I have had a tempest (got one in the garage right now) in a ported box. With the right power and EQ, the tumult will definitely outperform in the sealed box. Without EQ, not sure if it will hang for HT with a good ported tempest design. For me, there just is not enough good strong low end...

Thanks! I am running (16) 10's inthe suburban right now. MAn is it nice. . . I am actualy running (4) Avalanche 15's in the HT right now and it kills the (2) Tumults. Tumults were really nice, but they are expensive. I have no experience with the Adire amps. I would assume they are...

I have used both in home and car. The AVA 18 definitely sounds much better without any EQ. Does not have near the same bump in the freq. response around 60 Hz. If you have the 1803's in large ported enclosures, and you want to move to AVA 18's in small sealed enclosures, I would guess it is...

Are the sonotubes ported? Do you use an EQ? If the BP's are setup in large ported sonotubes with an EQ to flatten the response, the sealed AVA's are more than likely going to sound like a downgrade for HT. If they are both sealed without EQ in the same size enclosures, I would guess the...

I have four Avalanche 15's in my house. . Awesome subs!!! They replaced Tumults, and IMO are a better choice on a 1000 watt plate amp. If you are going to run 2000 watts per driver, better wait on the Tumult. . . Brian

Thanks. I designed the floor plan myself, so I included a 24" deep area in the front and rear of the room for built in cabinets, subs, and surrounds. Wife wanted the front mains in there too, but the wall just was not large enough when I decided to go with a 120" screen instead of a 100" screen...

I built the unlimiteds with the 9500 tweeter. Kit was $1500. I actually have mine about 6" from the back wall and think they sound great!!! I can hear a little better imaging when they are 4', but I am like you and just cannot have them 4' from the wall. My room is setup with (3) Rhythm's for...

I second the North Creek Rhythms. I have had mine about 4 years now, and I don't even think about other speakers. Well, maybe I experimented with a set of cheap line arrays, but they are gone. . . For $1000, the rhtyhm is a heck of a speaker. Brian

How will you wire the 9 drivers? I have my 12 wired from top to bottom in the (2 of 4)-3-2-3-(2 of 4) arrangement. There are 7 horns wired (2 of 4)-3-(2 of 4). My enclosure is tuned to 50 Hz. Use a sub below 50 Hz. . . Brian

My Cousin has those arrays. They were a fun project I just wanted to try. They can be built for $192.00. That included everything, even a new router bit for cuting all the holes. In my case, I actually picked up the 24 Panasonic 6.5" drivers for free, so they were only $120. They sounded ok...

No measurements yet. All I have is the RS meter, so don't know how good the measurements would be. Sure sounds sweet to my ears. :D Brian

That is why I did (4) 15's. Easy to get 2 ohms/ch, and I still only have two cabinets. (3) 18's is a stange configuration for most amps (unless you have multiple amps). How big is your room? Mine is pretty big. like 20' x 22' x 10' with two openings into the kitchen, and one opening into a...

Someone else asked this on the soundillusions forum. Three main reasons I did (4) 15's: 1. It maximized the power output of my amp. I could have (2) 18's at 1100 watts each, or (4) 15's with 850 watts each. 2. I like watching multiple drivers move 2" peak to peak. 3. Chad already had dual...

In the front of my room, there is a 28" deep "void" that I built into the room to allow a cabinet for my 36" TV that would be flush mounted with the wall. On each side of that cabinet, I made a 28" H x 21" W opening. The DVD came from across the ocean. . . . I am an Electrical Engineer. I...

Avalanche 15 enclosure Remote linking not allowed on my freeservers account. Here is a link ot the picture!!!!

Hi guys, Finally finished my (4) 15" Avalanche 15 setup!!! Man is it wild. They are setup two drivers per cabinet, each cabinet is 5.25 ft^3 sealed and they are run on a QSC PLX3402, so each driver is getting around 800-850 watts. Like I said, it is amazing. It replaces dual Tumults on the...

My 4 will be here on Saturday (and the 18" for the car)!!! Brian

The link is just to the Tumult specs on the Acoustic Visions Website (where I bought them). The power listed above is just what I was driving them with, no amp is included. The enclosures are 2.5 ft^3 sealed and are just raw MDF right now. They are 1.5" thick except the front which is...

Shipping for the enclosure is from 76208, Denton TX. I would guess around 100-120 pounds. One Tumult and enclosure has been sold. One Tumult and one enclosure still for sale. Brian

I have (2) Tumults for sale. $350 EACH including shipping to the 48 states. Any other destinations, assume $325 + actual shipping charges. Excellent condition. Used for a little over a year in 2.5 ft^3 sealed with 1100 watts each. . . . These are from after the pre-order, so they have...

It is GREAT!! I just wonder how many people who bash XBL high excursion units have ever listened to one??? I have 18 subwoofers in my house and car right now. . . 4 of them are XBL and are being used in the HT and suburban. The other 14 are in the garage in their shipping containers...

This one has been fun on more than one forum!!!! Who is to say it is not a great driver, but the claims they make as the best in the world and the $1000+ price tag just make it unreasonable to most people. . .

Hey Thomas - Don't think Bill was really downing the driver, I just used it as an example, since I hear this about high excursion drivers all the time. I have seen it brought up more than once in discussions of the extremis 6". I have actually bought a couple of sets of Bill's plans for some...

I have a QSC PLX 3402 that I use on my Tumults. I was using one channel of it to drive the Avalanche. Brian

Have you seen this picture? I think it does near 5" p-to-p. Someone from RE posted it, and with CES in just a few more days, I would think you will see them coming soon. For WAF, grilles or downfire works great. I think my wife would like a black cone instead of a shiny cone...

I am 99% sure magnets are the same size. If I remember correctly, the top plate is not quite as tall. . .My Tumult is back in its home and is not coming out until it is replaced by a pair of Avalanches. I dropped the avalanche on the wood floor taking it out and made a nice dent. . . no more...

There are a couple of pictures on my website now: http://bkolfo4.freeservers.com/photo4.html Brian

I was going to post pics from work this morning, but my home email did not send them to my work email for some reason. . . Not sure what the mechanical throw is; I never asked Chad. I tried to bottom the driver last night with heavy rap music and 1100 watts, but could not do it. Even with the...

I received my Avalanche 15 last night!!!!!! First impression is WOW!!! I have two tumults, so I pulled one and installed the avalanche in place of it. The enclosures are 1.5" thick with 2.25" baffle with a net internal volume of 2.5 ft^3 sealed. Medium to heavy stuffing. Running side by side...

I have an Avalanche 15 on order and can not wait to compare it side by side with one of my Tumults. I will post the results soon after it is received. . . . Brian Owens
