Ahh sorry I didnt notice that been a while since I read the thread from the beginning.

Ok that looks solid for my use. We'll be inside +-20 degrees in the couch. Maybe on occasion we'll use our outer positions they would still be inside 45 degrees.

To obtain a clean front look I thought about adding a sub below and extending the baffle to 52". I saw mention of recommended ear height but at 15' listening distance +- a few degrees won't matter?

To match the 1099 should I am for a high sensitivity woofer? Looking at either AE TD10 or audiotechnology 10" with sandwich cone.

Like an MBM? On the floor as a stand? I'd want about 94db minimum if on the floor.

As a stand but integrated into the whole speaker and baffle. So same width and high enough that the mid/wg is at earlevel. So I figure basicly it's another "cube" at the bottom.

Guess the TD10H is best suited then also cheaper and doesnt need alot of space/volume.

I would think you need more output than the AE 10" for the purpose of an mbm to really outshine the 2 tens in the 1099 to begin with.

Thanks Tux but I just went through FatShaft's thread and there is more than enough information to complete the crossovers. I'm about to get started.

MBM = midbass module right?

The purpose is to extent the 1099 from 80hz down to 20hz in room response. From what I read about the 1099 it's build to cross over to subs. I'm just adding a sub at the bottom integrated due to WAF and the wish to play music fullrange with having to turn on my other 6 subwoofers along with their respective 3 Pro amps.

Also it would look more like a high tower speaker and well I think it will look cool:-)

I was also asking for woofer recommendations to extend the few last octaves:-)

It sounds like exactly what BassThatHz did. He just took the SEOS design and added 2 Ultimax's to it.

Don't see why you can't just add a sub to the bottom of the tower in it's own separate chamber why not?

My concern would be not getting enough sub output from a 10 inch sub. I think BassThatHz's strategy of 2 Ultimax 15s is the most desirable personally, but I will always pick more subs+bigger subs if I see it lol.

To me they are perfect from 80HZ up.
I did numerous tests at full range...they still sound pretty good full range but I DO NOT recommend them FR.
Crossed at 80 or higher is f**ken awesome!

I agree with that. If i am creative I can manage 1.5 c.f. for the sub module. With a 12.5" baffle I am pretty much limited to a ported 10"?

Awesome:-)

For HT I have plenty of subpower I really just want to run some fullrange stereo with minimal gear online. Hey I'm trying to be environmentally friendly here!:-)

I was confused, I understand what you're trying to do now and yes mbm = midbass module.

Ah ok. English isn't my first language so maybe I wasn't clear enough in my initial describtion.

I noticed other builders of the 1099 adding stands or empty cabinet space below and it seemed like a perfect opportunity to squeze in another woofer!

If you already have the 1099 parts then yes I guess so.

Or you could go with a Tempest Build and add in 2 subs instead =D. Or go with a Fusion Sentinel Build with subs beneath as well.

Maybe the 10 inch sub will be enough, but I would HATE to be disappointed and if you're going to go with subs in your tower speaker, you might as well go big! That's my reasoning anyway, I'm sure the 10 inch sub would work I'm just not sure how much output you're going to get with it.

As to whether or not a single 10" sub in each tower will be sufficient, It will depend on how big of a room he has these speakers in. If the room is small to medium sized, then a pair of quality 10" subs may be ok, but, if the room is big, then I would assume that it would not be optimal.

Have you considered mounting a larger sub, say...a 15" on the sides of the 1099 enclosure a la Definitive Technology BP-2000 style instead of mounting on the front baffle? I am not sure of the cabinet specs for the 1099, but. I am sure that you could play with the volume in order to get where you need to go'

Yes that would be unfortunate I suppose. I guess I'll just have to try it out and see. For music I do not think it will be a problem and for movies my other subs will be available.

I always have the option to couple in more subs if the 1099 add on bottom sub isn't sufficient.

Thats a good idea and I thought about that. I had a silly dream of building curves cabinets so mounting on the side would be challenging although not impossible. Rockport does it However a 15" requires alot more cabinet volume and then keeping the baffle width intact would require a quite deep cabinet. I would be approaching SEOS-Maximus size and then I might as well go all in!

As I just wrote in the previous reply I think an addon 10" subs for music duty will be ok? I don't listen to insane levels with music, although I might with a clean sounding 1099??

At any rate, I need to raise the 1099 by 12-15 inches so instead of just making a stand I could put in a sub and try it out. Also I would be able to distribute some bassresponse in the room this way for possibly smoother seat to seat variation across our couch.

That's what I am going to try. I will have four smaller ported sub's and on the two front ones will be fusion 15's. I am going to do a curved build for the sentinels.

Hey Donny, am curious; what made you go with the Sentinels before hearing the 1099s at JBrowns GTG?. Just wondering as these two speakers have my interest.

I haven't bought the sentinels yet. Tallest I can go on top of my sub is 32" I just don't have room for towers and sub's separate in my living room. The 1099 are too tall. If I just love them I could maybe go with 1096.

I change my mind a lot so who knows. One week I have this plan and then the next another idea. In my messaging with mtg90 the v2 of sentinels sound exactly what I want at my price point. Can only go up to 450 max for each front.

Thanks, Donny, looking forward to hearing your thoughts on the 1099s at the GTG. Pity you won't have a couple V2 Sents to compare them to. I think Erich mentioned that the V2 Sents might even be a bit less than the V1s, so you shouldn't have anything to worry about, insofar as your "max" is concerned anyway.

I'm sure the 1099's will be awesome. If I had the dough I would just buy the jtrs 228 but don't have that kind of scratch. I will try to give you a flavour as I am sure several others will.

I've been drooling over some noesis 212s forever but I'll probably never be able to afford them. Thankfully, the SEOS kits can get me within acceptable proximity to sonic bliss.

If you're tight for space, Why not Fusion 8 MTM chalugadp? Isn't that your center? And you like that...

It has really weak midbass 60-100hz but more important I am replacing my mtm with the cinema 88 with 15" seos. My wife has hearing aids and I think the 88 will help with dialogue. I have always wanted beefy mains ( never had a pair). Then I will have all seos 15 up front. Plan is in jello at this point. I think I have upgradreitis, its a disease isn't it

Ah gotcha. The special 88 will probably do speech better. Output will be about the same though. If you have big L and R you'll have punch.

Don't forget you can always eq midbass into the speaker unless you are output limited.

Which would make a better center for the Maximus-18 that EricH is currently building: 1099 or 88 special??
Probably neither...

Well it's something to consider because that would probably work with my time line for building some new speakers.
