Hi guys, just thought I'd share my simple sealed subwoofer build with you all.
The cabinets are small 30cm cubes and are constructed from 18mm Baltic Birch. All panels were CNC'd with mitre joints and channels for the interior window braces. This style of assembly meant that:
A. I could assemble the box in one go, keeping clamp time down to half an hour per box
B. There were no visible joins of the wood, making the paint job significantly easier.
The total cost of this work was £380 from ProCarve UK. Please bear in mind that they managed to cut 4 cabinets from one sheet, but only 2 have been built so far (2 is already more bass than I need).
The drivers are the Peerless XLS P830452 bought for £130 each from DigiKey. These are probably some of the most, if not most popular 10" drivers across both commercial offerings and DIY jobs. They offer a very nice balance of price-performance and I think they also look badass. They are secured using insert nuts and bolts rather than wood screws, which aid massively in removing the driver in the future and also feel much more secure.
The cabinets also use Neutrik Speakon connectors which I find are the best for quick removal and plug-in. These are the common method of plugging for pro audio gear, but I am seeing more and more home oriented gear using this method too.
For amplification I am using the Thomann T.Amp E1200. This amp provides enough power to run one sub per channel, or 2 subs in parallel per channel. Even though the Peerless are advertised as 4ohm, they only dip to 4ohm way below Fs, staying above 8ohm for the majority of the musical range.
For paint I used matt spray paint from ebay. Around 2x500ml bottles were needed for the pictured finish, which has come out significantly better than I imagined.
The rest of the system is an Okto DAC 8 (also running the DSP), Wiim Ultra, Genelec 8350a's and LG Oled 65.
Total cost including wood, drivers, amp, connectors, wiring, internal wadding, screws and paint was £922. This however could be £1082 for 4 subs vs just two (as above, two extra cabs and two subs per amp channel). For just two subwoofers, you can probably get a pair of used SVS for the same price and save yourself the trouble, but at 4 subs for just over 1k it becomes tougher to beat.
So far I am more than happy with the bass performance in the room now!
PS: The bass region as pictured has been reduced 3db as on bass heavy content it was a little too much. This was also a single point measurement so the full frequency range doesn't paint an accurate picture. Subs crossed over at 120hz LR4.
