Mass loading taken to ridiculous lengths

nathanm · « **on:** 19 Feb 2004, 03:53 pm »

Here's a general question which is slightly idiotic and whose answer should be self-evident, but I'm asking anyway for the heck of it.

Would it be structurally sound to take a VMPS New Larger subwoofer, put a chunk of foam, rubber or board or something on the top and then on top of that set a 187 lbs. speaker? I am contemplating the purchase of a very ginormous pair of monitors and since I already have one VMPS sub I figure with two of them they'd make swell stands and save me a bit 'o DIY stand-making effort. That and the height is probably just right.

So is that a bearable load for ye olde MDF footer doohickey or am I crazy?

I REALLY want to see a picture of a 187 lb. monitor. Got one nathan?

i have a marble top on my large that goes about 80lbs(2 sheets 1" mdf and 12x12 marble cut to fit edges trimed with oak), and put a 60lb speaker on top of that-no problems-well one problem -when you crank a bass track the speaker walks-

i would at least use some 3/4 mdf on top to help spread the weight of th speaker so the cabinet doesnt cup in the middle from the weight of the speaker-maybe contact the new wood guy and have a solid maple top made

Tannoy System 215 DMT IIs. Normally seen soffit-mounted in control rooms, but that of course won't be possible in my case.

I figure this bad boy crossed over way low to the largers will be mighty ass-kickin' but hell who knows they might not even need a sub. Mainly I am just concerned with the weight factor.

better hope you get speaker placement right the first time if you use a large for bass and base

thats a lot of friggin weight

I have 2 95# Dumbbells (total 190#) sitting atop my Larger with no problem and have been advocating such for some time now.

Talk about tight, musical bass....

I have it mated to my 626Rs and sloped in with the new NHT X-2 crossover I have been slobering about, with excellent integration and "super" BASS exactly in the sweet seat.

Weighting your woofer cabinets is highly efficacious, the more the better. A sub can handle about 500 lbs of added weight.

Thanks Brian! That is good to know. The only bummer thing about this idea is that I'd be covering up the nice glossy black finish!
