greentext Posted February 20, 2023 Share Posted February 20, 2023 (edited) Does anyone else turn there cabs with casters on there sides so you can feel the bass a bit more? As much as I love the convenience of casters on my cab, I feel like i lose a lot of the 'feel' of the bass, pushing air, when its only connection to the stage/floor is the 4 wheels.

Bill Fitzmaurice Posted February 20, 2023 Share Posted February 20, 2023 It makes no difference. The connection to the floor which gives boundary loading isn't mechanical, it's acoustical. 1 Quote Link to comment Share on other sites More sharing options...
greentext Posted February 20, 2023 Author Share Posted February 20, 2023 defo feels different to me, but thanks for the input my duder Quote Link to comment Share on other sites More sharing options...
fleabag Posted February 22, 2023 Share Posted February 22, 2023 Thats because you're not an objective listener. Bring a mate round to do a blind test. Dont tell him / let him see which way you've set the cab and play through it, first on the castors, then off the castors. 2 Quote Link to comment Share on other sites More sharing options...

chyc Posted February 22, 2023 Share Posted February 22, 2023 (edited) Depending on the layout of the cabinet, placing it on its side may move the woofer significantly closer to the floor. That can have a difference to the sound. Similarly if there's a tweeter with different vertical and horizontal dispersion patterns.

Is the OP perhaps getting a different bass response because the driver is closer to the floor when the cab is on its side? Or does that make no difference either? I've wondered myself what the effect of raising or lowering my cab is (Barefaced Super Compact 1x12), and if sitting it 'landscape' or 'portrait' makes any difference.

Bill Fitzmaurice Posted February 22, 2023 Share Posted February 22, 2023 Only if it's 40cm or more closer, and that wouldn't affect it down low. You get full boundary reinforcement when within 1/4 wavelength of the boundary. 1/4 wavelength at 100Hz is 85cm, and the lower you go the longer a wavelength is.

Steve Browning Posted February 23, 2023 Share Posted February 23, 2023 For years I always removed anything between the cab and the floor. After getting a 2x18 that was immovable without I indeed found there was not the blindest bit of difference. Years of shifting utterly wasted. Get some decent 10cm casters with brakes and don't look back. 3 Quote Link to comment Share on other sites More sharing options...
Dan Dare Posted February 23, 2023 Share Posted February 23, 2023 If you're bothered about it, you can get removable castors that push into a plate mounted on the cab base. My old Bassman 2x15 had them. Quote Link to comment Share on other sites More sharing options...

Get some decent 10cm casters with brakes and don't look back. By the same token isolation doesn't work either. Isolation can reduce the vibrating of a cab atop a soft floor, which is vibrating as the result of acoustic resonance excited by the speaker output. What it can't do is reduce the vibration of the floor, as that's acoustically sourced, not mechanically. http://ethanwiner.com/speaker_isolation.htm https://www.bassgearmag.com/submit-article-bass-amplifier-isolation/ Quote Link to comment Share on other sites More sharing options...
Lfalex v1.1 Posted February 23, 2023 Share Posted February 23, 2023 If a cab has casters, leave it standing on them. Reason? They have a tendency to rattle when you play. Whether that's mechanically or acoustically generated is irrelevant. It's annoying! 1 Quote Link to comment Share on other sites More sharing options...

BassmanPaul Posted February 23, 2023 Share Posted February 23, 2023 Whatever the cab is if it has a pair of drivers stack the cab so that they are vertically aligned. It's better that way. Quote Link to comment Share on other sites More sharing options...
