I'm not really sure what the sensitivity would be on a sealed back Volt-6 woofer. Probably not 97db unless they made some slight changes to the surround and cone. Those 3 way coaxial designs were talked about a few years ago but I don't know if people want something like that or not. I've already named them in my head.

Erich - I remember you saying once that part of the issue with the 893s was that people didn't leave many reviews for them. If you end up putting the 893 back online I will most definitely write up a positive review on your site, because I think mine are awesome.

That might be a lot of design work to save about 1.25" of height.

I'm wondering how much real world difference I would see, comparing my old 893 center to the new arrangement. And I would like it better if the ports were at the back or ends.

My problem is that I built a very nice TV stand with 10.5" for the center... Yeah, I know - sucks to be me..

I GOT IT!

Instead of a 3 way,why not just build an 88 Special with the woofers on either side of the waveguide. The baffle could be 9 X 34" and the box only needs to be 8.3" deep. I wonder how it would blend with my 893 towers, though.

The size and position of the woofers was selected to give a similar off-axis response as the 15 inch waveguide. Moving them farther apart would drastically change off-axis response. They would sound just about the same directly in front of the speaker, but if you're always centered in front of your tv you might as well just use a phantom center channel.

The reason you can't put two 8" woofers on the sides of the SEOS-15 is because the center to center spacing on the woofers would be too wide of a distance. You'd get comb filtering issues unless you lower the crossover point well under 1000hz. The problem is that a tweeter or compression driver can't handle a crossover point low enough to do that, which is why a midrange has to be added and the speaker turns in to a 3-way.

I have Fusion-15s as my LR and have been trying to figure out a good solution for a center channel. If the new version of the Fusion-8 swapped out the EOS waveguide for the SEOS, I think that would be a great upgrade that would make them a massive hit for a lot of people, as well as a great solution for my center.

I'm not sure how the center would work out with the SEOS width, but there's a lot smarter people working on these designs than I.

Yeah, I tried to find the difference in width between the EOS-8 and SEOS-8, but couldn't find the width of the EOS-8 anywhere. Can someone measure theirs?

I wish I could fit another F15 or 88 special, and match the SEOS-15, but I can't

I have almost 13" of height available, so I could technically fit the 1099 center, or the upcoming HT1010 center with the square waveguide, but I'd actually prefer a design that's around 10" high so I can pick the speaker up 2-3" and get better clearance without obstruction when I am fully reclined. This is why I was feeling like a SEOS-8 design would be pretty much perfect, and the EOS-8 and SEOS-8 seem to be pretty close in width based only on photos, so not a perfect comparison.

Can anyone tell me what the crossover freq is on the Fusion-8?

Fusion 8 is around 2,300 to 2,500Hz. The proposed "898" would be around 11.25" tall and bring the sexy back with the SEOS 8 and cross over around 1,700Hz. Buy six of them, they're small! If you really want small, light weight and 93.5 1w/1m efficiency (almost the same as the Fusion 8) the HTM 6 might be an option. I think it weighs around 13 pounds so an easy load for those speaker hanger thingies.

Just trying to help you spend your money is all--I also have an 88 Special for a center but my wife was not too wild about the oven grills so I made cloth magnetic type. I'm not worthy but I try.

EOS-8 is approximately 7-7/8" x 5-7/8"

SEOS is approximately 8-1/4" x 4-1/2"

Even on the MTM center? Doesn't that frequency seem awfully high for the woofer center-to-center spacing that I'm guessing is close to 16"?

Thanks Matt! It would seem that extra 3/8" of width wouldn't be a deal-breaker on a revamped SEOS-8 based Fusion-8 Is that the plan? If not, is there a reason it wouldn't be a good idea?

You wanted the center? OK, that one is at 1,400 Hz. You'd have to ask Matt what the SEOS 8 loads down to, he would know the answer to that. It works in the HTM-6 to 1,600 Hz with the HTM compression driver, below that I am clueless. Hope that helps.

The 88 Special crosses at 950Hz. How close do the woofs need to be, c to c for that to work?

When I got my Fusion 10s I eyeballed the 893s HARD. The deciding factor in my case was the math on wattage required for my room to hit reference on them, and the price I got my fusions for.

The 893 would've needed external amplification in my room. The fusion 10s I could run on just my AVR. That 5dB difference makes all the difference in the world there. I honestly think that was the main thing that held back the 893.

I know, silly reason to make a decision, but I budget myself pretty hard core. Keeps me from falling too far down the rabbit hole, and I got too many family expenses to switch gear as often as people here manage to do.

There was also a design started with a coaxial flanked by two 8" woofers, but I don't think the chosen parts matched up as good as we hoped and the project was put on hold.
I felt given the price it was very close to the 1099, and that it was only necessary if you really needed to save those couple of inches.
The Cinema 8 looked like the better "deal" There was also the Alchemy 8 tower, so there was already a herd of speakers in a similar woofer /form factor, that it would make the volume lower than only offering one speaker in that space range.

Since we don't have the numbers, you really have the best insight as to EXACTLY what we're looking for. Otherwise, we're just making inputs on "not very often" which could be a whole range of numbers to a person without the data.

Given that speakers are already being taken down for lack of orders, I'll be the person to kill the party and say that focusing on narrowing down the speakers to the main speaker lines first would be the most beneficial.
Focusing on the SEOS speakers, cutting down the number of the DIY Home audio kits to a core lineup, and then adding a couple of SEOS designs that you feel are highly clammored for will help you.
Otherwise, lots of options makes people indecisive, and especially when many of the recommendations cluster around the same options, it's hurting more than helping.
Here is one study on this:
Quote:
The Famous Marketing Study About Too Many Choices
Here’s how the study worked:

Sheena Iyengar from Columbia University set up a table laden with jams outside of an upscale grocery store in Menlo Park, CA. Over a period of two consecutive Saturdays, research assistants dressed up as store employees and offered samples of either 6 or 24 flavors of Wilkin and Sons Jams, a British jelly purveyor known for exotic flavors.

Prior to this study, the common marketing theory was that more choices are better for customers. People like more options, so providing more flavors should lead to more sales.

The results from this study proved otherwise.

During the time periods when 24 flavors were offered, 60% of people stopped to sample the jams, compared to 40% when only 6 flavors were offered. These numbers seem in favor of more choices, but the important question is this: which group purchased more?

Of the customers who sampled 24 flavors, only 3% purchased, but of the customers who sampled 6, 30% did the same.

If you run those numbers based on 100 people, 60 would stop when 24 flavors were offered, but less than 2 purchase (1.8 to be exact). When 6 flavors were sampled, 40 stopped at the table, and 12 purchased.

Which table would you want your products to be on?
taken from:https://neilpatel.com/blog/too-many-choices/
(not a flower of the website, just know of the concept from various business readings
It's also part of Apple's success. Compare the number of models Apple offers to any other company.

This allows you Eric H PERSONALLY to do two things:
Simplifies your life and doesn't stretch you thin.
Lets you focus on delivering the kits you know will bring people the most joy.

A 30-50% reduction in number of offerings, but I could never be exactly certain of that without hard data.

Just my no fun for me honest view.

When I mention that some of the kits don't sell very often, it varies. And it doesn't seem to matter what size the speakers are or how expensive. For example, the Maximus-12 has been on the site for about 4 years. I'm thinking around 10-12 have ever been built. That's like one order per year. People seemed to really want a design like that and there was also a cheaper model done that used the Beta-8 and DNA-205. The cheaper one was on the site for about 1.5 years but no one ever built it, so that came down.

Fusion-8 tower and Cinema-8: Maybe a total of 50 cabinets originally made. Took over 4 years before they were all ordered. Fusion-4 and Fusion-6 didn't fair any better.

I can order more 8" woofers and flat packs for the 893 but there really won't be a way to get the 99db sensitivity rating that the thread was hoping for. Maybe they would do better on the second time around, who knows.

I’d be down for three—two vertical, one horizontal—-if they came back.

Eric, have you guys ever considered an Array?
I feel like this might be outside your websites interestes as it would require a lot of packaging and is also pretty expensive.

How many woofers would you consider are needed to consider it an array?


On the 893, the absolute minimum order on the 8" woofers is 100pcs but the price is kind of high when that few are ordered. I can contact Eminence and get a current price and see what they can do.

I know the F4 is considered an array with the 4 woofers but I was meaning more like a full array with both LF and HF. Something along the line of 5-8ft tall. I'm not asking because I'm recommending it (i'm not) just wondering if it was ever considered.

A couple designs have been drawn up and talked about. One used 4 woofers set up like the Quad-4 and then another using 8 different woofers and a small waveguide. The issue with the 8 woofer array is that it would probably only get down around 120-150hz. So it needs a midbass module. Once you do that, the price jumps up quite a bit and then you have a center channel size issue with the midbass woofers.



There are ways to get to 99db for the 8" model, but the overall design looks a bit funky, untested, and not much like the 1099 layout. Basically from left to right:
woofer - 1099 mid - square waveguide - 1099 mid - woofer


I've got a drawing somewhere and will dig it up.

A few misc. ramblings from the peanut gallery when it comes to line arrays.

Back in Feb 2012 to July 2013, I built a pair of line arrays of my very own--and they do work--eventually. They ended up being 3-way vertical line arrays with 12 five inch woofers, 20 three inch mids and 48 tiny dome tweeters in straight boxes standing 6 feet, 2 inches tall. To compress the world history of vertical line arrays from the 1950's to present day, and to account for straight line, curved line (CBT) and hanging boxes to include "J array" etc--I'll make it short for once. The main rule that must be applied and you can't get out of it is the center-to-center distance must be adhered to because they will boost/cut each other, comb filter and do fun with phases when running a long line. The biggest problems start at the highs but improve as you go lower in frequency. Even with 48 tweeters stacked up with around 1.4" center-to-center distance between them, they will decouple from each other at 10KHz and fall off as the frequency increases--it don't matter if they go to 100 KHz, the output will decline because of the distance between them. I "fixed" it with a broad EQ boost at 16KHz of +6dB, if your spacing is wider than 1.4", you need even more boost.

That being said, I do like line sources--part of that is they sound very "big", have narrow vertical dispersion, high SPL capabilities and low distortion. The other reason I like them is because if I didn't, I just blew 18 months of my life and more money than I want to admit building them--denial works well for me! Those monsters were banished to the garage but I did listen to them in my house for a weekend, very interesting sound but for home use, probably not a good idea for HT.

Now Erich sneaks up behind me with a gun, puts me out in a building Breaking Bad style and I'm forced to come up with an array "kit" for DIYSG. This is how I would do it! First thing, the longer (taller) the array is the better it sounds and your typical room is 8 to 10 feet ceilings--it will be tall. This is what I would use and why. I would use the Faital Pro 3FE22 which are neodymium 3" full range drivers made specifically for line arrays and they would be my mid/tweeter section. They are 3.19 inches or slightly less from edge-to-edge of the frame when mounted. I'd make "segments" with 9 of those per "segment" wired 3 series/3 parallel and use the 16 ohm versions so each "segment" is 16 ohms. When stacked, 9 of them will be 3.25 x 9 or 29.25" tall. The box WILL be made out of 1/2" birch to a max height of 30" to limit the "seams" between segments. Two segments would be five feet tall and 8 ohms, three segments would be 7.5 feet tall to fit most rooms and ~ 6 ohms while the big daddy four segments will be a solid 4 ohms for those that have 10 feet (or taller) ceilings.

In real world testing, they will go down to 160 Hz easily and with a bit of EQ, easily go past 16KHz and are very efficient. You could use say three 8" woofers in each segment and cross them at around 350Hz so cramming them tight won't be an issue. To cut weight, I'd be looking at the neo woofers used in the HTM 8 in 4 ohms wired in series for 12 ohms each segment. This will create a 6 ohm load for two segments and a four ohm load for 3 segments in normal rooms. 9 of those Faital Pros give around 97dB of output 1w/1m so whatever 8's can do it--go with those. I bring up the Celestions because of their light weight mainly--arrays get heavy! Be aware if using 4 "segments" the bass might be down around 3 ohms so plan your amps accordingly.

In theory (where I live!) the "rule" for perfection is no more than a 1/4 spacing of the distance of the highest wavelength. For example, 10 KHz wavelength is around 1.35 inches long so if you want perfection with dome tweeters, just get ones that are 1/4th their size or around .34 inches in diameter. If you want "perfection" at 20 KHz, just get tweeters the size of 0.17 inches and stack 'em up! In reality, that is not going to happen but my stack of tweeters spaced at slightly under 1.4" apart started to roll off at 10KHz--or basically one complete wavelenght in the real world. I would assume using 3 inch full ranges as tweeters considering they would be spaced 3.25" apart would start rolling off at around 4 KHz? Faital Pro avoids this by having a mild "rising response" in SPL as it increases in frequency until around 18KHz (I think) Faital Pro specifically designed them to be used as line array drivers so it makes sense. Yes, they will start beaming, yes they will start to "decouple" with each other and yes the polars will look like a comb filter--yes it will! The "reason" they actually work without hurting the children is when they start doing their nastiness, your ears are not very sensitive to it and at over 10 KHz, your ears are very insensitive to all the sin the line array is doing. Just be aware of that going in.

The lunatics of the world that build line arrays generally hang out at the DIY Audio forum--they build straight line arrays with Vifa TG9 (I think) 3.5" full ranges, use other 2 to 4 inch full ranges, build 2 way versions or try out the hanging box PA style line arrays for fun.

Now if Erich really wanted to use those 893 woofers, I'd use six per 30" tall segment and wire three on either side of the full ranges for a 12 ohm load. They would be heavy, very wide (which is actually a good thing) and look very, very cool. Cost? $33 each at PE for the 3FE22 full ranges so purchase 18 of them to make 2 segments for the smallest line I would use but you can do two "mini arrays" for stereo for testing purposes. For each "segment" it would be 9 FRs at $300 and three Celestion Neos at $180, then the crossover at ~$50 and the bezel, flatpack, connectors and shipping for "only" $600 per "segment" For the smallest array of 2 segements each side, figure around $2,400 for the kits. Parametric EQ is a good idea so if going two channel, the PEQs from the pro side or MiniDSP gets thrown in the calculations.

This is how I scare away people from trying to duplicate my arrays, my parts are not available anymore and costs really jump when ordering crates of them. Personally, I think it would be tough to sell array kits because they are very expensive to do correctly, most people don't have experience with them in a home environment and once kits hit the thousands of dollars, most people might notice that as "real money" so pause at taking the chance.

The other downer is Erich can track me down and send me a special surprise in the mail (the ticking kind) if he gets stuck with hundreds of drivers in his already clogged up warehouse. Now if Erich wanted me to front the money to get 10 line array kits made--I would not hold my breath! It would be a fun project but as far as stocking all that stuff, I would do something like segment bezels or maybe crossovers and you buy the drivers yourself from PE. Still, just the cost to design one is pretty high so--in the long run it would not be a horse I would bet on.

The TG9 array would be the cheapest option, I think those drivers are around $12 each and if you used 16 of them, not too extreme in cost and around 6 feet tall or so. Wired 4 series/2 parallel for 16 ohms each segment and with PEQ, they can make it to 80Hz. With 3.3 inches, 8 of them wired for 16 ohms would be around 27.5 inch segments but at $12 each driver, you can play the array game with only around $200 for two "segments"--just don't forget PEQ!

https://www.parts-express.com/peerle...ofer--264-1062

If you want more exotica, Vifa also has a fiberglass cone version for $16 each.

I don't really see line arrays discussed much in these parts, they are an odd duck but if Erich just made the "segment bezels" those would be HUGE sellers IF people want line arrays. The bezel is the hardest part. The other problem is arrays and HT really don't get along--I don't have an array theater but only a pair and pondering it gives me a headache. I do wonder how those CBT arrays that Parts Express sells would sound hung upside down as surrounds--until my wife brought me back to earth. No idea what kind of volume PE does with their kits, Erich could ask them nicely about it and go from there.

In summation--I think I got lost myself! Tread lightly!

Here's the dual 5" midrange 899 idea that's 10" tall and 36" wide:
