Why aren't there more 2x10 + 18 cabinets?

I had a Sonic 218 cab that I picked up for a hundred bucks and powered it with an Acoustic 270. It sounded cool; actually had some highs to it (they were more sensitive drivers) and could be heard down the block from my house. I wish I would have kept it longer, but I have different plans now and an 18" cab is not in them.

Why not discuss 21" drivers also? Is there a commercially available bass-specific cab with one in it?

I had one of those with the old Mark III head. Sold it to get my GK 800rb with a single 15" and a separate 2x10... At least with the bi-amping I could control the speakers and the crossover separately. Plus that 18" needed to be cranked to sound good without woofing out.

For me, personally, the 80's came along and bass became all about the growl. Ain't no growl in that ol' boomy 1810

The AccuGrove Whappo Grande is Bass cabinet with a 21" speaker:

From an acoustic standpoint, it's hard to get the 18 and the 10s to blend well using a passive crossover because the 18 is a lot slower than the 10s. If you biamped it and had some DSP, you could make it work well, but with added cost and complexity. The enclosure will be big and heavy even with neo drivers.


Pretty sure that 800 hz requires the speaker to move at the same rate regardless of the speaker size.

Peavey made a 15 and 2x8 also ...

since they're all basically 2 cabs in one bigger box ... they're just to heavy ..

the 18' usually sounded good in the very back of the room ... but were harder to hear on stage ... = long standing wavelength .. ?!
 
I was surprised by the post that they are re-making the 1516. So I checked out the specs and Peavey's claiming 450 W continuous which seems reasonable these days - the original, if memory serves, was only 200 W continuous. I'm not going to blame Peavey for my own ignorance prior to joining TB and getting an education on why I was blowing the Black Widow 15" on a pretty regular basis but my biggest complaint about this cabinet is having the 15" only an inch off the ground - forcing the uneducated to boost the volume in the hopes of getting warmth of tone. Anyone who buys this cabinet, do yourself a favour and put this cabinet on some stands to get it closer to your ear.
 
An 18 with 2 10s can sound stellar and the new 18s are fast and as articulate as an "old school" 15 as long as you use the proper 18. The mistake is using a driver voiced for FOH use. Use the right tool for the job. In the late 80s Celestion made K series drivers. They were voiced for synthesizers. The K18-300 had great bandwidth, was light, very tight and was a very good choice for bass. An 18 with 2 210s can come in under 65lbs, be portable, and move serious air. There are new 215 cabs out there weighing over 120 lbs that seem popular and no one seems to be concerned about the weight.
 
The 3620 cab sounded good when Bi-amped with a Max 800.
Bi-amping allowed you to blend the 10s with 18s and change the crossover point.
It was lacking if you used the built-in crossover with a single power amp though.
The built-in passive crossover was 500 Hz (and seemed to eat power).
I believe the Bi-amp jacks on the back bypassed the crossover
.
I had the 1820, and eliminated the factory x-over, and installed a 100hz filter on the 10's. This relieved the 10's of the heavy lows, and did help the overall sound. I still ran it with a single head (not bi-amped). I always wanted the 3620 back in the day. They did look pretty bada$$.

Apparently no one wants them, this was on the side of the road in the garbage in Rochester NY... I couldn't help myself. It's in my garage now. (Old peavey 1810)

Yep. Have a Peavey 18" Folded Horn cabinet the size of the Titanic in my backyard shed, way in the back, and don`t know what to do with the thing either. It may be too large for garbage pick up as my "1 extra item" at the curb.
 
As I look at those pictures I'm reminded that Peavey was using "multiple triangular ports" before that became a trademark feature thing (e.g. Mesa Tri-Port design). Admittedly it was probably done in a less sophisticated way than the modelling Mesa uses to locate and size their ports, but it was different than typical shelves and cardboard tube cylinders other cabs had at the time.

It'll be a project some day.

I'll load it, do some research on speakers for it, I have 2 Scorpions that'll fit, probably go with an eminence 18. Though about going with an ICEpower amp and make it self powered. It's a project now.
