's not really the reason for extension with the 6.5" classic. It works better in vented/PR enclosures. The EBP (Fs/Qes)is almost ideal for vented apps. Around 100 is ideal vented, below 50 is sealed. Between 50 and 100 is usually workable as either.

With 8 PT2 per side, I think Jim Griffin ran them at 2.2k. I agree with the other dude, 2.5k is too high for the 6.5" classic, 2k is better.

Array designs in home environments operate in the nearfield. All point source speakers, and all arrays in halls operate in the farfield.

This is sort of like the difference between physics in the macro world and physics in the sub atomic particle world.

In the far field everything blends together and you have lots of options, and also the freedom to do lots of different things.

But when your listening environment is in the nearfield, then you have to follow certain characteristics more religiously such as c-to-c spacing, crossovers, the length of the lines themselves, horizontal c-to-c, etc. You have to pay more attention to things you just don't need to worry about with point source speakers. As such your choice of speakers tends to interdepend more than in the point source world. And crossovers tend to be more complicated. Most array designers don't even venture there, and just avoid it by using electronic crossovers.

Iwould also suggest the da175, it won't cross any higher than the classic, but it is a much better sounding woofer.
