Hi. I really enjoyed the discussions over my bass cabs. Using the handles as vents sprang from practical experience. I I made two bass cabs for my bands PA using 2 10” drivers I had purchased to replace 4 blown in an EBS cab. In the end EBS were so supportive and exported replacement drivers from Sweden at very reasonable cost so I was left with 4 10s.
I run the sound for my band and we needed some oomph but with low funds I had to keep costs down. The handles were initially a cost down but their performance on stage and the ease of pick up and carry led me to use the same principle for a 1x12 Bass guitar cab. Again the result was good and I was amazed that I could hear my bass over the “noise” of a 8 piece Funk band..
The first cab used the low cost driver you mention but it took a hammering and continued to perform amazingly for years so I tried to pass on the low cost option to other players. I’ve had good feedback and to date no failures so low cost but not “cheap”.
I have made a range now including 1x15, 2x6.5, 2x10 and 1x12. The switchable piezo tweeter I use follows many tests with larger bullets and dynamic horns etc but they were very brittle. I use bass drivers that have some natural top end (go above 3kHz) so the tweeter acts to support the top end not take the lot. Using the treble control on your guitar or amp and the switch provides full control over the top end.
I now have a new range soon to be available through the Great British Bass lounge ( only deliverd this week). Apart from the 6.5s they are all Neodymium and they sound amazing. Sadly the cheap but cheerful will go after I’ve sold those few on e bay but they really didn’t deserve to die. FYI the new 12s are Faital Pro’s (first time of using) and I’m very impressed with these drivers.
As a footnote: following years of agony over my sound and poring over technical details I have found something good using instinct and testing and practical use. I’ll take anything back you don’t like. Test if you can but give the eBay 12s a try if funds are short. In all enjoy your bass playing. These cabs help add to the fun.
