Dear lumpini49,

We can arrange to deliver the cabinets via air freight by HK post office to Cambodia. The air parcel postage rate is USD35. The total price is USD80+USD35=USD115.

Thanks.
Tony.

Tony, have you tried a sealed cabinet for the CHR70? From WinISD, they seem to work pretty well indeed. A 6L cab gives you 66Hz @-6dB and at the same time you can have much lower group delay. I am sure Mark would trade the group delay for more bass, but in a HT setup or if you've got a decent sealed sub, a sealed cab will perform much better.

Regards,
Boris

HI Boris,

I never tried a sealer cabinet for CHR-70. Can you upload a picture or drawing of the sealed cabinet for sharing?

Thanks,
Tony.

Tony, this is my sealed cab design for the Markaudio CHR70. I haven't tried it although I would like to one day. (I had never built a proper cab, just some junk random projects), and I would be delighted if you can try it. Internal volume is 5.7L, the walls should be strengthened by bitumen pads as the walls are on the thin side. I would recommend the use of ply wood over MDF in this design. From the prediction of WinISD, you can get a f3 of 88Hz, f6 of 58Hz. With a bit of equalization, it works as a fine desktop speaker, and with a sub and AV receiver, you can have an excellent Home Theater system if you mate it to a decent sealed sub (maybe Peerless XXLS series with BASH amp).

Have fun! ( You can of course produce this model if it's great, but please inform me first!)

Hi Boris,

The sealed cab design looks good. Can ask Mark Fenlon. Mark has lots of knowledge and experience on cabinet design.

Thanks,
Tony.

Well done, Tony. The woodwork is excellent, especially the edge rounding on the front baffle. BTW, did you leave the "scars" of the joints on purpose? You can still see the joints on the top clearly.

Hi Boris,

Unlike cabinet with veneer, the joints on natural wood are not covered and can be seen. See the right Japanese white birch cabinet, the joints on top are special and perfect.

Tony.
