Show what your cabs look like on the inside

[billfitzmaurice]

the point is that in a sealed cabinet the speaker will "see" the cab as being larger in volume then it really is, so you can get away with a smaller cabinet.

-1, but you're not alone in this misconception, even the esteemed Vance Dickason only recently recanted on this point. Dense stuffing of a sealed box that's too small reduces the box Q, which in turn reduces the midbass response spike that results from too small a box, taming a boomy response. Making the cab larger also reduces Q, so in that fashion stuffing emulates a larger cab. But a larger cab also extends bass response and improves system efficiency, stuffing doesn't.
OTOH the pictured TL806 is a vented cab, and it should be lined, not stuffed. Stuffing a vented cab reduces LF output.

Here's a shot inside my ported 212:

That doesn't look a whole lot different than the picts I've seen of the moon, LOL. Only the sky is different.

Thanks for the pictures!



Too bad, those would have been interesting to see.



Care to elaborate?

Do a search, there are pics. Mine were similar. I do not care to elaborate, as it leads to a less than focused thread. I'll check for pics on my b/u hard drive.

The tl806 wasnt my creation. My former singer built 4 and we used them for PA mids and then sold them off for use as guitar cabs etc. i used it as part of my bass rig for a bit. it was stuffed chock full of pink stuff for sure. Regarding low frequency loss, it wasnt there to begin with with that cab.

The modded PV cab was lined with whatever I had laying around. the goal was CHEEEEEP. I used some wool batting from an old hot water heater blanket as well. And the purple is strips cut form a yoga matte. Oh, its ugly inside for sure. but for what it is (small 1x10 full range cab) it sounds VERY nice. total cost including driver was maybe 80 bucks I think. I dunno. it wasnt much.


The ampeg 210 cab was lined, not stuffed. The schroeders were unlined and unstuffed.

never seen ampeg stuff a cab ..... or ashdown , gk , peavey , or really anyone who makes a sealed bass enclosure ... looks more lined to me .

Many of the big manufacturers are motivated by cost of material/labor, not proper design.

My old straightback 810 is stuffed, and most Ampeg 810's that I've pulled a speaker out of are stuffed as well, although it wouldn't surprise me if they decided to line recently because it's $2 cheaper. LOUD IS a company of idiots.

Ok, I've got a new one for you, a Gallien Krueger Backline 210 BLX-II.

It's a sealed cabinet, same 19mm (3/4") MDF as the 115 but obviously no ports. It's got a "wall" in the middle as bracing, however it does not seal the drivers into two separate chambers, there's a quite large hole for the wiring. The cabinet is lined, not stuffed.

The Backline Series seems to be quite well built especially considering it being a budget alternative. Probably adequate amount of bracing, even if it could have been made lighter as greenboy suggests.

I might have an Acoustic 406 2x15 and maybe a Marshall JCM800 2x15 coming up for you. Please keep posting pictures.

bgavin, the Omni looks great. I wonder how many commercial cabs there are keeping the same standards.

I will take a picture of an ampeg cab for you guys tonight.

Right now, I have my BXT 1x15 opened up because I need to put a new speaker in there.


not to thread jack, but what a time for the LOUD assistance tech people to be off on training and can't help me to order a replacement!!

Mailbox is full for Loud Technologies Re-supply/Order parts section of the company.

That doesn't matter anyway. Two drivers in one space double the size is for all intents and purposes the same as one driver in half the space * 2. But as a separate issue it wouldn't hurt to moderately stuff that cab perhaps.

The Backline Series seems to be quite well built especially considering it being a budget alternative. Probably adequate amount of bracing, even if it could have been made lighter as greenboy suggests.

Another flaw is that the port is directly in back of the driver on that 15.

Very few. Practially every commercial cab I've opened needs to be fully lined instead of partially or "not at all". That's a buck shaving issue in materials and labor.

Impressed with the construction of those Backline cabs - some of the big names should take note!

i did notice the newer 810s sound like garbage compared to mine, with less bass response, punch, and volume. Maybe it has something to do with that ...

dont worry jimmy, this will be one of the first things you and I fix

The sweet sixteen.

Used to be a Radio Shack Musical intrument cab. Built it
in the 80's, rebuilt it to a bass cab in 2005 with help from
BillFM, PeteBass and a host of other advisors.

Pics were lost on the thread in a subsequent TB software upgrade.

Inside of an Avatar B210 I modded. I added a Selenium horn and DH200E driver and a 3000hz third order crossover and some extra bracing.

Doesn't seem to bother the Bag End S15-D!

Plenty of posts around on why port right in the back of the driver isn't such a good idea. And as one not all that fond of that cab, I have to agree.

I think this cool thread should get a bump for new submissions.
