Damn I am impressed and inspired to start work on my own in-wall project that I am dreaming of and researching still. It has different parameters but that build looks like it was hella fun!!!

There is a build that I've been thinking for many years but it has always been others in between. 


I'm incredibly glad I finally implementing the project.

Was really happy with the result.

Looking great Roger! I like the way you used splines to join the sides to the top/bottom and front! Very ingenious.

I have a couple of design questions/observations...I have built something similar a long time ago, and when I did it, I built it so the top and bottom were decorative caps...there was actually a hidden (functional) top/bottom which the decorative caps were screwed to from the inside. This made it much easier when it came time to finish the different parts.
Why did you put the speaker terminal cups so far apart as opposed to putting them right next to each other near the bottom?
Any reason you did not recess the drivers more (another baffle would have been needed)? I assume you want the drivers exposed? I know I recessed mine 1" deep just so I had a smooth front for a grille without the drivers hitting the grille.
How deep are the dados that you are using? Looks like about 0.125" although I could be waaaaayyyyyy wrong?

Again, I am not trying to nitpick. but the work looks great! I am guessing about 250-300 pounds each empty when they are done.

so nice, I love seeing diy tower builds. How are you finishing them, veneered sides and black painted front? How are you sealing the MDF seams?

I've had this idea a long time to build the tower and you know that is not really how 
something looks like the bow to get it together. 
But I'm really happy how the proportions were we are very sensitive to it.

The base change and I did so that it was possible to screw over before it became so heavy 
and difficult to assemble. 
The cover has a lot of beveled edges and you can not screw it inside from the 
it is bracing and insulation that is in the way.

 
Each box has its own box and I do not pull the cable existence inbetween for that then I have to make sure it is tight at each connection. 
I think having the elements visible because I have two Siberian cats who are interested in the front fabric. 
Then it will be a stylish connection rear of the speaker as I have never seen before.

 

 

 

The weight goes blank about 260 pounds but with the elements, it becomes a total of 400 pounds. 
It's just nice to have different solutions to their problems that's out there to learn.

 

Thanks

They're going to look like Revel Salon 2 

 

 

It gets to glue and use 4mm plywood strips that I put into the track that is 
the milled.

I'm thinking about possibly purchasing three emotiva XPR-2 to power my bass.
Why because they are incredibly much better looking than the PA amplifier and completely silent because the has no fan.
But I wonder whether there is anyone who has tested XPR to drive down to infrabas
If they manage to go down to 6-5Hz.
And if there is anyone who tested so you can read and I've already read from the test.
Audioholics and Home Theater and HiFi but like an independent test.
What do you think push my bass towers with?





And use this HiFi rack.

Power is power, I don't see why it wouldn't work. Probably more continuous power than a Class-D amp rated to the same.
That said, these amps require 20amp breakers and sockets. You'll need 3 of them.
Your power bill will be hefty, it will run hot, but it will look sexy and be noiseless.

Emotiva is pretty accurate on its amp specs from what I understand, so if it says it can do 5-10hz @ -3db, then you can believe it...

Also it should be noted that if you are an e-club member, you save 10-20%, or up to 70% in some rare cases.
If you phone them they might even give you a slight bulk discount as most people only buy 1.

Also the amps have clip indicators so you can tell if you are running out of power.
The other good thing is that they have a 30-day return policy, so you can get 99% of your money back if it doesn't work out.
(So make sure you pound the hell out of them for the first 3 weeks to ensure they are gonna work to your needs.)

Thank you.

For your thoughts about running the bases with Emotiva.
They consume around 200W per piece when they're just running, and three times = 600W

But I have a bigger problem that I think is a bit strange when things are all about business.
That you refuse to send any of the models XPR internationally because it is too heavy
and great ....?

But they send XPA-1 weighing and they have this quality:
size:
Unboxed: 17 "wide x 7 3/4" high x 19 "deep
Boxed: 23 1/2 "wide x 12" high x 24 3/4 "deep
Weight: 73 lbs (84 lbs boxed)

But they do not send XPR-2 weighing and measuring them here.
Dimensions:
Unboxed: 17 "wide x 9.5" high x 19.5 "deep (includes feet and Binding Posts; requires additional 3-4" of depth clearance to accomodate the power cord).
(double) Boxed: 27 "length x 25" width x 16 "height
Weight: 100 lbs (net); 114 lbs (boxed)

It is well just make a stronger case that the customer pays?

If such Mark Levinson had that attitude they would not sell many amps;-)

I have to have a middleman who orders and then send them to me.

A very strange way to solve if they now have had problems sending .... what does all
others who send larger and heavier items?

I already have D amplifier that drives Revel but I somehow love for
A / B-H power amplifiers, you know the old fashioned ..;-)

Tests on the XPR-1 if anyone wants to read .....

That's $4900 before taxes and shipping.

I calculated the shipping cost of 3 of them from north america to Sweden via FedEx. It estimated $4000. YIKES!!!

That's $9000 before taxes and duty!!!!


For that kind of money, you'd be better off buying 1 Lab Gruppen PLM20k and hiding it in your amp closet and run 6 8awg wires, to whatever distance that is.
WAY MORE power, comes with DSP, runs cool, 90% efficient on the power bill; they are made in Europe, about the same total cost.
WINNING Batman... WINNING!

http://labgruppen.com/products/plm_series_touring/

I think the amp can be bridged; and with dual tri's wired in series that would give you about 1200watts per sub, so 7200watts total.
If you run just one voice-coil of each sub it increases in power to 1600watts per coil, or just under 10kWatts total; which I am sure would blow the subs.

Or you could buy 3 FP14000's which would give you 4400watts per sub, or 26.4kW. Which would be even more over-kill!!! You'd have to upgrade to 6 LMS-18's...

Or you could cheap out and go with 3 Crown iTech 6000's. 3000watts x 6.
$1700 x 3
http://www.ebay.com/itm/Crown-I-Tech...item540a0a9bdb



I'm sure there are lots of local options for you with pro-amps, even class-H (but ugly and with fans),
big iron Hi-Fi amps... not so much.

Throw the ugly beasts in the utility closet.

When ordering from the USA so it is estimated about 10-11 times the dollar to Swedish money.
Type $ 1700 will be about 17,000 to 18,700 in Swedish money including everything.

I am looking for just about emotiva but there is one final step that I more or less thought to use.

It is inexpensive and has very good credentials and the use of 120 mm fan that one gets swapped out.
This makes it virtually silent.

It's Proline 3000 weighs 81 lb and costs 750 dollars but ugly as a beating.







I will drive a base per / channel into 4 ohms.

I will remove the handles and redo the pages and paint it as is silver / gray to black as well see them out pretty decent.

That you should never take anything for granted ...... now it went like clockwork to glue the first step of the box

We had major problems with the first box to get it together now turned out that the track was milled between the walls was 0.4 mm slim.

You should double check everything, it's just

I will build with copper pipes and press fittings as speaker cable to go through and
mounted on the back of the speaker.

Think it might be an odd assembly and a little cool.

Just remember that copper turns black or green over time.
