Kevin had a brief sale on 21" Mal-X drivers, since the 18" drivers were unavailable. I couldn't resist, so I bought one. I waffled back and forth A LOT between a sonosub and a MDF cabinet. I finally found a good supplier for 28" sonotube and then decided to go the MDF route because at some...

The $469 price for the 21 is the DR motor – which is a 7.5” triple stacked motor, very beefy. On the IB 21 – T/S are: Fs: 21 Hz Qms: 8.08 Qts: 0.67 Qes: 0.73 Mms: 419 g BL: 15.35 Vas: 372.7 L SPL: 90.5 1w/1m

I'm thinking about a build with a 21" Mal-X. My first reaction was to build a sealed cabinet - because I've been very happy with the performance/sound of 6-8 cuft sealed cabinets that I've built. That...and I love sub 20hz content (below tuning point of most ported). But, every time I model...

So I have a Mal-X 21" and an EP4000. Would like to build a sub. I am no good building boxes so I will use sonotube and I am thinking sealed. QUESTIONS: What size enclosure so I do not need HPF, if possible... Wired series, parallel, bridged amp etc. Anything else you would do? Thanks in advance.

A few months ago I bought material (BB ply) except the woofers to build the Maelstrom 18" with 2 PRs. But i am having second thoughts since the PR price has gone back up. Now this is going to be used in a 120 sq ft room for HT. I think I may want to try a sealed 21" because it is easier to...

Interested in your thoughts regarding using the 21"s with pr-18 passives to build two Subs ?.. Maelstrom 21" + 2x PR18 passives per 9-10Qft box & the max recommended 1500g mass per passive, Has any one gone this route.. I am Going with A Pair of Maelstrom 21" to go with my Maelstrom-x 18" +2x...

1st off.....this is my first build. :o Second.....I'd like to thank NeoDan, bossobass, Kevin Haskins, and anyone else I've pestered via PM's asking for advice. Third.......Please don't hesitate to ask me any questions......as there is probably some things I've not thought about or just don't...

Hi there, I have been thinking over the last few days about how a single 21" maesltrom slot ported or with PR's would compare to both my FI Q18 subs for output and SQ. Would I gain alot more output. I could afford to sell both my drivers to get one of the 21"'s. Here's a pic to show them...

I was just curious as to others opinions on the suitability of this sub in IB? I am planning construction of a HT in the basement and am trying to come to a consensus on what to do about subs. Goals are to get very low and be reasonably clean. This room would be used mostly for movies and...

Hello all, Essentially building my first HT sub (built them for vehicles in the past...) and am looking for some advice. I havn't used winisd in over a year now and am not particulalrly anxious to stumble through it again, so, I'm asking for some options in build design that would be "ideal"...

I ordered an extra woofer for a spare and now need to sell it due to the lack of work with my full time job. I purchased it new from Kevin/Exodus Audio a couple of months ago and am offering it for sale at $550 with free shipping to the lower 48. I took it out of the box to ohm out the coils...

So I'm going to guess the Maelstrom is more efficient, ignoring both driver's efficiency and sensitivity ratings, as it has a much larger cone and seems more efficient in build... light paper cone, light foam surround, not over built... smaller Sd with larger roll surround than needed. trim...

After all the talk, it is a go! I got finances lined up, just gotta dot T's and cross I's! hahaha..something like that. So do I: a: wall 4 21" Maelstrom-X's or b: wall 3 DTS10 Super Spuds? That's just for the car! For my home, 2 21" Maelstom-X's each in 128 cubes tuned to 15Hz with a 16"...

And with these photos I officially start my build thread! You really don't understand how big this woofer is, till you see it in person. It's so big, it's almost perverted. :bigsmile: I've got two other projects going on right now, I'm going to push one off, but I have to finish the...

OK, Kevin has talked me into (read upsell (also read - he didn't have to push too hard) buying a 21" Maelstrom-X and building a sealed box over going with a ported 18". My current setup is a Wicked One folded horn with a pair of JL Audio 10" drivers...which sounds great, but it drops like a rock...

I'd love to be the first, but budget and (limited) space are making me think the 18" is going to be for me. I'd love to live vicariously through some 21" build threads though!! Who knows, maybe someone can talk me into building a 21, for better or worse. :sn:

Just curious, wondering what sort of results one can expect with a single 21" bass driver for a subwoofer? I have noticed a few while looking for my budget drivers, though expensive do they offer more than a pair of 15" or 18" drivers? How does a 21" sound? Is it slower with less slam, any sort...

For those interested in IB, Incriminator Audio has come up with a new 21" driver that they are hoping to bring to market if there is interest. You can see the parameters and discuss it in the following thread: 21" IA IB Subwoofer

Hello everyone... glad to be here at the Shack! We have been experimenting with a few projects and recently developed what we believe will be an excellent 21" IB driver. We realize this is a limited market, but it is all in good fun and we would appreciate your feedback. :yes: Here are the...
