Is anything in stock, or do you make everything to order?

We do keep some popular items in stock, but many of our clients ask us to make their system fully from scratch, because this is also a service we offer, understanding that this does involve a brief waiting period while their order is being built and tested before it can be shipped direct from our wood shop.  Often times, we are able to ship out certain items that might happen to be in stock first, and then fulfill the remaining items in the order that they are produced and pass quality control.   

If you want to order speakers and have them ship fast, please call (206) 407-8439 (or email to check the limited quantities of inventory we may have on hand and ready to ship.   

How do your production processes work?

As designers and builders of products with unconventionally long lifespans, we primarily honor the potential of the materials to attain their highest quality via our hand production processes - which in some cases involve parts supplied from friends-in-the-business with similar hand made production schedules as us.

We have been honing our manufacturing and quality control practices for over 10 years into a revolving batch run system, our batch run method is both responsive to our online and over-the-phone order board system as well as the needs of the shelves of our storefront in Tacoma, WA.

We always go a little above and beyond the order board's needs during any given production batch, so each batch typically includes several extra pieces in popular finishes for our store's inventory.  We also sometimes experience loss of product in production due to imperfections discovered in the wood during the last stages of production.  

If you have ordered an item that needs to be built before it can ship out to you, this can typically take anywhere between 2-8 weeks.  We are happy to provide you with an estimated time frame until delivery at any point along the way.  We will always do our best to meet our own deadlines, but our delivery estimates are non contractual and non binding and cannot be used for any legal purposes.  We focus our resources on the core build quality, friendly advice, and prompt, over-achieving customer support that have driven the word of mouth building our community for over 10 years.  The finished products will last generations after they've been skillfully, patiently made at every step.

Natural Variation

We apply an industry-leading standard of quality to everything we make and ship, but there are minor variations between each cabinet due to the eccentricities of bamboo and wood grain and color.  Each batch is slightly unique. However, the slight eccentricities do not affect the sound quality and make each piece slightly unique - just like our thousands of happy customers! 

What happens if my order arrives damaged?

Please first take photos of both the box as it arrived and the damage incurred on your order. Depending on what you ordered, we may want to send you a replacement, arrange for shipment back to our shop for a repair/replacement, or make other arrangements. If we decide that your order should be returned, we will send you a shipping label to affix to the box for return shipping. In any case, rest assured that we will get your order fixed up good as new as quickly as we can.

Returns & Exchanges

We can accommodate refunds if you are dissatisfied with one of our product's performance within 60 days of receiving it. You will be responsible for covering your own return shipping charges and up to a 5% restocking fee - only to cover merchant services like credit card or paypal fees (that we pay when we accept your credit card, paypal or etc payment at the time you initially ordered).  If the product is received back with damage, an additional restocking fee may apply. Once your returned item is received back at our shop, it will be inspected for damage before the refund minus restocking fee is sent to you.  

Items purchased on sale, as b-stock, or custom items are non-returnable.

We pack our products very carefully.  But in the extremely rare case that your order arrives damaged from shipping, we will work with you promptly to get an exchange for new gear coming your way.  Please take photos of the box as it arrived and any damage on the product itself for claim purposes with the mail carrier. 

Exchanges on products can be made within 60 days of receiving them for products of equal value, or used as credit towards products of greater value.  Restocking fees do not apply during exchanges. Please note that we do not exchange discontinued models towards current models. 


During production: If circumstances arise that require you to cancel your order before it has been shipped, we understand and you can do so. We do charge a higher 15% restocking fee to cover the work that's been done on an order that is cancelled during production, unless you cancel within 5 days after ordering, in which case only the merchant services (up to 5%) restocking fee may apply.  

Please note that we do not require a 15% restocking fee on orders that have been received, opened, and listened to for some part of the 60 day auditioning period by the client, unless that order is received back damaged.

Cancellations of custom items, customized orders, or custom requests, installation, or consultation services billed hourly, not sold through our web store are non returnable / non refundable under any circumstances.

We reserve the right to refuse service to anyone.
