Jimryan Posted January 12, 2013 Share Posted January 12, 2013 Evening all, I've been using my home built 1x15 for a while now. The cab itself is quite large and heavy, so was considering whipping out the driver and cables and installing them into a smaller, more portable, back friendly cab. What would the smaller dimensions do to the overall sound? It's currently slightly larger and deeper than a Marshall 1x15, I'm thinking of going down to something the size of a barefaced compact.

TimR Posted January 12, 2013 Share Posted January 12, 2013 Did you build the cab yourself? Do you have any info on what the driver is? If you can find the Xmax and Thiele-Small data, you can use them in software like WinISD to model different cab sizes and predict what might happen. Also is it a ported/vented cab? The above data might also help in deciding whether the speaker would suit a ported or sealed cab. Gererally (ouch!) you'll lose bass as the size of the cab reduces. Hours of fun ahead Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted January 12, 2013 Share Posted January 12, 2013 For Barefaced Compact size to work, need a Barefaced Compact typed river, about £175 for a driver. Quote Link to comment Share on other sites More sharing options...
Jimryan Posted January 12, 2013 Author Share Posted January 12, 2013 I sorta did. The chippies on site built a concrete shutter, it wasn't needed so I pinched it, made a few alterations and hey presto, bass cab. The driver's a car sub. All I know about it, is its a dual voice coil (?), its 15", it's rated at 1400w at 4ohm and it's bright orange. The cab is ported at the moment. Xmax? Thiele small? That makes sense as at the moment it's really REALLY boomy. When using it, the eq on my amp has to have the bass reduced considerably, but the cab does a really good Motown kinda sound.

TimR Posted January 12, 2013 Share Posted January 12, 2013 If it's a sub I doubt any size can will make it do higher frequencies. It's designed to do bottom and nothing else. Try to google the sub manufacturer and dig out a data sheet. Building a cab is not just a case of building a box, cutting a hole and putting a speaker in. Check out the DIY cab thread.

Jimryan Posted January 12, 2013 Author Share Posted January 12, 2013 Not really after altering the sound to enhance frequencies, just trying to make it more manageable. I know what you mean, there's a fair bit of science involved. For me its a way of having a cab when I can't afford to buy one. Quote Link to comment Share on other sites More sharing options...
TimR Posted January 12, 2013 Share Posted January 12, 2013 Have a look on the back of the speaker and see what is written on it. Maybe someone here can dig something out and recommend a cab size. If you're getting the saw out might as well try to get the best sound you can. Quote Link to comment Share on other sites More sharing options...
Jimryan Posted January 12, 2013 Author Share Posted January 12, 2013 It's a legacy "predator" series speaker. True, I won't be doing any cutting though. Not all the time there's a joiner or a chippy on site anyway. Quote Link to comment Share on other sites More sharing options...

Mr. Foxen Posted January 12, 2013 Share Posted January 12, 2013 [quote]SPL @ 1W/1M: 86dB[/quote] means pretty much not worth bothering with. Quote Link to comment Share on other sites More sharing options...

xgsjx Posted January 12, 2013 Share Posted January 12, 2013 See if you can sell it to a boy racer & have a look in the "Cabs For Sale" section on here. Should be able to get something better for less than £100? Quote Link to comment Share on other sites More sharing options...

Needed a cab, needed one cheap and wanted it loud, Had the box readily a available and it all kinda came together from there. Quote Link to comment Share on other sites More sharing options...

[/quote] Means it needs 8 to 16x as much power to reach the same volume as a fairly basic suitable for bass guitar 15" driver. The DB rating is how loud it is with 1w of input power. The Eminece Delta 15, which is in the scheme of things a cheapy, has 100db sensitivity, and you need to double power to get each extra 3db.

Jimryan Posted January 12, 2013 Author Share Posted January 12, 2013 Ah right. So, in a nutshell, don't bother, wait until I can eventually afford a small, decent cab? Quote Link to comment Share on other sites More sharing options...
Prime_BASS Posted January 12, 2013 Share Posted January 12, 2013 [quote name='Jimryan' timestamp='1358033257' post='1932267'] Ah right. So, in a nutshell, don't bother, wait until I can eventually afford a small, decent cab? [/quote] Yes. Lot's of stuff out there even brand new that are cheap as chips and will be a lot more suitable for the job. My cabs for example. Weigh 11.4kgs each and go pretty darn loud, sound pretty decent, and I'm selling for less than £200 each. Quote Link to comment Share on other sites More sharing options...
Guest bassman7755 Posted January 13, 2013 Share Posted January 13, 2013 (edited) That driver you have looks like a decent ish spec car subwoofer so I would be tempted to try to sell it - you might get £30-£40 for it say which, plus the price of a few rounds of beers, puts you in the running to maybe get something like this [url="http://www.ebay.co.uk/itm/Ashdown-2x10-Mag-II-250W-Bass-Cabinet-/160952914333?pt=UK_ConElec_SpeakersPASystems_RL&hash=item25798a919d"]http://www.ebay.co.u...=item25798a919d[/url]. Even the cheapest "proper" bass cab is going to destroy your homebrew thing for tone. Edited January 13, 2013 by bassman7755 Quote Link to comment Share on other sites More sharing options...
